How much will a PV system cost, and does the government help?

The total system cost depends on the size of the project. The larger it is, the less you have to pay for every unit of power installed. The new government subsidies mean that you sell the energy you produce to EAC at a higher price than they sell it to you (about three times as much), so every second month a cheque comes to your front door, even if you’re away from home. This way the payback time can be very low, between 6-10 years for a system that will work even beyond 30 years.
