Question 1

How much does a solar system cost in South Africa?

Accepted Answer

A basic grid-tied system (no battery) for a medium home costs R80,000-R120,000. A system with battery backup (5kWh) costs R150,000-R250,000. A full off-grid system with enough battery for a whole house costs R300,000-R500,000+. Prices have dropped significantly since 2023.

Question 2

How long does solar take to pay for itself?

Accepted Answer

A grid-tied system (no battery) typically pays for itself in 4-6 years through electricity savings. A system with batteries takes 6-10 years. After that, your electricity is essentially free for the remaining 15-20 year lifespan of the panels.

Question 3

Can I claim solar on my tax?

Accepted Answer

Yes! For the 2025/2026 tax year, individuals can claim a 25% tax rebate on solar panels (not batteries or inverters) up to a maximum of R15,000 per person. This was introduced in 2023 to encourage solar adoption. The panels must be new and installed at your home.

Question 4

Do I need batteries or can I just use panels?

Accepted Answer

You can install panels without batteries (grid-tied). During the day your panels power your home and feed excess back to the grid (if your municipality allows). At night you use Eskom power. This is the cheapest option with the fastest payback, but you won't have backup during load shedding.

Question 5

How much electricity does a solar panel produce?

Accepted Answer

A standard 550W panel in South Africa produces about 2.2-2.8 kWh per day (depending on your location and roof direction). A typical home uses 20-30 kWh per day, so you'd need 8-12 panels to cover most of your daytime usage.

Question 6

Will solar panels damage my roof?

Accepted Answer

No, if installed correctly. Panels are mounted on rails that attach to your roof trusses. A good installer will waterproof all mounting points. Panels actually protect the roof tiles underneath from sun and rain damage. Always use a certified installer.
