How much can I expect to save on electricity bills?

Save money on your electricity bills thanks to your solar panels

Solar power could reduce your electricity costs 59%. This figure is calculated by comparing what the average household would pay per year on the Energy Price Guarantee (£1154) - to what they would pay with a 4kW solar system, assuming they use 40% of their generation (£544) and export 60% on a £0.055 rate through the Smart Export Guarantee (£132). With some changes in electricity consumption patterns such as setting up timers for appliances like dishwashers/washing machines, a household could easily increase their own consumption to 50% leading to 68% savings off an annual bill.

Optimal production is during the summer when systems generate the most electricity due to the extended hours of daylight and clearer days. In winter, the solar cells produce less. The solar plant will produce electricity for several decades. In the meantime, the price of electricity is rising, both due to inflation and due to increased taxes and investments in the electricity network, as well in security from foreign supplies of energy. This means that consuming solar electricity becomes more attractive compared to electricity you buy from the grid. Solar cells are good for the environment and good for your wallet. It's that simple.
