The ability of solar panels to convert solar radiation into usable electricity is translated into their efficiency. It is the most commonly used standard by consumers when evaluating the quality of solar panels. Taking two photovoltaic modules as an example, under the same sunlight at the same time. The efficiency levels of these two solar panels are different; The one with higher efficiency generates more energy than the other.
In practical comparison, consider one solar panel with an efficiency of 24% and the other with an efficiency of 16%. Under the same conditions, a 24% efficiency solar panel can generate half the power as a 16% efficiency solar panel. Therefore, the efficiency of solar panels plays an important role in optimal energy utilization and cost savings.
There are various methods to improve the efficiency of installing a solar panel system. In short, some measures can be taken to maintain or increase the output level of solar modules. Before you delve into techniques to improve output, here are some factors that affect the efficiency of solar panels.
1. Hire professional solar installation personnel
When installing solar cell modules correctly, they can maximize the absorption of solar radiation. In this way, the solar panel will generate more electricity. When installing, direction and angle are the two main factors to consider. Under normal circumstances, solar cell modules can achieve optimal sunlight exposure at an angle of 18-36 degrees. For people in the northern hemisphere, solar panels should be located on a south facing slope. In the southern hemisphere, you should install solar panels on slopes facing north. The main idea is to maximize exposure to sunlight.
2. Cleaning
The components of solar panels are fixed, so there is no need for extensive maintenance. But dirt often accumulates on the surface, thereby reducing efficiency. Of course, when there is dirt on the surface, the absorption of sunlight will also decrease.
3. Use during peak periods of sunlight
Solar panels are typically generated from sunlight. In other words, it can only generate energy during the day. To achieve maximum effectiveness, try to use it during the midday period of the day, which will improve the efficiency of the solar panel. You can achieve this through the following methods. Ensure that all appliances, such as laptops, phones, and lighting fixtures, are fully charged when there is sunlight. Make sure to take out all solar energy devices during the day and fully charge them, so that they will be fully charged at night.
4. Use energy management software to monitor output
By using energy management software to monitor the output of solar panels, it is possible to notice when efficiency decreases and make timely adjustments.
By selecting efficient models of solar panels, using panels with high concentration photovoltaics, avoiding installation in cool places, having them installed by professionals, regularly cleaning them, and using energy management software to monitor output, the efficiency of solar panels can be effectively improved.
