Energy & Environment sourcing FAQ
What certifications should solar panels have?
IEC 61215 covers the PV module performance standard; IEC 61730 covers safety. For the UK market, MCS certification is required for grid-connected installations. US requires UL 1703 or IEC 61215. Top-tier manufacturers also hold TÜV, PV CYCLE, and ISO 9001 certifications. Always match the cell type (mono vs poly vs bifacial) to your application.
How do I assess battery storage system quality?
Look for UN38.3 battery transport safety certification, IEC 62619 for safety requirements, and UL 9540 for energy storage systems (US). Cycle life specifications should be independently verified. Top BMS (Battery Management System) capabilities and thermal management design significantly affect longevity and safety.
Which countries lead in solar panel manufacturing?
China produces over 80% of global solar panels, led by tier-1 manufacturers (Longi, JA Solar, Trina, Canadian Solar). Germany has strong inverter manufacturers (SMA, Fronius). South Korea excels in battery cells (Samsung SDI, LG Energy). For buyers concerned about supply chain risk, check Bloomberg NEF tier-1 manufacturer lists.
What should I check when sourcing water treatment equipment?
Verify NSF/ANSI 61 certification for drinking water contact components (US standard). WHO guidelines compliance for international humanitarian projects. CE marking for EU. Request treatment capacity specifications, energy consumption data, and reference installations. Membrane-based systems (RO, UF) should have certified flux rates.
