Top-Tier Global Maker

JA Solar is one of the world's largest solar manufacturers by shipment volume, with a global track record spanning more than two decades. Proven scale, proven supply and panels installed in over 180 countries.

Tier 1 Bankability

Consistently rated Tier 1 by Bloomberg BNEF — the benchmark for bankability. Financial institutions trust JA Solar to honour warranties and deliver long-term performance.

DeepBlue 4.0 n-type TOPCon

The DeepBlue 4.0 series uses JA Solar's n-type TOPCon (Bycium+) cells for higher efficiency, lower degradation and better real-world output than conventional P-type PERC panels.

Australian Conditions

A favourable temperature coefficient means DeepBlue panels hold output in Australian heat, where lesser modules suffer larger efficiency losses on hot rooftops.

25-Year Product Warranty

A 25-year product warranty plus a 30-year performance warranty, backed by one of the most established solar manufacturers in the world. Long-term peace of mind for your system.

Proven Reliability

DeepBlue modules have been repeatedly recognised as a PVEL Top Performer in independent reliability testing — a strong, defensible signal of long-term durability.

Your concerns,
answered.

JA Solar is one of the world's largest solar manufacturers and a consistent Bloomberg Tier 1 brand, repeatedly named a PVEL Top Performer for reliability. Their DeepBlue 4.0 Pro modules use n-type TOPCon cells that perform strongly in Australian heat and high-UV conditions.
JA Solar's DeepBlue 4.0 Pro range carries a 25-year product warranty and a 30-year performance warranty, with a low annual degradation rate of around 0.3-0.4%. That means roughly 87% or more of rated output is still guaranteed at year 30.
DeepBlue 4.0 Pro uses JA Solar's n-type TOPCon (Bycium+) cell technology. Compared to older P-type PERC panels it delivers higher module efficiency (around 22-23%), lower degradation and a better temperature coefficient, so it holds output better on hot Australian rooftops.
