Photovoltaic panel installation process:
1. Site selection
The sun must be able to shine all year round (for example, on the roof of a building).
2. Make the foundation
After determining the azimuth angle according to the geographical location, combine the shape of the photovoltaic module support to make the support foundation (such as a concrete base). .
3. Install the bracket
Install and secure the bracket to the foundation, and adjust the azimuth and elevation angles.
4. Install the photovoltaic modules
Install and fix the silicon crystal solar panels to the support according to the pre-designed plan.
5. Electrical connection
Firstly, the electrical grounding of the bracket and photovoltaic modules should be carried out, and then the wiring of each silicon crystal solar panel should be connected according to the design.
6. Debugginge electrical
After the wiring of the silicon crystal solar panels is connected and checked, connect the inverter, battery and other equipment for common debugging.
Precautions for installing photovoltaic solar panels
1. Do not install photovoltaic solar panels in shady places such as trees and buildings. Do not approach open flames or flammable materials. The assembly structure must be able to adapt to environmental requirements. Please select appropriate materials and anti-corrosion treatments. Use reliable methods to install components. If components fall from a high altitude, they may cause damage or jeopardize the safety of people and property. Do not disassemble, bend or hit components with hard objects. Avoid walking on components.
2. Use spring washers and washersplates to attach the photovoltaic solar panels to the support. Ground the panel assembly appropriately based on the site environment and the structural condition of the mounting bracket.
It is always good to install photovoltaic energy production on roofs. If you install solar panels on the roof, you can efficiently use solar energy to generate electricity and save electricity. The state now provides subsidies for the installation of power strips. With solar power, we generally use less electricity, saving electricity for your home. Installing photovoltaic power generation on the roof is relatively simple, generally speaking, it can be installed by a few workers in half a day.
1. Rooftop photovoltaic power generation is a mature technology that involves instainstall solar panels on top of the building and combine the existing building with the photovoltaic system. Use existing buildings efficiently without taking up additional land resources. It can generate electricity locally and consume electricity nearby, thereby reducing transmission losses. Photovoltaic power generation occurs during the peak electricity consumption period during the day, which can effectively alleviate peak electricity demand. The state actively promotes the possibility of producing electricity if solar panels are installed. Unused electricity can also be sold to the State Grid and benefit from corresponding subsidies. It can be connected to the electricity grid, which means you need to install two electricity meters in your home, one for electricity supplied by the electricity company and the other for electricity produced bythe solar panels.
2. The construction of a photovoltaic plant requires support, which must be built on the roof or in an open space. Property rights to the roofs of urban buildings belong to all owners. If someone wants to build a photovoltaic plant on the roof of a building, they must not only obtain the consent of all the owners, but also obtain the consent of all the owners. It involves property management companies, urban management and other units. Many people in the city want to pretend, but it is not easy to do so. When installing, professional installers will design and install it reasonably according to the local climate. The photovoltaic plant will have no problem withstanding strong winds of magnitude 8 to 10.
3. Since the photovoltaic power generation system requiresdrilling holes in the roof during installation, if installed or handled improperly, it is easy to damage the roof, leading to water leakage accidents, mold, etc. ., and higher maintenance costs in the future. One of the most obvious disadvantages of installing solar PV power generation on your roof is that PV power generation destroys the waterproof layer of the house. The above is the answer to the question whether it is good or bad to install photovoltaic power generation on roofs and why.
