How to make a ground mount system look pretty?

i like the bifacial panels, but they seem like such a waste. too bad regular panel manufacturer's don't make a panel that lets light partially through.

    to me this is a bit of a gimmick because when you buy a pv you get an stc rating with it. a bifacial at 200w won't do better than a standard 200w pv as 200w is 200w. now a question comes to my mind is if the testing allowed any light to reflect back to the underside of the pv making the reaching of the stc rating dependent on receiving so much light to the backside of the pv to get the same 200w as per my example?

    also, letting light through a pv is not converting it to electricity by the pv. the underside is supposed to get ambient light and cannot get direct sunlight without either depriving the main face of the pv operation or using mirrors and other reflective surfaces that would be tantamount to the high temps seen by concentrating cells and bifacial pvs aren't rated for concentration or higher temps.

    it seems like a good idea on the face of it, but with further thought it is no better and may even be worse than other pvs.

    you're right bifacial is a gimmick.

    but I would like to single sided panels that allow light through instead of blocking it with white or black tedlar like most panels today.

    Rolland, there are lots of that type out there... I see them frequently on a mailout I get from http://www.globalsources.com/gsol/I/Solar-panel/p/sm/1028882432.htm

    Canadian Solar have a model that's transparent between the cells, called 'clearpower'.

    west branch and stephen Dv thanks for the cool suggestions.
    I've never seen a panel that was half empty to let light through. I wonder if the manufacturer has any cool architectural designs/photos?

    Niel you are wrong about the STC rating, the backside is not included. You pay for the 200 watt panel however you may produce much more. The sanyo fills a niche market, where bipv or looks are a concern. I have seen some really neat sanyo installls. Now if you looking for cheep it not the right panel, however just because the panel isn't a cheap Chinese bargain basement panel does not mean it's a gimmick.

    i did not say that it was or was not included, but cited my question if it was or not. i am right that it is a bit of a gimmick. good to know that it is possible to go higher than rated, but for me personally not at that price for the pv.

    Most amazing thing I have ever measured is a Wattsun tracking 1800 watts of the Sanyo bi-facials in snow country. I keep telling the owner "I know when you go on vacation" so put a camera on them.

    Definately a thing of beauty!
