Solar panels

  • We had a 2kw array of solar panels installed on our roof in 2010 by SRG. They have worked ever since with no problems. Never quite producing their full rating but giving a good return on investment (especially when compared against money in savings). We had them installed when the feed in tariff was at its most generous; although the feed in tariff is now less the installation cost have about halved now so I imagine it’s still well worth doing. But do your own calculations on current costs v return. The rest of your electrical installation (i.e. house wiring) will be checked so if you have any doubts about the safety of it you will need to budget for rectifying that as well.

  •  In common with most wera houses we have no cavity walls. We are end-of-terrace with a south facing end wall. As internal wall installation is impractical and external solutions I find ugly we are experimenting with ivy. As the last winter had very little serious cold it’s insulation against that is un-tested. Certainly on the few hot days we have had it has prevented overheating in the rooms with an exposed wall. You hear horror stories about ivy damaging walls, as far as I could judge if your pointing is intact it doesn’t cause problems. If it does in future we will be posting on the wera list looking for help. [Shaun Davies, Baden Road]
  • Draft stripping is the cheapest, most effective energy saver there is! [Shaun Davies, Baden Road]
  • When we had the flat roof on the (original) back extension recovered we added insulation on top of the existing roof under the new surface. This made a big difference to the 1st floor back bedroom. [Shaun Davies, Baden Road]


How much CO2 our electricity produces

Our electricity comes from several different sources (e.g. gas, wind, …) which produce different amounts of CO2; since the balance of sources varies from hour to hour, we can reduce our CO2 impact by timing our use of electricity. Here’s an explanation and source of information.
