JA Solar solar panels reviews

JA Solar is a Chinese company that that is one of the largest manufacturers of solar panels in the world. They produce tier 1 solar panels that carry a 12-year product warranty, which is becoming standard for the industry among better quality brands. Some offer a longer product warranty, but they'll often be pricier panels.

JA Solar has an Australian office located in Newcastle, which means there are people in the country you can contact in case you have a problem. As their panels are salt mist corrosion resistant, they are suitable for installation anywhere in Australia.

JA Solar Pushing To Be Planet's Most Prolific PV Panel Producer

JA Solar states it has shipped 73 gigawatts of solar panels (cumulative) as at the end of the second quarter of 2021. In early 2020, it was named the second biggest shipper of panels in the world for the previous year, behind JinkoSolar.

JA Solar Production Facilities

The bulk of JA Solar panel manufacturing capacity consists of 9 factories in China. Four near the giant metropolis of Shanghai and 2 in the vast Beijing conurbation. They also have a 400 megawatt facility in Malaysia, which is handy for avoiding US tariffs on Chinese made panels, and they have a 200 megawatt assembly plant in Vietnam.

JA Solar Panels Efficiency

JA Solar panels currently available in Australia and listed on our solar panel comparison table have a conversion efficiency of between 19.5% for the JAMS66 360W and 21% for  their JAMS20 390W monocrystalline module, both of which are quite respectable for solar panels at this end of the pricing spectrum.

Unlike some solar panel manufacturers, JA Solar don't cheat by not including the frame in the efficiency calculation.

Also quite respectable is JA Solar panels' temperature coefficient, which for the panel models mentioned above is -0.35%/°C.

JA Solar's Bankability

As we saw back in 2008, independent surveys of companies’ financial health are a vital part of completely failing to prevent economic disasters.

In order to further improve our ability to fail to avoid economic disasters, each year Bloomberg New Energy Finance performs a survey to estimate the financial health of solar manufacturers. This is done by basically determining how likely lenders would be to accept a solar farm using a particular manufacturer's modules as collateral for a loan.

In 2014 JA Solar came 3rd out of 11 companies on this measure of bankability. And in 2016 they came 6th out of 15 companies putting them into the top 40% of all those surveyed, which was better than the company immediately behind them that was only in the top 47%. It's not clear how the company scored since that time as BloombergNEF doesn't publish the scores online any more.

JA Solar And The Hemlock Saga

Hemlock, an oddly named US silicon producer, was attempting to sue JA Solar for close to one billion US dollars, but the two companies arrived at a settlement back in 2016. As part of the settement, JA Solar entered into a new Long-Term Supply Agreement whereby it was to buy solar grade polycrystalline silicon products from Hemlock on a quarterly basis until October 31, 2026.

The original dispute arose after JA Solar had agreed to purchase $103.5 million US worth of silicon from Hemlock and decided not to do that after silicon prices fell and they could get it more cheaply elsewhere.  Rather than sue them for US $103.5 million for breaking their promise and screwing them over, Hemlock decided to sue for almost one billion US dollars instead, because of optimism, I guess. 

JA Solar Goes Private

In July 2018, the company announced the completion of its merger with JASO Acquisition Limited and that it had ceased to be a publicly traded company.

JA's Old Robot Mascot Gave Me The Creeps

In general, I have nothing against robots. Some of my best friends are 'bots. I regard them as hard working members of society just the same as the chair that is supporting me, my microwave oven, my automatic enchilada maker, or my ninth grade Geography teacher.

JA Solar's robot was just wrong. I believe it had solar cells in its face. That makes no sense at all. Yes, my energy enters my body through my face, but that's because I'm a human and 600 million years ago some worm decided to split the tasks of eating and excreting between two different holes. And thank god for that.

But robots are designed. They didn't come about through random worms deciding to no longer poop out of their faces. We made that robot and we made it so the only way it can get full power from its solar cells is to stare at the sun. And that is just stupid.

Thankfully, it appears the creepy little robot mascot is no more.

STVC Solar Scorecard

Each year the Silicon Valley Toxics Coalition (STVC) produces a report grading solar panel manufacturers on environmental and social responsibility. A low score on this report doesn't mean a company is awful, it can just mean that information wasn't available. So a high score is a good sign while a low score is not a good sign, but not necessarily a bad sign.

But regardless of how good or bad they were, JA Solar's score in 2013 stank with a total of 8 out of a possible 100. In 2014 their score was marginally less smelly with 10 out of 100. But in 2015 they hurled themselves up the scoreboard and nabbed a score of 77 out of 100. In 2019, it had reached 92.

I don’t know how they managed that. Maybe JA Solar hired one of those coaches from a Disney sports movie who somehow manages to turn everything around despite being a doofus?

Nah, apparently the score was low previously due to communication issues and not providing sufficient supporting documents to STVC.

I Am Fine With Recommending JA Solar Panels

JA Solar panels are reliable and cost effective. While they had dropped  a little on bankability scores in the past, it is not really possible to draw any firm conclusions from that about how likely they are to remain in existence as a company. The fact they are tier 1 indicates they are considered to be a reliable manufacturer that will probably stick around.
