Myths about solar energy: what is really true?
Solar energy is one of the most important pillars of the energy transition. It offers a clean and sustainable alternative to fossil fuels. Nevertheless, there are many myths and misunderstandings that could unsettle potential users. In this article, we shed light on the most common myths about solar energy and explain what is actually behind them.
Myth 1: Solar energy only works with sun and heat
Truth: Solar energy is not generated by heat, but by sunlight. Photovoltaic systems also work on cloudy days as they can utilise diffuse light. In fact, solar panels often work more efficiently in cooler weather, as high temperatures can affect performance.
Myth 2: Solar systems are too expensive
Truth: While the purchase costs for solar systems used to be high, they have fallen significantly in recent years. In addition, many countries offer subsidy programmes, low-interest loans and tax breaks that make the investment more affordable. In the long term, solar energy significantly reduces electricity costs and often pays for itself within a few years.
Myth 3: Solar modules are not sustainable
Truth: The production of solar modules requires energy and raw materials, but the CO₂ emissions are quickly offset during operation. Modern solar modules have a lifespan of over 25 years and many manufacturers are implementing recycling programmes to further reduce their environmental impact.
Myth 4: Solar energy cannot supply constant electricity
Truth: It's true that solar energy is weather-dependent, but modern energy storage solutions make it possible to store surplus electricity that can be used when needed. In addition, solar energy is often combined with other renewable energies to ensure a stable supply.
Myth 5: Solar systems are difficult to maintain
Truth: Solar systems require little maintenance. Regular cleaning and occasional checks of the electrical components are enough to ensure optimum performance. Many manufacturers offer warranties and maintenance services.
Myth 6: Solar systems are only worthwhile for homeowners
Truth: Tenants can also benefit from solar energy. Concepts such as tenant electricity models or communal systems make it possible to use renewable energy without having to own a system yourself. There are also portable solar modules for balconies or gardens that can be used flexibly.
Myth 7: Solar energy is inefficient
Truth: Modern solar modules have efficiencies of up to 25 % and are therefore much more efficient than previous generations. In addition, scientists are constantly developing new technologies, such as tandem cells, which promise even higher efficiencies.
Conclusion: Facts instead of myths
Solar energy is a reliable, sustainable and affordable energy source that can make a major contribution to the energy transition. Many of the widespread myths are based on outdated information or misunderstandings. With today's advances in technology and infrastructure, going solar is easier and makes more sense than ever before.
