Our energy generation

We're not content just to help others set up their renewable energy schemes, we believe that affirmative action starts at home.

In February 2010 we decided to set an example and install our own solar photovoltaic (PV) arrays. The installation cost Severn Wye less than £2,500 as we were fortunate to have support from the Low Carbon Buildings Programme (Phase 2) and the ScottishPower Green Energy Trust. This enabled us to install 28 hybrid solar panels covering around 35 m² of roof space. The arrays face south-east and south-west. We have two inverters as our panels are mounted on separate orientations. There are two Fronius IG30 Inverters, with two springs per inverter. The roof has a tilt of approximately 30 degrees.

The rated capacity of the ...

The rated capacity of the system is about 5.9 kWp - the maximum output under ideal conditions, which we sadly don't get much of in Gloucestershire! Despite this, the system did reach its predicted energy yield more than three months ahead of schedule, and it's still comfortably exceeding all our expectations.

  • Year 1 total generation - 5587 kWh
  • Year 2 total generation - 5597 kWh
  • Year 3 total generation - 5309 kWh
  • Year 4 total generation - 5434 kWh
  • Year 5 total generation - 5659 kWh
  • Year 6 total generation - 5452 kWh
  • Year 7 total generation - 5238 kWh

Whilst we don't benefit from any FiTs payments (we installed the system before the feed-in tariffs were introduced and because it was part-publicly funded) there are still plenty of benefits to be had.
