Photovoltaics is one of the most dynamically developing sectors using renewable energy sources. A key element of every photovoltaic installation is the photovoltaic panel mounting systems, which determine the stability, safety and efficiency of the entire investment. Choosing the right system not only optimizes energy production, but also reduces operating costs. Below are the characteristics of individual solutions and their impact on the efficiency of photovoltaic installations.

Installing photovoltaic panels on a vertical wall and energy efficiency
Before we get to the point, let us remind you that there are various PV mounting structures available on the market, adapted to the specifics of the mounting location:
Flat roof systems
- Ballast structures that do not require drilling into the roof;
- Adjustable tilt angles increase the efficiency of the photovoltaic installation.
Systems for pitched roofs
- Easy to install thanks to mounting rails;
- Perfect for residential buildings.
Ground systems
- Stable and durable solutions for open spaces;
- It is possible to install larger numbers of photovoltaic panels, making the investment more profitable.
Installing a photovoltaic system on a vertical wall of a building is a solution that attracts attention due to the space savings and aesthetics. Although this method of installation is less popular than installations on the roof or ground, it can be beneficial in certain conditions.
Installing photovoltaic panels on the wall – benefits:
- It allows you to use vertical surfaces, especially where there is not enough space for installation on the roof or ground.
- Protects the panels from accumulating snow or leaves, which affects their efficiency.
When deciding to install photovoltaics vertically, you have to take into account certain limitations. Namely, photovoltaic panels mounted in this arrangement are susceptible to a decrease in power, because the angles of sunlight are less optimal . To increase efficiency, systems with adjustable panel orientation should be used.
When is it a good idea to install photovoltaic panels on the ground?
Photovoltaic installations located on the ground are an ideal solution for investors with a large space. Ground structures allow for precise adjustment of the angle of inclination and orientation of photovoltaic panels, which allows for the production of electricity on a wider scale.
Advantages of ground-mounted photovoltaic installations:
- Freedom to choose the mounting location and position the panels at the optimal angle for maximum performance.
- Easy access to the installation, which facilitates maintenance and cleaning.
The disadvantage of this solution is the higher installation costs resulting from the need to use solid foundations or ground screws, which ensure the stability of the entire structure. It is worth noting, however, that ground-mounted photovoltaics are more flexible and better meet the needs of larger industrial installations.
Advantages and disadvantages of installing a photovoltaic system on the roof of a house
Installing photovoltaic panels on the roof is the most frequently chosen solution for residential buildings, especially those that use off-grid installations, operating solely within the home electrical network. Using the available roof surface allows you to save space on the property and effectively reduce investment costs.
Investors can choose from:
- Systems for mounting photovoltaic panels on flat roofs;
- Systems for mounting photovoltaic panels on pitched roofs.
Flat roof structures offer great flexibility in panel positioning, which makes the photovoltaic installation more efficient . Ballast structures are most often used, which do not require interference with the roof structure. This makes them an ideal solution for buildings where maintaining the tightness of the surface is important.
For sloping roofs, sloping roof structures are used. In this case, the photovoltaic installation is based on structures adapted to the angle of the surface. Such systems are usually mounted on special rails, which ensures stability and even load distribution.
Advantages of a photovoltaic installation on the roof:
- Lower installation costs compared to ground structures.
- Possibility of integrating photovoltaics with existing building infrastructure.
The disadvantages include limited installation space and the need to adapt to the existing structural conditions of the roof.
By installing photovoltaics, we are investing in the future of obtaining electricity from renewable energy sources. Choosing the right mounting system affects the efficiency and costs of the entire investment.
