3 Ways to Increase Photovoltaic Power Generation

1. Regular inspection

Inspection of component temperature, tributary terminal, distribution box, current and voltage detection, grounding resistance test, etc. are detected by equipment. In addition, it is also necessary to regularly check the cleanliness of the module surface, the appearance of the module, whether the smell is abnormal, the grounding of the module, the temperature of the module, and the consistency of the modules and strings. In the second category, check the connection of the bracket members supporting the photovoltaic accessories, the corrosion resistance of the bracket members supporting the photovoltaic modules and the grounding parts, whether the bolts are fixed firmly, whether the connection between the bracket and the grounding system is reliable, and whether the base and the foundation are firmly connected. Three types of string inverter conditions, such as equipment appearance, operating sound or vibration, warning signs, grounding conditions, external components (cooling fans, screens, LED lights, buttons) conditions, DC string wiring, AC wiring and communication situation, whether the operation records are correct, etc. Four types of power cable inspection. For example, there should be no expansion or cracking of the cable, the plugging of the cable perforation position, ensure that the cover plate of the cable trench or cable well is intact, and ensure that the bolts between the bridge and the bracket and the bolts of the bridge connecting plate are well fixed. Five types of AC distribution box inspection. Such as AC circuit breaker, appearance, terminal connection, insulation resistance, lightning arrester, etc.

2. Frequent cleaning

Cleaning Dust: Dust blocking will reduce power generation. After clearing the photovoltaic panels, the power generation is increased by 5-20%.

Cleaning oil pollution: After cleaning, the power generation is increased by 5-40%.

Cleaning debris: bird droppings, debris, close attachments, etc. will block the photovoltaic panel and reduce the solar energy conversion rate, so it should be cleaned in time.

3. Multi-innovation

For example, the use of cleaning robots can only clean photovoltaic modules to increase power generation.

For example, the use of drones and video monitoring equipment and software can automatically inspect photovoltaic power plants, and real-time monitoring and fault location of hot spots or components with abnormal temperature through real-time transmission of images. The occurrence of abnormal situations can be checked through the monitoring screen, which can effectively prevent the occurrence of fire or theft.
