(1) Waterproof, anti-mite, and windproof.
Generally, the solar panel is packaged in tempered glass, and the outer frame is packaged in aluminum alloy, which can effectively resist the hail attack。 The installation is fixed by a metal bracket, and can resist the wind of 10 or above。
(2) Sun protection and antifreeze。
Generally, there are ventilation and heat dissipation windows to facilitate heat dissipation of the battery. For particularly cold winter areas, the battery uses an anti-coagulation gel battery.
(3) Control protection
In order to extend the service life of the battery and the battery to a greater extent, the anti-back charge, over charge, and over discharge protection circuits are generally controlled to avoid premature aging of the battery board and the battery.
(4) Parts selection
Due to the different environment in which solar photovoltaic products are used, the temperature difference is large, so the operating temperature range of the parts is required to be wide.
The solar cell power generation system has no moving parts, is not easily damaged, and is easy to maintain。 However, regular maintenance is also required, otherwise it may affect normal use or even shorten the service life。
Generally speaking, the square angle of the solar panel should exceed 30 degrees。 All dust can be cleaned by rainwater。 In large areas of wind and sand, dust should be removed frequently to keep the surface of the square clean, so as not to affect the power generation。 Try to remove dust when cleaning。 If necessary, clean it with water and then dry it with a tube rag。 Do not rinse with corrosive solvents or hard objects。 Regularly check the tightness of all installed parts。 In case of abnormal weather such as hail, squally wind and heavy rain, protective measures should be taken in time。 Always check the charge and discharge of the battery, and check the electrode or wiring for corrosion or poor contact。
In some simple systems, the power consumption should be controlled according to the energy storage condition to prevent the battery from being damaged due to over-discharge. It was found that there should be a situation that should be checked and repaired immediately.
