Solar energy is all sorts of renewable energy in the most important basicenergy, biomass, wind energy, and power, water comes from the solar energy and,by extension, the solar energy include the above all kinds of renewable energy.Solar energy as a kind of renewable energy, it is to show the direct transformation and the use of solar energy.

At present, the world"s mostmainstream solar power mode is a photovoltaic mode, use the light ofsemiconductor interface born v effect and the light directly into electricity ofa kind of technology, the key element is solar cells. Solar cells after seriesencapsulate protection after can form large area of solar cell module, togetherwith the controller, etc. Parts of the power it formed a photovoltaic powergeneration device.

Photovoltaic power generation equipment

(pv)power realized to the wishes of the human solar energy utilization, at present,our country, the United States, Japan and Europe are developing (pv) powerindustry, energy agency estimates that by 2030, is expected to account for theentire photovoltaic capacity of the will of the capacity by 10%. Photovoltaicpower generation and the traditional thermal power generation with a lowpollution, without the consumption of resources advantage, but why has beendeveloping still slowly? This and our country (pv) power of the currentsituation and characteristics of (pv) power itself about:

One of the high cost, and photovoltaic power generation, limiting (pv) power of commercialoperation. At present, the solar photovoltaic power generation investmentconstruction cost about $32000 per kilowatt, and conventional thermal powerinvestment cost per kilowatt of about 3000 to 4000 yuan, pv electricity pricesare conventional thermal power 3 times of the electricity price, the cost too ishigh is the major obstacles photovoltaic scale of development.

Second,(pv) power energy storage is the technical bottleneck, cannot achieve 24 hoursof power supply, its application field to sell at a discountgreatly.

Third, our pv product the main raw materials--silicon 95% relyon imports, the products are heavily dependent on exports, lack of the abilityof independent innovation, a foreign factory

Four, and photovoltaictechnology to the lag of the environmental problems and high energy consumptionproblem highlights. Photovoltaic products still exist environmental problems,also can"t reach all the domestic material circulation, and clean production,large scale application but more pollution environment.

Yally Electronic Co., Ltd is a commitment to new energy products development of high-tech enterprise, engaged in the solar powersystem solar lights product r&d and sales, new rural construction to obtain the effective promotion andapplication, and exports to Asia, Europe, America, Africa"s countries and regions.
