Main Components Of solar panel
A high efficiency (polysilicon more than 17.5%, monocrystalline
silicon more than 19%) imported class a solar energy package, to
ensure sufficient power generation of solar panels.
the glass surface, the thickness of 3.2MM, in the wavelength range
of the solar cell
spectral response within the transmission rate reaches above 97%,
the radiation ability of solar ultraviolet light glass colleagues,
light transmittance decreased.
A high quality EVA film with an anti UV agent, an antioxidant and a
curing agent thickness of 0.78MM is used as a sealant between solar
cells and glass, TPT.
On the back of the solar panels covering fluorine plastic film for
Baise, the sun has reflection function, because the efficiency of component
increased slightly, the fluorine plastic film first with aging,
resistant plate packaging material of solar cells required
corrosion resistance, air and other basic requirements.
The aluminum alloy frame has high strength and strong mechanical
Antioxidant, corrosion protection, good protective lamination
components, a certain sealing, supporting role.
1. Gird-connected power generation system
2. Off-grid power generation system
3. Building-integrated power generation facilities
Repair and maintenance
- Regularly check the panel for damage, ensure timely detection,
- Regularly check solar system cable and ground connection is good.
- Periodically check solar mounting structure have loose or broken
- Check and clean-up the covering around the panel and surface with
clean water and gauze, do not rinse with hard or corrosive solvents
- In case of gale, heavy rain, rainstorm, hail, heavy snow and so on,
measures should be taken to protect the solar cell module from
- After the gale, heavy rain, heavy snow or rainy season, immediately
check whether solar panel displace, controller and battery box
exist water, and thunderstorm after check whether the device is
working properly, its charge and discharge controller is damaged,
- Batteries used in matching with solar modules should strictly
accordance with the battery maintenance instructions and methods.
