Home solar heating products can not mature?
Solar power generation, per square meter of power generation in 120W or so, the cost per square meter in 1500 yuan, the greater the area the lower the price2013 PV industry in Europe and the United States antitrust investigation, overcapacity led to the collapse of a large number of photovoltaic industry in Zhejiang, solar prices have fallen. This can be checked at any time onlineRecommended to buy solar water heater price per price in the 150-180 yuan, including in accordance with the material and other costs, buy a good look at whether there is a reliable after-sales
What are the forms of solar energy? My villa would like to design a comprehensive utilization of solar energy.
Solar heating, refrigeration, as well as solar panels with warm glass, heating room......
What about solar products?Solar panels solar panels
As long as the need to get electricity can. Solar lamp (lamp, landscape lamp, lawn lamp, flashlight, camping lights, lights and so on...), power generation system (Canada now many private power, is the placement of solar panels in the roof)...
Solar energy application technology, there is no prospect
However, from a policy point of view, there is no industry like solar energy so much attention by the country. Compared with the traditional fossil energy, solar energy has obvious advantages. Therefore, the prospects are good.In a word, the future is bright, the road is tortuous!!
Solar energy items in daily life
Solar water heater, charging treasure, rotating wheel, battery board Solar cell / solar engine
Solar panels with single crystal silicon or good thanks
The difference between polycrystalline and single crystal: single crystal plate is black, polycrystalline plate is blue or color.Disadvantages: the same power of the single crystal plate with polycrystalline plate, polycrystalline board area slightly larger than the area of single crystal board, the same as the 50W polycrystalline will be 1.1 times larger than the single crystalThe utility model has the advantages that the polycrystalline plate is a plurality of directions to receive light and has good directivity. The actual test, hypothesis with one hand to block the sun's rays to solar power on the surface of a shadow, so many crystal board power current decrease is not obvious, but the single plate power current is reduced obviously, this is the advantage of multi crystal plate.
PV solar products market sales
The roof of photovoltaic power generation is less than 2 million monthly sales tax, in accordance with the provisions of the national taxation policy, power users need to provide sales invoices to the power supply enterprise, the buyer also need invoice offset the cost, and the personal power does not have the qualification of business owners, led by invoices complicated procedures. More than 20 thousand of the tax can not get the invoice, it increases the difficulty of the sales of power generation households, is not conducive to promotion. The State Administration of Taxation issued, will reduce the tax burden on household electricity."According to the State Administration of taxation documents, since July 1, 2014, the national Power Grid Corp to buy power products distributed photovoltaic power generation project, by the national Power Grid Corp invoices, monthly household electricity generating sales of more than 20 thousand products, owned by the national grid enterprises in accordance with the taxable amount of the 50% generation of vat. The monthly sales of less than 20 thousand yuan may be exempt from vat.
In the domestic high temperature solar energy collector can achieve how many degrees, the existing product and the technology form?
Above three types of high temperature system, although the operating temperature difference is not small, but the overall efficiency is not much difference, both in the 20~25%, and the temperature is high, the comprehensive efficiency is high, the business efficiency is not high.Low temperature solar thermal system, refers to less than 200~300 degrees Celsius, power is almost blank, because the theory of efficiency of solar thermal power generation system at low temperature is relatively low, but personally think that if the utility system developed a reasonable, the comprehensive efficiency and business efficiency is not low.
