The transition towards sustainable energy has been underway for some time. “Renewable” is in fact the watchword of this decade, especially as regards the intelligent use of alternative energies. An evolution which also finds its place within the domestic walls. In fact, photovoltaic systems at home reduce energy costs and pay off in terms of investment. The first question to ask, however, is whether the property has the appropriate requirements.

Is the site suitable for installing a photovoltaic system? You need to analyze the presence of radiant solar energy on your site. Global solar radiation depends on the season and region.

Is my home suitable for installation? The conditions of your home must be considered, in particular the slope of the roof. The optimal angle varies throughout the day and year depending on the position of the sun. An inclination between 27 and 35 degrees is recommended to obtain optimal performance.

An addictional factor to consider is the orientation of the roof. The optimal condition is that the surface is oriented towards the south, south-west or south-east. Otherwise, however, this does not mean at all that the home is not compliant. The "disadvantage" of a different orientation can in fact be partially rebalanced through an expansion of the surfaces.

Last but not least, pay attention to shading. If there are trees or buildings that create shadows around the house, it is important to observe the evolution of the shadow phases to ensure that the photovoltaic system receives enough sunlight.

Photovoltaic systems on the roof: the weight increases and changes the static conditions of the home. It is therefore advisable in these cases to rely to a technician in the construction sector. In fact, only an expert will be able to protect the building from the risk of significant damage.
