Alongside this, depending on how much solar energy is being generated, it is possible to sell or export unused electricity back to the National Grid. This will vary and depend on factors such as the time of year, the hours of sunlight during the day, and your electricity usage. At certain times of the year, it is highly likely that excess electricity will be produced and can be sold back to the grid.
Thanks to the STC scheme, generating your own electricity helps offset some of the solar panel installation costs and contributes to reducing your electricity bills. Over a period of 15 to 25 years solar panels are expected to have paid for themselves and will begin to make a small profit.
Like other renewable energies, solar power is entirely clean as it doesn’t release any harmful emissions or pollutants. In fact, solar power does the opposite and contributes massively to reducing CO2 emissions produced by fossil-fuel powered energies.
Unlike fossil fuels, solar power is also completely sustainable and abundant enough to last us for as long as the sun exists. According to scientists, the sun will continue shining for approximately 5 billion years, meaning we won’t run out of solar energy for as long as we occupy planet earth.
