How to Calculate Solar Street Light System Requirements - Queneng
1. Determining the Load
This is the first and most crucial step. You need to determine the total wattage required by your street lights. This involves:
* Number of lights: Count the number of streetlights needed for the area.
* Wattage per light: Check the specification plate of your chosen LED street light to determine its wattage consumption.
* Total wattage: Multiply the number of lights by the wattage per light. Example: 10 lights x 50W/light = 500W.
2. Calculating Energy Consumption
Next, determine the daily energy consumption:
* Operating hours: Determine the number of hours the lights will operate daily. This often depends on the location and local regulations (e.g., sunset to sunrise).
* Daily energy consumption (Wh): Multiply the total wattage by the operating hours. Example: 500W x 8 hours = 4000 Wh (4 kWh).
3. Sizing the Battery Bank
The battery bank must store enough energy to power the lights during periods of low or no sunlight. Consider:
* Battery capacity (Ah): This is crucial and depends on several factors including the daily energy consumption and the desired autonomy (number of days the system can operate without sunlight). Choose a battery system with sufficient capacity. Remember to account for battery efficiency (typically 80-90%).
* Battery voltage: Select the appropriate voltage (e.g., 12V, 24V, 48V) based on your chosen lights and charge controller.
4. Selecting Solar Panels
The solar panel array needs to generate enough energy to meet daily consumption and recharge the batteries.
* Panel wattage: Consider panel size, efficiency, and available sunlight. Consult solar panel datasheets for power output under specific conditions (STC).
* Number of panels: Divide the daily energy consumption by the individual panel wattage (considering sunlight hours and system losses) to determine the required number of panels.
5. Choosing a Charge Controller
The charge controller regulates the flow of electricity from the solar panels to the battery bank, preventing overcharging and damage.
* Controller amperage: Select a controller with an amperage rating that exceeds the maximum current output of the solar panels.
* Controller voltage: This should match the battery bank voltage.
6. Considering System Losses
Always factor in system losses (wiring, battery efficiency, temperature effects). A 10-20% loss is a reasonable estimate.
