Germany is on edge solar panels after revealing the temperature of the cities with plaques on the roof. If what happened to Dubai’s 10 million solar panels caught your attention, you won’t want to miss what comes next. Solar panels have already become an important source of energy, so information about them continues to appear and not all of it is real. Under these circumstances, the European country has shed light on one of the myths circulating about these energy devices.
The transition to more sustainable energy sources has led to a significant increase in energy use solar cells. These devices, which convert sunlight into useful energy, have become a popular alternative for both homes and businesses looking to reduce their carbon footprint and save on energy costs. It should be noted that these “tools” capture the sun’s energy and convert it into electricity or heat.
They consist of multiple solar cells that work via the photovoltaic effect or heat transfer. Its use significantly reduces the ecological footprint and dependence on fossil fuels. Considering the extensive environmental benefits, Germany has put an end to an old myth about solar constructions.
Alert in Germany for the dismantled myth of solar panels
One of the most widespread beliefs about solar panels is that they worsen heat in urban areas, in addition to contributing to global warming with their greenhouse gas emissions. Because it’s dark, the photovoltaic panels They absorb more sunlight than more reflective surfaces. Many assume that solar panels heat the environment during the day.
On the other hand: an investigation into Fraunhofer ISE Institute in Germany has discovered that on average solar panels They can even lower the ambient temperature of cities due to their energy conversion function. Modules in urban environments are usually located on the roofs and roofs of buildings and convert between 20 and 25% of the solar energy they receive into electricity.
During the process, they release less thermal energy to the environment than traditional urban roofing materials. It is worth clarifying that the production of solar panelsLike other industrial processes, it produces carbon dioxide emissions.
The phase of extraction and processing of raw materials, production, assembly, transportation, installation and many other cases are energy-intensive processes. Energy that, depending on the circumstances, comes to a greater or lesser extent from non-renewable sources mix energy of the country where each stage of this supply chain is generated.

However, its levels cannot even be compared to those of coal. The CO2 emitted during the production of solar panels It is a fraction of the emissions that coal-fired power stations produce during their lifetime, the German report warns. The German Federal Environmental Agency (UBA) It records that one kilowatt hour of solar energy produces approximately 40 grams of CO2.
On the other hand, the same amount of energy generated by burning lignite (a type of coal) releases 1,000 grams. In fact, the photovoltaic industry has reduced its carbon footprint by increasing efficiency. Currently, one kWh of solar energy can create only 20 grams of CO2 due to the improved efficiency in its production.
In short, although the generation of solar panels is not 100% CO2-free, its impact is significantly lower than that of fossil fuels and continues to decline partly due to the increasing availability of renewable energy sources in countries such as Chinaa country where wind and solar energy capacity amounts to almost 40% of the total capacity mix energetic. With this information on the table, Germany is on edge solar panels. A milestone that leaves the fury of new solar panels without installation forgotten.
