Solar panels are a key element of photovoltaic systems, but their efficiency depends not only on quality, but also on proper positioning in relation to sunlight. How to optimally align solar panels using a solar radiation meter?

How to properly position solar panels?
Even the highest quality photovoltaic panels made of aluminum will not be effective if they are not properly installed. There are two key rules that should be taken into account when preparing the space for installation: the angle of inclination of the panels and their orientation.
The optimal angle of inclination of photovoltaic modules is important for maximum efficiency. In Poland, where we are located at latitude, the recommended inclination angle is from 30° to 40°. Getting closer to the equator means a higher angle of inclination.
The best direction to install solar panels in Poland is south. An alternative may be an east-west orientation, however this has a small impact on performance, only about 10-15%.
Roof installation is the most common choice, however, the roof angle must be selected appropriately. If the roof angle is around 30°, installation is easier. Unlike roof installation, an alternative is ground installation, which allows for greater flexibility, but may be hampered by shading and requires underground installations.
How to check the intensity of solar radiation?
Solar radiation meters used by photovoltaic installers are an irreplaceable tool. They allow you to precisely measure radiation in a specific location, which means the solar panels are positioned correctly. With this tool, installers can determine exactly how much solar energy reaches a specific location on a roof or site, which is essential for optimal design and efficient operation of the power grid.
The basic rule is to place the meter in the place where the solar panel is to be mounted. Then turn on the meter and record the readings on the display. The test result will be given in units of W/m². The higher the value, the more intense sunlight. The intensity of solar radiation changes during the day and depending on weather conditions, such as cloud cover or the season. Therefore, it is important to take measurements at different times and weather conditions to obtain comprehensive data in each state. Additionally, the solar radiation meter also allows for the analysis of shading in the installation area, which is important to ensure optimal efficiency of the photovoltaic system.
What should you consider when choosing a solar radiation meter?
When choosing devices, you should pay attention to several important factors, such as measurement precision, comfort of use and safety. Industrial meters available in the Onninen offer meet these criteria, ensuring not only high quality measurements, but also ease of use.
The Fluke FLK-IRR1-SOL 5218288 solar radiation meter is a fantastic solar radiation meter that provides quick and precise measurements of radiation intensity up to 1400 W/m². Equipped with a monocrystalline solar sensor, the device enables continuous monitoring and recording changes in the efficiency of photovoltaic panels, which translates into greater installation efficiency. Even better, you can also control the temperature of both the surroundings and the panels using the built-in sensor or external temperature probe. All this allows you to have full control over the operating environment of your photovoltaic system.
What else? The Fluke IRR1-SOL meter is not just a measurement tool - it is your support when designing, installing, testing and maintaining photovoltaic systems. Thanks to the integrated compass, you can precisely measure the orientation of the roof or terrain, which facilitates installation and adjustment of the installation. And the solid construction, protective cover and clear LCD screen make using the meter simple and convenient, even in difficult conditions.
Now you can perform the key measurements you need to keep your solar system running at peak efficiency using one easy-to-use device. The Fluke IRR1-SOL meter is an indispensable tool for photovoltaic professionals who want to achieve the best results in their work.
Install your solar panel in an optimal way and monitor solar radiation intensity regularly - these are key factors for achieving maximum efficiency of your photovoltaic system. With the Fluke IRR1-SOL solar radiation meter, you will not only achieve great results, but also ensure the long-term efficiency of your installation.
