✅ The Pros

  • Significant Bill Reductions

    Slash electricity bills by 50-80% depending on system size and habits.

  • 0% VAT Incentive

    Government tax relief makes it 20% cheaper than historical norms until 2027.

  • Low Maintenance

    No moving parts. Rain cleans them mostly. 25-year warranties are standard.

  • Energy Independence

    Protect yourself against volatile global gas prices and price cap hikes.

  • Property Value

    Energy efficient homes (EPC A or B) are increasingly desirable to buyers.

❌ The Cons

  • High Upfront Cost

    £6,000+ is a lot of money to find, though financing is available.

  • Weather Dependent

    Generation drops by ~90% in December compared to June. You will still need the grid in winter.

  • Can't Take It With You

    Unlike a car, you can't easily move it. You need to stay in your home 5-10 years to see ROI.

  • Aesthetics

    Some people dislike the look of panels, though sleek all-black options are now standard.

  • Inverter Replacement

    While panels last 25 years, the inverter usually fails after 10-12 years and costs £800-£1500 to replace.

The Verdict?

For most homeowners with a south/east/west facing roof who plan to stay put for 5+ years, the pros heavily outweigh the cons. The financial return (8-10%) beats most savings accounts.
