How to install solar panels yourself ?

After purchasing solar panels, many people want to do the installation themselves to save money. If you are familiar with using basic tools such as hammers, screwdrivers, nails, and electric drills, the following steps will help you install solar panels on your roof.

Step 1: Determine the installation area
First, choose an area with plenty of sunlight as the installation site. Make sure there are no buildings, trees, or other objects in the area that will block the sunlight, so that the absorption of solar energy can be maximized.

Step 2: Determine the tilt angle
To ensure optimal efficiency, it is important to set the tilt angle of the solar panel correctly. Depending on your geographical location, you can use the following formula:

Northern Hemisphere: Winter Tilt Angle = Latitude + 15°; Summer Tilt Angle = Latitude - 15°.

Southern Hemisphere: Winter Tilt Angle = Latitude - 15°; Summer Tilt Angle = Latitude + 15°.

For example, if you live in the Northern Hemisphere and the latitude is less than 25°, the winter tilt angle is about 40° and the summer tilt angle is about 10°.

Step 3: Start the installation
Use a stud finder or look at your house blueprints to locate the rafters on your roof. Then install brackets on the rafters, spaced approximately four feet apart. Make sure to choose the right location when drilling holes in the rafters and secure the brackets with steel bolts. Remember to seal under the bolts to maintain an airtight seal.

Step 4: Securing the solar panel
Next, mount the panel to the bracket. Most solar panels will come with easy-to-fix connectors; if not, make sure the screws you use are tight enough. Keep the panel at least a quarter foot off the roof to ensure good airflow, which will increase its efficiency.

If you want to simplify the installation, consider using Werchtay's bracket mount. This system does not require drilling, does a good job of securing the panel, and can lift the panel to the optimal height to ensure good airflow and maintain temperature, thereby optimizing the panel's performance.

Step 5: Connect to power
After you have completed the installation of the solar panel, be sure to seek professional help to connect the panel to your home power supply to ensure a stable power supply.

Tips for installing solar panels
Knowing how to install solar panels is only the first step to a successful installation. The following points are also important:

Main Components
Solar panel mounting systems usually include three main components: roof attachments (bracket systems), mounting rails (to secure the panels), and module clips (to further secure the panels). RCC mounts are very popular in residential and commercial settings because they reduce wiring and reduce the loss of DC power. But make sure they are well sealed to prevent leaks.

Choosing Materials
When choosing mounting materials, you can consider the following factors:

Weight: When it comes to rooftop mounting, the weight of the material is key. Common materials include steel, aluminum, and stainless steel, with aluminum being lightweight and easy to adjust.
Durability: The material must be strong enough to withstand the harsh weather such as wind, rain, snow, and UV rays. At the same time, if you are in a humid or coastal area, the material must also be rust-proof and corrosion-resistant.
Environmental protection: Choosing sustainable materials to reduce your carbon footprint is also a very important consideration.
By following these steps and suggestions, you can successfully install solar panels and enjoy the benefits of green energy.
