Even if the encounter rainy weather, the latest development of solar street lighting over five days can be. Yesterday, Shunde private Schwab Lighting Academy was established to invest 20 million yuan to join solar lighting technology joint research and development center, the two sides will research key photovoltaic power generation technology that allows solar lights intelligent regulation. It is learned that different from ordinary solar street lights, lighting Schwab CAS jointly developed "intelligent control circuit" system through the switching device, according to the sky brightness and personal needs 24 hours a day inside the automatic adjustment of brightness in a variety of environments. At the same time, the system can allocate the proportion of solar power for lighting and storage, and then graded according to the brightness of the lights discharge to ensure full battery power lights sunny days, but also for use in rainy day, do not result in waste thus more energy efficient. Institute of the person in charge, currently 80 per cent of the maximum utilization of solar cells, namely through MPPT "Maximum power point tracking" technology optimized utilization rate up to 95%. Such as solar lamp charging day, can generally be lit 6,7 hours, and after the introduction of new technology, solar lamp lighting time can reach 15 hours or even longer. According to this principle, the current development of Chinese Academy of Sciences Schwab lighting and solar lights, lights in rainy weather generally use 3-5 days.
