Solar Street Lighting System
Solar powered street lights are a very good example on what can be done with solar energy. Solar street lights present the perfect and cost-effective solution for residential streets, parking lots, security, roadways, parking lots and other general area lighting applications.
Solar street lights can be economically viable and efficient in a number of applications, mostly in areas where the cost of providing electricity is expensive or problematic.
A Standard Solar Lighting System includes:
1.Solar Panel
2.Solar Battery
3.Solar Controller Regulator
4.Lighting Sources
5.Fixture
6.Fitting and Mounting
7.Cables etc.
Solar Panel
Its task is to convert the sun's energy into electricity. Different sizes and power outputs are available. Solar panels should be able to withhold and deliver in extreme weather conditions. Some are even designed unbreakable (vandal proof);others will work well in overcast weather. A 20 Year Warranty on good solar panels is not unusual.
Solar Controller
the basic circuitry on most solar powered street lights consists essentially of an automatic battery charger fed by the solar panel and a lighting controller automated for dusk to dawn operation. Automatic lighting can be triggered by a photocell or a timer.
Battery
Maintenance-free batteries are generally used on solar street lights. In addition to providing energy for dusk to dawn operation, they must also be able to supply few days of backup power in case of bad weather or charger failure.
Lamps
the choice of lamps to use in solar powered street lights is dictated by the kind of application you're after:
LEDs (Light Emitting Diodes) also known as SSL (solid-state lighting) have a good color rendition. A cluster of extra or ultra bright LEDs forms the lamp. LEDs consume a fraction of the energy of comparable lighting and have a very long life span. Solar LED street lights are an emerging and promising application for LED technology.
CF (Compact Fluorescent) lamps produce a white light and are used in places where color rendering is desired.
HID (High Intensity Discharge) lamps, mainly LPS and MH:
- LPS (Low Pressure Sodium) lamps generate a monochromatic yellow-orange light and are used when color rendering is not an issue. They have a lifespan of up to 18,000 hours
- MH (Metal Halide) lamps produce a clean white light and are perfect for applications where color rendering is essential
Can also be solar-wind street lights as per request!
