What is the advantage of industrial and commercial rooftop pv power plant?

With the popularity of photovoltaic power station, rooftop photovoltaic power station in constant temperature, in addition to our daily household photovoltaic power station, including industrial and commercial rooftop photovoltaic power station. Industrial and commercial roof area is large, flat roof, power consumption, electricity price is high, so the

with the popularity of photovoltaic power station, the roof is heating up photovoltaic power station, in addition to what we call the household photovoltaic power station, including industrial and commercial rooftop photovoltaic power station. Industrial and commercial roof area is large, flat roofs, and large power consumption, electricity price is high, so the capacity is big, capacity is big. From the investment point of view, because the state supports and continue to operate for 25 years. Industrial and commercial pv power generation system is considered to be a better investment mode, can be in 5 - Seven years to restore to its original capital. First of all, save electricity, so to speak, at this stage the benefits of industrial and commercial power stations is to save electricity. China is still in the electricity price upside down. Industrial and commercial electricity price is relatively high. Southeast coastal city of the highest electricity price can reach more than $1, and residential electricity prices are relatively low. From the point of current situation, higher electricity prices of industrial and commercial roof is very suitable for development of the distributed power generation and photovoltaic power generation. They have the advantages of no pollution and no noise, installed on the roof, do not take up extra space. For enterprises, photovoltaic roof can complete the government issued the task, energy saving and emission reduction can even get extra subsidies. This is the reason why distributed photovoltaic so hot. After the installation of a photovoltaic system cost reduction, will soon achieve affordable Internet stage. At the appointed time, the construction of photovoltaic power station will be no profits subsidies under the risk of default and give up photoelectric ration. Save electricity distributed photovoltaic systems have higher returns, and no risk. Second, heat insulation energy-saving in the hot summer, heat wave, in the roaring machine factory, if there is no empty adjustment, is hard to production. Summer production tasks must be carried out in the harsh environment and power costs should not be underestimated. If photovoltaic panels installed on the roof of the factory, and can effectively decrease the heat insulation effect. Photovoltaic panels and the gaps between the roof can effective ventilation, to achieve the effect of rapid cooling. Photovoltaic panels is heat insulation layer. According to the testing of the specialized institutions, installation of photovoltaic panels can reduce 6 degrees at room temperature in the hot summer. Low room temperature can be regulated by 0 + effectively reduce costs. Saving electricity is all factories to earn profits, it is very valuable for low profit of the real economy. Third, the general income period in the real economy, to make good investment will not be easy. After the 'sell electricity partition wall' is about to open, the industrial and commercial rooftop photovoltaics can effectively solve the problem of large electricity price is high, the power consumption. Many people find very difficult doing business in change for family use. Face different kinds of similar projects, development methods are also different.
