Introduction: from optional to essential<\/strong><\/h2>\n\n\n\n

Across the world, the energy landscape is changing faster than ever. In 2025 alone, the EU added more than 60 GW of new solar capacity<\/strong>, pushing solar to become one of the dominant electricity sources. But there\u2019s a problem: solar energy is intermittent<\/strong>. Production peaks during the day, while demand rises in the evening.<\/p>\n\n\n\n

This is where solar batteries step in.<\/p>\n\n\n\n

In 2026, solar batteries are no longer a luxury add-on. They are becoming a core component of energy systems<\/strong> in both residential and tertiary buildings. Rising electricity prices , grid constraints, and the push for self-consumption are accelerating adoption.<\/p>\n\n\n\n

At PlanItPower, we see solar batteries not just as storage devices\u2014but as smart energy enablers<\/strong> that empower buildings to produce, store, and intelligently manage their own energy.<\/p>\n\n\n\n
