Commercial Solar ROI for SA Businesses
How South African businesses should frame solar ROI — daytime loads, tariffs, resilience and phased BESS.
For many SA SMEs, solar is both a cost and continuity project. Finance teams want IRR; operations wants the tills and cold chain alive at Stage 6.
ROI levers
- Align array size to weekday daytime kWh
- Model tariff correctly (TOU vs flat, demand charges where applicable)
- Phase batteries: start with critical circuits, expand storage later
- Include maintenance and inverter replacement reserves
Procurement tip
Commercial buyers should insist on clear scopes, staged battery options and compliance support. Solar News 24 helps you structure the brief before installer quotes land.
