The upfront cost problem
A quality 5 kW solar system costs R90,000–R130,000 installed. For most South African households, that's not money sitting in a cheque account. The good news: you don't need to pay it all upfront.
Option 1: Personal / home improvement loan
Standard Bank, Nedbank, FNB, Absa, and Capitec all offer personal loans up to R300,000 that can be used for solar. Interest rates range from prime + 1% to prime + 8% depending on your credit profile. At current prime (11.75%), a R90,000 loan over 5 years costs approximately R2,000–R2,200/month — offset by R1,200–R1,800/month in electricity savings.
Net monthly cost: R200–R1,000/month, while your asset is growing in value.
Option 2: Bond top-up / home equity
If you have equity in your home, a bond top-up is typically the cheapest financing route. You extend your home loan at the bond rate (currently ~11.75%) rather than a personal loan rate. Bond rates are lower than personal loan rates, and the interest may be partially deductible if the property generates rental income.
Option 3: Rent-to-own
Solar rental companies (Solarize, SolarAfrica, and others) own the system and charge a monthly rental — typically R1,500–R3,500/month depending on system size. At the end of the rental period (5–10 years), you own the system outright. No upfront payment.
Caution: Read the fine print on escalation clauses. Some rental agreements escalate at 10% per year, making long-term cost very high.
Option 4: Power Purchase Agreement (PPA)
Under a PPA, the solar company owns and maintains the system forever — you simply pay per kWh generated, at a fixed rate below your municipal tariff. No upfront cost, no maintenance. The downside: you never own the system, and your savings are locked to the agreed kWh rate rather than the full tariff savings you'd get as an owner.
Option 5: SARS Section 12B + cash
If you're a taxpayer in the 36%+ bracket, the Section 12B deduction (125% of panel cost) effectively reduces your real system cost by R10,000–R20,000. This makes paying cash more attractive — see our SARS solar rebate guide.
