Solar panels
Solar panels can be used as your source of electrical energy. Aside from economy, it can also protect from fires and short circuits. Solar panels are placed on the roof facing the east to west in order to make sure that you will get enough solar energy. If you haven’t placed solar panels yet, make sure that your roof is designed with this provision. Pick a roofing material that will reflect radiant heat like a light-colored standing seam metal roof.
