Laboratories for electrical and fire safety (Class C fire rating); certified by T�V Rheinland as Class II equipment. compliant with the requirements of IEC 61215 and including: repetitive cycling between -40C and 85C at 85% relative humidity; simulated impact of 25mm (oneinch) hail at terminal velocity; a �€�damp heat�€� test, consisting of 1000 hours of exposure to 85C and 85% relative humidity; a �€�hot-spot�€� test, which determines a module's ability to tolerate localized shadowing 10-Watt Multicrystalline Photovoltaic Modules BP SX 10 The smallest of BP Solar's SX module series, BP SX 5 and BP SX 10 photovoltaic modules operate DC loads with small to moderate energy requirements. With 36 multicrystalline cells in series, they charge 12V batteries efficiently in virtually any climate. Typical commercial applications of these modules, which generate nominal maximum power of 4.5 watts and 10 watts respectively, include remote telemetry, instrumentation systems, security sensors, and signals.
