Solar street lights are becoming increasingly popular, and many cities are using them for lighting projects. One advantage of solar street lights is that they eliminate concerns about maintenance over time. However, to ensure the long-term functionality of solar street lights, the following data must be considered during their design:
Data required for solar street light design:
1. Determine the latitude and longitude of the installation location by using a solar radiation database specific to different slope angles in the region. This helps establish the tilt angle and azimuth of the solar panels, as well as calculate the standard peak sunlight hours for that area.
3. The number of consecutive cloudy days (d) that the solar street light must endure. This parameter influences the size of the battery capacity needed and the power required from the solar panels to recharge the battery after cloudy days.
4. Determine the number of days (D) between two consecutive cloudy days. This is essential for calculating the power of the solar panel necessary to fully charge the battery after a stretch of cloudy weather.
5. The power (W) of the chosen light source for the solar street light. The power of the light source directly affects the stability of the entire system’s parameters.
This concludes the necessary data for the design of solar street lights. Additionally, due to their unique characteristics, it is crucial to ensure the stability and reliability of the system, making special attention necessary during the design process.
