The importance of correct solar panel placement
28. 8. 2025
The placement of solar panels plays a key role in determining their overall performance and efficiency. Choosing the ideal location for rooftop solar panels ensures that they will be exposed to maximum sunlight, which has a direct impact on the amount of energy they produce. By installing panels in the right location, you can significantly maximise solar energy efficiency and reduce your dependence on traditional energy sources.
One of the key factors affecting panel performance is the availability of sunlight. For optimal results, it is essential to position the panels so that they can absorb sunlight unobstructed throughout the day.
The best results are achieved in locations with minimal shading from trees, buildings or other structures. The orientation and angle of the panels are also important. For example, south-facing roofs are known to capture more sunlight in many parts of the world, making them an excellent choice for homeowners and businesses alike.
The right location can transform solar energy into an efficient and sustainable source of energy and reveal its true potential.
Understanding local weather conditions is equally important. Areas with year-round sunshine naturally produce higher energy output. In less sunny areas, modern technologies such as adjustable mounting systems can help optimise performance.
Key factors to consider when positioning solar panels
Taking these factors into account will help you optimise the location of your solar panels, reduce energy waste and ensure a smooth transition to renewable energy sources. The right assessment today leads to sustainable benefits for many years to come.
The role of solar radiation intensity
The main factor affecting the performance of solar panels is solar radiation. Solar panels work best in locations with continuous sunlight throughout the day. Regions with higher solar radiation intensity and longer hours of sunshine naturally achieve better results.
It is important to avoid placing panels in areas prone to cloudy skies or limited sunlight. Monitoring the average annual solar radiation in your area can help determine the best time and place for installation.
Roof orientation: south-facing roofs vs. others
Roof orientation has a big impact on energy production. In the northern hemisphere, south-facing roofs are ideal because they get even sunlight throughout the day.
East- and west-facing roofs can also work, but they're less efficient than south-facing roofs. Conversely, north-facing roofs are more suitable in the southern hemisphere.
Knowing the orientation of your roof is one of the most important factors to consider when installing solar panels.
Shadow-free areas for maximum efficiency
Shadows from trees, chimneys, buildings or other structures can significantly reduce the efficiency of the panels. Even partial shading can impair the performance of the system by limiting the amount of sunlight absorbed. Perform a shading analysis before installation to identify potential obstacles. If shading problems on roofs persist, ground mounting may be a better option.
The most suitable geographical areas for installing solar panels
Installing solar panels in sunny areas ensures maximum energy production and efficiency. Certain geographical areas, characterised by high levels of solar radiation, are particularly suitable for locations with high solar energy yields. These areas benefit from abundant sunshine, making them ideal for solar energy use.
