The orientation of the solar panels is one of the most important factors to take into account when installing a photovoltaic installation . In this article, we help you understand how to get the most out of your installation depending on its orientation and inclination. Orientation Inclination Shades Orientation First, let's talk about the orientation of your solar installation. Since we are in the northern hemisphere, the orientation in which we will receive the most sunlight is south. There are two options for installing solar panels. The first is on the roof itself, taking advantage of the inclination of the roof and the optimal slopes. The second is on a flat roof , for which forced inclination structures are used.
Use our solar self-consumption calculator to find out how much you can save by installing solar panels on the roof of your house What happens if your roof does not face south? Asier San Sebastián, Head of Installations and Works at Lumio , explains it to us using the following graph: “Here is the production Chinese Student Phone Number List graph for a facility facing only south (blue line) and another facility facing east-west (orange line) for one day: What is the best orientation to install solar panels? Lumio Although the south-facing installation (blue line) reaches a higher maximum power, the east and west-facing installation (orange line) reaches higher power for a greater number of hours per day. Therefore, the two types of orientation are profitable in different ways.” Inclination The inclination of the photovoltaic installation is given by latitude. The rays that hit the equator are practically perpendicular. As you move away from the equator, and due to the fact that the earth is round, the rays hit the earth at a smaller angle.
Thus, the further we are from the equator, the greater the inclination of the panels will be to take advantage of the incidence of the sun's rays, and this so that the sun's rays hit the panels perpendicularly. In Spain, the ideal inclination of photovoltaic modules is between 20 and 40 degrees . Shades Another essential point when installing photovoltaic modules is to carry out a good analysis of the roof to detect elements that could generate shadows and thus reduce the performance of the installation. These elements are usually chimneys, height differences between roofs, trees or large surrounding buildings. In this situation, there are two alternatives: the first is to avoid (as far as possible) elements that will cast shadows on the installation. If this is not possible, another alternative is to install power optimizers on each panel to customize the output of each panel and thus obtain superior performance.
