JA Solar

JA Solar, founded in Beijing in 2005, has grown into one of the world's top 3 panel manufacturers with annual shipments exceeding 50 GW. The company covers the full photovoltaic value chain from silicon wafers through to finished modules, and operates manufacturing plants across China, Vietnam, and Malaysia.

In Australia, JA Solar maintains a presence through its Sydney office and local distribution partners. Their DeepBlue series panels (415-440W) are widely available through WA installers at competitive price points. The panels use multi-busbar half-cut cell technology, which provides reliable performance and good shade tolerance.

JA Solar's panels are positioned as solid mid-range options — not the cheapest, but offering good efficiency and reliability at prices below premium European brands. Their 12-year product warranty and 25-year performance warranty are standard. As a Shenzhen-listed company with Tier 1 BloombergNEF status, JA Solar provides reasonable bankability for residential installations.
