What type of solar cells, Amorphous. polycrystaline, or monocrystaline?

polycrystaline. In fact, if a 10 w panel is made by poly and mono or amorphous, their output is same(10w), but size is different. The panel made by poly or mono, their size almost the same. And since of lower effiency, the size of amorphous almost doubled. Since the tech of poly was increased, the difference between poly and mono is become less and less, now 90% panel in market is made by poly.

Description of the white ones state they are "pre-Charged using Solar Energy" and "made in Japan". The black ones don't mention either one of these in their description, however it is said in the answer to another question asked here that they are made in china.

I believe they are Polymer, too light to be glass & a good buy for the money...JMO...I keep a pair on my book case & one on the garage work bench and a pair out in my shed...lol...

I like the Polycarbonate glasses the best. They stay crystal clear for a very long time. The other types get a cloudy appearance fairly quickly. I've had some of my Poly glasses for 5 or six summers and they still look as good as the day I bought them. I put them in the dishwasher about half the time and hand wash the other half. Hand washing does make them look the best.

Yes, it is photovoltaic, which means charged by light, not just sun. I have actually witnessed a solar panel show as charging during a lightning storm.

Seems like Mamdogtag has no idea one comment he says it's Mono and the other he says Crystalline. To me they look like they are Polycrystalline Silicon Solar Cells

Sorry, I cannot answer this one. I used it for making solar cookers. It is very reflective, and I like the 2 mil thickness.

I have four of these strings. The solar panel is plastic. However, I am a very big solar user. I have over 40 different kinds of solar lights and/or string lights. All have plastic solar panels. Many of these solar lights are five years old. All the plastic solar panels still work very well. Yes, on five of these, the solar panel has gone dull but the panel continues to work very well. Hope this helps.

You guys are right. The mono cells we use are pushing 19%. This is pretty high on the efficiency scale.

It seems to be very durable and the solar cell looks very efficient. I used it for 4 hours straight and works just fine. It has to see the sun so you have to transfer it from side to side if you use it the whole day. If I were you get 2 units and put it on both side. One wont be enough in the middle east.

I do not know for sure, but Per the Eplastics website The ePlastics OnLine Plexiglass acrylic plastic sheets including the Bronze and Gray acrylic solar control shades. - Note that the color, solar energy, and transmission values do NOT change with thickness. Color_______Solar Energy___Visible Light Colorless_______85%___________92% Gray 2064______36%___________25% Gray 2074______24%___________13% Bronze 2404____56%___________49% Bronze 2412____35%___________25% Bronze 2370____20%___________11% Not sure of the exact color, but this show that Polycarbonate sheets have some solar and light reduction even if clear.

The crystals are cut glass and quite sparkly. Some reviewers noted that they were plastic, but mine were glass. Once again, use caution when you assemble this light fixture because it has very sharp edges!

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.

A polymer glass material, it is VERY pretty though and looks quite expensive. Definitely worth it.

These are simple USB cables, though very short. Each has a standard USB port on one end, and the other ends are either the wide iPod-style connector, a micro-USB, or a mini-USB. If the solar device puts out the right power and if one of those combinations fits the phone and the solar power device, you should be in business.

The best type is a deep cycle, sealed battery. We sell DEKA solar batteries which are deep cycle, GEL batteries

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.
