Why a 5 kW Solar System system works well in Northern Cape
The Northern Cape has the best solar irradiance in South Africa — Upington averages over 2,050 kWh/kWp. Despite lower tariffs, the exceptional sun hours make solar highly viable.
For a 5 kW Solar System system, Northern Cape's 1,980 kWh/kWp/year irradiance means annual output of 7,920 kWh. At the province's average residential tariff of R2.76/kWh, that generation is worth R1,100–R1,550 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 5 kW Solar System system is ideal for 3–4 bedroom family home, with monthly electricity bills in the R1,500 – R3,000 range. It generates enough power for daytime use in most Northern Cape homes, and pairs well with a 5 kWh battery for load-shedding protection.
