Renewable Energy Business Plan Template

A complete business plan framework for solar installation companies and renewable energy service providers operating in the South African market.

1. Executive Summary

The Market: South Africa's energy crisis has created the fastest-growing solar installation market in sub-Saharan Africa. Eskom's annual tariff increases (averaging 15–18% per year) and ongoing load shedding have made solar economics undeniable. The question is no longer "should I go solar?" — it is "who do I trust to install it correctly?"

Project Economics Model (Reference Business: 6 installations/week, Month 8):

| Installation Type | Projects/Week | Avg Project Value | Weekly Revenue | | :--- | :---: | :--- | :--- | | Residential 10–15kW | 2 | R170,000 | R340,000 | | Residential 15–25kW | 1 | R260,000 | R260,000 | | Commercial 50–100kW | 0.5 (2/month) | R900,000 | R450,000 (avg/week) | | Weekly revenue total | | | R1,050,000 | | Monthly revenue (4.3 weeks) | | | ~R4.5M |

For a leaner startup (2 residential + 1 commercial per week from Month 6):

| Month | Installations | Revenue | COGS (72%) | Gross Profit | | :--- | :---: | :--- | :--- | :--- | | Month 3 | 6 total | R720,000 | R518,400 | R201,600 | | Month 6 | 12 total | R1,440,000 | R1,036,800 | R403,200 | | Month 8 | 16 total | R1,920,000 | R1,382,400 | R537,600 | | Month 12 | 20 total | R2,400,000 | R1,728,000 | R672,000 |

Plus O&M recurring revenue building from Month 6: R800–R2,500/site/month.

Total Startup Investment: R1,400,000 (accreditation R180k, initial inventory R650k, vehicles and tools R420k, office/warehouse R150k). Targeting breakeven in Month 6 at 12 installations/month.

Our Focus: [Define your primary service mix — residential vs commercial vs mixed.]

3. Market Analysis

The Eskom Tariff Trajectory

| Year | Approved Tariff Increase | Cumulative Increase (Base 2020) | Solar Payback Period | | :--- | :--- | :--- | :--- | | 2022 | 9.6% | — | 7–9 years | | 2023 | 18.65% | 30% above 2020 | 6–7 years | | 2024 | 12.74% | 46% above 2020 | 5–6 years | | 2025 (est.) | 12–15% | 65%+ above 2020 | 4–5 years | | 2026 (est.) | 10–13% | 85%+ above 2020 | 3.5–4.5 years |

Every tariff increase is a free sales pitch delivered by Eskom to your entire addressable market.

Load Shedding Economic Impact

• SA businesses lost an estimated R1.2B per day in productivity during Stage 4–6 load shedding.
• Commercial and industrial clients can calculate their own diesel/generator costs — solar ROI is often under 4 years versus diesel.
• Grid-tied SSEG systems with battery backup eliminate diesel costs entirely for most SMEs.

Market Demand Drivers

| Driver | Impact | Timeline | | :--- | :--- | :--- | | Eskom tariff increases (15%+/year) | Makes solar financially obvious | Ongoing | | Stage 4–8 load shedding | Creates urgency in buyer decision | Immediate | | Municipal SSEG programmes | Enables grid sell-back, improves ROI | Growing | | Government Section 12B tax incentive | 125% deduction on renewable energy assets | Business clients | | Property value uplift from solar | R80–R150k value add on residential property | Ongoing | | Carbon tax obligations (commercial) | Industrial clients seeking low-carbon credentials | Growing |

4. Customer Personas

| Persona | Profile | System Size | Budget | Decision Driver | Sales Cycle | | :--- | :--- | :--- | :--- | :--- | :--- | | Homeowner (middle-income) | R25k–R60k/month household income | 8–12kW + 10kWh battery | R120k–R175k | Load shedding frustration, long-term savings | 2–6 weeks | | Homeowner (affluent) | R80k+/month, security estate | 15–25kW + 20kWh battery | R220k–R350k | Energy independence, property value | 1–4 weeks | | Commercial Property Owner | Office park, retail strip, school | 50–200kW grid-tied | R700k–R2.5M | Electricity cost reduction, tenant retention | 6–16 weeks | | Industrial Client | Factory, cold storage, farm | 200kW–2MW | R3M+ | Diesel replacement, production continuity | 3–9 months | | Embedded Property Developer | New development, sectional title | Per-building design | Negotiated | SANS 10400-XA compliance, tenant attraction | 2–4 months |

Key Insight: Residential homeowners make emotional decisions (load shedding frustration) and move quickly. Commercial clients make financial decisions (ROI spreadsheets) and move slowly. Staff and pipeline accordingly.

