Updated April 2026 • South Africa Finance Guide • 8 min read
Overview
Load shedding has made alternative power essential for South African homes and businesses. Solar systems have become the most popular solution, with payback periods of 4-6 years making them a sound financial investment.
Key Details
Basic UPS and battery (R5,000-15,000): Powers essentials (lights, Wi-Fi, phone charging) during load shedding for 3-6 hours. Cheapest entry point but limited capacity. Popular brands: Mecer, Gizzu, Ellies.
Important Considerations
3kW solar system with battery (R80,000-120,000): Powers a small to medium home including lights, fridge, TV, and small appliances. Covers most Stage 1-4 load shedding. Battery provides 4-8 hours backup.
Additional Information
5kW solar system with battery (R120,000-180,000): The sweet spot for average South African homes. Powers everything except high-draw appliances (geyser, pool pump, oven). Battery provides 6-10 hours backup. Covers all current load shedding stages.
Practical Tips
8-10kW off-grid system (R200,000-500,000+): Full household including geyser and pool pump. Can go completely off-grid from Eskom. Makes financial sense at current Eskom tariff increases of 15-20% annually.
More Information
Net metering allows selling excess solar production back to the municipality in some areas (Cape Town, Johannesburg, others). This can further reduce the payback period. FNB and Nedbank offer green home loans specifically for solar installations at competitive rates.
