The function of the solar panel is to convert the sun's light energy into electricity, and then store the direct current in the battery. Solar panel is one of the most important components in solar power generation system. Its conversion rate and service life are important factors to determine whether solar cell has use value.
Solar cell components can form a solar cell array of different sizes, also known as solar cell array. The power output capacity of solar panels is closely related to its area size. The larger the area is, the larger the output power will be under the same lighting conditions. The advantages and disadvantages of solar panels are mainly measured by the two indexes of open circuit voltage and short circuit current.
