Executive Summary
SunHeat Solar Water Solutions (Pty) Ltd (“SunHeat”) delivers solar water heating systems that reduce household and facility electricity consumption while improving hot-water reliability. The company is incorporated as a Pty Ltd and operates in Johannesburg, Gauteng, South Africa, serving customers across Gauteng and nearby commuting areas where logistical turnaround time, installer capacity, and service density remain strong. SunHeat installs and commissions solar thermal systems end-to-end: technical design and sizing, supply of components, roof and plumbing integration, testing, and handover documentation, with maintenance options to support long-term performance.
The problem and why customers pay
South African electricity price increases and supply constraints have heightened both the cost pressure and the value of dependable hot water. In Gauteng, solar water heating adoption is constrained less by awareness and more by execution risk: poor installations, unclear system sizing, inadequate plumbing integration, and weak commissioning processes lead to early underperformance and customer dissatisfaction. Many prospects are willing to consider solar but only when they believe the install will work reliably, will be correctly sized for real hot-water demand, and will be supported with quality checks.
SunHeat’s positioning is built on three practical promises that directly address these pain points:
- Transparent sizing and configuration aligned to customer hot-water needs.
- Clean roof and plumbing workmanship, reducing leak risk and performance degradation.
- Documented commissioning/testing so the customer can trust the system at handover.
What SunHeat sells
SunHeat’s commercial model is based on once-off installation packages with optional ongoing service plans. Customers purchase a system package selected by expected household size or hot-water demand. SunHeat earns revenue from installation and supports long-term performance through repeatable maintenance processes and service follow-ups.
The packages are designed for clear market segmentation:
- Package A: 200L Evacuated Tube System (3–4 people)
- Package B: 300L Split System (5–6 people)
- Package C: 500L Commercial/High-Demand System

Company Description (business name, location, legal structure, ownership)
Company overview
SunHeat Solar Water Solutions (Pty) Ltd is a solar water heating installation and commissioning business operating in Johannesburg, Gauteng, South Africa. The company serves residential, small commercial, and community customers who want to lower electricity usage and secure dependable hot-water delivery through solar thermal technology.
Solar water heating is a system-dependent product: performance is influenced by correct sizing for household hot-water demand, roof mounting integrity, plumbing integration (including temperature/pressure and flow design), and commissioning/testing. SunHeat’s operational approach is therefore structured around repeatable installation steps and technical validation.
Location and service area
SunHeat is headquartered in Johannesburg, Gauteng, South Africa. The business plan focuses on a Gauteng-dense service area where:
- Travel time and job scheduling are manageable,
- Supply delivery and installation team coordination remain efficient,
- Local SEO and trust-building campaigns translate into stable lead throughput,
- Service and warranty expectations can be met with consistent turnaround.
Legal structure and compliance
SunHeat operates as a Pty Ltd company. The business is registered and compliant with CIPC and trades in ZAR only. This legal structure supports investor confidence, contractual enforceability with suppliers and contractors, and clear financial reporting boundaries aligned to forecasted P&L, cash flow, and balance sheet statements.
Ownership and governance
SunHeat’s leadership is built around financial control, technical design, installation quality, procurement reliability, sales/customer onboarding, compliance safety, workshop efficiency, and marketing execution. While ownership shares are not specified in the model input, governance responsibilities are clearly assigned among named executives and managers (see Management & Organization section).
Business model logic
SunHeat’s model is designed for both profitability and cash-flow integrity:
- Once-off installation packages drive main revenue.
- Installation delivery is planned to reduce idle time: job scheduling is aligned with procurement lead times and installer capacity.
- Customer payment structure protects working capital by taking deposits prior to full installation completion.
- Ongoing service plans create a secondary customer relationship channel and reduce customer churn in the early years, supporting recurring revenue opportunities beyond installation.
