1. Choose a good product: Before installation, be sure to 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 business because of the cheap carbon.
2. Installation orientation: It is best to install the PV power station towards the south. Because we are in the northern hemisphere, the power generation board faces the south with the highest power generation, and the solar radiation is also the best. Especially in summer, after noon, the solar radiation is the strongest. Time, when the direction is positive southward, the maximum power generation will be obtained; likewise, the maximum solar radiation direction in winter is slightly eastward. Therefore, as long as your roof is within ±10° of the south, the power generation is not too high. Big influence.
3. Eliminate shadow obscuration: Not all south-facing roofs can be fitted with PV modules. We have to consider that the surrounding trees and other buildings will not block the PV modules. If there are obstruction sources, these obstruction sources should be removed. Then consider replacing the installation site.
4. Roof weighing: The photovoltaic system should be built on the roof. If the roof's carrying capacity can't meet the photovoltaic construction, this project is not established.
5. Installation angle: The PV array can be installed at the optimal angle to obtain the maximum power generation.
6. Installation and commissioning: Installation requires qualified PV personnel to install. The serial-parallel connection after the installation of the battery components is best done after the sun goes down, avoiding high-voltage electric shock, and at the same time doing lightning protection and grounding work. Wind grade, northern users should also pay attention to the snow resistance level.
to sum up
Photovoltaic power plants are not free to install and can get good returns. After installing PV power plants correctly, they need to use a little bit of snacks to protect them. Only in this way will PV modules bring us considerable returns. At the same time, the life of household PVs For 25 years, it can help the people to obtain sustainable income, which can improve the life of farmers to a certain extent. 'Photovoltaic power generation to improve the quality of life' is about to become a reality.
