    i've browsed the net and cant seem to find a definitive size of PV panel per 1kwh.

    does anyone have any good links?

    done some more searching, is it fair to say 1m2 = 1kwh?

    Depends on so many things, angles, cloud cover, dirt on the face of the panel, orientation or will you track the suns movement? even manufacturer.

    30 degree angle facing south, it is more for a design stage for CSH level 3 and a rough size needed for the panel so can work out an approximation of roof area.

    the panel needs to produce 1kwh on average to make the TER/DER work.

    I kw panel might produce almost 700kWh per annum and the panel would cover about 7 m^2 of roof -- any help? thats all optimistic too

    they dont talk about kWh for solar pv just kW

    This from a friend who is a PV installer (not sure of the panel manufacturer):

    "A hybrid panel (best available output) can deliver 230wp over a collector aperture of 1570x805mm (1.26m2) (182Wp per m2), or a module with a 315wp output, with a collector aperture of 1559x1046mm (1.63m2) - this delivers 193Wp per m2."

    Hope that helps
