Photovoltaic installations are becoming increasingly popular, which is related to the desire to take care of the environment, but also our wallets. There is probably no doubt in anyone's mind that the use of photovoltaic panels is, after all, cost-effective in the long term. Therefore, if we want to save on electricity, photovoltaics must appear in our house. It is best to start preparing this project at the stage of choosing a plot of land and a house design. Although, of course, we can also easily apply this solution to existing buildings. Photovoltaic panels can be installed on virtually any roof - flat, pitched, felt, tiles or sheet metal. However, by considering several aspects at the design and construction stage of the house, the use of a photovoltaic installation will be cheaper, more efficient and the need to interfere with the house (e.g. façade) during the installation of photovoltaics will be minimised.

Choose the right plot of land

When choosing a location for our house and a photovoltaic installation on its roof, we must ensure that it is not shaded by other elements. This includes, for example, tall trees or buildings in the vicinity. We should remember that even the shading of one of the panels may reduce the efficiency of the entire photovoltaic installation and thus reduce the flow of electricity. So if you are planning to invest in solar panels, pay particular attention to their location.

Photovoltaic panels and house design

When it comes to the siting of photovoltaic systems, a new house is the ideal place to install them. In such a situation, we can plan their appropriate placement already at the design stage of such a building. The most important factor in this case is the type of roof and its orientation with respect to the sun, but also the inclusion in the design of an additional ventilation chimney and technical ducts where the cables will be located, as well as conduits for the solar cabling and adequate space for technical equipment.

For photovoltaic installations such as solar panels, the type of roof of the house is particularly important. It must be of an appropriate size and ideally have a fairly simple design. A mono-pitched, gabled or flat roof are the most reasonable options. Ideally, the photovoltaics will be installed on the south-facing slope of the roof, so it is good if there are no roof windows or chimneys or antennas that can shade the installation components.

Professional installation

When preparing to use photovoltaic panels in our home, the construction of the roof is of great importance, but it is equally important to choose a reputable company to design such an installation and to install it. It is worth deciding on the services of experienced professionals who have adequate knowledge of photovoltaics. This way, you can be sure that the installation will be installed in a way that will allow it to work efficiently for many years.

Summary of key aspects:

1. Roof direction and angle. Ideally, the panels should face south tilted to a maximum of 45 degrees east or west. The optimum roof angle is around 30-40 degrees. The maximum efficiency of the system will then be achieved.
2. If possible, it is advisable to avoid bay windows and chimneys on the side of the roof where the photovoltaic modules are to be installed. Ideally, the roof slope should be clear of elements that could shade it.
3. Preparation of cable routes. Two cable routes should be prepared, for example, in the form of a pilot line. One route will bring the cables from the roof (from the ridge) to the place where the inverter will be mounted - for example, at the switchboard or power socket in the garage. This conduit should be approximately 50mm in diameter. The second route will be to run the earthing cable - along the elevation from the roof to the ground. In this case, a 20mm diameter conduit concealed in the façade will be sufficient. This avoids any interference with the façade in a newly built property and avoids additional drilling between rooms inside the building.
4. Electric heating. If you are planning electric heating (heating mats, heat pump), the roof slope should allow for an installation of approximately 9-10kW, i.e. a minimum of 60m².
