Rooftop solar can provide five hours of 'free' air conditioning a day. But is it green?

Rooftop solar panels are increasingly being used to power air conditioning systems, offering up to five hours of "free" cooling each day during peak sunlight hours. While this combination of technologies is seen as a way to reduce energy costs and carbon emissions, some analysts question whether it’s genuinely sustainable, especially if it leads to over-reliance on air conditioning in an already energy-intensive continent. This raises important questions about balancing technological innovation with environmental responsibility, especially as Europe grapples with rising temperatures and energy demands.
