Hello. I need to make a fairly quick judgment on whether a roof of 14 sq metres (pitched, south facing, second storey) would be big enough to take a 3kw solar pv system. Or if only able to take 2kw for example - whether such a small array will provide electricity to serve a 3-bed house (currently only one occupier with fairly low usage). Can give figures later. But it's this, or nothing, or resumed attempt to mend solar thermal outfit there. Be very grateful for others' experience/knowhow. I'd prefer to have integrated Solartrix style slates/tiles - not big panels or bolt-ons. Thanks
