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.
