Solar Power

The South West has higher levels of annual solar radiation than the rest of the UK.  Solar Energy can be used to generate electricity (solar PV) or heat water (solar thermal)

Solar Thermal

There are two types of collectors for solar thermal : flat plate and evacuated tube.

Evacuated tube collectors at the Lynton & Barnstaple Railway

Solar PV

A 3.36kWp system in Ilfracombe which generates nearly 3000kWh per year, equivalent to about 60% of the annual electricity consumption of the typical household.

 

The ideal orientation for a solar PV system is close to due south, at an angle of about 30 to 40 degrees.

Output from the 18.7kW system at the Calvert Trust, showing generation is greater on sunny days and in summer.
