You could be losing up to 70% of the energy that your panels produce based on figures produced by PassivSystems, the largest solar metering company in the UK. Solar panels produce the most electricity during the day when a lot of people are at work. In the summer when they are at their peak performance, many families spend a lot of time outside and their energy usage is a lot lower. By storing the excess electricity that you generate during the day into a battery, you are able to use it in the evening when the sun has gone down and your energy consumption is usually at its highest. Reducing the amount of power you need to draw from the grid, further reducing your energy bills.
Whilst most people install batteries to store the excess energy produced by their solar PV panels, there are a number of other benefits. By choosing to move to a differential rate with your energy supplier (formerly known as economy 7) you can charge your batteries during the night when you will pay up to 50% less for your electricity.
Homeowners are now able to generate more income by allowing the energy companies to use your battery to store electricity to balance the grid. You would basically become an energy trader. This is becoming more popular as the use of blockchain technology evolves.
