15W Monocrystalline Solar Panel PV Module for Home & Commercial Rooftop

Fifteen watts covers a little more ground than the smallest panel — enough to offset the standby drain of a controller, or to keep a modest battery healthy through a season of intermittent use. Where it fits best Maintaining batteries on seasonal equipment Small garden or path lighting with its own battery Offsetting standby drain on infrequently used vehicles Technical specifications Maximum Power (Pmax) 15 W Open Circuit Voltage (Voc) 21.84 V Short Circuit Current (Isc) 0.87 A Voltage at Pmax (Vmp) 18.2 V Current at Pmax (Imp) 0.82 A Module Efficiency 15.43 % Power Tolerance 0, +4.99W Maximum System Voltage 700 V DC Max Series Fuse Rating 10 A Module Type 182M01518 Solar Cells Mono crystalline 91*22.75mm (4*8Pcs) External Dimensions 405*240*17mm Weight 1.04 kg Front Glass 3.2 mm tempered glass Frame Aluminum Junction Box IP67 Output Cables Without cable Connector Without Compatible Mechanical Load Front Side Max. 5400Pa, Rear Side Max. 2400Pa Pmax Temperature Coefficient -0.350%/°C Voc Temperature Coefficient -0.270%/°C Isc Temperature Coefficient +0.048%/°C Package Dimensions 420*185*255mm Package Weight 11.4 kg Pieces per Package 10 Questions buyers ask Do I need a controller for 15 W? For long-term unattended charging, yes — a small PWM controller prevents overcharge. Some users connect directly for occasional top-ups, but it shortens battery life. Is a 1 kg panel durable? The tempered glass and aluminium frame construction is the same approach as the larger modules, jus Sold on IPV ESSA (https://ipvsolar.com/products/15w-405x240x17mm).
