I’m often asked the question: Is solar power cheaper than electricity? The answer is a resounding yes. In South Africa, the cost of traditional electricity from the grid continues to rise, making solar power a more cost-effective and sustainable option for many households and businesses. With advancements in technology and government incentives for renewable energy, the upfront cost of installing solar panels has decreased significantly in recent years.
Here’s why investing in solar energy is the smartest financial move you can make.
4 Top Reasons Why Solar Power is Cheaper than Electricity: Solar vs. Eskom
1. Fixed Solar Costs vs. Rising Electricity Bills
Grid electricity prices are unpredictable and consistently rising due to inflation and infrastructure maintenance. We’re not even mentioning the loss of productivity during load shedding or the increased costs of using air-polluting fuel-driven generators.
With solar power, you make a one-time investment in a system that generates free energy for decades. This shields you from the financial burden of Eskom’s familiar rising tariffs.
2. Energy Independence and Reliability
Solar systems, particularly those with battery storage, allow you to generate and store power. This ensures an uninterrupted energy supply even during load shedding, something the grid simply can’t guarantee.
3. Government Incentives and Tax Benefits
South Africa provides tax credits and rebates for solar installations, lowering upfront costs for business owners.
- Businesses can deduct up to 125% of eligible costs for solar PV, wind, and hydro systems (FAQ here).
Side Note: Landlords with commercial property can sell excess power to the City of Cape Town and solar power to the tenant.

4. Costs: Solar Power vs. Grid Electricity in South Africa
The great news when comparing solar power vs. grid electricity is that you do not have to wait for the government to do maintenance. You call us, we come, we service, and we maintain. It certainly eliminates the frustration of months of blackouts.
Cost Comparison Over 25 Years:
- Solar Power: R70,000–R200,000 (once-off investment + maintenance)
- Grid Electricity: Over R1,068,750 (ongoing payments and rising tariffs)
With an average payback period of 3-6 years, the savings on electricity expenses significantly outweigh the initial investment in solar.
