PWSOLAR Start Massive Supply 605W to 670W Modules from 2021

PWSOLAR Launches Mass Supply of 605W–670W High-Power Modules from 2021

PWSOLAR scales manufacturing to deliver 600W+ utility-grade modules for global EPC, distributor and developer supply chains

PWSOLAR has officially commenced mass production and supply of high-power modules in the 605W to 670W range, marking a significant step in our capacity to serve utility-scale solar projects globally. This module range employs N-type TOPCon cell technology — delivering industry-leading efficiency, superior bifacial gain, and lower degradation compared to conventional PERC modules.

1. Why 600W+ Modules Are Reshaping the Utility Solar Market

• Fewer modules, lower BOS cost: Each 670W module replaces 1.4× a 480W module — reducing racking, wiring, and labor costs by 15-25% for large ground-mount systems
• Higher string density: Compatible with 1500V string inverters — enabling longer strings and reducing combiner box count on utility projects
• Lower LCOE: Combined module efficiency gain and BOS savings reduce levelized cost of electricity by $2-4/MWh versus prior generation modules
• Global utility demand: 600W+ modules are now the standard specification for utility-scale procurement in the EU, Middle East, Australia, and South America

2. N-Type TOPCon Technology Advantages

• No LID/LeTID: N-type cells eliminate light-induced degradation present in PERC — delivering the rated power output from Day 1 and superior long-term yield
• Better temperature coefficient: -0.34%/°C vs -0.37%/°C for PERC — maintains higher output in hot climates (Middle East, South Asia, Latin America)
• Bifacial gain: Up to 30% additional energy from rear-side generation in ground-mount applications with bright albedo surfaces
• Bankability: N-type modules carry 30-year linear power warranties — matching the project finance horizon of utility-scale PPAs globally

3. PWSOLAR's Manufacturing and Supply Capability

• Dedicated N-Type production lines: PWSOLAR operates dedicated TOPCon cell and module production lines with automated quality inspection at every stage
• SPC quality control: Statistical process control applied to cell sorting, lamination, and EL inspection — ensuring consistent Pmin binning across large volume orders
• Flexible logistics: FOB/CIF/DAP supply terms from Chinese port to global project sites — Rotterdam, Dubai, Los Angeles, Sydney, Buenos Aires
• OEM/ODM capability: Custom branding, special mounting hole patterns, and regional compliance variants available for distributor and developer partnerships