5. Technology and Equipment

Panel Brands and Specifications

| Brand Tier | Example Brands | Watt-Peak Range | Cost per Wp | 25-Year Warranty? | | :--- | :--- | :--- | :--- | :--- | | Tier 1 (recommended) | Jinko, LONGi, Trina, Canadian Solar | 400–580Wp | R2.50–R3.80 | Yes | | Tier 2 | Risen, Astronergy | 400–550Wp | R2.00–R2.80 | Some | | Premium | SunPower, REC | 400–500Wp | R5.00–R8.00 | Yes |

Recommend Tier 1 only to clients. Cheaper panels generate warranty call-backs and reputational damage.

Inverter Types

| Inverter Type | Best Application | Brands | Price Range (5–10kW unit) | | :--- | :--- | :--- | :--- | | String inverter (grid-tied) | Commercial, simple rooftops | Solis, Huawei, SMA | R12,000–R35,000 | | Hybrid inverter (grid + battery) | Residential with battery | Sunsynk, Deye, Victron | R18,000–R55,000 | | Off-grid inverter / charger | Remote sites, off-grid | Victron, Axpert | R15,000–R40,000 | | Microinverter | Complex rooftops, shading | Enphase, AP Systems | R4,000–R8,000/panel |

Battery Storage

| Battery Type | Chemistry | Cycle Life | Cost per kWh | Best For | | :--- | :--- | :--- | :--- | :--- | | Lithium Iron Phosphate (LiFePO4) | LFP | 4,000–6,000 cycles | R3,500–R5,500 | All residential and commercial | | Lead-acid (GEL/AGM) | Lead | 500–1,200 cycles | R1,200–R2,000 | Budget off-grid, backup only | | Lithium NMC | NMC | 2,000–4,000 cycles | R3,000–R5,000 | High-energy-density applications |

Recommend LFP only. Lead-acid generates warranty issues and dissatisfied clients within 3 years.

6. System Sizing and Pricing Table

| System Size | Panels (400Wp) | Inverter | Battery | Component Cost | Labour | Retail Price | Gross Profit | | :--- | :---: | :--- | :--- | :--- | :--- | :--- | :--- | | 5kW (basic residential) | 13 | 5kW hybrid | 5kWh LFP | R55,000 | R12,000 | R85,000 | R18,000 (21%) | | 10kW (standard residential) | 25 | 10kW hybrid | 10kWh LFP | R105,000 | R18,000 | R160,000 | R37,000 (23%) | | 15kW (large residential) | 38 | 15kW hybrid | 15kWh LFP | R155,000 | R25,000 | R230,000 | R50,000 (22%) | | 30kW (small commercial) | 75 | 30kW string | 0 (grid-tied) | R200,000 | R45,000 | R320,000 | R75,000 (23%) | | 100kW (commercial) | 250 | 100kW string | Optional | R650,000 | R120,000 | R1,050,000 | R280,000 (27%) | | 250kW (industrial) | 625 | 250kW string | Optional | R1,550,000 | R280,000 | R2,500,000 | R670,000 (27%) |

Include SSEG registration fee (R8,000–R25,000) as a separate line item. It is a service, not a product — margin is 65%+.

7. Staffing Model

| Role | Monthly Cost | Qualifications Required | Notes | | :--- | :--- | :--- | :--- | | Project Manager | R40,000 | Engineering/project management | Manages pipeline, site supervision, client liaison | | Master Electrician (ECASA) | R35,000 | CoC, ECASA registered | Signs off all installations — mandatory | | Solar Technician / Installer (senior) | R22,000 | SAPVIA accredited | Leads installation crew | | Junior Installer (×2) | R15,000 each | On-the-job training | Panel mounting, cabling, basic wiring | | Sales / Business Development | R18,000 + 3% commission | Technical sales background | Lead qualification, site visits, proposals | | Admin / Finance | R10,000 | Bookkeeping preferred | Invoicing, SSEG documentation, supplier orders | | Total Monthly Payroll | R155,000 | | 7 people |

Scale: Add one installation crew (1 senior + 2 junior) per additional 4 residential systems per week capacity.

8. Project Pipeline and Sales Cycle

Lead-to-Install Timeline

| Stage | Residential | Commercial | | :--- | :--- | :--- | | Lead received | Day 0 | Day 0 | | Site assessment | Day 1–3 | Day 3–7 | | Proposal delivered | Day 3–5 | Day 7–14 | | Quote accepted | Day 5–21 | Day 14–60 | | 50% deposit received | Day 6–22 | Day 15–61 | | Equipment ordered | Day 7–23 | Day 16–62 | | Installation | Day 10–28 | Day 30–90 | | CoC issued | Day 11–30 | Day 31–92 | | SSEG application (if grid-tied) | Day 12–31 | Day 32–93 | | SSEG approved | Day 40–180 | Day 60–270 | | Final payment | Day 12–31 | Day 31–93 |

Deposit Structure

| Payment Stage | Residential % | Commercial % | | :--- | :--- | :--- | | Deposit on acceptance | 50% | 40% | | On equipment delivery to site | 30% | 35% | | On completion and CoC | 20% | 25% |

Cash Flow Note: Never order equipment without deposit. Equipment cost is 65–72% of project value — ordering on credit before deposit is a cash-flow trap that kills installation businesses.

