Proper installation of solar panels is necessary to ensure that those can work with maximum efficiency. As the day progresses, the Sun is going to cast light on your roof from different angles. Your solar panels should thus be installed accordingly, so as to ensure maximum utilization of available energy. Besides, regular maintenance of the solar panels will also keep those working properly. Here are some pointers that should help you with that:

Install panels only on roof: Ideally, you should always install solar panels on the roof. If you install those on the walls or around windows, those will at most receive solar energy for half a day. However, if you install the panels on the roof, those will receive sunlight for a much longer duration.

Install panels on a flat surface: If possible, install the panels on a flat surface placed parallel to the roof. That way, the cells will remain exposed to sunlight as the sun shifts across the sky. Avoid installing the cells on a surface that is tilted at an angle. That way, a significant portion of the cells will lose contact with sunlight as the day progresses.

Keep the covers of the cells clean: Cells left on the roof will eventually get dirty. Be sure to clean the top surface of the cells periodically, to ensure that dust and dirt do not cover the surfaces of the cells and interfere with energy production.

Have the wiring serviced periodically: It is good to have the wires connecting the cells with the batteries checked periodically. That will ensure that there is no corrosion in the wires, which can significantly affect energy production.

These simple precautions should help you get the most out of your solar photovoltaic (PV) panels. Keep your solar panels in top notch condition, and these will provide you with an abundant supply of energy, for years to come.
