The Grape Solar 280 Watt Polycrystalline PV Solar Panel uses high efficiency solar cells (aprrox. 18%) made from quality silicon material for high module conversion efficiency and long term output stability and reliability. Virtually maintenance free. High transmittance, low iron tempered glass for durability and enhanced impact resistance.
- Outstanding electrical performance under high temperature and weak light environments
- Positive power output tolerance from 0% to +3%
- Can withstand snow and wind loads greater than 50 lbs/ 2 ft.
- Unique frame design for easy installation
- Rigorous quality control to meet the highest international standards
- Positive and Negative leads equipped with MC4 connectors
- When charging 12V battery systems with this panel, an MPPT charge controller must be used for best performance.
