The installation of the module on the roof follows a detailed and safe process, ensuring efficiency and protection. On clay tile roofs, some tiles are removed to fix supports at appropriate points, creating the support base. On metal roofs, the support is directly screwed onto the metal surface, providing stability and sealing against water infiltration.
In this article, we will explain in more detail how the installation is performed, why it is necessary, and offer suggestions for those seeking to install a solar system.
Why Hire Professionals for System Installation?
Photovoltaic installation requires specialized technical knowledge. Although the process may seem simple, it involves critical steps that, if performed incorrectly, can compromise system performance or even cause accidents. Therefore, hiring a qualified company or professional is essential to develop the project, identify the best location for the panels, and ensure safe execution. Furthermore, to connect the system to the electrical grid, it is necessary to obtain authorization from the local energy distributor, a task that only engineers or electrotechnicians are qualified to perform.
Additionally, roof installations require strict use of safety equipment due to the risks associated with working at heights. Therefore, specialized professionals follow all technical standards, ensuring that the system functions properly.
Equipment Required for Solar Energy Installation
The photovoltaic installation kit includes the following main items:
- Circuit breakers and other electrical materials.
- Solar panels;
- Solar inverter;
- Mounting structures for modules;
- Specific cables and connectors;
We will discuss the steps below:
Step-by-Step Guide to Photovoltaic Installation
The process of installing a photovoltaic module on a roof involves various carefully planned steps:
1. Site Preparation
The installation team climbs onto the roof and draws the previously planned layout, indicating the exact position of each photovoltaic module. This organization ensures that the system maximizes solar incidence.
2. Support Fixation
On clay tile roofs, installers remove tiles at indicated points and screw supports directly into the structure. On metal roofs, supports are fixed more simply without the need for tile removal, ensuring protection against water infiltration.
3. Rail Installation
Pre-fabricated aluminum rails are fixed to the supports to create the base where modules will be installed. This step is fundamental to ensure that panels remain firm and properly aligned.
4. Solar Panel Assembly
With the rails installed, modules are fixed onto them. Next, electrical cables are connected, interconnecting the panels and ensuring energy flow.
5. System Connection to Inverter and Electrical Grid
In the final step, installers connect modules to the solar inverter, which converts generated energy into usable electricity. The inverter is then integrated into the residence or company's electrical grid. After these connections, the system is ready to generate energy, immediately reducing electricity costs.
Benefits of Investing in Solar Energy
Installing photovoltaic modules provides significant savings. Although the electricity bill does not reach zero cost, as there are still charges to the distributor, the reduction can exceed 90%, depending on the contracted project. Additionally, the system is sustainable and contributes to environmental preservation.