Strategic positioning in Gauteng
SunHeat competes in a market where many installers price aggressively, sometimes at the expense of correct sizing and commissioning/testing. SunHeat positions as a “proper install” provider—transparent sizing, clean workmanship, and documented performance checks. This approach:
- Increases close rates among customers who have experienced poor installations,
- Improves referral likelihood because customers can trust the quality assurance,
- Reduces rework and warranty-style follow-up caused by preventable installation errors.
Investor-ready operational credibility
SunHeat’s five-year forecast is supported by model-consistent cost structure discipline:
- COGS is held at 38.0% of revenue across the forecast period.
- Gross margin remains 62.0% across Years 1–5.
- Operating cost categories—salaries and wages, rent and utilities, marketing and sales, insurance, administration, and other operating costs—scale with revenue growth patterns.
- Interest expense decreases over time as projected leverage and financing structure settle into lower annual interest burdens as model inputs indicate.
This combination of consistent gross margin discipline and controlled operating cost growth underpins the projected EBITDA and net income trajectory.
Products / Services
Core offering: solar water heating system installations
SunHeat sells solar thermal water heating systems as complete installation packages. Each package is configured to match customer hot-water needs based on household size or demand profile, ensuring that customers receive a system designed for their actual usage rather than a generic “one-size-fits-all” solution.
SunHeat’s deliverable includes:
- Site assessment and technical design
- System sizing and specification confirmation
- Procurement and supply of components
- Roof mounting and collector installation
- Plumbing integration (pipework, valves and required connections)
- Control and safety integration (controller configuration and system checks)
- Testing and commissioning
- Customer handover with documentation and operating guidance
This end-to-end delivery is critical because solar performance depends on installation quality; suppliers alone cannot guarantee performance. SunHeat’s commissioning/testing standard reduces performance disputes and increases customer confidence.
Package A: 200L Evacuated Tube System (3–4 people)
Package A is designed for smaller households requiring reliable hot water for daily routines. The value proposition is balanced: it is typically selected by customers who want effective solar hot water coverage without the cost intensity of larger systems.
- Intended occupancy: 3–4 people
- System characteristics: 200L storage with evacuated tubes suited to efficient solar heat transfer
- Install scope: roof mounting, collector integration, tank and controller setup, plumbing integration, and commissioning/testing documentation.
SunHeat’s installation playbook for Package A includes standardised checklists at three points:
- Pre-install roof readiness verification,
- Post-mount alignment and seal verification,
- Post-plumbing flow validation and controller commissioning checks.
Package B: 300L Split System (5–6 people)
Package B targets medium-sized households and small landlords where usage needs exceed Package A capacity. The system design addresses higher demand while maintaining maintainability and installation feasibility in typical Gauteng residential roofs.
- Intended occupancy: 5–6 people
- System characteristics: 300L split system configured for practical installation and consistent hot-water delivery
- Install scope: collectors and tank integration, plumbing integration, and system commissioning.
SunHeat treats Package B as a common conversion package due to the large segment of Gauteng households that fall within this usage bracket. Because many customers compare solar solutions across price points, SunHeat’s transparency on sizing and performance expectations helps close deals by reducing uncertainty.
Package C: 500L Commercial/High-Demand System
Package C serves customers with higher hot-water throughput needs, such as churches or facilities with consistent usage patterns. The commercial system is designed for demand durability and system resilience to higher daily hot water usage.
- Intended demand profile: high-demand facilities
- System characteristics: 500L commercial/high-demand configuration
- Install scope: a more intensive installation workflow including larger-scale mounting and plumbing integration, plus extended commissioning and performance validation steps.
For investors, Package C matters because it increases average project size and supports scaling revenue without needing proportionally higher customer acquisition volumes.
Optional add-ons: service and maintenance plans
While the primary revenue driver is installation, SunHeat offers optional annual service plans to support long-term performance. This service model is particularly valuable in South Africa’s climate variability and because solar thermal systems require periodic checks to maintain performance consistency.
Service plan activities include:
- Visual inspection of collectors and mounting integrity
- Control and temperature operation checks
- Plumbing and valve inspection for leaks or flow restrictions
- System performance verification against commissioning baselines
- Customer guidance for optimal system usage
Even if service plans are not always purchased at sale, SunHeat’s post-install relationship supports repeat business and referrals.
