PV power plants are now developing in many areas. It can be said that distributed photovoltaic power plants are very common. No matter where you go, you can see from time to time that photovoltaic power plants have been installed on the roofs along the roadside. Today, we are going to visit and install photovoltaic power stations. The correct method, I hope everyone will see this article and correct all the mistakes.
Correct installation of photovoltaic power plant
1, choose a good product: Before installation, we must choose a good product, a good business, after all, the quality of the product is the essential guarantee of the life of the power station. Do not choose some unknown businesses because carbon is cheap.
2. Installation orientation: The installation of PV power plants is preferably installed in the south, because in the northern hemisphere, the power generation panel has the highest power generation and the solar radiation is also the best. Especially in the summer, after the noon is the time when the solar radiation is the strongest, when the direction is positive south to the west, will get the maximum power generation; Similarly, the maximum solar radiation in winter is slightly eastward. Therefore, as long as your roof is within ±10° south, there will be no significant impact on power generation.
3. Exclude shadows: Not all south-facing roofs can be installed with photovoltaic modules. We must consider that the surrounding trees and other buildings will not block the PV modules. If there are obstruction sources, these obstruction sources should be cleared if they cannot be removed. Then consider replacing the installation site.
4. Weighing of roof: The photovoltaic system shall be built on the roof. If the carrying capacity of the roof cannot meet the requirements of photovoltaic construction, this project is not established.
5. Installation angle: The PV array can be installed at the best angle to obtain the maximum power generation.
6, installation and commissioning: installation requires qualified photovoltaic personnel to install. After the battery module is installed, the serial and parallel connection cables should be completed after the sun goes down, avoiding high voltage and electric shock, and doing lightning protection and grounding work. In addition, attention should be paid to the wind resistance rating of the bracket. Northern users should also pay attention to the anti-snow rating.
Photovoltaic power plants are not free to install and they can get good returns. After properly installing photovoltaic power plants, they need to take a little dim sum to protect them. Only in this way can PV modules bring us considerable returns. At the same time, the useful life of household photovoltaics is as long as 25 years, which can help ordinary people to obtain continuous income, and to a certain extent can improve the lives of farmers. "PV power generation improves quality of life" is about to become a reality.
Lear Solar developed a photovoltaic cleaning robot specifically for distributed photovoltaic power plants. It is used for photovoltaic panel cleaning, intelligent full automation, and increased power generation.