9. O&M Recurring Revenue Model

Operations and Maintenance (O&M) contracts convert your install base into a recurring revenue stream. This is the model that makes solar companies defensible businesses, not just project contractors.

| Contract Tier | Site Size | Monthly Fee | Services Included | Margin | | :--- | :--- | :--- | :--- | :--- | | Basic (residential) | Up to 15kW | R800/month | Annual panel clean, system health check, remote monitoring | 60% | | Standard (small commercial) | 15–100kW | R1,500/month | Quarterly service, remote monitoring, priority response | 58% | | Premium (commercial/industrial) | 100kW+ | R2,500–R8,000/month | Monthly service, SLA response time 4 hours, reporting | 55% |

O&M Revenue Projection:

| Month | Installed Sites | Avg O&M Fee | Monthly O&M Revenue | | :--- | :---: | :--- | :--- | | Month 6 | 20 sites | R1,100 | R22,000 | | Month 12 | 50 sites | R1,200 | R60,000 | | Month 18 | 100 sites | R1,300 | R130,000 | | Month 24 | 180 sites | R1,400 | R252,000 |

By Month 24, O&M revenue alone covers your full monthly payroll.

10. Monthly Financial Model

This model is for a 2-person team with 1 installation crew at Month 6 and 3 crews by Month 12.

| Line Item | Month 3 | Month 6 | Month 12 | | :--- | :--- | :--- | :--- | | Residential installations (×) | 4 × R160k | 8 × R160k | 12 × R160k | | Commercial installations (×) | 1 × R900k | 2 × R900k | 3 × R1,100k | | SSEG and admin services | R24,000 | R56,000 | R90,000 | | O&M contracts | R8,000 | R42,000 | R120,000 | | Total revenue | R1,672,000 | R3,394,000 | R5,490,000 | | Equipment COGS (68% of install revenue) | -R1,105,920 | -R2,210,880 | -R3,475,200 | | O&M direct costs (40% of O&M) | -R3,200 | -R16,800 | -R48,000 | | Gross profit | R562,880 | R1,166,320 | R1,966,800 | | Payroll (7 staff) | -R155,000 | -R185,000 | -R270,000 | | Vehicle costs (fuel, maintenance) | -R25,000 | -R40,000 | -R65,000 | | Warehouse rent and utilities | -R18,000 | -R18,000 | -R25,000 | | Insurance (liability, vehicle, PI) | -R12,000 | -R12,000 | -R18,000 | | Marketing and lead generation | -R20,000 | -R25,000 | -R35,000 | | Total operating costs | R230,000 | R280,000 | R413,000 | | Net operating profit | R332,880 | R886,320 | R1,553,800 | | Loan repayment (R1.4M over 5 years) | -R28,000 | -R28,000 | -R28,000 | | Net profit after debt service | R304,880 | R858,320 | R1,525,800 |

Gross margin target: 28–35%. If you fall below 22%, re-examine equipment sourcing and installation labour costs.

11. Risk Assessment

| Risk | Likelihood | Impact | Mitigation | | :--- | :---: | :---: | :--- | | Municipality SSEG delays (3–9 months) | High | Medium | Set client expectations upfront; charge for SSEG admin separately; follow up weekly | | Import tariffs on Chinese panels | Medium | High | Maintain 60-day inventory buffer; diversify to 2 panel suppliers; pass tariff increases to clients | | Client payment default | Medium | High | 50% deposit before ordering; never hand over CoC before final payment | | Electrical accident on site | Low | Very High | ECASA-registered master electrician on every job; PPE policy; COID insurance | | Key installer departs | Medium | High | Cross-train; non-compete clauses; SAPVIA certify 2 senior installers | | Load shedding eases (demand reduction) | Low | High | O&M recurring revenue provides buffer; diversify into commercial and industrial | | Competitor price undercutting | High | Medium | Compete on quality, warranty, SAPVIA credentials — not price | | Inverter or panel recall / defect | Low | High | Only stock Tier 1 brands; maintain supplier warranty relationships |

Strategist's Note

SA's energy crisis is your best salesperson. Every Stage 4 load shedding announcement generates more qualified leads than any marketing campaign you could run. Your only job is to show up on time, install correctly, issue the CoC on the day, and get SSEG done without the client having to chase you.

The referral rate in solar is 40%+ when you execute well. Every residential installation in a security estate is a billboard to 200 neighbours. Ask every happy client for 3 referrals within 7 days of completion while the goodwill is highest.

Build your O&M base from Day 1. The solar business that wins long-term is the one with 500 O&M sites generating R700,000/month in recurring revenue while competitors scramble for the next project. That recurring base is also what makes your business fundable, sellable, and defensible against pricing competition.

Do not compromise on Tier 1 panels and LFP batteries to win price-sensitive clients. One roof leak from cheap mounting hardware or one battery fire from low-grade cells will cost more in insurance, legal fees, and reputational damage than the margin you saved.
