How does a Traditional Drainback Solar System work?

Traditional Drainback Systems use a pump to circulate water or glycol in the collector loop, which drops into a reservoir tank when the pump stops. They also use a differential controller to start the pump (or the pumps) and to route the water into the system. This process begins whenever the sensors attached to the collector detect useful sunlight available (which happens when the temperature in the collector is higher than the temperature of the water at the bottom of the storage tank).
