Why South Africans are switching to solar
Eskom tariffs up 600% since 2010
Eskom tariffs have risen from R0.43/kWh in 2010 to R2.76/kWh in 2026 — a 642% increase. NERSA's approved multi-year price determination projects another 30–40% by 2028. Solar locks in your electricity cost today.
Load-shedding isn't going away
Stage 6 load-shedding costs the SA economy R4 billion per day. A properly sized solar + battery system keeps your home or business running through any stage, any time of day.
Best solar resource in the world
South Africa receives 4.5–6.5 peak sun hours per day — significantly better than Germany, the UK, or most of Europe. The Northern Cape exceeds 2,000 kWh/kWp annually. Even cloudy coastal cities outperform most solar markets globally.

How we calculate your savings
PVGIS satellite data + your real local tariff
Every FlowLeads quote uses PVGIS v5.2 irradiance data from the EU Joint Research Centre — the same dataset used by South Africa's NERSA. We combine it with your municipality's published block tariff to calculate actual savings, not national averages.
