Cost Analysis
Residential solar costs EUR 800-1,400 per kWp installed. Commercial installations benefit from scale at EUR 600-1,000 per kWp. With current electricity prices, residential payback is 5-8 years, commercial 3-5 years.
Technology Trends
TOPCon cells are becoming the new standard, offering 22-24% efficiency. Bifacial panels gain ground with 10-30% additional yield. Battery storage costs have dropped 40% since 2022, making self-consumption increasingly viable.
