PV Module Knowledge BaseFrom materials to failure, one module at a time

Practical module engineering from a team with 10+ years in PV R&D, manufacturing, reliability and certification

Materials (BOM)

Glass, encapsulants, backsheets, ribbons, flux, junction boxes. One profile per material - function, key specs, test methods, typical failures.

Layouts, half-cut cells, multi-busbar, glass-glass, lightweight and flexible modules, and the trade-offs behind each choice.

Stringing, lamination, framing, EL and IV testing. How process windows relate to defects.

TC, DH, HF, PID, UV, mechanical load - broken down as test condition, failure signature and mechanism.

Cracks, snail trails, delamination, yellowing, hot spots, PID. Start from what you see in the field.

Clause-by-clause notes on IEC 61215 / 61730 and UL, plus lessons from real certification projects.

Factory audits, incoming inspection and quality-risk screening, from inside the Chinese supply chain.

Chinese-English PV module terminology, so both sides of the supply chain mean the same thing.
