Energy Technology offers the SUNTECH 270 W polycrystalline solar panel. The STP270-24/Vb -1 PV panel can be utilized for powering on grid utility and commercial systems and off grid ground mounted systems. The BSF (back surface field) structure of this module is improved and given anti-reflective coating to improve the conversion efficiency of the module. The advanced cell texturing and isolation process incorporated in the module improves the irradiance functioning and increases the output.
The SUNTECH 270 W solar panel offered by Energy Technology incorporates a rigidly constructed frame design with drainage holes to prevent deformation or breaking due to weather vagaries.
