Installation and anchoring of solar panels
The installation of solar panels is a fundamental process for harnessing solar energy and converting it into electricity for homes or industries. It involves a series of technical steps that ensure the proper installation and functioning of the solar panels.
From roof preparation to the final electrical connection, each stage of the installation is designed to optimise solar energy capture, ensure the durability of the system, and maximise savings on electricity bills.
1. Installing the structure for solar panels
The first step in solar panel installation is the preparation and placement of the structures that will support the panels. This process begins with measuring the roof to ensure that the structures fit perfectly. Holes are then drilled into the roof, which are sealed with chemical anchors and waterproof paint to prevent leaks. Next, screws are inserted, which will serve as anchors for the aluminium structures.
The type of structure used will depend on the specific installation requirements. For example, if the installation is on a flat roof, the structure must provide the necessary tilt for the modules to maximise their efficiency.
With the structures correctly installed, the solar panels are then mounted onto them. It is essential that this step is carried out with precision to guarantee the stability and safety of the system.
2. Anchoring solar panels to the roof
A crucial part of the process is the anchoring of solar panels to the roof. This step ensures that the aluminium structures supporting the solar panels are firmly secured, thus withstanding weather conditions and keeping the panels in place.
Depending on the materials from which the roof is made, the method of anchoring the panels will vary.
How to secure solar panels on a tiled roof
In this case, the first step is to assess the condition of the tiles. If any are broken, they should be replaced to ensure they can support the structures and the additional weight of the panels.
To mount the supports, it is necessary to temporarily remove some tiles in the areas where the anchors will be installed. This allows access to the roof’s supporting structure (the rafters).
Once the anchors are in place, the tiles are replaced in their original position, ensuring they fit correctly around the supports. In some cases, it may be necessary to cut or modify the tiles to accommodate the anchors without compromising the roof’s waterproofing.
Anchoring solar panels on a wooden roof
As with any installation, it’s crucial to inspect the wooden roof to ensure it is in good condition. For a wooden roof, the anchors must be robust and specifically designed for wood. The most common are heavy-duty screws or bolts, which are inserted directly into the rafters.
It’s essential that all holes drilled into the roof are sealed to prevent water leaks that could damage the wooden structure. We will use a silicone sealant or a waterproofing compound to seal the edges of the anchors and the drilled areas.
3. Location and installation of the inverter
The inverter is the device responsible for converting the direct current generated by the solar panels into alternating current, ready to be used in the home. Choosing the location of the inverter is crucial and must consider two main factors:
- Proximity to the solar panels: Placing the inverter as close as possible to the solar panels helps optimise solar energy production by reducing cable losses.
- Internet connection: The inverter should be placed in a location with a good internet connection, as it will constantly transmit energy generation data. This data will be connected directly to a mobile application, allowing users to monitor their energy production in real-time.
4. Connection to the main electrical panel
The final step in the installation of solar panels is the electrical connection. The inverter is connected to the household’s main electrical panel, allowing all the energy generated by the solar panels to be used for the home’s electrical consumption.
At this point, the installation of the solar panels would be complete. The next important step is the legalisation of the solar system.
