How to calculate the efficiency of a solar panel? Here is how the efficiency of a solar panel is usually calculated:<\/p>\n<p>Theoretical efficiency: The theoretical efficiency of a solar cell is the maximum efficiency calculated based on the principle of photoelectric conversion, which depends on the materials and design used. For example, in theory, the maximum efficiency of a single-junction solar cell is about 33.7%, while the maximum efficiency of a multi-junction solar cell may be higher.<\/p>\n<p>Laboratory testing: Standard test conditions (STC) are often used in laboratories to test the performance of solar panels. Under STC, the light intensity is 1000 watts per square meter and the temperature is 25 degrees Celsius. The efficiency of the solar panel is usually expressed as a percentage.<\/p>\n<p>Formula: Efficiency (%) = (actual electrical energy generated \/ light energy input) \u00d7 100<\/p>\n<p>The actual electrical energy generated is usually calculated by measuring the output current and voltage of the solar panel. The output electrical energy of the solar panel is usually measured in watts (W).<\/p>\n<p>Daily use efficiency: The daily use efficiency of solar panels may be lower than the laboratory test efficiency because it is affected by many factors, such as sun irradiation angle, shadow, dirt, temperature, etc. Daily use efficiency is usually calculated by monitoring the actual power generation and actual solar radiation of the system.<\/p>\n<p>Formula: Daily efficiency (%) = (actual power generation \/ actual solar radiation) \u00d7 100<\/p>\n<p>These methods can be used to calculate the efficiency of a solar panel. It is important to note that the efficiency of a solar panel may decrease over time, so regular performance monitoring and maintenance are key to ensuring the efficiency of the system.<\/p>","protected":false},"excerpt":{"rendered":"<p>How is the efficiency of solar panels calculated?
