- DNV audited the entire manufacturing process of the mono-facial HiKu7 and bifacial BiHiKu7 modules, including the incoming materials management, processes, quality control, etc.. DNV rated Canadian Solar at A+ for the HiKu7 and BiHiKu7 product lines.
- DNV noted that HiKu7 and BiHiKu7 modules possess industry-leading module efficiencies of up to 21.6%, a Pmax (Nominal Max. Power) temperature coefficient of -0.34%/℃.The LID and LeTID are controlled at 0.5% or less for the modules through improved manufacturing recipes and tighter material specifications. These indicate that the expected field performance of these modules would be better than that of typical commercial modules.
- DNV reviewed Canadian Solar’s reliability assurance program (including on-going reliability testing), component-level testing for service life, and mechanical testing. These testing include but not limited to thermal cycling with 400 cycles, damp heat with 2,000 hours, PID with 192 hours, double IEC testing standards. After these stringent testing, the above-mentioned modules show a power loss less than 2%.
- A solar power system with BiHiku7 will require fewer pieces of modules, thus fewer BOS (Balance of System) components, and an overall reduction in system CAPEX and LCOE.
Summary of DNV's Canadian Solar HiKu7 and BiHiKu7 Technology Review Report
DNV has completed a comprehensive technology review of the new Canadian Solar modules utilizing 210 mm cells. The review covered the company, modules, performance, reliability, system compatibility, field data, and an LCOE analysis.
