Why an Upgrade Makes Sense

Many PV systems were installed years ago – using the technology available at the time. But today, the demands on grid stability, self-consumption optimization, and backup power capability have increased significantly. At the same time, technology has advanced. Targeted retrofitting with high-quality components can:

• Increase operational safety
• Optimize self-consumption
• Ensure backup power capability
• Extend the system’s lifespan
• Increase property value
