Information

A complete solar photo-voltaic system consists of solar cells, solar controllers and batteries (groups).

 

Solar panel:

        The solar panel is the core part of the solar photo-voltaic system. The function of the solar panel is convert the sun's light energy into electrical energy, then output the direct current into the battery.

        Solar panel is one of the most important components in the photo-voltaic system. Its conversion rate and service life are important factors that determine whether a solar cell has value in use. 

 

Composition of solar panels:

        Cells: High-efficiency (above 16.5%) mono solar cells are used for encapsulation to ensure sufficient power generation of solar panels.

 

 

        Glass: The use of low iron tempered suede glass (also known as white glass), thickness of 3.2mm, in the solar cell spectral response wavelength range (320-1100nm) light transmission rate of more than 91%, for more than 1200 nm of infrared light has a high reflectivity.The glass is also resistant to radiation from the sun's ultraviolet light, and the transmission rate does not decrease.
 
        EVA: A high-quality EVA membrane layer with an anti-UV agent, antioxidant and curing agent with a thickness of 0.78mm is used as a sealant for solar cells and a connecting agent with glass and TPT. It has high light transmission and anti-aging ability.
 
        TPT: The back cover of the solar cell-the fluoroplastic film is white, which reflects the sunlight, so it slightly improves the efficiency of the module, and because of its high infrared emission rate, it can also reduce the operating temperature of the module. Conducive to improving the efficiency of the component.
 
        Border: The aluminum alloy frame used has high strength and strong resistance to mechanical impact. It is also the most valuable part of solar photovoltaic systems. The effect is to convert the sun's radiant capacity into electrical energy, either to be stored in a battery or to push the load to work.
 
Controller:
        The solar controller is composed of a dedicated processor CPU, electronic components, a display, and a switching power tube.
 
 
Battery:
        The role of the battery is to store the electrical energy emitted by the solar panel when it is lit and release it when needed.
 
Inverter:
        The direct output of solar energy is generally 12VDC, 24VDC, 48VDC. In order to supply electricity to 220VAC appliances, DC-AC inverters are required to convert THE DC power generated by the solar photovoltaic system into AC power.
 
Traditional fuel energy is decreasing every day, and at the same time, about 2 billion people around the world do not have a normal energy supply.
 
At this time, people look to renewable energy, hope that renewable energy can change the human energy structure, maintain long-term sustainable development.
 
Among them, solar energy has become the focus of people's attention because of its unique advantages. Rich solar radiation energy, is inexhaustible, pollution-free, low price energy.
 
Estlux has never forgotten the begining, insisting on making the highest quality solar panels at the most reasonable price, and Eastlux is your most trusted partner.
