Solar electricity systems, also known as solar photovoltaics (PV) capture the sun’s energy using photovoltaic cells. These cells don’t need direct sunlight to work- they can still generate some electricity on a cloudy day. The cells convert the sunlight into electricity, which can be used to run household appliances and lighting.
Domestic Solar PV Systems
Domestic Solar PV Systems are based on the size of system which best suits the individual household. Guide Price for domestic systems are shown in table below, with there annual and 20year returns based on 50% consumption and 50% export to the grid.
Commercial Solar PV Systems
Commercial Solar PV Systems are often based on the size of system which best suits the business, but can offer a very good investment as a standalone system, feeding directly into the grid. There is no maximum size, but this can often be determined by the location relative to 3-phase power lines. Commercial systems can be installed on cattle shed, poultry sheds, commercial workshops and warehouses, and also ground mounted if there is no buildings available, or they are not south facing.
Maintenance
Solar PV needs little maintenance – you’ll just need to keep the panels relatively clean and make sure trees don’t begin to overshadow them. The panels should last 25 years or more, but the inverter is likely to need replacing some time during this period, at a current cost of around £1,000.
