Solar DP Street Light
Shree Solar Ventures manufactures Integrated Solar Street light in 15W, 20W, 30W, 50W, 80W and 120W LED power. Integrated Solar Street light consists of a Solar panel and LED luminary with built-in Lithium-ion / Lithium Ferro Phosphate battery (LiFePO4) battery and solar driver card with charge controller. In addition, LED luminary has a motion sensor to increase / decrease the LED light brightness on detecting any movement near the solar light.
As we can mount the solar panel independently in true South facing direction, Integrated Solar Street lights provide better performance as compared to All In one Solar street lights. Also, Integrated Solar Street light provides better value to customers in terms of cost as compared to traditional solar street lights. Since the battery is inside the LED light housing in integrated Solar Street lights, this eliminates the need for external battery box, which is part of traditional solar street lights. Moreover, eliminating the external battery box reduces chances of battery theft / vandalism. Hence, integrated solar street lights provide better value to customers without compromising on performance.
The solar light with battery can also be used to retrofit exiting solar lights where either the solar luminary is not working or the battery has been stolen / exhausted. The customer can still utilize the solar panel from earlier setup. The solar light with battery can be installed on exiting light shoulder on the pole and simply connected to the solar panel to resume operation. This retrofit solution helps utilize the remaining value from earlier installation (thereby enhancing the environmental benefits) and also helps in reducing costs.
Working of a Solar Street Light
On receiving sunlight, the solar panel in solar street light produces electric power (blinking green color LED indicates the battery charging process during daytime). This power charges the battery during daytime. After sunset, the solar street light starts glowing automatically. The LED light consumes power stored inside the battery during daytime. A motion sensor uses Infrared motion sensor to detect any movement around the light (working explained later). This helps in conserving energy and providing better backup especially in cloudy or foggy weather conditions. Systellar also provides the option in solar light with battery to switch On/Off the motion sensor functionality. This special functionality can be requested at the time of placing order for Integrated solar street light or the solar light with battery.
