Solar Street Light Charging and Discharging

What is a charge controller in a solar street light?

Charge Controller Charge Controllers regulate the charging and discharging of the battery They regulate the incoming voltage to charge the battery and prevents the deep discharge of the battery. In a solar street light, the circuit to switch on and off the luminary is enclosed along with the charge controller.

What are the key parameters of solar street lighting systems?

Email: [email protected] | WhatsApp: +8615068758483 We aim to introduce the key parameters of the solar street lighting systems, including the power of the street light, the wattage of the solar panel, the capacity of battery, the solar charge and discharge controller and the street light controller.

How does a solar street light controller work?

When the charging process stops at dusk, the controller prevents the backflow of electricity from the battery through the solar cells. PWM and MPPT are commonly used controllers in an outdoor solar street light unit. The light pole provides support to mount the solar panels and LEDs with other components of solar street lights.

How solar LED street light works?

The working principle of solar LED street light is to convert solar energy into electric energy so as to realize lighting. Photovoltaic modules made of polycrystalline silicon absorb solar energy and convert it into electric energy during the day, and then store the electric energy in the battery under the control of photovoltaic controller.

How much solar power does a street light use?

For a street light that consumes 900WH, after calculation, the battery panel power required by the former =900*1.333/6.2=193.5 Wp, and the battery panel power required by the latter=900*1.333/4.6=260.8 Wp. From this we can conclude that the more sunlight there is, the smaller the solar panels you need and vice versa.

How to design a solar street light system?

The first step in designing a solar street light system is to find out the wattage and energy consumption of the LED street lights, as well as the energy consumption of other parts that require solar power, such as WiFi, cameras, etc. How to calculate the total energy consumption of your solar system?
