Solar system in Oxon/Wilts

Just a thought - we were thinking of adding an electric underfloor heating element in the kitchen we are about to redo (our ultimate goal of a wet system is not going to happen for a while, due to a few other considerations). Am I right in thinking the immerSUN would work with this?

Yes it can. Take a look at pages 32-35 of the installation manual. http://www.immersun.co.uk/uploads/Instruction-Manual-v1.3.pdf

But with all of this, remember that with a 4kWp system your daily generation in winter will probably not be enough to heat the water, so space heating, whether underfloor or some sort of radiator is really for March or April through to September/October. For the rest of the year you will get some benefit but will have to use the "boost" function to feed leccy to the immersion etc if you continue to use them in winter.

One other thing to think about with the immerSUN is whether to use a hard-wired CT clamp sensor or spend £49 on a wireless sensor, which needs a mains feed to power it (rather than batteries). I have used the wired sensor. It is about 5m in length and can be extended using CAT5 network cable - I think this is described in the installation manual. Just depends on where you want to put the immerSUN and where your cables etc run...

Thanks pinnks. I guess you are right - the reality is that there won't be too much spare electricity for anything other than hot water. I notice that the iBoost is cheaper, so maybe that is good enough.

Thanks also for the wiring info - I will ask our electrician when he is here about the kitchen

Hello everyone. I have had a quote from one of the above companies. It is not as good as some of you have got: 14 x 285w Trina black panels and an SMA inverter (plus the other bits and bobs) for £5900.

I have been keeping the PV project on the back burner, as I have a kitchen renovation that is nearing the start point, and need to remortgage in about two months, so an a little uneasy taking out a new loan to pay for the PV. But I am also aware that the FIT scheme may come to a juddering halt. So a difficult balance. How did some of you get those prices above? Hard bargaining?

Forgot to ask whether that brand of panel is any good...
