Choosing the right location in which to install the photovoltaic panels is one of the most important issues of the entire investment.
It is also the choice of site that determines the effective operation of the entire installation, as well as the subsequent logistics of its maintenance and servicing methods.
The most common choices are the roofs of buildings or unused land.
So what is key when choosing a site for a photovoltaic installation?
The most important factor that determines where we should install photovoltaic panels is the degree of sunshine for the site. Particular attention should be paid to elements such as, the angle of the sun's rays.
In addition, it is advisable to avoid shading of the site in question, as well as how long the sun operates in a given location during the day.
Consideration should also be given to factors such as the weather conditions that prevail at the site where the photovoltaic panels are to be installed .
Before installing a photovoltaic installation, it is worth checking ...the wind - its direction and also its strength. An important factor worth considering when choosing a location for a photovoltaic installation is the area of snow accumulation on a particular part of the roof.
The most common choice for the location of photovoltaics is on the roofs of buildings. The best roofs are those where there are no other objects, poles, chimneys or trees around to shade the photovoltaic site.
When installing panels on roofs, it is important to ensure that the panels are cooled by a constant flow of air.
The pitch of the roof is also an important factor.
Photovoltaic panels show the greatest efficiency on roofs with an inclination of 25 - 36 degrees.The panels will also work well on flat roofs. It is important that they are positioned in the direction in which the sun is strongest.
Another option is unused land. With this solution, we can install more panels. This is how photovoltaic farms are created.
