A battery based solar street light is a stand alone system, which will store electricity generated by solar panel in solar battery. Solar LED street light is powered by photo-voltaic panel, generally mounted on the light structure or integrated in the pole itself.
There is also another type of street light called integrated solar street light. In both type of street lights, the photo-voltaic panel charge solar battery during day time, which powers LED lamp during night. Street light comes with dusk to dawn sensors, which automatically switch-on the light in evening and off in the morning.
12w Solar Street Light
For 12 watt street solar LED light, the technical specifications are as below. You can check and compare it with other models of solar lights.
15w Solar Street Light
This is the most common size of solar light. If you want to install a solar light at your places, then 15 watt solar light is best for you.
18w Solar Street Light
18 watt solar PV light is best solar solution to illuminate your gardens, grounds, parks etc
24w Solar Street Light
A 24 watt solar street LED light is useful for national highways, roads, factories and such places where more light is required.
Benefits Of Solar Lights
Environment Friendly : Contain no mercury and longer component fixtures life, means less waste. A guarantee of 80% lumens and maintenance even at the end of 50,000 hours of operation. This solar LED street light range offers a number of environmental advantages over other types of lighting.
Lower greenhouse gas emission: The DOE estimates rapid adoption of LED over the next 20 years can eliminate 258 million metric tons of carbon emissions.
Reduce – Reuse – Recycle: Solar LED products are made using a total of 20-25% (by weight) post consumer recycled materials. Seventy percent (by weight) of LED components are aluminum castings and extrusions that are readily recyclable. Corrugated packaging is 100% recyclable.
Solar Lights use less energy: Because street light applications are generally use 40-60% less energy compared to traditional high-intensity discharge (HID) products. So, these products are energy efficient.
Optic Product Technology: Optic is a direct-refractor that minimizes light losses and provides superior target performance. Light from LED is directed where it’s intended, without any waste.
Efficient thermal management : Proper thermal management is key to longevity. Each light bar is mounted to heat sinks to assure LED’s are operating at the ideal temperature.
