Why this list is short.
580 W and up, nothing smaller
Every module we quote is n-type and rated 580 W or more, with flagships above 700 W from JA Solar, LONGi, Jinko, Qcells, Sky Japan and Sonnex. Fewer panels per kilowatt means less racking, less cable and less roof.
Certified, and on the approved list
IEC 61215 and 61730 on modules, IEC 62852 on connectors, IEC 61643-11 and UL 1449 on surge protection. Equipment also has to appear on SREDA's approved product list, or your net metering application is returned.
Specified for this climate
1500V DC throughout, IP65 to IP68 enclosures, double insulation and direct burial rated cable. Dhaka humidity and monsoon water ingress kill more systems here than irradiance ever limits.
Monitored, not assumed
Pyranometers, Class 0.5s metering, data logging and zero-export control. A plant that quietly underperforms costs more over 25 years than one that fails outright, because nobody notices.
