Solar power has become increasingly less expensive to use in recent years, as a result, users find that they make substantial savings on their annual energy bills after adding an installation to their property. Surplus energy generated by systems can also be sold back to the National Grid, making profits for homeowners. An additional advantage is that including solar panels in a property can also increase the value of a home with many homebuyers on the lookout for greener and more energy-efficient options on the market.