Competitive differentiation through technical process quality
SunHeat’s product is not only the hardware—it is the installation process quality. Customers often struggle to evaluate installers because they cannot easily assess internal workmanship until problems appear. SunHeat counters that opacity with measurable deliverables:
- Transparent sizing: customers understand why the recommended package matches usage.
- Documented commissioning/testing: customers receive proof that the system was commissioned properly.
- Consistent workmanship: standardised installation steps reduce leak probability and operational failure risk.
- Supplier performance management: SunHeat tracks component arrival timelines to prevent long installation delays that can cause customer dissatisfaction.
Service promise and customer experience
SunHeat’s service promise is structured around clarity at each stage:
- Quote stage: clear package explanation and expected usage match
- Scheduling stage: realistic installation timelines based on lead times
- Installation stage: disciplined roof and plumbing execution
- Commissioning stage: structured testing and handover guidance
- Post-install stage: support availability and service plan options
This customer experience reduces the gap between “sales promise” and “system reality,” which is the core quality perception risk in this market.
Market Analysis (target market, competition, market size)
Target market in Gauteng
SunHeat targets customers who experience both a cost incentive for solar hot water and enough roof/plumbing readiness to implement solar solutions reliably. The plan focuses on Gauteng because of its dense property distribution, high household electricity usage, and the ability to coordinate deliveries and service visits.
The core customer segments are:
-
Homeowners (middle-income households)
- Typically 25–60 years old
- Household incomes commonly ZAR 25,000–ZAR 80,000 per month
- Decision drivers include electricity cost increases, desire for durable utility savings, and preference for correctly installed systems.
-
Small landlords
- Value tenant satisfaction and hot-water reliability
- Often have multi-tenant usage patterns that benefit from correct system sizing.
-
Churches and community facilities
- Consistent hot-water usage patterns
- Need reliable systems for scheduled events and day-to-day operations.
Customer pain points and buying criteria
Customers do not buy solar water heating purely because it is “green.” They buy it because it reduces operating costs and improves hot-water availability. The central buying barriers in this region are:
- Fear of underperformance: customers worry a system will not deliver adequate hot water in real conditions.
- Fear of poor installation: roof mounting errors, incorrect plumbing integration, and lack of commissioning/testing create early failures.
- Confusion about sizing: customers struggle to understand why one installer recommends one package versus another.
SunHeat addresses these barriers through clear sizing logic, clean workmanship, and documented commissioning.
Market demand drivers
Gauteng electricity cost dynamics, persistent hot-water usage needs, and increased consumer awareness of renewable technologies continue to stimulate demand. Adoption remains uneven, but the market has enough density to support a scaled installer model as long as customer trust is earned.
Demand is further supported by:
- Local search behaviour (customers look up “solar geysers” and “solar water heating installation” in Gauteng),
- Referral cycles (plumbers, property managers, and roofing contractors refer customers),
- Social proof content (before/after installs and commissioning documentation).
Competitive landscape
Competition comes from a mix of established solar installation companies and smaller local installers, including combinations of hardware or plumbing installers that provide solar solutions. Competitive pressure is significant on first-cost pricing, which can compress margins for less disciplined operators.
Examples of key competitor presence include:
- Solar Geysers Johannesburg
- Propel Solar
- Local hardware-installer combinations
SunHeat’s differentiation strategy is designed to neutralise the primary competitive weakness of “price-only” installers. While SunHeat must be price-competitive, it wins by making quality visible and measurable:
- Transparent system sizing,
- Clean workmanship standards,
- Documented commissioning/testing,
- Strong scheduling reliability.
Market sizing logic for the business plan
The market opportunity is defined practically: SunHeat aims at feasible solar installs within Gauteng where the customer segments have:
- Roof access and structural suitability,
- Hot-water usage that justifies solar thermal installation,
- Sufficient budget capacity for credible system packages,
- Willingness to choose a reliable installer.
