Mobile WebSiteWith the popularity of photovoltaic power plants, rooftop photovoltaic power plants are constantly heating up, in addition to our daily household photovoltaic power plants, including industrial and commercial rooftop photovoltaic power plants. The industrial and commercial roof area is large, the roof is flat, the electricity consumption is large, and the electricity consumption is high. Therefore, the installed capacity is large and the power generation is large. From an investment perspective, it is supported by the state and continues to operate for 25 years. Industrial and commercial photovoltaic power generation systems are considered to be a good investment method and generally can be returned within 5-7 years.
Industrial and commercial rooftop PV market analysis data shows. In 2016, the scale of China's industrial and commercial rooftop PV market has exceeded 200GW, and the installed capacity from 2017 to 2020 is expected to reach 33.5GW. From 2017 to 2040, the average installed capacity of rooftop PV systems for industrial and commercial use in China is 5 GW. The benchmark electricity cost of commercial rooftop PV projects in 11 provinces in China is lower than the average daytime commercial electricity price.
New energy trends: small and medium-sized industrial and commercial rooftop photovoltaics have several advantages, and future earnings can be expected
Industry and commerce can achieve parity analysis
1. The cost of photovoltaic power is lower than the price of electricity.
2, the sequential service life of more than 25 years,
3. The electricity consumption of industry and commerce is large and the electricity price is high.
For example, the average daily electricity consumption of a factory is 500 degrees, and the roof area is 10,000 square meters. According to the subsidy before 531, the installed capacity may be installed more because it is profitable. According to 531, it is not necessary to install according to the roof area. You can consider installing it at your own power.
For example, it can be installed around 700KW according to the area. Now, as long as it is equipped with 100KW-150K to maintain its own electricity consumption and maintain most of its own consumption of photovoltaic power generation, it is enough to use 120kw for the average daily consumption of 500kW in three types of areas.
According to the average daily power generation capacity of 500 degrees, 70% of self-use 30% Internet access, daily power of 500 degrees of electricity has 350 degrees of electricity for personal use, industrial and commercial electricity price is calculated at 0.75 yuan / kWh is 262.5 yuan electricity fee, 30% Internet access is 0.37 yuan (local desulfurization no electricity price) The calculation is 55.5 yuan, two total 318 yuan / day income, from the original 500 kWh electricity needs to pay 375 yuan / day, now only need to pay 57 yuan / day.
According to the current market installation price, the cost is recovered within 6 years. After 6 years, the power station is pure income, so the industrial roof is able to achieve parity online. According to the above method, you can understand the ratio of your own electricity consumption.
Of course, not only these, but also some areas of policy support can not be ignored.
Spontaneous self-use projects are policy trends and the general trend of photovoltaic power generation. The installation of photovoltaic power plants with large electricity consumption can save electricity and electricity during the day.
Industrial and commercial rooftop photovoltaic power plant advantages
First, save electricity costs
The benefits of industrial and commercial power stations that can be said at this stage are the savings in electricity bills. China is still in the situation of electricity price upside down. The industrial and commercial electricity price is relatively high. The peak electricity price in the southeast coastal cities can reach more than 1 yuan, and the residential electricity price is lower.
Based on the current situation, the industrial and commercial roof with high electricity price is very suitable for the development of distributed power generation, photovoltaic power generation, with the advantages of no pollution and no noise, installed on the roof, does not occupy additional sites. Moreover, for enterprises, rooftop-mounted photovoltaics can fulfill the government's energy-saving and emission-reduction quotas and even receive additional subsidies. The reason why distributed PV is so hot is based on this.
After the installation cost of the photovoltaic system was reduced, it quickly reached the stage of parity Internet access. At that time, the construction of the photovoltaic power station was started, and there was no risk of subsidy arrears and power cuts. The distributed electricity saved by the photovoltaics had higher yields and no risk.
Second, heat insulation
In the hot summer days, the heat wave is rolling, and in the factory where the machine is roaring, it would be difficult to carry out production without air conditioning. Summer production tasks must be carried out in a harsh environment, and the electricity bills should not be underestimated. If the photovoltaic panel is installed on the roof of the factory, it can effectively reduce the heat insulation. The gap between the photovoltaic panel and the roof can be effectively ventilated to achieve the effect of rapid cooling, and the photovoltaic panel is the thermal insulation layer. According to inspections by professional organizations, photovoltaic panels have been installed to reduce room temperature by 6 degrees in hot summer days. The reduction in room temperature can effectively reduce the cost of air conditioning, and the electricity cost saved is the profit earned by the factory, which is precious for the real economy with low profit margin.
Third, the income can be expected
Nowadays, when the real economy is generally poor, it is not easy to have a good investment. The industrial and commercial rooftop photovoltaics can effectively solve the problem of high electricity prices and high consumption after the opening of “sold wall sales”.
Many people have found it very difficult to do business transformation business before, and the development methods are different in the face of different similar projects.
