I do not have any experience with them. The price is pretty good, but a couple things caught my eye.
The ratio of Isc to Imp is the highest I ever saw. 4.68A : 3.33A It's usually less than 10% or so.
It is pretty big for only 55W. A meter square!
The P Type module only has a 10 year warranty.
The "P-TYPE PV modules wll maintain more than 90% of minimum rated power for 10 years (based on data from silicon PV modules installed over a month under conditions of 25ºC, A.M. 1.5 and 100m W/cm2)" makes it sound like it will be worn out shortly after 10 years?
IMHO, there website has quite a bit of carefully worded information that could be misinterpreted by the average person...
- "Kaneka's amorphous silicon PV module (a-Si) has superior light absorption per nominal watt power. Compared with mono-crystalline silicon PV modules (c-Si) or poly-crystalline silicon PV modules (poly-Si), it generates considerably more power per nominal watt power."
That almost sounds like they more efficient? They are not, or they would use less space than crystalline.
- Their comparison chart looks kind of impressive, but it starts at 600 at the bottom. If it started at 0, it would be more obvious the difference the chart shows is only about 7.5%.
- Energy Pay-Back Time is shorter, but if the panels last half as long, then it is not as efficient?
- Environmentally Friendly because it uses less a-Si material, but the 55W panel weighs almost 2 and a half times more than a 65W Kyocera. It weighs almost 3X as much as a 54W Kyocera.
- The thickness comparison does not take into account that the material needs to be over twice the surface area.
Just saying be careful interpreting what you read.
