Jay contacted me and I sent him links. I am placing them here, also. We have not built panels yet. They don't work well underwater. It has not stopped raining here for over 3 months. I'm talking all day and all night.
Look here :
Go here for cells : http://www.ebay.com/sch/i.html?_from=R40&_trksid=p5197.m570.l1313&_nkw=1+KW+Solar+Cells&_sacat=See-All-Categories IF you can buy tabbed cells, that is easier to solder. All you need to do is connect them. These things are THIN and FRAGILE.
Go here for build series of 3 parts. http://fieldlines.com/board/index.php?topic=145005.0
This is the best info available.
I'm very interested in the actual LED fixtures You posted about. Any more details about exactly what you bought ?? I know nothing about LED lighting, but, I have made 3 modded light bulbs with LED's sticking out of them. We use them for temp lighting when the lights go out (REAL regular). I just put jumper leads to a 12V UPS battery.

Ultra - Super Bright Clear White
5 x Led Lighting Modules
There are 3 high quality led in the module ,
Led Type Smd 5050 Three chips Very Strong,
Undercabinet or cabinet lighting,
Many using area;
Home,kitchen,hidden lighting,bars,tv back,under beds,in pools,cars,buses........
These photos show 10 modules
12 volt low voltage,(60ma , 0.72W per module)
Low energy consumption,long life time 80.000 hours
Easy to install yourself
Strong double side adhesive on the back of each
and you can mount with screw !
Two Modul Size Found, Chips Same
Model A: (3 3/4" long x 2/5" wide x 1/5" thick),
2 1/2" wire spacing between each module
Model B: (2 1/4" long x 2/5" wide x 1/5" thick),
3 1/5" wire spacing between each
Each module can be cut
LED color is Clear White (not Yellowish,not Bluish)

I'm wondering if you could put copper piping directly under the metal backing of the PV solar panel and heat the water in the tubes while also generating electricity. I'm thinking that if you have a smaller, energy efficient house, then the roof space might be limited to have both a PV panel and a solar hot water panel.

I plug the VOM into an outlet and watch the voltage range from 105 to 128. I have confronted ICE the local monopoly Power and Communications Company and their engineers say that is perfectly OK voltage. Lights out is fairly common, averaging up to 20 momentary blinks per week, sometimes.
Light bulbs don't last for very long. I'm about to start wiring the house for low voltage lighting and power stations.
When I lived in Arkansas, I sold wind turbines, Solar Panels and Towers, along with TV Antennas and rotators and boosters. Had a guy convert a booster to 12V. He said there was a device to take 120V AC and change it to 12V DC. He bypassed that device. I ran that booster for several years with no problems.
I would like to convert the Modem and Satellite receiver to low voltage, if possible ?? Anyone here know how to do that ??
I recently found some LiFePo4 batteries for 34 cents per wh. I need to see about shipping. I want to start with a 12V system, and, lead just doesn't get it, anymore. 2--220Ahr 6V Golf Car batteries would run me over $400.00 if I bought them down here, and then, have to have them transported over the mountains to me.
I should have my 10-1 gearbox here any day, so I can start building my Wind Turbine. Tower will be the expensive part. Probably use 1½" Angle for the lower section and 1" EMT Conduit for the upper section, crank up style.
mean?The researchers hit the 114 percent external quantum efficiency
