Solar street lights generate electricity by receiving sunlight through solar panels. However, many customers may not understand how to determine the size of these solar panels when purchasing solar street lights. Today, a street lamp manufacturer will explain this issue.
When calculating the size of the solar panel, we must consider the seasonal variations that affect the output of the photovoltaic system, calculating it on a monthly basis. If the load remains constant throughout the year, the calculation for solar panels should be based on the month with the lowest irradiation corresponding to the appropriate angle. If the load varies, it should be calculated monthly to determine the larger capacity of the solar panels.
In determining the capacity of solar panels, it is important to consider other influencing factors, including dust coverage and line losses. First, based on local meteorological and geographical conditions, ascertain the total annual radiation, daily radiation, and peak sunshine hours (considering variations by month). Then calculate the number, power, and daily working hours of the load and determine the system’s direct current voltage based on the load power. After that, compute the capacity of the solar panels based on the peak sunshine hours, and use this capacity to establish the configuration of the solar panels, including series and parallel arrangements, to determine the total power of the solar panel array. Simultaneously, optimize the matching between the photovoltaic components and the battery capacity results.
The capacity of solar panels is influenced by multiple conditions; therefore, the calculations should consider these external and internal factors to better ensure the normal operation of solar street lights.
