n-type Bycium+ cells
16 busbars and multi-busbar half-cell construction. Lower temperature coefficient and less light-induced degradation than the p-type modules they replace.

Built out of parts
we can stand behind in 2050.
A solar system is a thirty-year commitment made in a single afternoon of purchasing decisions. We specify equipment that will still have a manufacturer behind it, a warranty path in New Zealand and a spare part available when something eventually fails.
JA Solar DeepBlue 4.0 Pro — JAM66D45 LB
n-type bifacial double-glass, 615 to 640 W, 132 half-cells in a 6 × 22 layout. This is the module we specify by default for commercial and rural work in New Zealand, and the one the figures across this site are modelled on.
Bifacial 80% ±5%
The rear face converts reflected light. On a light-coloured roof, gravel, sealed carpark or pasture the extra yield is measurable, not marketing.
Double glass, 2.0 mm each side
Anti-reflective coated front glass, heat-strengthened rear glass. No backsheet to yellow, crack or delaminate over the life of the array.
30-year linear warranty
1% degradation in year one, 0.4% per year thereafter — guaranteed at no less than 87.4% of nameplate output in year 30.
Performance at standard test conditions
Irradiance 1,000 W/m², cell temperature 25 °C, air mass 1.5G. Power tolerance 0 to +3%.

Performance with the rear face working
Bifacial nameplate irradiance: 1,000 W/m² front, 135 W/m² rear, cell temperature 25 °C, AM 1.5G. On the 640 W module that is 707 W — roughly 10% more from the same footprint.

Module specifications reproduced from the manufacturer’s datasheet (JA Solar, version Global-EN-20260610A). Specifications are subject to technical change; the manufacturer reserves the right of final interpretation.
Panels are the easy part.
Modules are a commodity with a long warranty. Almost every real-world failure we see is in the inverter, the mounting or the connections — so that is where the specification effort goes.
Inverters
String or central inverters compliant with AS/NZS 4777.2 and listed by the Electricity Authority as accepted for grid connection in New Zealand. We specify for local service support and parts availability, not just headline efficiency.
- Export limiting and zero-export control
- Per-string monitoring and DC arc-fault detection
- Battery-ready or hybrid where storage is on the roadmap
Mounting
Engineered systems certified for New Zealand wind zones, selected to suit the cladding: trapezoidal and corrugate steel, standing seam, tile, membrane, ground screw and driven pile, plus purpose-built canopy structures.
- Wind and snow loading assessed to AS/NZS 1170
- Non-penetrating fixings where the roof warranty requires it
- Anodised or marine-grade components for coastal sites
Protection and monitoring
DC isolation, surge protection at both ends, correctly rated AC protection, labelling to standard, and a monitoring platform registered in your name with alerting configured before we leave site.
- Generation metering separate from the retail meter
- Email or SMS alerting on underperformance
- Data export for your energy or sustainability reporting
