Description
Solar street lighting systems use photovoltaic cells or batteries to convert sunlight into electricity. If you come across a solar lighting system, note the dark panel on top of the light. That is the panel of the photovoltaic cells, which will convert sunlight into electricity. This electricity will then be stored in the batteries. This power can be used as and when needed. The batteries being connected to solar cells, charge themselves continuously while the solar panel is being exposed to available Sunlight. These batteries are inbuilt into these lighting systems. Hence the lamps are capable of drawing light from them. This consequently negates the solar lighting systems from any kind of need to be attached to wires, for power transmission.
Solar street lighting system is ideal for street lighting in remote villages. The system is provided with battery storage backup sufficient to operate the light for 10-11 hours daily. The system is provided with an automatic ON/OFF time switch for dusk to dawn operation and overcharge / deep discharge prevention cut-off with LED indicators. The SPV modules are reported to have a service life of 15-20 years. Tubular Batteries provided with the solar street lighting system require lower maintenance; have longer life and give better performance.
Advantages of Solar Street Lighting system
- Easy to install and Simple to operate.
- Energy-saving, pollution-reducing, money saving.
- A key feature of contemporary solar street luminaires is the battery management system, which facilitates motion and night sensors.
- No cable-laying work or complicated power facilities needed.
- These are water-resistance and weatherproof.
- They have a low glare and low insect attrition rate.
- This light uses solar panels to convert solar energy into electrical energy which is stored in the inbuilt battery for dusk-to-dawn lighting.
- In the first five hours of the night, the performance of the system is up to medium-level brightness.
- The intensity of light decreases progressively until dawn or till the time the PIR sensor is activated by the movement of humans.
- In comparison to conventional street lights, solar outdoor luminaires require almost no maintenance.