The business plan estimates a practical serviceable customer base of 120,000 potential properties and small hot-water users across Gauteng where solar solutions are feasible over a multi-year cycle. SunHeat’s early-year capture focuses on converting a small portion through referrals, targeted lead capture, and installer credibility.
SunHeat does not attempt to capture all possible demand in Year 1; instead, it builds conversion discipline by tracking each campaign’s lead-to-close rate. This keeps marketing spend efficient and reduces cash-flow risk during scaling.
Positioning strategy and why it works
SunHeat positions as a quality-first installer in a market that often sells with unclear technical justification. The positioning supports:
- Higher trust conversion among customers who compare multiple quotes,
- Lower churn risk due to fewer early performance failures,
- Stronger referral likelihood because customers can verify workmanship outcomes.
Market size versus capacity
SunHeat’s projected financial performance implies that the business can scale installations over time while holding gross margin at 62.0%. This scaling requires consistent capacity planning:
- Lead handling must feed installation scheduling,
- Procurement must supply components without delays that reduce installation throughput,
- Installer teams must complete jobs with quality and testing discipline.
The plan’s operational focus therefore aligns to market needs: demand is not the only constraint—delivery capacity is a key factor.
Regulatory and risk considerations
The solar water heating environment in South Africa is not purely commercial; safe roof installation, electrical/control integration standards, and plumbing integrity matter. SunHeat addresses safety risk through:
- A named Health, Safety & Compliance coordinator (see management section),
- Documented safe roof work practices,
- Quality checks and commissioning testing.
This reduces risk of customer disputes, rework, and safety incidents that can harm brand trust.
Marketing & Sales Plan
Marketing objectives and success metrics
SunHeat’s marketing and sales plan is designed around predictable lead generation and conversion, not just brand visibility. The core objectives are:
- Generate qualified leads in Johannesburg and surrounding Gauteng areas,
- Convert leads through credibility, transparent sizing, and fast scheduling,
- Protect customer experience via documented commissioning/testing and consistent handover,
- Maintain marketing spend efficiency by tracking lead sources and close rates.
Success metrics include:
- Lead volume by channel (Google Business Profile/local SEO, Google Search and Map campaigns, WhatsApp inbound)
- Lead-to-site-visit scheduling speed
- Quote conversion rate
- Average selling price mix across Packages A, B, and C
- Referral rate from plumbers, roofing contractors, and property managers
- Post-install service plan uptake rate (where applicable)
Target customer messaging
SunHeat’s messaging aligns to the decision drivers of homeowners and facility managers:
- Cost savings and reliability: solar hot water should be dependable.
- Proper sizing and transparency: customers should understand why the system fits their usage.
- Documented commissioning: the system should work from day one.
SunHeat avoids “overpromising” by centering its communications on what it can control: sizing discipline, workmanship quality, and commissioning testing.
Lead generation channels
SunHeat uses a multi-channel approach designed to build demand capture and trust:
-
Local SEO website
- Content targets installation-intent keywords for Gauteng.
- Each page supports lead capture by explaining process steps and package selection logic.
-
Google Business Profile + local SEO
- Improves visibility in local map results.
- Supports trust via reviews and proof of installs.
-
Google Search and Map campaigns
- Captures high-intent searchers.
- Drives calls and WhatsApp clicks from customers actively researching installers.
-
WhatsApp lead handling
- Enables fast response and scheduling.
- Quotes can be supported by initial info capture and prompt site visitation scheduling.
-
Referral partnerships
- Plumbers, roofing contractors, and small property managers can refer customers.
- These channels reduce conversion friction because referred customers already trust the recommending partner.
-
Social proof content
- Facebook and Instagram proof posts (before/after installs, system checks, customer feedback).
- Demonstrates workmanship and commissioning/testing outputs.
-
Estate signage and door-to-door
- Targeted approach in high-density homeowner areas.
- Works best when paired with strong local SEO and Google Business Profile visibility to validate credibility.
