Poly solar system is a power generation system of a concentrating solar power plant. It uses mirrors or lenses, and uses optical principles to gather a large area of sunlight into a relatively small light-collecting area, so that the solar energy is concentrated.

The light-collecting area on the generator is illuminated by sunlight and the temperature rises. Converting solar energy into heat energy, the heat energy is driven by a heat engine (usually a steam turbine engine) to drive a generator, thereby generating electricity.

poly solar panels

Wholesale poly solar panels

Schutten solar has professional producing experience of mono and poly solar system for more than a decade,we has become a company with mature technology and management system, our products with the certificates of ISO, CE IEC CE CGC etc. and production capacity is 3 GW per year .

High Efficiency

Higher module conversion efficiency benefit from half cell structure(low resistance characteristic).

Multi busbar technology

Better light utilization and current collection capabilities, effectively improving product power output and reliability.

Longer service life

Excellent double-sided warranty promises a 30-year power warranty of 0.45% linear power attenuation.

Severe Weather Resilience

Certified to withstand:Wind load(2400 pascal) and snow load(5400 pascal).

Double-sided power generation

The double-sided power generation gain increases with the light received on the back side, up to 25%, which significantly reduces the LCOE.
