<p>A solar energy collection system, instead of using a closed primary loop in heat exchange relation with a secondary loop passes water to be delivered to the end user through the collector 3 prior to storage in a storage tank 6. The flow rate of water through the collector is varied by means of a pump or valve 4 so as to increase as the power available for collection increases. Furthermore unlike conventional systems where the amount of water in the tank 6 is maintained substantially constant, the level is allowed to vary within wide limits, the tank only being refilled when adequate power is available at the solar collector 3.</p> |
