Active Solar Systems

Active solar systems use solar collectors and a pump or a fan to distribute the sun’s energy. Active systems are often used for heating water. The collector is a dark color to absorb the sun’s energy and convert it into heat. Some collectors have a glass cover, collecting solar energy all year. Domestic hot water requirements can be met in part by active solar systems. In most cases solar energy will provide some partial water requirements during winter, but most of the summer season requirements. In most applications the solar system is used to preheat water going into a conventional water heater. Outdoor swimming pools can be entirely heated by solar systems, eliminating the need for a supplemental heater.
