Along with the development of the photovoltaic industry in the past few years, many domestic traditional companies began to focus on the field of new energy. But most of the enterprises into the field of photovoltaic industry found that not everywhere gold, everywhere opportunities, since 09 a large number of old photovoltaic equipment manufacturers basically disappeared or transferred to foreign markets, but still can not resist more and more traditional manufacturing enterprises to this "seemingly beautiful" circle squeezed.
At present, distributed photovoltaic is very hot, I believe that the development trend of this large we are all witnessed, can see.
Distributed photovoltaic has great advantageous features, you all know?
First, the output power is relatively small. Generally speaking, a distributed photovoltaic power generation project capacity within a few kilowatts. Unlike centralized power plants, the size of the PV plant has very little impact on the efficiency of power generation, and therefore on its economics, the return on investment of small PV systems is not lower than that of large ones.
Second, the pollution is small, the environmental benefits are outstanding. Distributed photovoltaic power generation project in the power generation process, there is no noise, and will not produce pollution to air and water.
Third, it can alleviate the local electricity tension to a certain extent. However, the energy density of distributed photovoltaic power generation is relatively low, the power of each square meter of distributed photovoltaic power generation system is only about 100 watts, coupled with the limited area of the building roof suitable for the installation of photovoltaic modules, can not fundamentally solve the problem of electricity tension.
Fourth, it is possible to generate and use electricity. Large ground power plant power generation is boosted access to the transmission grid, only as a power station and operation; and distributed photovoltaic power generation is connected to the distribution network, power generation and electricity coexistence, and requires local consumption as much as possible.
Distributed photovoltaic power generation, we say the most, write the most, but the user in the real time to do still busy anxious. Some are power station positioning is not clear, some is the process is not straightened out, and constantly supplemental materials ------
I am a user, I want to build a home photovoltaic power station, how do I do?
In fact, summarized down is very simple: accurate positioning of their power station type, find a professional EPC company to cooperate, let them to assist.
The first choice is to clarify what kind of power station you are building, whether it is all for your own use, all online, or self-generation and surplus power online.
Note: Here we have to pay attention to is that the user in the selection of their own actual situation, now the full amount of Internet access domestic has a limit, draw a boundary. Now we are talking about the most or self-generation, residual power online this model. It is also the local government to promote the development of distributed actively led to the estimate.
What information do you need to apply for grid connection?
A. Resident account book
Two, the original resident ID card and a copy
Three, a copy of the property certificate or housing lease contract
Note: Occupy the roof of public housing, you need to provide written documents from other owners, property, neighborhood committee to agree to the proof, information related to the preliminary work of the project, including the design of the rooftop power station, program, installed capacity and the type of power generation project.
Details.
Note: The owner has to apply to the local power supply business office and fill in the application form for distributed power project access.
At present, the provincial power departments implement the national preferential policies for solar power generation related regulations, and the whole process of grid-connected installation, commissioning, until acceptance and official activation and grid connection is completely free of charge.
We mentioned EPC companies in the above content, here to add, they are familiar with the process procedures, for the system configuration is also more professional. General users can directly find a small EPC company to do. This can save a lot of time.
