Using a solar hot water system is great - as long as you use it in the correct way. In winter people will often turn the electric booster on for the solar hot water system; unfortunately it's easy to forget and leave the booster switch on even when the sun is shining which wastes energy and potentially hundreds of dollars per year.
Most electric booster switches are found in the switchboard labelled as "hot water" so take a look and make sure your boosters not on.
To help households manage booster usage Alice Solar city provides an incentive for the installation of a one-shot booster relay which not only indicates when you need to boost but automatically turns the booster off once the water in the tank has been adequately heated.
