7. Solar Panels and Home Energy Systems
Green energy is becoming more accessible, and that means cheaper installation for solar panels and battery systems in 2025. The Inflation Reduction Act in the U.S. continues to offer generous tax credits, while global production capacity for solar components has reached record highs. That means more supply, lower costs, and better financing options for homeowners. The International Energy Agency projects a 15–20% drop in the average cost of solar panel systems by the end of 2025. Add in government rebates and local energy buyback programs, and going solar could finally be within reach for many middle-class households.
