Upgraded components boost efficiency of solar streetlights

 

PV panels with higher conversion rates are used in the latest designs. LED bulbs and intelligent controls enhance performance.

 

TOP TRENDS

  • More efficient PV panels: China suppliers are adopting solar modules with conversion rates of at least 17 percent, enabling these to gather and produce energy even in inclement weather. To ensure efficient operation, PV cells are encased in an anodized aluminum frame with toughened low-iron tempered glass, while junction boxes are sealed for water resistance.
  • LED light source: LEDs are the main source of illumination since these are more energy-efficient than incandescent bulbs and CFLs. The latest streetlights adopt diode-fitted lighting modules with a life span exceeding 50,000hr.
  • Light sensors: Many manufacturers are combining light sensors and time controls for greater efficiency and user convenience. Models with both systems are priced 10 to 15 percent higher than units employing only time controls.
  • Hybrid designs: Several releases are fitted with vertical wind turbines to ensure continued operation regardless of the weather.
