Many people think that solar panels can only be installed on the roof of a house while it is quite possible to install them in your garden!
We will see the advantages and disadvantages of installing photovoltaic panels in a garden.
What type of solar panels in a garden?
It exists two types of solar panels possible for installation in a garden we will see in detail the two types of solar panels that you can install in a garden
Thermal solar panels
The thermal solar panels operate by using the sun’s heat to generate electricityhot water or steam. This type of solar panel is less expensive than photovoltaic panels, but they are also less efficient.
Solar thermal panels are a good option if you live in a sunny climate and if you are not looking for electrical self-sufficiency.
Photovoltaic solar panels
The photovoltaic solar panels are more expensive than thermal panels, but they are also superior performance. Photovoltaic panels work by converting sunlight into electricity.
This type of solar panel is perfect if you want to produce a significant amount of energy. However, remember that photovoltaic panels require more maintenance than thermal panels.
The installation of solar panels on the ground is not very complicated provided you respect the three commandments of solar:
First step: choose your orientation
The first step is to choose the orientation of your solar panels. Ideally, they should face south, but that’s not a requirement. East, southeast, southwest, or even west can do just fine. On the other hand, it is not recommended to choose other orientations.
Step Two: Avoid Shadows
When installing your modules, be very careful not to find yourself in a dark area. To avoid this, be sure to check for shadows cast by trees, buildings, or other objects throughout the day.
Third step: Place your modules in an open space
Once you have chosen the orientation and made sure that there are no shaded areas, place your modules in an open space to make it easier for you to maintain the area, especially if the panels are installed in a grassy area you will need to mow or clear brush regularly.
Careful planning and attention to detail are essential to ensure your ground mounted solar panel system delivers.
Installation of solar panels on a garden shed
If you are considering installing solar panels on your garden shed, there are a few things to keep in mind during the installation process.
- Make sure your shed roof is in good condition and can support the weight of the solar panels.
- Be sure to consult a professional installer who can help you determine the best location for your panels and ensure they are installed correctly.
- Make sure all exposed electrical connections are properly sealed and protected from damage that could be caused by the weather.
What permits are required for solar panels in my garden?
If you are considering installing solar panels in your home, one of the first questions you will ask yourself is whether or not you need planning permission. The answer to this question depends on several factors, including the height and power of the solar panels, as well as the location of your home.
Building permit for solar panels: 3 kWp or less
In most cases, you will not need planning permission for solar panels if the following three conditions are met:
- The installed peak power is less than 3 kWp (kilowatt-peak).
- The height of the structure, panels included, is less than 1.80 m.
- The accommodation is not located in a protected area
However, please note that even if you do not need a building permit, you may have to file a preliminary declaration of works with your municipality. Please check with your municipality to find out if this is the case.
Building permit for solar panels over 3 kWp
If any of the above three conditions are not met, you will need to obtain planning permission for your solar panels. In some cases, you may also be required to file a environmental impact statement.
Again, please check with your municipality to find out what is required in your specific case.
| Height of the structure. | Power in kilowatt-peak | construction area | Permission |
| Lower than 1.80m | Lower than 3 kWp | Not protected | No permission needed |
| Superior 1.80m | Prior declaration of works | ||
| All sizes | Between 3 and 250 kWp | ||
| greater than 250 kWp | protected or not | Building permit | |
| less than 3 kWp | Protected | Statement | |
| Higher 3 kWp | Building permit |
