Glass-glass laminate solar panels

We have a south facing conservatory with an angled double-glazed glass roof.  We are thinking of replacing the glass roof with solar panels (which produce electricity) but are struggling to find the right product.  The sticky panels you sell might be an option depending on weight. But do you know of a product which would replace ordinary double glazing with similar thickness (and weight) glass panels which have integrated PV cells?

Yes, it is possible to get solar panels that are glass-glass laminates - ie the solar cells are sandwiched between two sheets of glass - rather than between a layer of glass and a sheet of metal or plastic, which is more normal in framed panels. See http://www.solarcentury.co.uk/products/low_carbon_building_products/solar_glazing for more details.

Glass-glass laminates are effectively double glazing with integrated PV cells, which sounds like exactly what you want.

The adhesive-backed panels are not particularly heavy incidentally. I shouldn't imagine the additional weight would be a problem on most roof structures if you wanted to consider them instead.
