What is the optimum tilt angle for photovoltaic panels in Poland?
Solar energy is an increasingly popular source of sustainable energy in Poland, which is linked to the growing interest in the installation of photovoltaic panels. One of the key aspects of designing an effective photovoltaic installation is determining the optimum angle of the panels. It has a significant impact on the efficiency of the whole system and should be adapted to the local geographical conditions and the objectives of the installation.

Photovoltaic panels - what is the optimum angle and positioning?
How we position the photovoltaic panels will have a bearing on the installation's yields in the future. The minimum tilt angle, according to experts, is 15 degrees. However, it is not entirely true that there is one optimum angle of inclination for photovoltaic panels. In Poland angle of photovoltaic panels will depend more or less on the location. South-oriented PV installations in southern Poland will be more efficient with a panel tilt angle of about 30 to about 35 degrees, while for northern Poland the value of the tilt angle for best panel efficiency oscillates between 35 and 40 degrees.
What is the optimum roof pitch for photovoltaic panels?
In many temperate regions, a roof pitch angle of around 30-40 degrees is often considered optimal. This strikes a good balance between producing energy all year round and avoiding too much loss due to too high or too low an angle. There are flat roofs where the panels would have to be laid flat. However, this would translate into them being less efficient. For this reason, for flat roofs as well as those where the angle of inclination proves to be too small, special structures are used which allow the angle of inclination to be adjusted. The idea is also to give the panels the ability to clean themselves. Lingering snow or other dirt on their surface generates shading, which significantly reduces the panels' effectiveness.
What should be the orientation of the photovoltaic panels?
The south-facing orientation of photovoltaic panels will not always be the optimal one. In Poland, an east-west orientation seems to be an equally favourable choice, as it maximises production time. Photovoltaic panels that are oriented to the south start producing energy at high output only at midday, while panels with an alternative azimuth start working just after sunrise. Such a solution is counterintuitively beneficial from the point of view of self-consumption, as the production of electricity is more in line with the building's demand and can therefore be consumed on an ongoing basis.
Orientation of photovoltaic panels and their efficiency
The right orientation has a huge impact on the performance of the entire photovoltaic system. It is a key factor influencing the performance of the installation. Choosing the right orientation depends on the geographical location, the objectives of the installation and individual circumstances. In this situation, it is advisable to consult a company that provides a comprehensive consultancy and installation service for photovoltaic systems to determine exactly the best orientation direction. Optimal positioning can help to produce the maximum amount of electricity, which will contribute to an accelerated return on investment. A properly designed photovoltaic installation can bring many benefits, including savings on energy bills and a reduction in greenhouse gas emissions, an important step towards a sustainable energy future.
