The decision to go solar is a savvy financial move. Many businesses are realising this. The cost of energy on commercial contracts with Power and Water is close to 30 cents per kilowatthour. The cost of supplying your own energy needs with a solar system on the roof of your shop or warehouse is around 10 cents per kilowatthour (LCOE or levelised cost of energy). Any energy your business can make for itself is a very significant saving. Return on investment is over 10 per cent.
The return on your investment in solar is seen as cost savings in reduced electricity consumption as well as income derived from energy sold to the grid. Rate of returns can be fairly high, and this depends on your business’ daily energy consumption patterns as well as your power purchase agreement with the network provider. For all larger systems it is necessary to conduct a thorough customised energy use analysis to get a clear picture of an appropriate system size and design that will maximise energy independence as well as rates of return.
