wholesale 1W Solar Panel (for Solar Garden Light)
The polycrystalline silicon and monocrystalline silicon solar panels produced by SUNNYBP. With EVA high-temperature laminated film on the rear surface, reiforced glass packing on the surface, alumimun alloy frame around it, cathode oxidation is adopted in treatment of the surface, corrosion-resistance frame, water-proof junction box, and overall exquisite technology.
*ISO9001, UL, CE, TUV Certification.
*Max power is less than 90% in 10 years and 80% in 25 years
*Grade A cell, efficiency >17%
Now the conversion rate solar panel market is still relatively low, generally only 16.5% of domestic Suntech can do 17 percent, it was done abroad by 25%.
Rensselaer Polytechnic Institute researchers in 2008 developed a new coating, which is covered in solar panels absorb sunlight to make the latter rate increased to 96.2%, while the ordinary solar panels absorb sunlight was only 70% or so.
The new coating technology solves two major problems, one solar panel to help absorb almost all of the solar spectrum, the second is to make solar panels absorb sunlight from a larger perspective, thereby improving the efficiency of the solar panels absorb sunlight .
Ordinary solar panels usually only absorb part of the solar spectrum, and usually only when the absorption of direct sunlight high working efficiency, so many solar installations are equipped with automatic adjustment system to ensure that the solar panels remain the most conducive to the absorption of the sun energy perspective.
