Note: 1. The output power of solar panels depends on solar irradiance, solar panel temperature, and other factors. Therefore, the measurement of solar panels needs to be done under standard conditions (STC). The standard conditions are defined as: air quality AM1.5, light intensity 1000W/m2, and temperature 25°C. 2. Under these conditions, the maximum output power by the solar panel is called the peak power, which is usually measured by a solar simulator. The main factors affecting the output performance of the solar panel are load impedance, sunshine intensity, temperature, and shadow.

Attention: There may be some small spots on the side of the solar panels, but this is a normal phenomenon and will not affect the function of the solar panels. Please choose the cells carefully, as they are micro and super thin. The color may vary from deep blue to pale blue due to the production process, but the function remains the same.

On the use and testing: The product can only be used in direct sunlight. The nominal power is measured at noon sun peak. In the morning, evening, or under not-so-strong sunlight, the output may not reach the nominal value. Therefore, the buyer should be aware of this. Inside a room, the solar panel is almost impossible to detect any meaningful value, as the ordinary light and the sun light are very different. Be sure to test the solar panel under direct, strong sunlight.
