A new report by VDE Renewables, a subsidiary of the VDE Group, that offers quality assurance services for the global renewable energy sector, has demonstrated that SolarEdge’s inverter and Power Optimizer-based PV systems deliver measurable advantages in advanced safety, cybersecurity and higher energy production across a wide range of installation types.
In its in-depth assessment of Module-Level Power Electronics (MLPE) topology and SolarEdge’s approach to PV systems, the report highlights how SolarEdge’s advanced safety features reduce PV system vulnerabilities and exceed international PV safety standards. Reviewed and validated by VDE Renewables, the integration of multiple protective mechanisms, including Sense Connect that proactively identifies and addresses faulty connections long before abnormal temperature is reached. SafeDC™, rapid shutdown, and module-level monitoring was reported to provide a proactive approach to risk mitigation to ensure a significantly higher level of protection for system operators, maintenance personnel, and emergency responders.
The VDE Renewables report also emphasises cybersecurity as a top priority in PV systems, noting that as solar technology becomes increasingly digitised and interconnected, unsecure PV systems also become more vulnerable to cyber threats. With PV systems now integral to energy infrastructure, the consequences of cyberattacks can extend far beyond individual installations, raising wider concerns around grid security and resilience. In this context, VDE Renewables validated SolarEdge’s strong cybersecurity credentials, recognising its comprehensive, built-in defence architecture and highlighting its robust cybersecurity mechanisms that mitigate risks associated with cyber threats. These mechanisms comply with leading international cybersecurity regulations, including IEC 62443, NIST Cybersecurity Framework, and ISO/IEC 27001. Additionally, SolarEdge’s solution includes encrypted communication protocols, secure remote firmware updates, multi-level access control, continuous monitoring, and penetration-tested system architecture.
SolarEdge’s inverter + Power Optimizer solution shown to produce higher energy yields for both simple and complex roofs (4% and 10.5% more power, respectively)
VDE Renewables also validated the performance of SolarEdge’s residential solution against leading traditional string inverter systems, even when using multiple MPPTs. The report confirms results that show a 4% increase in energy production on simple (single facet with no shading) rooftops and an impressive 10.5% increase on complex rooftops. These gains are attributed to SolarEdge’s use of MLPE-based Power Optimizers and advanced Buck and Boost technology. The VDE Renewables report highlights the SolarEdge ONE energy optimisation platform that helps maximise saving potentials with support for both fixed and dynamic electricity tariffs, as well as design advantages such as the ability to use longer strings, enabling lower BoS costs and larger systems within the same roof area – further contributing to overall energy yield.
Arne Gruenewald, Project Manager Batteries and Energy Storage Systems, VDE Renewables: “Our assessment shows that SolarEdge’s technology demonstrates its strategic market position in safety, cybersecurity, and performance – criteria that are essential for the technology’s long-term viability and trust.”
Christian Carraro, General Manager Europe, SolarEdge: “We welcome VDE Renewables’ validation of our technology, being a trusted partner for quality assurance, risk minimisation and certification. As the solar industry grows and evolves, it’s essential that we continue to prioritise not just performance, but also safety and cybersecurity. This report encourages us to keep raising the bar and deliver technologies that support more powerful and secure energy solutions“.
