PV Solar Panels

I am investigating installation of Solar Panels before the Tariff plummets in January. Does anyone have accurate figures of Electricity cost before and after installation?

I'm on E7 meter so the figures relate to 7am to midnight usage.

2009-2010 (pre solar) 5199kWh
2014-2015 1700 kWh

In the meantime we've changed several appliances to A+ rating and all lamps are now LED or CFL - so not all the savings are due to PV installation.

We've also save quite a bit of gas by having a diverter to heat the water with excess power.

Hi. I save about £180, but every household will differ depending on size and orientation of system, current level of consumption, and the ability to make use of leccy during the day.

If it helps, the figure in the PV FAQs section 1.3:

£120 (probably in the £80 to £160 range).

is based on crowd thinking, with folk on the talking about my generation thread being asked for their opinion.

That's a range that should be obtainable without too much effort, above that might require changes to patterns, such as using timers to switch on the washing machine during the day etc, etc.

Mart.
