Solar collector
A solar collector is a device that collects and/or concentrates solar radiation from the Sun.These devices are primarily used for active solar heating and allow for the heating of water for personal use. These collectors are generally mounted on the roof and must be very sturdy as they are exposed to a variety of different weather conditions.. The use of these solar collectors provides …
