On March 5, the 20th China (Jinan) International Solar Energy Utilization Conference and Exhibition (referred to as "2025 Jinan Exhibition") was grandly opened at the Shandong International Convention and Exhibition Center.

Ultra-high efficiency and power: Higher conversion efficiency, with mass-produced power output exceeding 635W. Superior power generation capacity: Compared to traditional P-type PERC modules, N-type modules exhibit higher power generation in practical applications (such as low-light environments and high-temperature conditions). Lower temperature coefficient: Less power loss at high temperatures. Lower degradation rate: N-type cells typically exhibit lower initial and long-term power degradation.

The JA Solar N-type Bifacial Double Glass Module JAM72D42 LB 640/MR (part of the Deep Blue 4.0 Pro series) is a high-efficiency solar panel with a rated power output of 640 W and an efficiency of 22.9%. It features bifacial N-type TOPCon cells that generate power from both sides

Bifacial panels can also better benefit from solar trackers to follow the sun throughout the day. With tracking, the electricity generated has been shown by one study to increase by 27% over monofacial panels, and by 45% over fixed-tilt bifacial panels.4 Another study with similar results determined that bifacial panels on solar trackers decreased the cost of electricity by 16%.5

The 33% rule suggests that you can oversize a solar array by up to one-third more than the inverter's rated AC capacity. For example, a 5 kW solar inverter can often handle up to 6.65 kW of panels safely.

JA Solar is ushering in a new era of photovoltaic (PV) technology through innovations like its record-breaking TOPCon cells, the launch of advanced modules like DeepBlue 5.0, and a focus on high-efficiency, cost-effective solutions to accelerate the global transition to clean energy. This is supported by the company's expansion of its global manufacturing and sales networks, strategic partnerships, and commitment to developing all-scenario PV solutions for diverse installation environments worldwid
