Photovoltaic power generation refers to the direct conversion of solar radiation into electricity, and it is currently the mainstream of solar power generation. With the support of relevant policies from local governments, rural photovoltaic distributed power generation projects have achieved significant development in recent years. Today, we will learn about the application materials and procedures for individuals applying to install household photovoltaic power generation systems, as well as the precautions for installation.
Individuals applying to install household photovoltaic power generation systems need to provide the agent's ID card and a copy, household registration book, property ownership certificate, and other legal supporting documents for the project.
I. Application materials and procedures for household photovoltaic power generation installation:
1. Distributed power generation grid connection application form: Go to the power grid company's application office, find the person in charge, and submit the application form (they have standardized documents for you to fill out).
2. Original and photocopy of the owner's ID card (both sides copied onto one sheet of paper, signed and fingerprinted by the owner).
3. Original and photocopy of the authorized representative's ID card (both sides copied onto one sheet of paper, signed and fingerprinted by the representative) and original power of attorney from the homeowner (required if the applicant is not the homeowner).
4. A photocopy of the homeowner's household registration booklet (signed and fingerprinted by the homeowner).
5. A photocopy of the property ownership certificate for the building site (or a certificate of house use issued by the township or higher-level government) or the original lease agreement.
6. A photocopy of the electricity invoice (signed and fingerprinted by the applicant)
7. A photocopy of any bank card (both sides copied onto one sheet of paper, signed by the applicant, and with a fingerprint).
8. Copies of equipment documents (solar panels and inverters; the submission deadline varies by region).
II. Precautions for installing residential photovoltaic power generation systems:
1. The grid connection voltage of a distributed photovoltaic system is mainly determined by the installed capacity of the system. The specific grid connection voltage needs to be determined according to the grid company's approval of the grid connection system. Generally, residential systems use AC220V to connect to the grid, while commercial systems can choose AC380V or 10kV to connect to the grid.
2. The tilt angle of a photovoltaic array is generally determined by the latitude of the installation location.
3. Since the main factor affecting photovoltaic power generation is the amount of sunshine, photovoltaic modules should be installed facing the direction with the most sunlight. Different installation angles also affect the power generation of photovoltaic modules.
