Solar Tax Incentives SA: What Can You Claim?

The South African government introduced solar tax incentives to drive private investment in renewable energy amid the electricity crisis. These incentives allow both individuals and businesses to recover a portion of their solar installation costs through SARS — effectively reducing the real cost of going solar. This guide explains exactly what's available, who qualifies, and how to claim.

The Individual Solar Tax Rebate

Announced in the 2023 Budget Speech by Finance Minister Enoch Godongwana, the individual solar rebate allows qualifying taxpayers to claim back 25% of the cost of qualifying solar panels, up to a maximum rebate of R15,000.

Key Details

• Rebate rate: 25% of the cost of qualifying solar photovoltaic panels
• Maximum rebate: R15,000 per taxpayer
• This means: You need to spend at least R60,000 on qualifying panels to reach the maximum rebate
• What qualifies: New, unused solar PV panels with a minimum capacity of 275W per panel
• What does NOT qualify: Inverters, batteries, installation labour, wiring, mounting structures
• Must be used at your primary residence: Investment property panels may not qualify
• First use requirement: The panels must be brought into use for the first time by the taxpayer during the qualifying period

Worked Example: Individual Rebate Calculation

To reach the maximum R15,000 rebate, you'd need R60,000 worth of qualifying solar panels. A larger array (15+ panels at current prices) would get you there.

How to Claim on Your Tax Return

1. Obtain a compliant tax invoice from your solar installer showing: panel brand, quantity, wattage per panel, and the purchase price of panels separately itemised from labour and other components.
2. Ensure a Certificate of Compliance (CoC) was issued — SARS may require proof of compliant installation.
3. File your ITR12 (individual income tax return) for the tax year in which the panels were installed and brought into use.
4. Complete the relevant rebate section of the return — your tax practitioner or SARS eFiling will guide you to the correct field.
5. Keep all documentation for a minimum of 5 years in case of SARS audit.

Section 12B Business Solar Deduction

For businesses (sole proprietors, companies, trusts), the Section 12B allowance allows accelerated depreciation of qualifying renewable energy assets.

• Standard 12B: 50/30/20 — 50% in year 1, 30% in year 2, 20% in year 3
• Enhanced 12B (systems under 1MW): 100% deduction in year 1 — full cost written off against taxable income in the year of installation
• What qualifies: Solar panels, inverters, batteries, and installation costs for systems used in the production of income
• Cannot be used for personal residences under this section (that's the individual rebate above)
• Solar for business premises, rental properties, or commercial use qualifies

Business Deduction Example

Important Limitations and Requirements

• The individual rebate is a rebate against tax owed — if your total tax liability is less than R15,000, you can only claim up to your tax liability (you don't get a refund beyond what you paid)
• Panels must be new — secondhand panels do not qualify
• The installation must be at your primary residence for the individual rebate
• SARS can request proof of installation and professional CoC
• The rebate period and amounts may be extended or amended in future budget speeches — always confirm current rules with SARS

Other Incentives to Know About

• Eskom Solar Water Heater Rebate: Eskom has offered rebates on solar geysers in past years. Check current availability at eskom.co.za — amounts and availability change based on programme funding.
• Municipal feed-in tariffs: Some municipalities (Cape Town, Ekurhuleni, Stellenbosch) allow grid-tied solar customers to sell excess electricity back at a per-kWh rate. This is a financial benefit rather than a tax incentive. Enquire with your municipality.
• Green finance products: Some SA banks offer preferential interest rates on loans for green energy projects — ask your bank about "green bond" financing for solar.
