Why a 5 kW Solar System system works well in Eastern Cape
The Eastern Cape offers good solar conditions with 1,775 kWh/kWp on average. Port Elizabeth (Gqeberha) and East London have historically had lower tariffs but rising rates improve solar ROI every year.
For a 5 kW Solar System system, Eastern Cape's 1,775 kWh/kWp/year irradiance means annual output of 7,100 kWh. At the province's average residential tariff of R2.76/kWh, that generation is worth R1,000–R1,400 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 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 Eastern Cape homes, and pairs well with a 5 kWh battery for load-shedding protection.
