Why You Should Consider Investing in Rooftop Solar for Your House or Business

Rooftop solar (Solar PV panels and Solar Thermal collectors installed on the roofs of residential and commercial buildings) has proven in many countries to make a significant contribution to the total electricity supply network.

South Africa faces ongoing electricity supply challenges, and rooftop solar offers a practical, proven solution for both homes and businesses to reduce dependence on the grid, cut electricity costs, and contribute to a more sustainable energy future.

The Case for Solar PV

Solar photovoltaic (PV) panels convert sunlight directly into electricity. With South Africa’s exceptional solar resource — some of the highest irradiance levels globally — PV systems here perform significantly better than in most other countries where solar has already become mainstream.

Key benefits include:

• Reduced electricity bills — Generate your own power during peak daylight hours
• Protection from tariff increases — Eskom tariffs have risen well above inflation; solar locks in a low marginal cost of electricity
• Return on investment — Well-designed systems typically pay back their capital cost within 5–8 years, with a lifespan of 25+ years
• Load-shedding resilience — When paired with battery storage, solar keeps the lights on during outages

Solar Thermal for Hot Water

Solar thermal collectors heat water directly using the sun’s energy, replacing the electricity or gas your geyser would otherwise consume. Hot water heating accounts for a substantial share of a typical household’s electricity bill — making solar thermal one of the fastest-payback solar investments available.

Is Your Property Suitable?

Most houses and commercial buildings with a south-facing or west-facing roof can benefit from solar. A shading assessment and an energy audit help determine the right system size and the realistic savings you can expect.
