A solar cell battery has a maximum power of 1 kW. The battery, when used in the United Kingdom, produces, on average, 10% of its maximum power. The battery costs £ 4000 and has a design life of 200 000 hours. The cells have no maintenance costs. What is the cost per kilowatt-hour of electricity produced by the battery of solar cells when used in the UK?
produces 0.1 kW of one hour for 200,000 hours so produces 20,000 kW 4000 / 20000 = £ 0.20 per kWh
