Solar PV installation, Crosby
Mr Vincent decided to install a 3.87kW system in order to maximise his energy generation and the feed-in tariff payments under the 4kW limit. The system is made up of 18 Sungrid 215W solar panels and a SMA Sunny Boy 3300 inverter. Sungrid panels were chosen for their superior build quality and high performance levels for their cost. They are also the market leader for their warranties with a 10 year product and 25 year performance warranty.
Mr Vincent's 3.87kW system is predicted to generate approximately 3,169kWh per year which will earn him around £1,308 per year in feed-in tariffs (41.3p per kWh of energy produced).
As well as the feed-in tariff payments, Mr Vincent will save around £247 per year from his electricity bills and generate around £38 for exporting his excess electricity back to the grid. This gives him an approximate income/saving of £1,593 per year, which gives a payback time of around 10 years for the system. He will also save around 1,723kg of carbon dioxide per year by producing his own green electricity. However from initial results Mr Vincent's system seems to be outperforming our initial estimates.
