After installing solar photovoltaic modules, many friends look forward to accepting the “photovoltaic results”, but find that the results are different from what they expected. The photovoltaic modules do not meet the expected power generation capacity, which may cause many friends to make difficulties.

So why did photovoltaic modules fail to achieve the expected power generation? The reasons may include the following:

1. The light intensity may not be sufficient. The photovoltaic module can reach its maximum power only under standard conditions of light intensity of 1000W/m2, atmospheric quality of AM1.5, and temperature of 25 ℃.

2. The photovoltaic module itself has defects, resulting in power loss due to system failures.

3. The power of the photovoltaic module is too small to match the appropriate power of the module.

4. The operating temperature of photovoltaic modules has a significant impact on their output power, and excessive operating temperature can lead to power loss.

5. Failure to clean up dust, fallen leaves, and other debris on the surface of the photovoltaic module in a timely manner, resulting in reduced illumination received by the module, and ultimately affecting the module’s power generation.

6. Failure to timely adjust the component position according to the actual situation.

All of these reasons can affect the power generation of photovoltaic modules. In order to address the problem that the power generation of photovoltaic modules is lower than expected, we provide the following targeted solutions:

First, when purchasing a photovoltaic system, try to select photovoltaic modules with good quality and high reliability as much as possible to reduce the failure rate and ensure the maximum output power of the module.

Secondly, when considering photovoltaic modules, attention should be paid to the power of the modules. If more power generation is required, the corresponding higher power modules should be matched.

Third, attention should be paid to controlling and maintaining the operating temperature of photovoltaic modules, and attention should be paid to ventilation and heat dissipation of photovoltaic modules to avoid affecting efficiency due to excessive operating temperature of the modules.

Fourth, regularly check the cleanliness of the component surface (once per month), and regularly clean the component. During cleaning, pay attention to the cleanliness of the component surface to avoid residual dirt and blocking. The cleaning time should be selected as the time when there is no sunlight in the morning and evening.

Fifth, after finding the appropriate installation direction and angle for the photovoltaic module and installing it correctly, it is also necessary for everyone to use a solar irradiance meter to test the irradiance of the current module location, and repeatedly adjust the angle until the location with the highest solar irradiance is found.

At the same time, attention should also be paid to using this method in different seasons, and the position and angle of the components should be adjusted in a timely manner according to the actual situation, in order to ensure that the power generation of the components is maximized.
