Solar Energy:

The sun is a huge energy source. It emits about 3.8 × 10 MW of energy per second into space in the form of light radiation. One in 2.2 billion is projected to Earth. After sunlight is reflected and absorbed by the atmosphere, There are still 70 % transmission to the ground. Despite this, the solar energy received on Earth in one year is still as high as 1.8 × 10kW · H.

 

Since the formation of life on the earth, it has mainly survived by the heat and light provided by the sun. Since ancient times, humans have also learned to dry objects in the sun and as a way to preserve food, such as salt and salted fish. However, with the reduction of fossil fuels, it is intended to further develop solar energy. The use of solar energy includes passive use (photothermal conversion) and photoelectric conversion.

 

Solar power is an emerging source of renewable energy. In a broad sense, solar energy is a source of many energy on Earth, such as wind energy, chemical energy, potential energy of water, and so on.

SOLAR PHOTOVOLTAICS ( PV MODULE)

PV power generation is based on the principle of photovolt effect, using solar cells to directly convert sunlight into electricity. Whether it is used independently or connected to the grid, the photovoltaic power generation system mainly consists of three parts: solar panels(components), controllers, and inverters. They are mainly composed of electronic components but do not involve mechanical components.


Therefore, the photovoltaic power generation equipment is extremely refined, reliable and stable life is long, and the installation and maintenance is simple. In theory, photovoltaic power generation technology can be used in any situation that requires power supply, from spacecraft to domestic power sources, from large to megawatt power stations, to toys, and photovoltaic power sources can be ubiquitous.

Mono Solar Panel

Anti-reflective coating: AR used reduce the reflectivity enhance transmittance.

Tempered Glass: Low Iron and AR coating glass increase the power output and mechanical strength of solar module. Mechanical load ≥2400Pa , transmittance ≥91.6%

?  EVA: Transmittance ≥91% , Adhesive Capacity >85%

?  Cell: 17.9% of high efficiency solar cells to sure 15.7% module efficiency

Back sheet: Using higher quality back sheet to prevent destroying and water , it’s reflectivity ≥87%, peeling strength ≥ 40N/cm.

Aluminum Frame: Anodized aluminum alloy to effectively improve the corrosion resistance and strength.

 

Warranty:

 

10 year at 90% power output
25 years at 80% power output
