These kits come complete with all the materials needed to connect the solar panel to an existing water heating tank. Perhaps the most extraordinary thing about SolarRoofs's products is the low price. Additional collectors can also be added. The collector's horizontal orientation and optional colors give it a pleasing skylight appearance.
Copper tubing is included along with brass compression fittings.
The basic package uses a simple timer to operate the circulation pump during times of the day when heat is potentially available. Better performance can be achieved with the optional differential controller, which compares the temperature of the collector with the storage tank and operates the pump only when sufficient heat is available.
