JA Solar – Company History

JA Solar was originally founded in 2005 and is based in Beijing, China. The company was listed on the US NASDAQ exchange back in 2007 during an early growth phase and has recently been acquired by JASO Acquisition Limited which effectively has taken the company private again.

The company has 9 manufacturing facilities in China and one in Malaysia and Vietnam with a total annual production capacity of 42.5 GW (reported by Bloomberg NEF). This makes JA Solar the third largest producer of Solar Panels as of September 2021.

JA Solar has 25,000 employees as of 2022 working across 32 factories and branches around the world.

What is a Bloomberg Tier 1 Solar Panel?

Bloomberg’s infamous tier 1 ranking is NOT a measure of Solar Panel quality in any way. It is simply an indication of the bankability of the manufacturer based on publicly released information on the financial health the company. This should give you an idea if the company is a large, well-known manufacturer.

JA Solar is listed as a tier 1 manufacturer in Bloomberg’s Q2 2020 report.

What is PV Evolution Labs Top Performer?

PV Evolution Labs with support from DNV GL independently test solar panel reliability. The tests are voluntary, with solar panel manufacturers paying to participate in the testing. This testing process is internationally renowned and is an accurate reflection of the solar panel’s performance.

JA Solar are named as a top performer in the test of 5 performance tests(thermal cycling, Damp Heat, Mechanical Stress Sequence, LID+LETID and PAN) in the latest 2023 report.

Why is office location in Australia Important?

Most solar panel manufacturers entering the Australian market first set up their distribution channels and worry about customer service later. This has led to many unhappy customers who are left trying to contact Chinese head offices to claim on their 10-year product warranty.

Relying on your solar installer is not always an option as we’ve seen many residential solar installers (including the large ones) go out of business well within the lifetime of the systems they are installing. 

JA Solar list an office in Newcastle, however this is for an accounting firm called PKF Newcastle. This will not be helpful to JA Solar customers in claiming warranty.

JA Solar Panel -Points of Difference

There are many solar panels out there, what makes Canadian solar panels stand out?

One of the world’s largest solar panel manufacturers

JA Solar is one of the largest solar panel manufacturers with third-largest solar module capacity (reportedly 42.5GW/year in 2021). JA Solar has focused on producing a mid-market solar panel for the masses that combines reliability with an affordable price point. JA Solar is one of the most competitively priced of the ‘big-name’ solar panels on the market.

JA Solar Panel Technologies

Most of JA Solar’s products have been approved by the Clean Energy Council (listed under the parent company Shanghai JA Solar Technology Co Ltd) for the Small-scale Renewable Energy Scheme – Australia’s home solar rebate program.

MBB Half–Cell ModuleJA Solar MBB Half–Cell Module

JA Solar have a range of solar panel modules featuring 6 multi-busbars and PERC Half-Cut silicon cells. The number of cells each solar panel has ranges from 108 to 144 cells with the dimensions of the panel increasing respectively. The rated maximum power output ranges from 340 watts  for the smaller dimension panels (JAM60S10/MR) and up to 555 watts for the larger dimension panels (JAM72S30/MR) which are better suited for commercial projects or solar farms.

Bifacial PERC Half-Cell Double Glass ModuleJA Solar Bifacial PERC Half-Cell Double Glass Module

JA Solar has 5 different bi-facial solar panels available in the Australian market. Bifacial solar panels create energy on both sides of the panel so reflected energy from the ground or roof can increase the output of this panel by up to 20% in the right conditions. These solar panels are traditionally used where the solar panels are tilted so that there is increased reflection to the underside of the panel. These panels are more durable than traditional panels as they have a glass front and back sheet and come at a cost premium.

Pros and cons of JA solar panels

  • Listed as a top performing solar panel by PV Evolution Labs
  • Tier 1 Solar Company by Bloomberg New Energy
  • No premium product offering with 25 years product warranty
  • Founded in 2005 (shorter history compared to similar Chinese solar brands)

So, are JA Solar Panels worth buying?

JA Solar Panels stack up well for as an affordable mid-range option from a company with a solid financial backing and reputation.

One concern with JA Solar is that they do not have an office here in Australia. JA Solar has provided Solar Choice with evidence that they employ 7 staff in Australia who they advise can support with warranty claims. Their updated warranty document in 2021 does provide an option to contact JA Solar on Australian phone numbers :+61 289 122 165 or email:  service.au@jasolar.com
