I have had some topics up before about Solar PV but i cant seem to be able to find it again! , me and my partner are building our own house and we are looking for Solar PV, has anyone experiences with this and any costs? we were thinking a 5/6kw ground system as our roof is taking up by quite a few roof lights, although its not out the question.
we have some calculations and wondering if a 60% / 40% split is a good starting point 60% being used and 40% going to the grid under the tarrif scheme at about 4-5p a kwh.
We got the PVGIS from someone on here and its saying roughly be 4400kwh at our location with a 5kw system, so i worked out if we split it 60/40 we would have about £1300 saved a year based on 28p per kwh which is the forcast cost of elec come april, and £180 back from feed back based at 5.5p. but the key question is if its likely 60/40 split is a smart estimate, my wife works from home so im thinking thats in our favour and im also thinking if we got the washing,dishes, dryer, hot water etc all done at peak times then it should really help.
currently we are due to move in come March/April and were all Electric house with a ASHP.
