270 WATT POLYCRYSTALLINE PHOTOVOLTAIC MODULE
EMC Solar polycrystalline modules are ideal for large-scale deployment in even the most challenging conditions of utility. 
Manufactured from polycrystalline-cast blocks of silicon, each cell is coated with an anti-reflective substance which increases conversion efficiency for minimal energy losses. Through an advanced cell texturing and isolation process, power output is also maximized which improves performance at low levels of irradiance.
FEATURES
Polycrystalline cells tend to be less expensive and only slightly less efficient per cell area compared to monocrystalline modules. Each module is built to withstand high wind pressure, large snow loads and extreme temperature variations. Unique design on drainage holes and rigid construction prevents the module frame from deforming or breaking in freezing weather or other harsh weather.
This module is recommended for on-grid utility and commercial systems, and off-grid ground mounted systems.
