Solar Water Heating Systems:

A solar water heating system harness energy from the sun in order to heat water. This will decease the use of grid supplied electricity. therefore using less grid electricity you as a consumer will be saving on the electricity bill, but the down side of using the sun as an energy source is that it sets at night. To overcoming this problem a heat pump could be add to the system. The hot water would be stored in a geyser for later use.
