I think the point Solarcity is making is that his (and mine too) understanding is the data on Google Earth is limited, dated and doesn't show shading around the clock so it's almost impossible to give a sap rating because you haven't taken shading into account. So I guess technically if you quote without fully understanding you could be mis-quoting.

As you know we all tend to look after each other on the Forum if we can, so if we're missing a trick wth Google Earth and you can calculate the shading and produce an accurate SAP from it we'd all love to know about it because it would save us all loads of time and that's quite important to us all at the minute.

If you can't do that then I'd just be concerned that you might back yourself into a difficult situation with someone like REAL if they asked how you were doing your SAP calcs. As I say, we're all just watching each other's backs

I use bing and google before we survey, but it should only be a guide as there maps aren't up-to-date. So trees will be bigger however on fixed objects they are good to check your shading predictions !
