One of the important factors to consider when installing solar panels is shading calculations. Shading is important to understand how shadows falling on the panels affect efficiency.
Causes and Effects of Shading
Shading can be caused by different factors. These include
Buildings: Nearby buildings and structures can cause shadows to fall on solar panels.
Trees: Large trees or plants can block the panels’ access to sunlight.
Relief: The slope of the land, mountains or high surfaces can cause solar panels to be shaded during some hours.
Depending on the amount of shade that falls on the solar panels, shading can reduce the production efficiency or prevent the panel from fully operating. This can reduce the total production potential of solar sites.
Solar Road Works
It is necessary to examine the location where the solar panels will be installed and to carry out solar path studies. These processes help to determine how long the sun can directly reach the panels throughout the year. Understanding the path of the sun at different times of the day and seasons allows the panels to be placed in the most efficient way.
Shadow Analysis
Shadow analysis involves detecting the shadows falling on the panels. Potential sources of shade, trees, buildings, chimneys, etc., should be identified in the area where the building or power plant will be installed. Particular attention should be paid to the possibility of shading in the morning and afternoon hours, since solar panels produce the most during these hours.
Shading Analysis Tools
You can use different tools and software for shading analysis. For example, professional solar panel design software such as MapperX helps you perform shading analysis. MapperX provides detailed shading analysis for the location and panels you specify.
Shading Maps and Efficiency Calculations
Shading maps are created using the data obtained as a result of shading analysis. These maps show which panels will be shaded, when and for how long. Using this information, you can ensure the most efficient placement of panels. You can also calculate the potential production loss of the panels as a result of shading analysis.
Panel Placement and Monitoring Systems
After determining the best location of the panels based on the shading analysis, the placement of the panels can be started. Using tracking systems, the panels should be placed at the best angle to the sun. Tracking systems enable solar panels to follow the sun throughout the day and generate more energy.
Shading calculations are one of the most important stages of solar panel installation. By performing accurate shading analysis, you can ensure the best placement of the panels and achieve maximum energy efficiency. Since every shadow element can have a negative impact on energy production, it is important to perform meticulous calculations.
