Re: Solar deck instead of solar panels

thnk
1.solar technology continues to advance. If you have panels.easier to swap out.
2.cells break ( see above) if glassed in hard to swap out.
3.angle of incident light important determinent of output.
4. maintaining integrety of connections problematic.

Did energy calc.- if I get ~3y from panels they have paid for themselves at current fuel prices.

If to put on deck would use new flexible panels and deploy as needed.
Personally spec'd cored hard bimini. very rigid platfom for panels and out of harms way.

Is there a transparent substance sturdy enough to walk on that still will allow enough light to be transmitted thru it? I was thinking about placing something like a plexiglass housing over it. If so would you place it on the panels or raise it up enough to not touch it?

Re: Solar deck instead of solar panels

I have been thinking about doing this, but i didnīt for the following reasons:

-Good solar panels use special coated glass that reflect little light. Normal glass reflects a lot and cuts down on the efficiency. Gelcoat or whatever you put on there will undoubtetly be even worse than normal glas. If you make it antiskid, it will be downright terrible.

-Even little pieces of shaded cut down a lot on the energy output.

-Solar cells are very sensitive to crackling. I dont feel safe walking on them and maybe sometimes dropping pieces of stainless equipment or tools on them.

When i buy myself a campervan and i wont be dropping **** on the roof, walking on the roof and dont need anti skid, i do however intent to do this. Simply because cells are cheaper than panels and this way i dont need to build frames.

Sorry for not believing in it, it sure looks cool, and who knows, maybe im wrong

I only have one thing to say about the solar deck....


Awesome!!

Re: Solar deck instead of solar panels

I'm not an expert on solar, but, my guess is that for the square footage of solar cells, not a lot more power will be produced than an array mounted off the stern that doesn't have the problems with ventilation, thick overcoatings, and shading.
