Solar panels are inaccessible, solar panels only work when the sun is shining, photovoltaics cannot make us energetically independent: these and other beliefs, even if they had a grain of truth in the past, are now real myths to be debunked . Research continues and today photovoltaics (and all renewables) are not the future, they are and must be the present.
Here are some myths to dispel, some of the hardest to die.
Solar panels only work when the sun is shining
Many people think that solar panels only produce energy when there is full sun, but this is not true. Modern photovoltaic technology is able to capture and transform even energy into energy diffused lighti.e. the one present on cloudy or overcast days.
The latest generation solar cells are designed to optimize the absorption of light at different intensities and angles, improving performance even in low light conditions. For example, systems with optimizers can maximize energy production on each individual module, even if part of the roof is in the shade. Therefore, even on gray days, a photovoltaic system is able to generate useful energy for the home.
Solar energy is ineffective in the winter months
Winter is often thought to represent a “dead” period for solar energy production. In reality, even in the coldest months, photovoltaic panels continue to work. Indeed, low temperatures can increase the efficiency of photovoltaic cellsas these work best in conditions that are not excessively hot. The important thing is that there is light, even if diffused, and that the system is well designed to capture the greatest amount of energy possible. Thanks to storage systems, the energy produced during the day is stored and used in the evening hours, when consumption tends to increase. Therefore, winter is not an obstacle for those who choose to adopt a modern photovoltaic system.
Storage batteries discharge quickly and do not last over time
Another misconception is that storage batteries are not efficient and degrade quickly. In fact, the modern ones lithium batteries used in residential storage systems have very long life cycles, often guaranteed up to 15 years or older. Advanced technologies also make it possible to optimize stored energy and consumption, ensuring that stored energy is used intelligently. Furthermore, thanks to smart management systems, the battery adapts to the family’s daily needs, optimizing loads and reducing waste. This ensures not only a longer service life, but also a 40% higher energy efficiency compared to older systems.
Installing photovoltaic systems and batteries is complicated and time-consuming
The perception of long and complicated installations is now outdated, the most recent photovoltaic systems and storage batteries are designed for an installation quick and simplified. Thanks to pre-assembled solutions and a modular design, installation times are short reduced by up to half compared to the past.
Furthermore, the presence of systems without internal wiring and with optimized connections facilitates the work of technicians, who can complete the installation in a few hours. Expanding the system is also simple: if a family wants to increase the storage capacity, they can do so easily by adding new compatible modules.
Storage systems are not safe
Safety is a top priority in modern storage systems, the most advanced batteries integrate multi-level protectionwhich covers electrical, structural and environmental aspects. This means they are designed to withstand extreme conditions such as temperatures between -20°C and +55°C and can withstand immersion, shock or very high pressure tests. For example, some batteries are certified to withstand pressures up to 5 tonsmaking them safe even in garages or garages where they could suffer accidental collisions. Furthermore, advanced monitoring and active protection systems guarantee that any anomaly is detected and managed immediately, avoiding risks for the family.
Solar panels are ugly
The appearance of photovoltaic panels may once have been an obstacle, but today modern designs are elegant and minimalist. The new generation panels integrate perfectly with the architecture of the house, thanks to clean lines and neutral colors that do not compromise aesthetics. Storage batteries also follow the same philosophy: with design compact and without framesare designed to be positioned discreetly, both inside and outside the home. Furthermore, the functional aesthetics of some products, such as side grills for cooling, combine beauty and technical performance, offering solutions that adapt to any domestic context.
Photovoltaic and all renewables are the only way out of the energy and climate crisis.
Maintenance of photovoltaic systems and batteries is expensive and complicated
Another common myth is that photovoltaic and storage systems require expensive and frequent maintenance. In fact, both the panels and the batteries are designed to be reliable and long lasting. Photovoltaic panels, for example, simply require occasional cleaning to remove dust or debris that could reduce efficiency. Modern batteries are equipped with intelligent monitoring systemswhich automatically report any anomalies and help maintain energy efficiency. With guarantees that can exceed 15 yearscurrent systems offer not only a very long life cycle but also maintenance costs reduced to a minimumthus guaranteeing an excellent return on investment.
