5 myths about photovoltaics in Switzerland

Myth 1: Photovoltaic systems are power guzzlers!

Don't photovoltaic systems require more energy in their production than they ever supply? No! After just 1.5 - 2.5 years, your PV system will have paid for itself in energy terms compared to other energy sources such as oil, gas or coal. Although the production of solar panels requires resources and, in particular, energy, photovoltaics scores with a very good environmental balance during its use. This method of energy generation produces zero emissions.2 Ultimately, you can even generate energy with your PV system: Extrapolated over its service life of approx. 30 years, the photovoltaic system produces 15-20 times more energy than was invested in its production

Myth 2: Photovoltaic systems are useless in cloudy weather!

Contrary to common assumptions, modern solar modules can generate energy both on cloudy days and in weak sunlight. This is because the latest solar systems have been designed in such a way that they can also work effectively in scattered radiation, such as in fog or clouds.4 This is made possible by so-called bypass diodes, which divide the PV module into three parts: If one part of the module becomes dirty or covered by shade, the bypass diodes switch off this part and redirect the current.5 This means that your photovoltaic system still produces 10 - 25% of its normal output, even on cloudy days or days with little sunshine.

Myth 3: Photovoltaics is too expensive!

Is the cost still holding you back from deciding on a photovoltaic system? While this would have been a decisive argument years ago, the cost of solar modules has fallen sharply in recent years. In addition, there are one-off payments in Switzerland that cover 15-25% of the investment costs, depending on the size of the system. There are also additional, individual subsidies from some cantons and municipalities that guarantee further financial support. And the larger you plan your system, the cheaper the kilowatt hour (kWh) of electricity will be in the end. Good to know: When purchasing a photovoltaic system, tax deductions of up to 30% of the investment costs are possible, depending on where you live.6 It pays off twice over to find out in advance!7 Thanks to a photovoltaic system, you will be less dependent on rising electricity prices and actively contribute to climate protection. 

4th Myth: Photovoltaic systems are harmful to the environment! 

Glass, silicon, aluminum and some plastic are the main components of standard panels - plus some copper, very little lead and silver. Currently, around 95% of these ingredients can be recycled. In addition, an advance recycling fee is charged. However, new processes are being worked on at full speed to increase the proportion of recyclable components. If you are still wondering about the composition: Other technologies for electricity production also contain problematic substances and also have their downsides.8 However, if you consider the long service life and low-emission use of your PV system, you will see that this technology has a good eco-balance and thus makes a significant contribution to environmental protection.

5. myth: Photovoltaic systems are high-maintenance

Does the belief in intensive maintenance still keep you away from your PV system? Regular inspections are recommended to keep photovoltaic systems in an operational, proper and safe condition and to delay their wear and tear. However, there is no statutory maintenance obligation for photovoltaic systems and, in principle, no technical necessity. Accordingly, there is also no specific time interval within which maintenance must be carried out. However, according to the motto "Trust is good, control is better", it is advisable to carry out a visual inspection of your system after a storm, for example. It is also advisable to carry out regular cleaning or removal of vegetation at locations with high dust emissions, changes in shade or vegetation. This is the only way to maximize the performance of the photovoltaic system.9
Unaffordable, expensive, harmful to the environment, time-consuming and inefficient - quite the opposite! As we have shown you, many of the common myths and misunderstandings about photovoltaic systems are based on incomplete or outdated information. Especially in times of advancing climate change, photovoltaics represent an important solution for a more sustainable lifestyle.
