1. Photovoltaic module dedusting

Small photovoltaic power stations adopt manual cleaning methods, usually with mops, rubber scrapers or soft rags for cleaning. The manual cleaning of large and medium-sized photovoltaic power plants is difficult, and mechanical cleaning is generally adopted. High-pressure water gun cleaning, water vapor mixture formed after pressurization, will clean the surface dust of photovoltaic panel, cleaning effect is better, so it is widely used in many photovoltaic power plants. In addition, there are mechanical dust removal technology, such as the use of mechanized brushes combined with sprinkler flushing photovoltaic panel automatic dust removal device, relying on mechanical force to remove dust.

2. Photovoltaic modules should avoid shading

Before the construction of photovoltaic power plants, we must do a good job of pre-exploration to determine whether there will be shelter for surrounding high-voltage lines, railings, vegetation and buildings (also counted as planned buildings).

Some people install fences for power stations, in order to drive birds to set up a rod to drive birds, it was a good move, but it played a counterproductive role. Others lack knowledge of photovoltaic operation and maintenance, and incorrect practices such as drying clothes in photovoltaic modules will invisibly block the power plant.

3. Photovoltaic modules should avoid hot spot effect

Before construction, technical handover should be done well, and random inspection of engineering quality should be strengthened during construction.

The measures in the module production section include: controlling the reverse current of the battery, controlling the impurities in the battery, and adopting parallel diode protection for the module.

The measures at the application end are: using the battery (or module) with good performance consistency, ensuring that the module is not blocked when installed, cleaning and cleaning in time when there is dirt on it, and so on, so that the photovoltaic system can maintain a good power output.
