JA Solar panel review
JA Solar are one of the largest hinese manufacturers.
The current panels we have access to in Perth are 370W and 390W half-cell monos.
br>
The efficiency of the 370W JA Solar panel is 20% and 21% for the 390W.
12 year defect warranty. A bit low when most others are 15 years and Leapton now 25 years.
The 370W panel dimensions are 1769mm x 1052mm and they usually have a black frame.
It is a 120 half-cell 'P' type monocrystalline design. Normal.
Salt mist/ammonia severity resistance rating is 5. The highest level possible is 6.
The temperature power loss factor is -0.27% per °C . It means that for every °C the temperature rises, the output reduces by 0.27%. That's fractionally (0.01%) better than the usual 0.28%.
Price is normal at approx $185 per panel, less STC subsidy of $185 = Free.

Would I put JA solar panels on my own roof?
I see from our records that we have installed very few JA panels over the years, so no, probably not as I don't have enough personal experience with this brand. I'm sure they are just as good as Longi, Jionko, Canadian, Trina, Leapton, Seraphim etc