Sales process and conversion workflow
SunHeat’s sales workflow is built to reduce friction and increase conversion speed:
- Lead capture
- Incoming WhatsApp or web lead triggers an intake step.
- Qualification
- Capture occupancy size and hot-water usage patterns (home type, household size, usage times).
- Site visit scheduling
- Schedule a site visit where feasible soon after initial contact.
- Sizing recommendation and quote
- Recommend the appropriate package based on transparent sizing logic.
- Customer decision support
- Explain installation process, commissioning/testing steps, expected outcomes, and aftercare.
- Booking and deposit
- Collect a 30% deposit on booking to secure the schedule and protect working capital.
- Installation, testing and commissioning
- Complete installation with internal checklists and commissioning/testing documentation.
- Final payment and handover
- Collect the remaining 70% at installation completion after testing and commissioning handover.
- Service plan offer
- Provide optional annual service plan information at or after handover.
This end-to-end process is critical for both customer satisfaction and financial performance because it reduces rework risk and smooths cash flow.
Pricing strategy and package mix management
SunHeat’s pricing strategy is structured around package segmentation. While individual pricing is set by system type and hot-water demand, the business holds gross margin discipline at 62.0% across the forecast. Practically, this means:
- Supplier pricing and installation consumables must remain controlled,
- The installation team must execute efficiently without cutting essential testing steps,
- Procurement lead times must be managed to avoid rushed substitutions that could reduce margin or quality.
To maintain margin, SunHeat will manage package mix actively. Early ramp-up tends to use Packages A and B more heavily due to affordability fit, while scaling includes stronger targeting of Package C as credibility and proof increase.
Budget alignment with financial model
The financial model indicates Year 1 marketing and sales expense of R240,000, with growth across the forecast period. Marketing spend is therefore not treated as a discretionary cost; it is linked to lead acquisition and conversion.
SunHeat will allocate marketing budget within categories that map to expected lead generation outcomes:
- Paid search and map campaigns
- Website maintenance and content updates
- Brochures and printed collateral for trust-building
- Social proof content production
- Lead capture optimisation and messaging improvements
If performance is weak in a channel (e.g., low conversion rate), SunHeat reallocates spend to higher-converting channels rather than continuing spend that does not produce installation bookings.
Customer retention and service plan strategy
Even though the primary revenue driver is installation, SunHeat plans to create long-term customer value by:
- Offering service plans that maintain performance reliability,
- Using service interactions to strengthen referrals,
- Maintaining a post-install follow-up schedule to reduce early-life operational failures and customer dissatisfaction.
Retention impacts growth indirectly: satisfied customers refer, and referrals reduce customer acquisition cost compared to purely paid lead capture.
Operations Plan
Delivery model: from design to commissioning
SunHeat’s operational plan translates the customer promise into repeatable processes. Solar water heating installation involves both construction and mechanical integration, so operations must manage safety, quality control, and timeline discipline simultaneously.
The operational delivery model is structured around the job lifecycle:
- Inbound lead intake
- Site assessment
- System sizing and design confirmation
- Procurement and scheduling
- Installation execution
- Commissioning/testing
- Handover and documentation
- Service planning (optional)
Quality is treated as a process, not a single inspection. Internal checklists occur at multiple points to ensure:
- Correct roof mounting alignment and sealing,
- Correct plumbing integration without leak risks,
- Correct controller setup and temperature operation,
- Commissioning/testing evidence provided to customers.
Procurement and supply chain management
SunHeat must ensure component availability to protect installation schedules. The Operations & Procurement role (Themba Mthembu) is responsible for supplier performance, lead times, stock handling, and job scheduling.
Operational safeguards include:
- Standard supplier lists by component type,
- Lead time monitoring and buffer planning,
- Pre-install procurement verification to reduce on-site shortages,
- Workshop pre-assembly checks (coordinated by Workshop Lead).
These practices reduce delays that would otherwise reduce revenue opportunities and strain customer experience.
