Photovoltaics has long been more than just electricity from the roof. For many homeowners, it is a central component of their personal energy transition – an expression of responsibility, independence and sustainability. But what many people don’t know: Existing solar systems can also be significantly optimized with targeted component upgrades – for greater safety, efficiency and sustainability. enwitec GmbH, part of the greenLink Group, offers tailor-made solutions “Made in Germany” for this purpose.
Why an upgrade makes sense
Many PV systems were installed years ago – using the technology of the time. However, the requirements for grid stability, self-consumption optimization and emergency power capability have increased significantly today. At the same time, the technology has evolved. Targeted retrofitting with high-quality components can:
- increase operational safety
- Optimize your own consumption
- Ensure emergency power supply capability
- extend the service life of the system
- Increase the value of the property
