General solar panels are sealed with toughened glass, and the outer frame is sealed with aluminum alloy, which can effectively resist hail attacks. The installation is fixed with metal supports, and can resist winds of more than 10 levels.
Sunscreen, anti-freezing
Generally, there are ventilation and heat dissipation Windows to facilitate the heat dissipation of batteries. For especially cold areas in winter, the battery uses anti-solidification colloidal battery.
Control protection
In order to maximize the service life of the panel and battery, there are generally anti-reverse charge, over-charge, over-discharge protection circuit control, to avoid damage to the panel and battery premature aging.
Parts to choose
Due to the different use environment of solar photovoltaic products, the temperature difference is large, so the working temperature range of parts is required to be wide.
maintenance
Solar cell power generation system has no moving parts, is not easy to damage, its maintenance is very easy. But also need to do regular maintenance, otherwise it may affect the normal use, or even shorten the service life.
Generally speaking, solar panel phalanx inclination Angle should be more than 30 degrees, all dust can be washed by rain and self-cleaning, in areas with large sand, dust should be removed frequently to keep the phalanx surface clean, so as not to affect the power generation. When cleaning, dust can be wiped off. When conditions are available, clean water can be used to clean, and then dry with a clean cloth. Do not use corrosive solvents or hard objects to wash and wipe. Check the tightness of all installed parts periodically. In case of hail, wind, rainstorm and other abnormal weather, protective measures should be taken in time. Check the charge and discharge status of the battery regularly, and observe whether the electrode or cable connection is corroded or in bad contact.
