The efficiency of solar panels in South Africa, as in any location, can vary based on several factors. These factors might include the type of solar panels, their quality, the amount of sunlight received, and the technology used. On average, standard photovoltaic (PV) solar panels typically have an efficiency ranging from 15% to 22%. This means they can convert 15% to 22% of the sunlight that hits them into electricity. The efficiency of our solar panels peak at 20,5%, which is indeed quite decent. We would like to give you an insight into the efficiency of solar panels.
How do we measure solar panel efficiency?
To give you a better insight into the efficiency of solar panels, we are happy to take you back to the place where the solar process starts: the factories. Here, engineers are working every day to design, manufacture and optimise solar panels. After production, the solar panels are tested in laboratories for, among other things, efficiency. Based on historical data and by following strict guidelines, the efficiency of solar panels is guaranteed.
It’s important to note that the efficiency of solar panels tends to decrease with time, and it can be affected by factors such as dust, dirt, shading, and temperature. Regular maintenance and cleaning can help mitigate some of these efficiency losses.
In South Africa, which receives a substantial amount of sunlight, solar panels have the potential to perform very well. However, the actual efficiency you can achieve for your solar panel system depends on various factors:
✓ Location: The amount of sunlight and solar radiation your location receives is a key determinant of solar panel efficiency. South Africa generally has a favorable climate for solar energy.
✓ Quality of Panels: High-quality solar panels tend to have higher efficiency ratings. Investing in better panels can lead to improved performance.
✓ Orientation and Tilt: The angle and orientation of your solar panels also impact their efficiency. Ensuring that they are properly oriented toward the sun can maximize energy production.
✓ Shading: Shading from nearby structures, trees, or other obstructions can significantly reduce efficiency. Minimizing shading is crucial for optimal performance.
✓ Technology Advances: Technological advancements and improvements in solar panel design can result in more efficient panels. Newer, more advanced panels may offer higher efficiency levels.
At Soly, we would be happy to tell you more about the importance of getting the right return from solar panels. Because no matter how you look at it, the return ultimately determines how much money you will make with solar panels.