Installation workflow and workmanship standards
Installation quality is determined by roof mounting integrity, plumbing integration, and correct system configuration. SunHeat’s installation workflow includes:
- Roof readiness check
- Confirm roof suitability for mounting
- Plan mounting positions and confirm safe access
- Mounting and collector installation
- Ensure correct alignment and secure mounting
- Plumbing integration
- Install tank connections, valves, and necessary components
- Verify plumbing integrity and flow paths
- Controller configuration
- Configure system controllers according to package specification
- System testing and commissioning
- Run system checks and record results
- Customer handover
- Provide operating instructions and commissioning summary
Commissioning testing is the key step that protects the customer from “install-only” outcomes. SunHeat builds commissioning documentation into its standard deliverable.
Health, safety, and compliance operations
Solar installations involve roof work and plumbing integration; safety risk must be managed through training, safe work practices, and compliance documentation. SunHeat’s named SHEQ coordinator (Mandla Nkosi) ensures safe roof work practices and compliance documentation.
Operational safety includes:
- Safe roof access protocols
- Use of appropriate PPE
- Clear job risk assessment steps prior to roof work
- Incident prevention discipline
- Documentation of compliance and safety checks where relevant
This reduces both operational risk and brand reputation risk.
Scheduling and capacity planning
Capacity planning is essential to hit installation growth targets in the financial projections. SunHeat’s approach uses:
- Lead intake conversion discipline to prevent overcommitting,
- A job scheduling cadence that matches procurement lead times,
- Efficient installer task allocation to reduce idle time between jobs,
- Workshop pre-assembly to reduce on-site duration where safe and appropriate.
Operational KPIs:
- Average days from lead intake to installation completion
- Average job completion cycle time
- Percentage of jobs requiring rework (target: minimise through process checks)
- Customer satisfaction indicators based on feedback and referrals
Customer onboarding and aftercare
After sales follow-up impacts conversion and service revenue potential. SunHeat’s Sales & Client Success role (Sipho Dlamini) ensures:
- Customers receive clear scheduling communication,
- Deposits and payments follow expected structure,
- Customer onboarding includes expectations management around installation timelines,
- Aftercare includes service plan offers and support guidance.
The business uses a customer payment structure designed for cash-flow integrity:
- 30% deposit on booking,
- 70% collected at installation completion after testing and commissioning handover.
This structure supports working capital continuity during ramp-up.
Asset and equipment readiness
SunHeat’s startup includes tools, installation equipment, and test instruments. These assets support installation quality and commissioning testing capacity. It also includes vehicle deposit and setup for the used bakkie to support jobsite travel and component transport.
Equipment readiness is maintained through:
- Regular tool calibration and inspection (where relevant),
- Replacement and maintenance cycles planned within operating costs categories,
- Workshop organisation to enable fast job preparation.
Depreciation and capex assumptions in the plan
The financial model includes depreciation of R80,000 each year in all forecast years and includes capex outflow of -R400,000 in Year 1, with subsequent Years 2–5 capex at -R0. This aligns with the initial investment need concentrated at startup rather than recurring capex needs.
Operationally, this means:
- Equipment purchasing is primarily front-loaded,
- Replacement and consumables are managed within other operating costs and COGS categories.
Cost discipline and overhead management
Operational costs must scale with revenue without eroding margin. The financial model includes:
- Salaries and wages, rent and utilities, insurance, administration, and other operating costs.
SunHeat’s operational policy is to manage overhead through:
- Hiring aligned to capacity needs,
- Using workshop and pre-assembly to reduce installation time,
- Controlling marketing efficiency to avoid unnecessary spend increases.

Note on line item mapping: The model consolidates several operating expense categories under “Total OpEx” and includes “Rent and utilities” within that. The tabular “Other Expenses” line reflects the remaining operating cost components necessary to reconcile to the model’s Total OpEx for each year.
Projected Cash Flow (5 years)
The plan includes a full projected cash flow structure per the required category headings. The authoritative model provides key totals. Where the model lists totals rather than sub-lines, the sub-lines are presented in a way that reconciles to “Net Cash Flow” and “Closing Cash” exactly.

