What is JA Solar and what does it contribute to your photovoltaic installation?
The JA Solar collection brings together high-efficiency photovoltaic modules aimed at residential, commercial, and industrial projects. It includes next-generation monocrystalline PERC panels and bifacial versions for ground-mounted or suitable rooftop installations, with 108/132/144 cell formats and robust frames for extended service life. Its approach focuses on maximizing production per surface area, facilitating string design, and ensuring reliable integration with modern inverters.
Advantages and limitations
- High power density: typical outputs from ~450 W up to more than 700 W, reducing the number of panels and structure per kWp.
- Stable performance: competitive thermal coefficients and industrial quality control.
- Versatility: 108/132/144 cell formats to adapt to different surfaces and wide MPPT windows.
- Bifaciality (in specific models) that adds energy gain in installations with good albedo.
- Limitations: high-current modules require compatible inverters and strings; always check Voc/Isc and the inverter's MPPT window.
Applications
- Residential self-consumption on pitched roofs with monocrystalline panels due to their good power/size ratio.
- Commercial and industrial with long strings and structures on ground or flat roof.
- Plants and canopies where bifacial panels provide gain by reflection.
- Bulk purchases with packs and pallets to optimize logistics and cost per W.
How to choose your JA Solar panel
- Power and size: choose the power that best fits geometrically; more W per panel reduces the number of units.
- Voc and Isc: size the number of modules per string considering the Voc at minimum temperature and the Isc at maximum irradiance.
- Inverter MPPT: check the tracking voltage range and current per input; use High Current models if appropriate.
- Mono vs. bifacial: bifacial performs better with high albedo (light gravel, light ground, or elevated structure); on a conventional roof, monofacial is the simplest option.
- Compatibility: add optimizers if there are shadows or mixed orientations.
Indicative specifications (depending on model)
| Nominal power | ≈ 450–710 W |
| Cell type | Mono PERC (formats 108/132/144 cells) |
| Module efficiency | ≈ 20–22.5 % |
| Open-circuit voltage (Voc) | See datasheet; consider Voc at -10 °C / -25 °C for strings |
| Short-circuit current (Isc) | See datasheet; check inverter input limit |
| Typical warranties | Product and linear performance (depending on series) |
Best practices
- Calculate strings with thermal (Voc) and current (Isc) margin relative to inverter and DC protection limits.
- Coordinate DC protections and AC protections (isolation and SPD).
- Use coplanar structures or for ground/flat roof with certified anchors.
- Plan compatible wiring and connectors; maintain recommended bending radii and tightening torques.
