Solar PV and thermal systems feedback

[Scrag Meister]

Anyone had a solar pv (electricity) system installed.

Recommended? Cost? FI Tariff received? General cost savings?
Thinking of installing on our new place when we get in.

Also considering Solar thermal system too if anyone has any experience of this I'd be interested to hear your opinions.

Thanks

It's on my todo list after the extension to the south wing is completed.

I believe you can get PV and thermal combined units now. The idea being the cold water fed into the units cools the PV panels which makes them more efficient and you get warm/hot water out which is fed into you gas/oil central heating boiler so it only has to heat warm water rather than cold.

Next door has both but I'm not sure if they're combined. The thermal one just pre-heats water in the storage tank so on hot days they don't need to heat the water at all, on cold days it raises it from freezing to just cold.


My mum has just had a heat-exchange air heating (and dehumidifying) system fitted which apparently is quite efficient.
