Optimal solar panel installation angle
The solar station is designed as a well-functioning system, for which all design characteristics are important, as well as following the technology of assembly and connection of photomodules. One of the key parameters is the angle of installation of solar panels. The correctness of the calculation directly affects not only the efficiency of the solar power plant, but also its service life.
The angle of installation of solar panels - design features of profitable technological solar power plants
The calculation of the angle of inclination of solar panels is one of the mandatory components of the range of services offered by Sunsay Energy specialists. The impact of this indicator cannot be underestimated for a number of reasons:
- Effective operation of photomodules is possible only with maximum absorption of solar energy by their surface.
- The angle of incidence of the sun's rays is a variable, which is affected by geographic location, season, time of day.
Proper installation of PV modules is the result of an integrated professional approach
It is extremely rare that the angle of inclination of the roof for solar panels in Kyiv corresponds to the recommended values. But each customer a priori expects to receive the most efficient system of alternative energy supply. To implement this condition, Sunsay Energy specialists take into account three important points:
- The optimal angle of inclination is obtained, focusing on the geographical latitude of the region and seasonal changes in the angle of incidence of the solar flux.
- Properly mounted photomodules should not be shaded by trees, buildings as the Sun moves across the sky.
- The maximum generation of energy flow from the solar power plant occurs when the rays fall on the panel at a right angle.
- Be sure to take into account possible changes in the position of photomodules in case of worsening weather conditions - strong gusts of wind, heavy snowfalls in the cold season.
In order to maintain the productivity of stations in such conditions, special attention is paid to increasing the reliability of attaching panels to roof elements or other fixed structures.
The maximum performance of PV modules on the territory of Ukraine is ensured when they are installed on a pitched roof oriented to the south at an angle of 27-35 degrees relative to the ground level. Real conditions rarely meet ideal criteria. Therefore, any project for Sunsay Energy specialists begins with a thorough study of the object to select the best option for the supporting structure with the correct calculation, taking into account the angle of inclination of the solar panels.
The key to correct placement of PV modules is 3D modeling based on real data
The development of the project of the future solar power plant is carried out on the basis of aerial photography processed with the help of special programs, made with the help of drones. An innovative approach to data collection allows you to get the most accurate roof layout, evaluate not only its appearance and design features, but also orientation relative to the cardinal points, the presence of shading.
Even with a complex roof configuration, it is possible to determine the angle of inclination of the roof for solar panels in each area. Based on the collected data, a project of a supporting structure is being developed that ensures the optimal location of solar panels for the efficient operation of a home solar power plant.
Solar power plant installation on a flat roof
When calculating the angle of inclination of solar panels for a horizontal roof, the frame for photomodules is designed in the form of a system of triangles. Thus, all elements that accumulate solar energy are located at an optimal angle to the light flux. By maintaining a distance of 1-1.5 meters between the rows, it is possible to eliminate the shading of the panels, guaranteeing the high efficiency of the solar power plant.
Installation of panels on a shed roof
Different options are possible here depending on the initial angle of inclination of the roof. If the slope is small (up to 15 degrees), the installation angle of solar panels within 27-35 degrees is provided using a special inclined design. The panels on such a support are located in close proximity to each other.
The metal frame significantly increases the cost of the project. In order to avoid unjustified costs, Sunsay Energy specialists calculate in advance the indicators of the future SPP, evaluating the feasibility of adjusting the existing roof slope.
If the panels are installed on a gable roof
For such roofs, when choosing a side for mounting solar panels, the south orientation rule applies. Subject to this condition, further work, including the calculation of the angle of installation of solar panels, is carried out similarly to shed roofs, starting from the initial slope of the structure.
If the roof is oriented to the west or east, the installation angle of the solar panels must exceed 35 degrees to ensure efficient operation of the station. This feature is taken into account when designing the base for photomodules.
Design solutions for a multi-pitched roof structure
In such situations, the calculation of the angle of inclination for solar panels is carried out in each individual section, achieving high SPP generation rates. In order to optimize operation, leveling the influence of shading, the system is equipped with special inverters with optimizers to ensure independent operation of PV modules.
Sunsay Energy specialists offer options for installing solar panels, based on the characteristics of the area and the financial capabilities of the customer. Many years of experience, high-quality after-sales service allow us to guarantee the achievement of optimal performance of the solar power plant, to eliminate errors and serious errors in the functioning of the system.
