How will thunderstorms affect photovoltaic equipment?

So what damage will thunderstorms cause to photovoltaic power generation equipment?

1. Thunderstorms can cause damage to solar cell modules.

Solar photovoltaic panels are not only the core part of photovoltaic power generation equipment, but also the most valuable part of photovoltaic power generation equipment. Converting the radiant energy of the sun into electrical energy is its main function. However, it needs to be arranged in an open field, so it is extremely vulnerable to lightning strikes and the entire system is paralyzed.

2. Thunderstorms will damage the photovoltaic controller

The photovoltaic controller controls the working state of the entire system and protects the battery from overcharging and overdischarging.

When the system is damaged by a thunderstorm or overvoltage, the charging system will be charged all the time, and the discharging system will not be discharged, or the charging system will not be charged, and the discharging system will be in a discharging state, which will cause the equipment to be unusable at light level, or cause the battery to explode and cause the entire battery to explode. damage to the system and casualties.

3. Thunderstorms will damage the battery.

Solar photovoltaic power generation equipment usually uses lead-acid batteries, nickel-metal hydride batteries, nickel-cadmium batteries or lithium batteries to store electrical energy. When a thunderstorm occurs, the overvoltage invades the battery, which will damage the battery and shorten the battery life cycle, or cause the battery to explode. Cause more serious system failures and casualties.

4. Thunderstorms will damage the inverter.

If you want to convert the DC power from the solar photovoltaic power generation equipment into AC power, you need to use a dc-ac inverter. Once the inverter is damaged, there will be no voltage input to the user's load, or the inverter cannot invert the voltage, resulting in the DC voltage generated by the solar photovoltaic panel being directly used by the load. Once the voltage of the solar photovoltaic panel is too high, it will directly burn the electrical equipment. .
