The sun villa garden solar lamp pictures big universal street market in the future

Make sure first that the clean energy in the world is as a long-term strategy to develop, so the demand of the solar panels in the future will be very big, have occurred at the beginning of the 21st century China's solar boom for a while, then by the international market, there are



the first thing to determine is that clean energy in the world is as a long-term strategy to develop, so the solar panel ( Solar panels, 太阳能板) Is by absorbing sunlight, the solar radiation through the photoelectric effect or photochemical effect directly or indirectly converted into electrical energy device, the main material of most of the solar panel as the 'silicon', but because of the production cost is larger, so it widely used, we still have some limitations. 】 In the future will demand is very big, have occurred at the beginning of the 21st century China's solar boom for a while, then by the international market, now a little disappeared. But in the second half of last year, the state shall encourage local policies to develop solar power, so you can see China as a market just rebirth.

but due to the life of solar panels is very long, so now not sure now can the unsold inventory is depleted. And as local lighting is different, so the utilization rate of the panels are also different. So the penetration will be restricted.

for now, '' solar street lamps, this year has also been done, but because of low solar energy conversion efficiency ( Polysilicon by about 15%, monocrystalline silicon by about 25%) / affected by the weather, geographical limitations lead to electricity far cannot meet the demand of 'street', at the same time also limits the expensive cost in street lamps may add more panels ( Maintenance costs will be high)

what virtue LED bulbs? When fully charged can lighting, lack of time can not meet the lighting requirements completely, and the range of light is very small, when it may be nice desk lamp, street lamp is not enough. So in front of the technical innovation, solar street light the individual does not look good.

the reasonable direction of solar power is 【 The sun is a huge endless clean energy center, in the inside the sun by the 'h' to 'helium' nuclear fusion has been going on for the billions of years, its energy into space radiation power of 380 thousand quintillion kw, one in 2. 2 billion m to the earth's atmosphere, 30% is the atmosphere reflection, 23% is absorbed by the atmosphere, the rest of the reaching the earth's surface, its power is 80 trillion kw, that is to say, the sun shone every second to the earth's energy is equivalent to 5 million tons of coal combustion heat release. 】 And distributed power supply, the former barriers to nine digits, the latter can play almost eight digits, perfect cases, 5 - Back 10 years investment, panels depreciation fixed number of year is usually 25 years.

first thought of these, later added.

solar street light prospect is very good, long roads, supply exceeds demand, market saturation, hope the cost is cheaper and cheaper, more and more long life

according to Taiwan's optical industry technology development association expects global LED street lamp 【 LED street lamp is made of street lamp, LED lamps and lanterns with high efficiency, safety, energy saving, environmental protection, long service life, fast response speed, high color rendering index of unique advantages, the city lighting energy saving is of great significance. 】
