The economic factor of solar roofs is that they serve a double function. They are especially beneficial for homeowners who need a new roof and want to retain aesthetics and roof functionality. In many countries, there are still subsidies for local renewable energy production, which makes solar even more attractive. A solar roof can potentially cut the electricity bill of an efficient home down to near zero. Despite the high initial investment, solar roofs tend to be worth it. If you’re looking for a way to save the most on your electric bills, you’re probably better off going with a traditional solar panel installation. Bear in mind that a traditional roof does not bring your electricity costs down, nor earn the investment back.
