Balcony Power Plants: Safety Concerns Highlighted

Stiftung Warentest evaluated eight balcony power plant models, revealing significant safety concerns. Only two products earned a 'good' rating, while five were deemed 'poor' due to weak mounting brackets.

These brackets, prone to bending or breaking in strong winds, pose a risk of damaging solar panels. Despite these issues, balcony power plants offer potential benefits.

Under optimal conditions, they can produce up to a megawatt-hour of solar energy annually. This output can lead to cost recovery in less than two years, especially with government incentives.

The price for these systems varies, with the most effective unit costing 515 euros. Even the least expensive option, priced at 329 euros, showed promise.

However, the system's efficiency largely depends on installation angle and solar exposure. As the demand for sustainable energy grows, ensuring the reliability and safety of these systems remains crucial.
