Industrial and commercial rooftop photovoltaic installation process

The process of installing photovoltaics on commercial and industrial roofs can be divided into the following key steps:

1. Project preparation phase

- First determine the installation site, evaluate the scale and benefits of the photovoltaic system, and develop a project plan.

- Obtain necessary permits and approvals, including analysis of site property rights, static investment and operation and maintenance investment, and income distribution.

- Conduct on-site surveys to understand the lighting conditions, building structure, and grid access at the installation site.

2. Design phase

- Combine photovoltaic technology and power demand, and develop a detailed system design plan based on the results of the on-site survey.

- Determine the number and layout of photovoltaic modules, the installation method of brackets, the selection of inverters, etc.

- Perform calculations and simulations of the power system to ensure the stability and reliability of the system.

3. Procurement and construction preparation phase

- Select reliable suppliers to purchase photovoltaic modules, brackets, inverters and other equipment, and conduct quality inspections.

- Prepare the manpower, materials, tools, etc. required for construction.

4. Construction phase

- Install PV modules, erect brackets, lay and connect cables according to the design plan.

- Relevant safety regulations and operating procedures must be followed during the construction process to ensure construction quality and safety.

5. Joint adjustment and commissioning phase

- Connect and configure the inverter, connect and commission the system, test the grid access, etc.

- Ensure that the electrical parameters and performance of the system meet the design requirements, and make necessary adjustments and optimizations.

6. Grid supply review and grid connection phase

- Evaluate and review the safety and compliance of the PV system's access to the grid.

- After the review is qualified, the PV system will be officially connected to the grid and start generating electricity.

7. Operation and maintenance phase

- After the PV system is put into operation, regular operation and maintenance will be carried out.

- Including cleaning and inspection of PV modules, operation monitoring and maintenance of inverters, inspection and maintenance of cables and wiring, etc.

During the entire process, special attention should be paid to the ownership of the roof or site to ensure that the photovoltaic power station is built on a site or roof with clear ownership. In addition, during the installation process, especially when constructing on the roof or special structure, special attention should be paid to waterproofing, anti-corrosion and fixing to ensure the stability and reliability of the system. At the same time, during the entire process, relevant safety regulations and standards should be followed to ensure the safety of personnel and equipment.
