As the country’s supportive policies for photovoltaic power generation have been increasingly perfected, there has been a wave of installation booms in rooftop construction sites. People have used the idle resources on the roof for effective use, and on the premise of meeting their own demand for electricity, they have sold surplus electricity to the national grid, saving them. The electricity bill also increased income, and it also implemented energy conservation and environmental protection.
However, please note that not all people, all roofs are suitable for installation of photovoltaic power plants, today we talk about what conditions are suitable for construction, and what situation is inappropriate to build photovoltaic power plants.
These homes are suitable for building photovoltaic power plants
1, users with more electricity
Refrigerators, washing machines, televisions, computers, air conditioners, etc. These basic items cannot be completely lacked in a modern family. When the summer arrives, the electricity bill is certainly not a small number. Therefore, users with particularly high power consumption are suitable for installing photovoltaic power plants.
2, has a clear roof or roof property rights
The construction of a domestic photovoltaic power station requires proof of ownership of the house, and the household photovoltaic power station is built on the roof. Therefore, families who want to build a photovoltaic power station must have independent roofs, or the roof property rights are clear and clear. Therefore, a rural area with a separate roof is more suitable for installation, and citizens in the city often suffer from the lack of a separate roof and cannot be installed.
3, the roof is in good condition
For example, there is no shelter before and after, the roof has enough bearing, the house is relatively new and so on.
4, have a certain degree of economic strength
Why do you say this? Because the initial investment cost of photovoltaic power plants is relatively high, it is not true that there is no certain economic strength!
The saying goes, "First-class investor investment trends, second-rate investor investment opportunities, and third-rate investors can only follow suit." At present, the construction of photovoltaic power plants in rural areas has become a trend. This trend is based on policy support, and the users themselves. condition. With the advent of photovoltaic poverty alleviation in the rural areas, it will bring real benefits to the people and benefit the people.
These situations are not suitable for installation
1, poor lighting conditions in the area
Because photovoltaic power plants can generate electricity only in the presence of light, if your city is year-round fog, rain, or ice and snow, poor lighting conditions, then it is not suitable for the construction of photovoltaic power plants. In fact, most people build photovoltaic power plants are not the real meaning of the above fashion, chasing the trend, they are more concerned about the savings in electricity costs, access to power generation revenue, of course, there are also energy-saving environmental factors.
The year-round haze, rain, or snow and ice, there is no good lighting environment, the income can not be guaranteed, contrary to the original intention of building photovoltaic power plants.
2, poor roof load capacity
Photovoltaic power plants are built on the roof. They must fully consider the fixed load, wind pressure load, snow pressure load and seismic load capacity of the roof. At the same time, they must have sufficient capacity to carry photovoltaic modules, supports and photovoltaic cables.
If these factors are not taken into account, roofs are likely to be crushed under harsh conditions.
3, the roof is blocked
The above problems do not exist, then there are the most basic conditions for the construction of power stations, where we have to remind is to block, obstruction usually refers to something blocking, blocking north and south. There are many factors that cause shelter, which may be between floors, may be vegetation, and may be between components. Do not underestimate the hazards of shielding, the components will be blocked for a long period of time, and the covered solar cell module will generate heat, resulting in hot spot effect. Under severe conditions, the solar cell module will be damaged.
Therefore, before building a power station, it is necessary to investigate the area of ​​the roof and surrounding buildings in advance.
4, roof property is not clear
The user needs to prepare several materials when applying for a rooftop photovoltaic power station: a real estate license or proof of the use of a house; a public roof construction power station requires the construction of a certificate of consent issued by the property and other consent forms of the owner.
In fact, the real estate license is to prove the roof. This house belongs to you. Only in this way can you build a photovoltaic power plant. If you live in a commercial house, then this roof is not your personal! For multi-storey or high-rise residential building roofs belonging to the public area, does not belong to a single household, the entire building residents have the right to use.
If you want to build a personal power station in a public area, you must get the consent of all the landlords. It is not easy for me to do this. If you build a power station by yourself, you are very likely to face the risk of being demolished.
5, did not build the economic strength of the power station
The cost of building a photovoltaic power station is expensive, 5kW photovoltaic power station to 5 million or so, if you are still food and clothing, then please stay away from it! After all, the pre-investment is not a small number, plus the return cycle For 6 years, it is unrealistic to make quick money by investing in photovoltaic power plants.
