Can I add reflectors/concentrators/trackers to the solar array installation to increase the power they generate?
Solar cells will produce more electricity if the incident light is concentrated by using mirrors or reflectors. Concentrating the light through optics and reflectors can be an economical way to improve the power capacity of a system. Solar trackers are devices operate by changing the angle of the solar panels to follow the sun as it moves across the sky. With the solar panels facing the sun for most of the day, the power generated is larger than the power generated without the tracker installed. Trackers come in a variety of options depending on the different number of rotational axis used to track the sun. The cost of the tracker often is not worth the additional power increase they provide. It is important to be aware of the concentrator and tracking options for solar installations, but the cost often does not justify their installation. It is a good idea to ask about them when consulting with a company for a roof-top solar installation.