This cash flow output is consistent with:
- Operating CF: R983,041 (Year 1), R1,921,642 (Year 2), R2,787,209 (Year 3), R3,905,790 (Year 4), R5,346,151 (Year 5)
- Capex (outflow): -R400,000 in Year 1; -R0 thereafter
- Financing CF: R600,000 in Year 1; -R100,000 in Years 2–5
- Net Cash Flow: equals Operating CF + Capex + Financing CF as per the model totals
- Closing Cash: shown above exactly.
Projected Balance Sheet (5 years)
The financial model’s cash flows and P&L are provided; it includes the cash balance trajectory. The detailed balance sheet line items are not provided in the model block beyond the structure requirement. To remain consistent with the authoritative model data and avoid inventing figures, the balance sheet is presented using the model-consistent cash movement and recognising that other line items are not explicitly defined in the supplied model. Accordingly, totals remain coherent only for the cash component.

Important modelling note: This balance sheet representation strictly avoids adding invented values for receivables, inventory, liabilities, and PP&E not present in the authoritative block. Cash is fully consistent with the model’s closing cash.
Year 1 / Year 2 / Year 3 summary table (as required)
| Metric | Year 1 | Year 2 | Year 3 |
|---|---|---|---|
| Revenue | R6,864,000 | R8,669,232 | R10,949,240 |
| Gross Profit | R4,255,680 | R5,374,924 | R6,788,529 |

| Closing Cash | R1,183,041 | R3,004,684 | R5,691,893 |
Financial interpretation for investors
- The model shows strong gross profit generation due to stable gross margin at 62.0%.
- EBITDA and net income scale as revenue grows, supporting increasing profitability from Year 1 through Year 5.
- The DSCR values increase over time (as per model), suggesting stronger debt service capacity in later years:
- Year 1 DSCR: 11.38
- Year 2 DSCR: 18.51
- Year 3 DSCR: 28.96
- Year 4 DSCR: 44.34
- Year 5 DSCR: 67.16
This indicates the business can comfortably service interest and principal under the model’s financing assumptions while continuing to generate cash.
Funding Request (amount, use of funds — from the model)
Funding amount requested
SunHeat Solar Water Solutions (Pty) Ltd requests R700,000 in total funding.
Funding structure from the model:
- Equity capital: R200,000
- Debt principal: R500,000
- Total funding: R700,000
- Debt terms: 12.5% over 5 years
Use of funds (exact allocations from the model)
The requested R700,000 will be deployed as follows:
- Tools, installation equipment, and test instruments: R180,000
- Vehicle deposit and setup (used bakkie): R120,000
- Office fit-out, signage, and branding: R45,000
- Registration, legal, and compliance setup (CIPC, tax, VAT, admin): R25,000
- Marketing launch budget (web + initial leads + brochures): R30,000
- Working capital reserve (cash-on-hand bridge): R200,000
These uses align with the operational needs described in the operations plan—ensuring installation readiness, safety and commissioning capability, and sufficient launch liquidity while sales ramp-up occurs.
Cash flow protection logic
The working capital reserve is crucial in an installation business where cash timing can vary between deposit collection, component delivery, installation completion, and final handover. With SunHeat’s customer payment structure (30% deposit, 70% at completion after commissioning/testing), liquidity is improved, but a startup bridge remains essential to avoid schedule disruption.
Expected outcome of funding
The funding enables SunHeat to:
- Begin operations with capable tools and testing instruments,
- Maintain a reliable transport capability via the used bakkie setup,
- Launch marketing efforts to generate initial leads,
- Cover compliance and registration requirements,
- Maintain a cash buffer to protect installation scheduling during early growth.
Long-term financing rationale
The business is not financing capex in Years 2–5 according to the model (capex is -R0). Therefore, the funding request supports the front-loaded readiness and early working capital needs while letting the operating model generate scalable operating cash flow and growing profitability.
