1. The glass: it is made by super white fabric tempered glass, thickness is 3.2mm, light transmittance up to 91% under the solar batter spectral response range(320~1100nm), radiation of ultraviolet light resistant, light transmittance won’t decrease. module made by tempered glass can resistance the impact of diameter 25mm ice ball with 23M/s speed.
 
2. EVA: it made by thickness is 0.5mm high quality EVA membrane as encapsulant and glass. bridging agent between TPT. With high light transmittance and anti-aging ability.
 
The performance requirement of after curing EVA film:
 
Light transmittance should greater than 90%; degree of crosslinking should greater than 65-85%; peel strength(N/cm), glass/film should greater than 30%; TPT/film should greater than 15%; Temperature resistance requirement: high temperature 85℃, low temperature -40 ℃.
 
MPPT 100 | 50
 
Solar panel always mating with solar controller mppt type. MPPT is better than PWM type,it is a trend in the further future.
