What type are the panels, monocrystallin or polycrystallin?

They are monocrystallin. I am thinking about selling mine if you're interested. Thinking of going to a roof mounted setup. My email is products@bti-labs.com.

My understanding is that they are mono-crystalline, hence the relatively high output.

It doesn't say in the manual.....but I think it's quartz. I think the element is very durable. The only issue I have had with these in the past (I have had 3!) is the power cord....don't know why. The last one burned out after only one winter.

For us these were the replacement panels. We had a couple pieces that cracked due to being folded the wrong way so we got this two panel set to swap them out.

This is one solid piece of lattice that looks like three lattice squares stacked. A single lattice square is 19 1'2 by 19 1/2. This triple panel is 19 1/2 by 55 1/2. This is a great product, very solid.

This site: http://www.earthtechproducts.com/solar-power-panels.html (scroll to bottom) has a good description of the different cell types, advantages and disadvantages. In general, mono- is more efficient but also more expensive than poly-. However, efficiency for mono- cells falls off more with increasing temperature than poly- cells. In higher temp setting (e.g., southwest desert), the poly- cells may yeild higher efficiency.

They are Mono crystalline and very good ones. I wanted to get more of the 250 watt but too expensive, so I got a couple of a different brand for 310 and I'm happy. If you like the price of the Renogy panels, you won't regret buying them.

I believe them to be polypropylene. We had one set and recently bought another. They are made in the USA!

They are aluminum just like the rest of the frame held together with plastic interlocking clasps. I have a single spring mattress on them and so far it has been a comfortable sleep.

Side panels are veneer - probably over particle board. It is structurally solid though.

They are 1/2" non-braced particle type board. You can't tell from the picture, but have a trapezoid shape when viewed from the small side.

The hinges on this unit are all non metallic. The hinge pins are molded and simply need to driven into place and lock. The pins on my unit were part of either the top or the back panel, I can't remember which. The only screws are those used to attach the two plastic straps that keep the top from falling back past vertical when fully opened. I assembled my entire unit in less than five minutes! Fabulously easy!

The panels appear to be a cheaper wood. The drawer bottom, back and shelf look like plywood. Top, drawer and all supports are solid wood. I am very happy with the unit I purchased. Assembly took several hours.

No idea what's up with those white ones. They are actually series 4 901s. They make walnut (real walnut veneer) and black ash (plastic veneer). The walnut are nice cabinets.

No idea. They are sturdy and so nice because of the interchangable factor. We don't use the door much just resection for whatever we need it for. Have a total of 10 panels.

Dimensions of the panel are listed in the title. 216" long x 15.5" wide x .5" thick.
