Construction Guidelines and Precautions for Household PV Power Plants

With the development of the photovoltaic industry in recent years, many domestic traditional companies have begun to pay attention to new energy fields. However, most companies entered the photovoltaic industry and discovered that it is not an opportunity for gold everywhere. Since 2009, a large number of old photovoltaic equipment manufacturers have basically disappeared or transferred to foreign markets, but they still cannot resist more and more traditional manufacturing enterprises. To squeeze in this "looks good" circle.

At present, distributed photovoltaics are very popular. We believe that this large development trend is obvious to everyone and can be seen.

Distributed photovoltaics have great advantages. Do you all know?

First, the output power is relatively small. In general, a distributed photovoltaic power project has a capacity of several kilowatts or less. Unlike a centralized power station, the size of a photovoltaic power plant has little effect on power generation efficiency, and therefore its economic impact is also small. The investment yield of a small photovoltaic system is not lower than that of a large-scale one.

The second is small pollution and outstanding environmental benefits. Distributed photovoltaic power generation projects have no noise and do not pollute air and water during power generation.

The third is to ease the local electricity consumption to a certain extent. However, distributed photovoltaic power generation has a relatively low energy density, and the power per square meter of distributed photovoltaic power generation system is only about 100 watts. This, together with the limited roof area of ​​buildings for installation of photovoltaic modules, cannot fundamentally solve the problem of power shortages. .

The fourth is to co-exist with electricity generation. Large-scale terrestrial power plants generate electricity by boosting and transmitting power grids, which only operate as power generation plants. Distributed photovoltaic power generation, on the other hand, accesses distribution networks and co-exists with electricity generation, and it is required to be consumed on the spot as much as possible.

Distributed photovoltaic power generation, we say the most, write the most, but users are still busy when the real deal. Some of them are unclear about the location of the power station, and some of them are inconsistent with the process, and they are constantly supplementing materials.······

I am a user. I want to build a home photovoltaic power station. What should I do?

In fact, it is very simple to summarize: Accurately locate your own type of power station, find a professional EPC company to cooperate and let them help.

The first choice is to clarify what kind of power station is built. It is all self-employed, whether it is all on the Internet, or whether it will be used for self-use.

Note: In this case, we must pay attention to, when the user chooses according to their own actual situation, now there is a limit to the total amount of access to the Internet, draw a line. Now we are talking about the most spontaneous or self-interest. It is also actively promoted by local governments to promote distributed development.

What information do you need to apply for a grid connection?

I. Resident account

II. Original and copy of the resident identity card

Third, the copy of the real estate license or housing lease contract

Note: Occupying the roof of public housing, it is necessary to provide written documents certifying the consent of other owners, properties, and residents' committees, and relevant information on the preliminary work of the project, including the design of the rooftop power station, the scheme, installed capacity, and the types of power generation projects.

details:

Note: The industry mainly applies for the local power supply business office and fills in the application form for accessing the distributed power supply project.

At present, the provincial power departments implement the state's preferential policies for solar power generation related regulations, and install and debug on-grid networks until the acceptance is fully implemented. The entire process of grid connection is completely free of charge.

In the above content, we mentioned EPC companies. Here, they added that they are familiar with various process procedures and they are also more professional in system configuration. General users can directly find small EPC companies to do it. This saves a lot of time.
