Solar Panels vs ISA

Is solar a better investment than an ISA?

Solar panels vs ISA — investment comparison: CASH ISA: 4-5% return (2026). Tax-free. Zero risk. But: inflation erodes real returns (real return: 1-2%). STOCKS & SHARES ISA: 7-10% average annual return. Tax-free. Moderate risk. Volatile. SOLAR PANELS: 8-15% annual return (energy savings ÷ installation cost). Tax-free. Returns INCREASE with inflation (electricity prices rise). Near-zero risk (panels are proven technology). Tangible asset (increases property value). EXAMPLE: £8,000 invested in solar: saves £800-£1,200/yr = 10-15% return. £8,000 in Cash ISA: earns £320-£400/yr = 4-5% return. £8,000 in S&S ISA: earns £560-£800/yr = 7-10% (with volatility risk). SOLAR WINS for homeowners with suitable roofs. It's the only investment that: provides tax-free returns, beats inflation automatically, adds property value, AND reduces carbon emissions.
