What's the main features of crystalline silicon solar cell?

1.Crystalline silicon solar cell has a steady photovoltaic efficiency.
2.SIN/TiO2 as anti-reflection coating or Epoxy AB resin coating, shows uniform dark blue color.
3.Advanced gettering and passivation processes achieve high performance for solar cell.
4.Advanced screen printing technique ensure high-precision grid pattern which is easy to align for tabbing and string machine.
5.Cell appearance remains good flatness and thus is easy to cut.

Fixing notice item of solar PV modules:
1.The best way to confirm the azimuth is to use the compass, and notice that there must not be the adumbral things such as the high buildings and trees etc for the whole day.
2.Carefully check if the fixing screws and azimuth stringers are solid, all the screw connection poles are should be tighten, no loosen.
3.If the solar PV modules are fixed on the roof, the measure for fireproofing must be adopted. If the modules are fixed on high places, the lightning arrester must be set up. And sometimes the device for dispersing the birds is necessary.
4.When fixing under the sun, no touch the anode and cathode of the solar PV modules (especially the azimuth) at the same time to avoid being tip-and-run. If need, firstly use the opaque materials to cover the solar PV modules and then connect and assemble.
5.When fixing the solar PV modules, it’s necessary to carefully take them, no collision and hit to avoid being destroyed.
6.Notice that the polarity of each modules, prevent from reverse-connection.
7.The accumulator box must be keep ventilated, dry and clear. In winter, the measure for keeping it warm should be adopted.
　

How to maintenance the solar PV modules?
Answer: It’s very easy the maintenance because the solar PV modules is hard to be destroyed. However it’s necessary to termly maintenance, otherwise its normally using will be possibly affected, even shorten the lifetime.
Generally, the angle of the solar battery panel should be over 30 degree, the dust could be washed out by the rainwater and keep clean. In the area with the strong sand blown by the wind, the dust should often be cleaned to keep the surface of the azimuth clean.
When cleaning, wipe the dust, if the condition is well, use the water to clean, and then wipe up with the dry rag. No wipe with the caustic impregnant and hard things. Termly check the tightness condition of fixed modules. When suffering the bad weather such as hail, gustiness and rainstorm etc, the protection measure should be adopted. Often check the storage battery’s charge and release charge conditions, momentarily observe if the electricity poles and the connection are eroded or in bad connecting condition.
In some simple system, according to the storage energy condition, you should control the electricity’s use to avoid being destroyed because of over discharge. If any singular instance is found, you should immediately check and maintenance.
