There is a saying in 2018 that is very hot, called: poverty limits my imagination! Indeed, in this era when money is everything, you never know how local tyrants live (of course, local tyrants do not know how we live). The myth of wealth that is rich overnight is not common. The way for most people to achieve wealth freedom is nothing more than the accumulation and rational use of their own resources. For example, we are going to install photovoltaic power plants on the roof of industrial and commercial buildings today.

Unlike Internet companies, which only need one office to make a home, manufacturing companies often need a lot of capital investment, including the construction of the factory. How many bosses who want to rely on product manufacturing to achieve wealth freedom, in the early days, rely on loans forcibly operating? The bosses are operating and managing the company every day. The most important thing is how to "open source and reduce expenditures". If you happen to have a good industrial and commercial roof, congratulations, installing a photovoltaic power station on the roof will immediately give you more wealth than other bosses.
After the 531 New Deal, industrial and commercial photovoltaics are the most popular
Since the implementation of the 531 New Deal, the photovoltaic emergency weaning, the industry has also entered a cold winter period, originally had a desired household photovoltaic, after a number of insignificant articles were issued, so that PV people can not see hope, but they are limited The development of centralized power plants is even less necessary to watch, so some single-business PV companies can only choose to leave the market. There are many opinions about the 531 New Deal, and we will not discuss it anymore.
After weaning and shuffling, what we can see is that the advantages that can be seen after waiting for the price to go online are well reflected in the distributed industrial and commercial photovoltaic projects. On the one hand, the system cost has dropped drastically, which has greatly reduced the investment cost of industrial and commercial photovoltaic power plants; on the other hand, the cost of electricity for industrial and commercial use itself determines the value of photovoltaic power generation. The combination of these two advantages has allowed the industrial and commercial PV parity era to come ahead of schedule. For some enterprises with strong self-sufficiency, they have basically achieved PV parity online.

Therefore, many enterprises have accelerated the plan to build rooftop photovoltaics. For some enterprises with difficult capital turnover, there are powerful photovoltaic companies to invest and build. Enterprises with high-quality roofs can enjoy low-cost photovoltaic power at zero cost. Whether it is the company's own investment in construction or the free investment of investors, industrial and commercial photovoltaics has become the most popular investment project at the moment, and the boss with high-quality roof should laugh.
How is this wealth calculated?
So what are the benefits of building a photovoltaic power plant on the roof of your own factory?
1. Revitalize fixed assets and increase profits
Some production enterprises have hundreds of tens of thousands of flats on the roof, and these large-scale idle sites have become valuable resources after installing PV on the industrial and commercial roofs, which has revitalized the company's fixed assets and increased the company's income.
2. Save electricity costs, surplus electricity online sales
Enterprises use large amounts of electricity and have high peak electricity bills. After installing photovoltaic power generation, enterprises can use their own electricity and use surplus electricity to access the Internet. Take Shanghai as an example. The peak price of the two-factory commercial and commercial peaks under 1 kV is 1.127 yuan/kWh, which saves a lot of electricity bills when used by itself. At the same time, the surplus electricity can be sold to the national grid on the grid. The income can be described as quite objective. Photovoltaic power generation not only solves the problem of electricity consumption of the enterprise itself, but also generates additional economic benefits for the enterprise.

3. Promote energy saving and emission reduction
Industrial and commercial photovoltaic power generation systems can reduce energy consumption of enterprises and complete government-defined energy conservation and emission reduction targets. In addition to being free from the geographical distribution of resources, the advantages of using building roofs are safe, reliable, noise-free and pollution-free.
4. Improve the environmental comfort of the plant
The photovoltaic panel has the function of heat insulation. After the photovoltaic module is laid on a large area on the roof, it can effectively reduce the temperature of the plant by about 6 °C, creating a more comfortable working environment in the hot summer, and indirectly saving the air-conditioning cost of the enterprise.
Precautions for the development of industrial and commercial photovoltaic projects
Enterprise strength and industry
The life of photovoltaic power plants is more than 20 years. In the development of distributed power plants, the owner's survival should be tested. It is better to choose the cooperation of the owners with strong enterprise strength, good industry prospects, business management norms and financial formalities.
The operating industry of the owner's enterprise also has an impact on the construction of distributed photovoltaic power plants. If the enterprise produces inflammable and explosive dangerous goods, emits corrosive gases, and discharges a large amount of smoke, it is not suitable for the construction of distributed photovoltaic power plants. In addition, it is necessary to consider the power consumption capacity of the enterprise itself to build a power station of a suitable size.

Pre-exploration
Pre-exploration can be said to be the most critical part of industrial and commercial PV project development. It involves many aspects of power plant design and maintenance in the later stage. The premise of high-quality power station is good on-site exploration.
The first is to determine the type of roof, flat roof or color steel tile roof, and take into account the roof's ability to withstand, and secondly, must consider the occlusion situation, some of the severely occluded roof is not suitable for the construction of the power station, because the power generation is very Large, economic effects are poor. According to Mr. Wang Shujuan's point of view, high power generation is the most effective way to reduce the cost of system electricity, so shadow occlusion can not be ignored, including existing shadows and possible future shadows need to be considered.
Equipment selection
Photovoltaic cell modules, inverters and other equipment must be certified by a certification body approved by the National Certification and Accreditation Administration. Meet the technical requirements of the relevant access grid. It is necessary to take into account the cost of grid connection and also consider the quality of the power station.

Later operation and maintenance
After visiting several rooftop power stations, we found that many of the owners reported that the low power generation was caused by the lack of maintenance. Photovoltaic modules need to generate more electricity under light and light transmittance. If the power station cannot be cleaned and maintained in time, the power generation will decrease. Relevant data also shows that the often cleaned PV power plants generate 3 to 6% more electricity than the clean photovoltaic power plants, so the later operation and maintenance can not be ignored.
