The installation method of the photovoltaic power generation rack is as follows:
1. Preparation work: Before installation, the installation area should be cleaned to ensure that there is no debris or obstructions. At the same time, the position of the support must be measured and marked.
2. Install the foundation: According to the design and support requirements, dig foundation holes in the installation area and pour concrete according to the design requirements. Wait for the concrete to dry and harden.
3. Install the support column: According to the design requirements, insert the support column into the foundation hole and use a level to adjust to ensure that the column is vertical.
4. Attach the support columns: Use bolts or expansion bolts to attach the support columns to the foundation. Make sure the bolts are tight and use a wrench or wrench to scorrect error.
5. Install the beams and supports: According to the design requirements, install the beams and supports on the support columns. Make sure the beams and supports are securely connected to the columns.

6. Install the photovoltaic panel bracket: According to the design requirements, install the photovoltaic panel bracket on the beams and supports. Make sure the supports are securely connected to the beams and supports.
7. Adjust the angle of the bracket: According to the design requirements of the photovoltaic power generation system, adjust the angle of the bracket to maximize the utilization of solar energy.
8. Install the photovoltaic panel: Install the photovoltaic panel on the bracket and use screws or clamps to secure it to the bracket.
9. Connect the cables: Connect thecables from the photovoltaic panels to the inverter or battery, making sure the connection is secure.
10. Inspection and Testing: After installation is complete, perform inspection and testing to ensure the bracket is firmly installed and the PV panels are functioning properly.
It should be noted that the installation of photovoltaic power generation racks requires professional installers to ensure safety and efficiency. At the same time, specific installation methods may vary depending on different photovoltaic power generation systems and design requirements. Therefore, before installation, it is best to consult a professional PV power generation system supplier or installation company for accurate installation advice.
Is it possible to use stone pillars pto install photovoltaic panels on the roof?
1 If the 100 square meters can be used, one system maximum. of 15KW can be installed. However, it is impossible to use all of this surface area. Generally, if it is a tile roof, only the south half will be used. If it is a flat cement roof, you will need to leave some space in the front and rear rows of solar panels. to avoid any projection on the rear solar panels. Basically half the area can be used, so let's assume 8 kW.
2. Grid-connected power generation is converted to alternating current, i.e. AC 220V/380V. Grid-connected power generation does not need to consider the problem of household load, because the The electricity produced is directly connected to the city's electricity, and the electricity you use is then given priority to solar energy if the productionction of solar energy is not significant enough. , the city power will directly supplement it.
Detailed information:
Silicon atoms have 4 outer electrons. If atoms with 5 outer electrons, such as phosphorus atoms, are doped with pure silicon, they become an N-type semiconductor; if 3 atoms are doped with pure silicon, the atoms; with external electrons, such as boron atoms, form a P-type semiconductor. When P-types andN are combined, a potential difference is formed at the contact surface, thus becoming a solar cell. When sunlight hits the P-N junction, current flows from the P-type side to the N-type side, forming an electric current.

Feasible.
Using abutments is preferable, but it is labor intensive and time consuming. The cement abutment requires more than a week of curing and curing time. The support can only be installed afterwards. the cement pier is completely hardened.
Photovoltaic power generation systems can be installed on the roofs of bungalows, tile-roofed houses and colored steel tile-roofed houses. They are all specially designed and have corresponding construction plans. The pillars are calculated and personalized after preliminary weighingu roof. At the same time, solar panels also play the role of thermal insulation in summer and heat preservation in winter.
Safety of photovoltaic power generation:
The equipment lines of the photovoltaic power generation system have overload protection functions. When abnormal voltages such as lightning strikes occur, they will automatically shut down and disconnect. there is no question of security.
The surface of the photovoltaic modules is made of super shock-resistant tempered glass. Generally, the natural climate is difficult to damage photovoltaic panels in thunderstorms, hail and typhoons in the south. and in the northwest where there is a lot of sand and flying rocks, the solar panels will not be damaged and will remain durable.
