How Solar Works
From sunlight to electricity
-
Solar panels capture the suns energy using photo-voltaic (PV) cells. These cells produce DC electricity whenever there is daylight. The more intense the light, the more electricity is produced.
-
PV cells don't need direct sunlight to work - you can still generate electricity on a cloudy day or slightly shaded roof.
In order to go solar you need two things:
-
Unshaded roof space, south facing will generate the most electricity.
-
An amount of money, typically between £4,000 - £7,000, to invest in solar.
Benefits
The financial benefits of going solar are two fold.
When combined, result in an estimated year one benefit of £459. Subject to inflation, the overall benefit of savings and payments could excess £15,000 over 20 years.
Save money on your electric bill
The typical saving is around 35% but this can be increased up to about 80% by adding a battery storage system or by using any surplus energy to heat your water via an immersion controller.
If you use half of the electric generated you will save around £245 on your current bill.
Get paid for exporting excess
You will be paid for surplus electricity exported back to the grid.
This is paid at a rate of 5-6 pence per unit via the smart export guarantee scheme and could be worth around £85 a year.
