Wall-mounted solar panels are an efficient way to generate electricity, especially for those without sufficient roof space. Here are the steps and precautions for installing solar panels on the wall.
Steps:
1. Choose suitable solar panels: When selecting solar panels, you should consider the surface area and angle of the wall to ensure that it can fully absorb sunlight and generate electricity. . Generally speaking, the wall angle should be between 20 and 45 degrees, and the solar panel model should also be selected according to this angle.
2. Choose the appropriate installation location: You should choose the location closest to the power grid for installation to facilitate the return of electricity to the grid.
3. Prepare installation tools and materials: Some necessary tools, such asskateboard nails, oxidized steel screws, etc., and the necessary installation materials, such as aluminum mounting brackets, junction boxes, etc. prepared.
4. Mounting Bracket: The mounting bracket must be installed in a pre-selected location on the wall. Make sure the mounting bracket is parallel to the wall and secure.
5. Install the solar panel: Install the solar panel on the bracket and use steel screws to secure the solar panel to the bracket to prevent it from moving under strong wind pressure.
6. Complete the electrical connection: You can use a junction box to connect the solar panel to the electrical system and ensure high-quality wiring to avoid damage to the panel.
Notes:
1. Before selecting solar panels, you should measure the wall angle and space to ensure that you select the solar panel sizeappropriate.
2. Before installing solar panels, make sure the wall is dry, flat and solid to ensure the mounting bracket is secure.
3. When handling electrical connections, precautions should be taken and safety fuses and cables should be used according to the actual situation.
4. Wall-mounted solar panels are only suitable for walls with solid structures such as brick walls, steel structures and cement walls, and installation should always be carried out in accordance with the design guidelines.
Free installation of solar panels sounds very attractive, but in reality this promotion is based on complex economic considerations. First, although some claims facilities are free, they usually involve a loan. Farmers must invest in photovoltaic energy production equipmentthat, ranging from tens of thousands to hundreds of thousands. For families with better financial conditions, they can choose to buy it themselves and find professionals to install it, but this does not apply to most cases requiring a loan.
Take the example of a farmer in the Nanping Mountains of Fujian. He was attracted by the promotion of “free installation”. However, after the equipment was installed, he found that the actual cost of the equipment was much higher than the normal market price. According to industry insiders, the normal price of this equipment on the market is around 100,000 euros, but he was forced to borrow 200,000. This phenomenon is not uncommon in the photovoltaic installation sector on rural roofs. Installation companies often take advantage of farmers' lack of knowledge about photovoltaics to set high prices and obtain profits.these students.
Therefore, the so-called “free installation” is often a trap that hides expensive loan costs. When deciding to install solar panels, farmers should be careful about these promotions and fully understand the true price and loan terms of the equipment to avoid unnecessary financial losses. When choosing an installation service, it is recommended to find formal channels to ensure transparency of information and avoid falling into the trap of unscrupulous traders.
