Solar energy is clean and renewable. Mostly importantly, it is free of charge. Therefore, solar LED lights are ideal for outdoor illumination. Our ST43 solar LED street lights were installed in the courtyard in Italy. This courtyard also served as a parking lot. With high quality and large capacity LiFePO4 battery, ST43 could provide sufficient lighting up to 7 rainy days with only 8 hours of charging. This powerful lighting ensured the safety for both drivers and pedestrians. Thanks to the all-in-one design, ST43 was easy to install with the integrated solar panel, battery, controller, and sensor. Moreover, no wiring and no electric grid were needed to bright the courtyard. The use of solar lights also reduced the carbon footprint and protected the beautiful scenery around the courtyard.
