Although the net-metering scheme will be abolished, installing solar panels remains a good investment. Especially if you can charge your electric car at home, after all, public charging has become increasingly expensive. And also for homeowners with a heat pump, solar panels are actually a must. But did you know that with the right roofing material, you can get even more out of your solar panels and further reduce the payback period? In this blog, we talk more about the importance of proper roofing before installing solar panels.
Because of the great benefits of solar panels, as a proud owner you often want to install them sooner rather than later. But if you rush the process, you can run into significant problems. A successful installation process therefore begins with inspecting the roof on which the solar panels will be installed. It is common for roofing materials to turn out to be severely outdated and leak. If you are doing something sustainable by purchasing solar panels, you would do well to replace your roofing at the same time.
Most roofs in the Netherlands have a black top layer. The increasing focus on sustainability does mean that white roofing is increasingly replacing it. The main effect of white roofing is that the temperature of the roof remains lower. As a result, the space under the white roof also stays a lot cooler and you use much less energy to keep the temperature inside at a comfortable level.
But the biggest advantage of white roofing is in optimizing the output from your solar panels. This is because solar panels work best when the roof temperature is around 25°C. Each additional degree produces on average about 0.5% less energy. When you consider that the temperature on roofs with a black top layer can be as high as 80°C, it is clear that this results in a lot of yield loss. With white roofing, the temperature of the roof remains manageable and technical installations on the roof, such as the outdoor units of air conditioners and heat pumps, last longer. Moreover, the reflection of sunlight is also partly absorbed again by the solar panels. The result is an above-average return from your solar panels. In the long run, this means significant savings on your energy bill and a significant reduction in the payback period of your panels.
