Wow! 

Great source of Solar Power knowledge here...will be seeing you help one day in the future :-)

God bless

that's a great idea Mike!  why not use old CDs?  might look like giant robot snake skin when you're done, but would be a neat way to recycle scratched disks!

Concerning the shadowing under the deck, in the winter most of the underside will have direct light, which will become less as the sun rises in spring through summer. Summer has the largest amount of shading, which is good for keeping the temperature down but not for beneficial light for the plants. I was part of the initial optical disk drive development so I was thinking I could bounce light off some surfaces to get the photons toward the back of the deck area. Look at the graphics. Has any one ever done anything like this to help get light to plants in shadows?

i see.  i was not assuming that roof-mounted panels would be set at the angle of the roof, but rather at 40-60 degrees from horizontal.

looking forward to seeing it all come together!

Averan, The angles for the panels (glazing, solar electric, solar thermal) are set for winter where the greatest need is required and the days are the shortest. See below. The solar electric panels have been set at this setting for the past 17 years. In the summer the sweep of the sun is much greater and has more time on the panels even though there is a Cosin loss, but on the average we get the equivalent of 6 total hours of sun this way all year long. If placed flat on the roof, like so many residents were conned into doing in the last government give-away, a typical shallow roof angle (easy to walk on) with glass covered panels would actually reflect the light away as the critical angle of incidence 42 deg.

looks good!  the PV panels look like they are mounted incorrectly and should be up top on the roof where they can be set at a proper angle.  also the solar hot water would benefit from being on top as well...  and i question the south deck shading the grow room.  seems it would cut too much light to grow anything.

must be a lot of fun though to plan an integrated AP system!!

Nice :-)
