Urban Green Energy Inc has installed 120 solar and wind-powered streetlights in PingQuan, situated in the Hebei province of China. Instead of opting for costly traditional lights that would have needed to sink wires into the ground and connect to the grid, the city chose a more sustainable route. Each Sanya light is equipped with a HoYi! wind turbine and two 280 watt solar panels, allowing them to function completely off-grid.
During August and September of 2012, New York-based UGE helped to usher in a new era of urban design in PingQuan, China. They set up 120 efficient LED street lights where there was previously no illumination. It would have cost the city a hefty sum to dig up the road and set the wires so the off-grid streetlights were a worthwhile investment. Wind turbines and solar panels create power that is stored in a battery at the base of the light. The battery is capable of storing up to 3-5 days of backup energy. With a slim profile and modern look, the lights were also meant to make an aesthetic statement. Appearing modern without being overbearing, they show the region’s commitment to green technology.
UGE’s hybrid system has the advantage of being able to harness energy from both the wind and the sun. (When one energy source is high, the other tends to be low.) Seasonal changes exacerbate this effect, so by adding both methods of energy collection, the lights are able to harness the energy year-round and day or night.
Again, another example of a misapplied alternate energy demonstration project. The system should have been demonstrated in an area similar to the target sales market. The only application of these street lights are on urban streets with pedestrian traffic or at highway intersections in rural areas not on a straight stretch of rural highway without tall trees or sun and wind obstructing structures. Why would we want to add to more light pollution and they are dangerous due to their effect on night vision anyway. It is obvious the cost benefit don\'t work! From the pictures you can see that there exists grid ties all along the highway(the bill boards and the buildings) so the feeder cost is small and the electric cable to link each street light is much much less than all the cost of the PV and VAWT. The maintenance cost of cables is nearly NIL while maintenance of the electronics, PV, battery and windmill is exorbitant. Even when you add up the grid distribution losses and electrical generation fuel costs there is no payback especially considering that China imports 17.5% of its coal nearly half of which comes from the USA. So the USA in shutting down coal power plants and increased the coal available for export to China where China burns it in not environmentally kind electric generating power plants to make their PV that they install on a stretch of road making it more dangerous to replace a hundred yards of aluminum electric cable per light standard and to top that all off China is the largest producer of aluminum on the planet. The world has gone crazy! But the world is less crazy than the USA the target market for these off-grid street lights. The city of PingQuan, China had a goal to make an aesthetic statement and to show the region’s commitment to green technology. I can only Hope that cities in the USA don\'t Change and further pollute other regions in China not shown in the video from the coal and chemical carcinogens needed to manufacture the stupid PV.
