It is important to understand that a grid connected Ssolar PV system does not need to provide all of the electricity you consume in order to be of great value. A small system providing an average of, say, half of your average demand can reduce your electricity bill dramatically. Five years ago, a small system like 1.5kW would have been the most cost efficient. Today, with the cost of a solar PV system being about one-third of the level 5 years ago, most households have opted for 3-5kW system to reduce their grid consumption more. As the cost of rooftop solar systems has declined while the Residential Tariffs charged by Synergy have increased, installing larger solar PV systems makes more sense. We are happy to provide you with a system that supplies nearly 100% of your energy needs and help you calculate the optimal size that you should go for.
