There is a risk of being struck by lightning. After all, the panels we installed are taller than others, have sharp corners and do not have lightning protection rods. It is better to connect the aluminum frame of the solar panels. the wall, steel bars or grounding, so that everything is secure. Lightning voltage will not penetrate the battery glass.
The main component of the solar charger is the solar cell. The photosensitivity of the solar cell is generally all visible light, whether it is sunlight or light. In fact, solar cells are just the common name for this device. The correct name for this period should be “photosensitive cells” or “photovoltaic cells”. According to the manufacturing materials, they are divided into silicon photovoltaic cells and selenium photovoltaic cells. The principle is the p effecthotoelectric. The reason it is called a photovoltaic cell means that the device generates electricity when exposed to light.
According to current regulations, city buildings and buildings in general are equipped with lightning rods and lightning generally does not strike them. If the solar water heater is struck by lightning, the electrical appliances in your home will be damaged and even injuries will be caused. To avoid this reason, when installing, do not install it higher than the surge protector on the roof. If it is higher than the building surge protector, you should use a 10mm diameter steel bar to connect the solar water heater bracket. to the building's lightning arrester (such as a parapet) (lightning protection device).
