3 ways to improve photovoltaic safety according to SolarEdge

Photovoltaic systems, while generally safe, vary in their safety features. Understanding the basics of how these systems work is crucial. A photovoltaic system includes solar modules and an inverter; modules convert solar radiation into DC, which the inverter changes to AC for home and business use. SolarEdge systems stand out for their safety features: SafeDC™ reduces voltage to 1V when the inverter is off, preventing risks during maintenance or emergencies. They also include built-in arc detection to prevent fire hazards and offer a monitoring platform for enhanced performance visibility. VOLTMAX SARL relies on SolarEdge for optimal safety and efficiency. Visit www.voltmax.lu for more information. Read the entry

Do photovoltaic panels produce a magnetic field?

Solar panels, subject to debate for their health effects and environmental impact, raise concerns about generating a magnetic field. While they do emit a magnetic field, research suggests it poses no significant health risk. Additionally, materials like roofing and insulation can reduce this field, with the World Health Organization confirming no negative impact on health. Furthermore, solar energy from photovoltaic panels helps reduce emissions, supporting an overall improvement in societal well-being. Read the entry

Recover and reuse: Recycling of photovoltaic panels

Recycling of photovoltaic panels in Europe and Luxembourg is gaining increasing importance in the context of the growing demand for sustainable energy solutions. This process, which enables the recovery of valuable materials and reduces environmental impact, becomes not only an answer to ecological needs but also to legal requirements imposed by EU directives.
