The right solution for your rooftop
The 280 Watt Monocrystalline Solar Panel is the ideal source and cost-effective solutions to covert your house from an energy dependant home to an energy producing location. Primarily used for residential purposes, the 280 watt panel can also be used in on-grid applications for commercial buildings.
Feature of the 280w monocrystalline solar PV panels
◇High cell’s efficiency mono silicon material for long term output stability and reliability.
◇Rigorous quality control to meet highest international standards.
◇Guaranteed positive output tolerance (0~+3%).
◇Tempered glass: anti-reflecting coating and high transmission rate glass increase the power output and mechanical strength of solar module.
◇Unique frame design with high mechanical strength for easy installation.
◇Using high quality EVA and TPT to prevent destroying and water.
◇EL tested solar modules; no hot-spot heating guaranteed.
◇Outstanding electrical performance under high temperature and low irradiance, cloudy weather conditions.
◇Pre-drilled holes on the back of the panel allow for fast mounting and securing.
◇Can be used for many different applications; ideal for residential and commercial rooftop systems; ground mount compatible; compatible with on or off-grid solar inverters.
◇10 years limited warranty on material and workmanship
◇12 years with 90% output, 25 years with 80% output warranty
