In-roof solar panels – the aesthetic and smart solution
A photovoltaic system is more in demand than ever in times of energy revolution and energetic renovation. There are many different technical solutions and concepts, each of which has its own advantages. The solution with in-roof solar modules is particularly advantageous. This variant is more aesthetic because the solar modules in the in-roof solution are installed directly in the roof and thus form a homogeneous unit and surface with the complete roof covering. However, this model is not suitable for all roof types. You should inform yourself in advance.
What are in-roof solar panels?
The in-roof solar modules are a photovoltaic system that is part of the roof covering. The individual in-roof solar modules also replace the otherwise used roof tiles. Thus not only higher costs arise, but also savings, because conventional tiles are saved.
What are in-roof solar panels used for?
In addition to generating solar energy, in-roof solar modules also perform the functions of a regular roof covering. Therefore, there are also special requirements and structural restrictions when using this in-roof solution. For cost reasons alone, this variant is particularly suitable for new buildings or for renovations where the existing roof covering has to be completely renewed anyway. In addition, it is often not possible to install existing buildings indoors, so that only the standard on-roof installation of the solar modules is possible. This in-roof variant is also not technically possible for pure sheet metal roofs and bitumen roofs. However, tiled roofs are ideal for in-roof solar modules. The shape of the roof can also decide whether such a solution is possible. in-roof solar modules are only suitable for pitched roofs that are sufficiently large to face the sun. Also the inclination angles for the unproblematic discharge of rain water must be particularly considered.
What are the advantages and disadvantages of in-roof solar modules?
An important advantage of in-roof solar modules is the aesthetic impression. An even surface with solar modules that are integrated into the roof is certainly more visually attractive than a photovoltaic system as on-roof installation, which always remains a foreign object. The functional values of in-roof solar modules are a clear advantage. In fact, the modules often achieve up to 13 % more yield in real operation than planned. In addition, the modules designed and built in the EU have a 25 year linear warranty. In addition, there is the excellent performance even under poor lighting conditions. In addition, professionally installed solar modules can completely take over the protective and sealing effect of a conventional roof covering. A disadvantage are the higher assembly and material costs, because the in-roof solar modules usually have to take over the function of the classical roof covering regarding protection and sealing of the roof. These costs can be neutral with a new building, because a roof covering must take place anyway. An essential advantage is the higher stability, because the photovoltaic system is distributed evenly over the entire roof in the form of modules laid like roof tiles. This considerably reduces the forces that can act on individual modules. With on-roof installation, on the other hand, the important supports of the system are often centrally exposed to wind and weather at a few points. A disadvantage is the loss of performance due to difficult cooling of the individual solar modules. With a rooftop solution, cooling is more efficient. The higher costs are mainly due to the production of the protective functions of the modules when they have to take over the function of bricks. For new buildings or a complete roof renovation, these costs can be neutral. With the right planning, the solution with in-roof solar modules allows you to save both installation costs and energy savings during ongoing operation.
