Can you finance solar with your home loan? (2026)

By Erazon Solar, Pretoria · Updated

Yes. The big South African banks let homeowners pay for solar through their bond, either by drawing back money already paid in (a re-advance or access bond) or by increasing the loan (a further loan). Because the loan is secured on your house, the interest rate is your home loan rate, which is usually much lower than a personal loan (Engineering News, quoting FNB). This is how most of our clients who finance their systems pay for them.

What does each bank offer for solar?

  • Standard Bank: a re-advance up to the difference between your registered bond and what you still owe, or a further loan if there is equity in the property (LookSee).
  • Nedbank: use NedRevolve, a readvance or a further loan, or a new home loan of up to 110% with the extra 10% for the energy solution (Nedbank).
  • FNB: a solar-linked home loan that can fund an installation up to 15% above the property's value. On a R1 million home with a full bond, that is up to R150,000 (Engineering News).
  • Absa: a further advance based on your property's current value, and for applications approved from 22 August 2026 to 31 July 2027 Absa contributes up to R30,000 towards the further bond registration costs if you qualify (Absa).

Bank offers change. Check the current terms with your bank before you apply. We are not a bank or a financial adviser, and this is not financial advice.

What is the mistake to avoid when financing solar on a bond?

Paying it off over 20 years. A battery or inverter will not last as long as your bond. FNB's Kival Singh has suggested structuring solar finance so it is paid back within six to seven years (Daily Maverick). If your bank adds the amount to your bond, pay a bit extra each month so the solar portion is cleared in that time.

How does the monthly cost compare with the electricity you save?

That depends on your bill. Tshwane households on the top tariff block pay up to R5.12 a unit including VAT (EnergyBee), so for a home with a big bill, the saving can cover a large part of the extra bond instalment. Send us your last bill and we will work out the saving for your house, then you can compare it with the instalment your bank quotes.

What do I need from the installer to apply?

Banks generally want a written quote with the equipment list and total price before they release the money. Our quotes list every component, the installed price and what is included, so you can send it straight to the bank. Our package prices are published on the solar system prices page, so you can start the conversation with your bank before we even visit.

Common questions

Can I add solar to my home loan?

Usually yes, through a re-advance, an access bond or a further loan, depending on your bank and how much equity you have in the property.

Is it better to finance solar on a bond or a personal loan?

A bond is normally much cheaper because it is secured on your home. Just keep the repayment period short so you are not still paying for the system after its equipment warranties end.

Does Erazon Solar offer its own solar finance?

Not at the moment. Clients who finance their systems use their home loan. We supply the detailed quote the bank needs.

How long does a further loan take?

A re-advance or access bond is usually quick. A further loan needs a valuation and bond registration, so allow a few weeks.
