Solar panel operation and maintenance, photovoltaic power station cooling and special weather processing methods Jan 17, 2019

Have you really learned how to assemble solar panels into photovoltaic power plants for heat dissipation and special weather conditions?

 

First, keep ventilation

 

Regardless of the components or the inverter, the distribution box should be kept ventilated to ensure air circulation. For the components of the rooftop photovoltaic power station, it is important not to arrange the arrangement of the photovoltaic power plant components reasonably for the purpose of generating more power, causing the components and components to block each other, and affecting the heat dissipation and ventilation, resulting in low power generation.

 

So, if someone is fooling you to install a few more components on a limited area, be careful. A reliable brand owner will provide the most reasonable design based on the roof of your home before the installation, maximizing the amount of power generated, rather than letting you have more components.

 

For the owners of photovoltaic agricultural greenhouses, ventilation should be considered. Ventilation can be set in the blind area of the back of the greenhouse, so as not to affect the crop growth condition, it is suitable to ensure the temperature of the photovoltaic power plant operating environment to the greatest extent.

 

Second, timely cleaning of debris around the photovoltaic power station

 

To avoid affecting the heat dissipation of the photovoltaic power station, it is necessary to ensure that the photovoltaic modules, inverters, and distribution boxes are wide open, and if there are debris accumulation, clean up in time.

 

Third, set up a parasol for the inverter distribution box

 

Household inverters are generally IP65 rated, with a certain degree of wind, dust and water resistance. However, when the inverter and distribution box work, they must also dissipate heat, so install the inverter and distribution box. It is best to install it in a place where it is protected from rain and rain. If it must be installed in the open air, then make a simple awning for the inverter and distribution box to prevent direct sunlight. Avoid overheating the inverter and distribution box and affect the amount of power generated.

 

4. What should I do if I encounter bad weather?

 

1), lightning strike

 

If you want to protect against lightning, the most effective and widely used method is to connect the metal parts of electrical equipment to the earth. The connection part is welded or gas-welded. Soldering cannot be used. If the welding cannot be done at the site, riveting or bolting can be used. To ensure the contact surface of 10cm2 or more, the buried depth of the grounding body is preferably 0.5~0.8m. Remember to backfill the soil must be solidified.

 

2), rain

 

If your roof is a sloping roof, don't worry at all. If your home is a flat roof, it is best to consider the drainage problem when designing and installing the PV power plant. Avoid when the rainfall is too large, because the flat roof bracket is installed relatively low, so that the photovoltaic modules are soaked by rain.

 

During the inspection after the rain, do not directly touch the connection between the inverter, the PV module and the power supply cable by hand, and bring rubber gloves and rubber boots.

 

3), ice

 

From qualified PV power plants purchased by large manufacturers, PV modules are tested by hail at 23m/s, so hail will not affect PV modules.

 

However, after the hail, daily inspections are indispensable. If the photovoltaic power station has a significant drop in power generation or other abnormal conditions after the hail, the owner must notify the factory after-sales personnel to conduct the test.

 

4), regular inspection is essential

 

After the PV power station is built, the operation and maintenance can't be too sloppy. Especially in the summer, it is best to conduct regular inspections to ensure that the PV power station has good heat dissipation, air circulation, and timely removal of weeds and obstructions that affect heat dissipation. Only in this way can the power generation and operation of the photovoltaic power station be guaranteed.
