TIPS ON GETTING THE MAXIMUM BENEFITS
Solar power systems definitely show a good return on investment. It is cheaper to to generate your own electricity than draw expensive power from the grid.
It does not make you money to export power to the grid, so in order to get the best return on your investment, use as much of your own power as possible. Therefore, the aim is to run most of your appliances (dishwasher, washing machine, clothes drier etc) during the day when they will use electricity generated by the solar power system rather then draw expensive electricity from the grid.
Rearranging your tariffs can also save you money!
Pool pumps and hot water systems are very heavy users of electricity. It is inexpensive to add a timer to the hot water system so that you have control over them.
Both your pool pump and your hot water system would be better on your main tariff (tariff 11) so that it uses the power generated by your solar power system and doesn’t draw expensive power from the grid.
