JA Solar photovoltaic module

• JA Solar is a major global manufacturer of solar cells and PV modules: wafers → cells → modules.

Specifications

• <p> Rated Maximum Power (Pmax)</p><p> Panels from ~ 325 Wp up to ~ 550 Wp (or more) depending on model. &nbsp;</p><p> Module Efficiency (η)</p><p> ~ 19% to ~ 21.5% for many modern JA Solar modules. &nbsp;</p><p> Open-Circuit Voltage (Voc)</p><p> Roughly 40 V to 50 V depending on panel design. E.g. a 550 W panel shows Voc ~ 49.9 V. &nbsp;</p><p> Voltage at Maximum Power (Vmp)</p><p> ~ 34 V to ~ 42 V, depending on model; e.g. some high‑power panels list ~ 41.9 V. &nbsp;</p><p> Short-Circuit Current (Isc)</p><p> ~ 9 A to ~ 14 A depending on module size/ design. &nbsp;</p><p> Current at Maximum Power (Imp)</p><p> Corresponding to Vmp — e.g. around 9–13 A depending on panel. &nbsp;</p><p> Power Tolerance</p><p> Often around 0 W to +5 W; some variation depending on batch. &nbsp;</p><p> Maximum System Voltage</p><p> Commonly 1500 V (suitable for large arrays or string configurations) in many JA Solar modules. &nbsp;</p><p> Temperature Coefficient (Pmax)</p><p> Around −0.34%/°C to −0.36%/°C — indicates loss of output per °C above 25°C. &nbsp;</p><p> Operating Temperature Range</p><p> Many modules rated for roughly −40 °C to +85 °C (so they can handle harsh environmental conditions) &nbsp;</p><p> Mechanical / Physical Specs</p><p> Typical large 550 W‑class module: dimensions around 2278 × 1134 × 35 mm, weight ~ 28–32 kg. &nbsp;</p><p> Durability &amp; Load Ratings</p><p> Many JA Solar modules are designed for high mechanical loads — front‑glass + frame able to withstand wind and other stresses in array/installation. &nbsp;</p><p> Warranty / Performance Guarantee</p><p> Typical product warranty ~ 12 years; long‑term power output warranty (e.g. guaranteeing a certain % of rated output over 25+ years) depending on model. &nbsp;</p><p> </p>
