Do solar savings increase over time?

Solar savings increase over time because electricity prices historically rise 5-7% per year. A 4kW system saving £580 in year 1 (at 24.5p/kWh) would save £750 in year 10 (if prices rise 3%/year) and £1,150 in year 25. This compounding effect means the MAJORITY of your lifetime savings come in the later years — after payback. Solar is one of the few investments where the return accelerates over time rather than declining.
