Why a 15 kW Solar System system works well in Limpopo
Limpopo enjoys high irradiance of 1,870 kWh/kWp with intense sunshine. Polokwane is growing rapidly — solar adoption is accelerating as Eskom tariffs increase.
For a 15 kW Solar System system, Limpopo's 1,870 kWh/kWp/year irradiance means annual output of 22,440 kWh. At the province's average residential tariff of R2.76/kWh, that generation is worth R3,100–R4,400 per month. With electricity tariffs rising ~10% per year, each year of delay costs you more in both higher bills and lower government tax rebate eligibility.
The 15 kW Solar System system is ideal for Commercial or large estate, with monthly electricity bills in the R8,000+ range. It generates enough power for daytime use in most Limpopo homes, and pairs well with a 5 kWh battery for load-shedding protection.
