Solar LED street lamp market is huge
We know that global lighting electricity accounts for 20% of the total electricity, and a large part of which is used in outdoor lighting. China is no exception. According to statistics, China has about 200 million of the lamps in the installation. Street lights on average is about 200 watts, assume that every day
we know that global lighting electricity accounts for 20% of the total electricity, and a large part of which is used in outdoor lighting. China is no exception. According to statistics, China has about 200 million of the lamps in the installation. Street lights on average is about 200 watts, assume that open for ten hours a day, so every day is 2 degrees, 365 days is 730 KWH, 200 million is 146 billion KWH. And China's largest hydropower station of the Yangtze river three gorges hydropower station 26 units fully put into production after the annual capacity to 84. 7 billion KWH. So all street lamp power consumption is about two of the three gorges power station by electricity. This is by no means a small number. What's more, now also in 20 million a year of the lamps in the speed increase. Just now almost 90% are using high pressure sodium lamp. Although it is still very high luminous efficiency, but its short service life, power consumption, low color temperature, color rendering is poor, but also contain mercury and other toxic substances, the future will be eliminated sooner or later. Since the Ministry of Science and Technology puts forward to develop the LED street lamp 'ten city wan light' plan later. Now the LED lamp is with high speed development in full speed. Unfortunately, more than 90% of 'ten city wan light' or adopt ac LED street lamps, or transform existing high-voltage sodium lamp for LED street light. According to conservative estimates, the total number of ten city wan light plans will be more than 2 million, but it is only an annual increase of street lamp one over ten of the total. As said earlier, if every new 20 million lamp that USES the solar energy, then the total output will reach 4 million kilowatts, actually is much more than this number, because usually solar LED street lamp used in solar panels power is 3 - actual street lamp power 4 times. Is assumed to be 3 times, LED street light, so the total installed capacity of solar panels will reach 12 million kilowatts. China in 2008, the total output of solar panels to 1. 78 million kw ( 1780 megawatts) 。 Is far from to supply the demands of solar street light. Thus the market of solar LED street light, is by no means a dispensable market, it is a very important market.
