The ongoing Iran war has led to a significant increase in demand for rooftop solar systems across Europe as households strive to reduce their energy costs amid soaring prices. Interviews with energy equipment wholesalers and renewable utilities in Germany, Britain, and the Netherlands reveal that demand has more than doubled since the conflict began in late February. Notably, Solarhandel24, a German solar equipment wholesaler, reported net sales tripling in March to nearly €70 million (approximately $82 million), with expectations to triple again in April. Similarly, Germany's Enpal saw a 30% rise in orders year-on-year, driven by increased installations of rooftop solar systems. This shift towards solar energy is seen as a crucial step in enhancing European energy resilience, as highlighted by industry leaders. The demand for energy storage technologies is also on the rise, with increases of 40%-50% reported. Additionally, upcoming changes to Germany's renewable energy law are anticipated to further stimulate the market for rooftop installations, which typically cost between €10,000 and €20,000 for an average family home. The overall surge in demand underscores the growing recognition of the need for energy independence in Europe.
