Chinese solar manufacturer JA Solar has unveiled the world’s most powerful PV module: the Jumbo solar panel with a power output the company says tops 800 W of output.
The 240-cell panel – unveiled at the SNEC PV Power Expo trade show in Shanghai – has quadruple layouts of PERC cells and features a triple-cut cell design with 11 busbars on 210mm wafers. It is the most powerful and the biggest, heaviest device on the market, with dimensions of 2,219×1,765x40mm and weighs in at 43.5kg. By comparison, a 585 W panel unveiled by a competitor this year measures 2,411×1,134x35mm and weighs 31.1kg.
According to the JA Solar panel’s product sheet, the JAM80S40 785-810 HRM module series is available in six versions which offer power outputs of 785-810 W and efficiencies ranging from 20.1 to 20.8%.
Open circuit voltage is reportedly 81.90-82.68 V and maximum power voltage ranges from 68.39-69.84 V, depending on the size. Short circuit current is said to range between 12.50 and 12.20 ampere and power tolerance is 0%/+5%.
The operating ambient temperature ranges from -40 to 85 degrees Celsius, according to the manufacturer, and maximum system voltage is 1,500 V. The junction box has a reported IP 68 rating.
JA Solar says it offers a 12-year product warranty and 25-year power output guarantee. Annual linear degradation over 25 years is indicated at 0.55% while degradation for the first year of the panel’s lifetime is capped at 1.5%.
The manufacturer said 27 modules can be loaded on a pallet. For comparison, 31 of the 580 W panels offered by another competitor can be stowed on one pallet.
The JA Solar module is yet to enter mass production.

Big and powerful, ready for large solar farms, where you need fewer series panels for the on-grid inverters. Just 4 of these, in series, will meet the voltage requirments of the grid tied inverters today or could be micro invertered each to full voltage on grid supply. Single phase or 3 phase, these monsters would be ready to take us to the 21st century of renewable energy when coupled with energy storage. Now if we could get all those coal workers out of the danderouse mines and into installing these above the old coal pits with better wages and no black lung. The International Brotherhood of Electrical Workers (IBEW) Could help them in the transition with training and Union Cards.
Impressive Efficiency Values…. but not by “mine is bigger than yours” as weight is now 40+kg….
Imagine trying to handle this on sloping Residential Roofs ….. have you ever seen Baggage Handlers handling 25/35kg Suitcases… standing on the ground…. you get the idea….!!!!
For larger projects…. where Cranes etc. can be used…. don’t we need much larger assemblies of PV Panels…. rather than single modules…. ????
Conversions for the metrically challenged:
2,219×1,765x40mm == 87.36in x 69.5in == 7.28ft x 5.8ft
43.5kg == 96lbs
definitely a big panel
