🔋 Batteries: The Heart of the System
The battery is the beating heart of a solar street light with a camera, storing sunlight’s energy to power both the LED and the camera 24/7. Most systems use Lithium Iron Phosphate (LiFePO4) batteries for their safety, longevity, and high energy density.
How It Works
Solar panels convert sunlight into electricity via the photovoltaic effect, where photons dislodge electrons in a semiconductor, creating a current. This charges the battery during the day, storing energy as chemical potential. At night, the battery powers the LED and camera, with a controller ensuring efficient energy use.
Battery Specs
- Capacity: 345.6-618.4Wh (e.g., 12.8V, 30-60Ah) for all-in-one systems.
- Cycle Life: 2000-4500 cycles at 80% Depth of Discharge (DoD), lasting 5-10 years.
- Voltage: Typically 12.8V (4 LiFePO4 cells at 3.2V each).
- Weight: 5-15kg, lighter than lead-acid’s 15-40kg.
LiFePO4 batteries offer three times the storage of lead-acid and thrive in extreme temperatures (-20°C to 60°C), making them ideal for diverse climates.
Sizing the Battery
To ensure the system runs smoothly, you need to calculate battery capacity:
[ \text{Capacity (Ah)} = \frac{(\text{LED Power (W)} \times \text{Lighting Hours}) + (\text{Camera Power (W)} \times 24 , \text{h})}{\text{Battery Voltage (V)}} \times \text{Autonomy Days} ]
Example:
- LED: 30W, 12 hours/night.
- Camera: 5W, 24 hours/day.
- Voltage: 12.8V.
- Autonomy: 3 days.
[ \text{Total Energy} = (30 , \text{W} \times 12 , \text{h}) + (5 , \text{W} \times 24 , \text{h}) = 360 , \text{Wh} + 120 , \text{Wh} = 480 , \text{Wh/day} ]
[ \text{Capacity} = \frac{480 , \text{Wh} \times 3}{12.8 , \text{V}} \approx 112.5 , \text{Ah} ]
[ \text{Adjusted for 80% DoD} = \frac{112.5}{0.8} \approx 140.6 , \text{Ah} ]
A 150Ah LiFePO4 battery ensures reliability, even during cloudy days.
