High efficiency 5W-300W PV price per watt solar panels

Characteristics of the raw materials

1.Cell: High efficiency (15.5%) of monocrystalline silicon solar cells encapsulated, ensure adequate power generation solar panels.

2. Glass: suede low iron tempered glass, in the wavelength range of solar spectral response (320-1100nm) light transmission rate of 91% or more, for more than 1200nm infrared light has a relatively high reflectivity. This glass also resistant to ultraviolet radiation from the sun, the light transmission rate did not decline.

3. EVA: made with ultraviolet resistant agent, antioxidant and curing agent of the thickness of 0.78 mm high quality EVA film as sealant of solar cell and and the connection between the glass, TPT agent.With high light transmittance and anti-aging ability.

4. TPT: solar cells on the back of the shroud - fluorine plastic film is white and reflection of the sun, so the efficiency of the component increased slightly, and because of its high infrared emissivity.Also can reduce the working temperature of components, but also to improve the efficiency of the component.Of course, the fluorine plastic first solar cell encapsulation materials required by the aging resistant, corrosion resistant, airtight etc. Basic requirements.

5. Border: used with high strength aluminum alloy frame, strong resistance to mechanical shocks.

6. Battery characteristics: a stable and efficient photoelectric conversion efficiency. Surface covered dark blue silicon nitride anti-reflection film, color uniform, attractive appearance. High-quality, high-efficiency solar cells ensure that the output power battery pack.
