How to Calculate Solar Street Light System
Solar street lights are a great way to illuminate streets, parking lots, and other public areas without relying on traditional electricity sources. However, designing and calculating the power system for solar street lights can be a bit tricky. Here are some steps you can follow to calculate the solar street light system:
- Calculate the current: The first step is to calculate the current needed for your solar street light system. For example, if you have two 30W lamps in a 12V battery system, the total wattage would be 60 watts.
- Calculate the battery capacity demand: Once you have calculated the current needed for your system, you need to determine the battery capacity demand. This will depend on how many hours of lighting you need per day and how many days of backup power you want in case of cloudy weather or other issues.
- Size the battery: After calculating the battery capacity demand, you can size the battery accordingly. You will need to consider factors such as amp-hour and depth of discharge when selecting a battery.
- Calculate power consumption: It’s also important to calculate the power consumption of your solar light system, which typically accounts for around 5% of total consumption.
- Determine solar panel size: Finally, you’ll need to determine the size of your solar panels based on how much energy they produce and how much energy your system requires.
By following these steps, you can design and calculate an efficient solar street light system that meets your needs.
