Correct installation of solar panels

Correct positioning of solar panels is essential for optimum energy production. Non-compliant installations can greatly reduce energy production.

This tutorial is applicable for:

Difficulté : Easy
Nombre d’étapes : 4
Mise à jour : February 2025

Tutorial steps:

Step 1: Floor installation

  • Ground positioning requires the use of the fixing brackets supplied with the kit, in order to achieve the correct inclination.
  • They may not be installed on a roof or used as a pergola.
  • Position your solar panels facing south. Poor exposure will result in a drop in performance.
  • Mount the solar panels using the fixing brackets supplied.
  • The inverter must be installed on the inside of solar panel.
  • An outdoor installation can lead to major inverter failures.
  • Weight the solar panels to stabilize them.

Step 2: Wall installation

  • Wall installation requires the use of the fixing brackets supplied with the kit, to ensure the correct inclination.
  • Make sure you install the solar panels on a clean wall surface in good condition.
  • A wall-mounted installation is slightly less productive than a floor-mounted installation.
  • Position your solar panels facing south. Poor exposure will result in a drop in performance.

Installation takes place in 2 stages.

  • Make sure that the height of the solar panels does not exceed 1m80.
  • Fasten the top bracket using the appropriate fixings for your wall.
  • Fasten the lower mounting bracket using fasteners suitable for your wall.
  • The inverter must be installed on the inside of solar panel.
  • An outdoor installation can lead to major inverter failures.

Example of a non-compliant installation

  • Obstacles in front of the solar panels cause shading and a significant reduction in production.
  • The orientation of the solar panels is incorrect.
  • The solar panels are not all oriented in the same direction, which results in shading and a significant reduction in production.
  • The inverter is positioned on the outside. Watertightness and protection from the sun are impaired.
  • Solar panel behind bars. There will be too much shade, resulting in a significant reduction in production.
  • If there’s vegetation in front of the solar panels, there’ll be too much shade, resulting in a significant reduction in production.
  • The second kit from solar panel is too close to the first kit. The first kit will create a shadow on the second kit.
  • Solar panel placed too high >1m80
  • The roof gutter will create a permanent shadow zone over the solar panels, resulting in a significant reduction in production.
  • Incorrect exposure: the solar panels are permanently in the shade. This leads to a significant reduction in production.
  • Unstable solar panels.
  • Placed on a metal roof, the temperature of the entire kit rises. This leads to a significant reduction in production. Electrical risks are high.
  • Unstable structure
  • The solar panels are not oriented in the same direction. This leads to a significant reduction in production
