1. Procedure for calculating the amperage of a 100watt solar panel
The first thing you need to understand is that a volt (V) is a unit of voltage used to express the magnitude of electric potential between two points in a circuit. Voltage plays an important role in converting between watts to amps acting as an intermediate value, in other words, what you need to know is that in order to know how many amps a 100watt solar panel is equal to, you have to know what voltage a 100watt solar panel operates at first.
The best way to get your 100watt solar panel is to check your solar panel’s instruction manual, the manufacturer will state the voltage rating of the solar panel, which is the maximum safe voltage that your 100watt solar panel can operate at, on the solar panel’s instruction manual for your reference.
If your solar panel instruction manual is lost, you can ask a professional to measure the voltage of your 100watt solar panel for you, which involves professional electrical knowledge, you should try not to measure it by your own hands, in order to avoid any safety accidents. Normally, 100watt solar panels are rated between 12V and 24V.
After getting the middle value of watts and amps in volts, you can use the 100watt solar panel to amps formula to realize the conversion of watts to amps, you need to substitute the data you get into this formula below:
Solar panel amps = Solar panel watts / Solar panel rated voltage.
For example, suppose your 100watt solar panel is rated at 12V, then you can calculate the amperage of the solar panel by using the formula, and substitute the data to get the amperage of your 100watt solar panel is 8.3A.
2. Factors affecting the calculation of amperage of 100watt solar panel
Many factors can cause the amperage of your 100watt solar panel to decrease, such as the cleanliness of the surface of the solar panel, the light intensity of the external environment, the tilt angle of the solar panel, and the temperature of the solar panel, etc. All of these factors ultimately lead to a decrease in the efficiency of the solar panel’s power generation, which in turn affects the amperage of your 100watt solar panel.
Take the cleanliness of the solar panel as an example, the surface of the solar panel is too low in cleanliness (accumulation of dust on the surface of the solar panel), and this dust will block the solar panel’s absorption of sunlight, which in turn leads to a decrease in the power generation efficiency of the solar panel, making the total wattage of the solar panel lower. In this way. With a lower solar panel wattage, the solar panel can only work at a lower wattage, and accordingly the amperage and volts of the solar panel will be lower.
So, in order to make your 100watt solar panel work efficiently, you should pay attention to the post maintenance of your solar panel, including cleaning the dust regularly, paying attention to the tilt angle of your solar panel and avoiding the temperature of your solar panel to be too high.
3. Summary
Through the in-depth understanding of the principle of calculating the amperage of 100watt solar panels, you can calculate the current size of your solar panels, which is helpful for you to have a better grasp of the working condition of your solar panels, of course, good post maintenance work can not only keep your solar panels working efficiently, but also extend your equipment’s service life.
