Should I Get Solar Panels?
Solar panels are worth it for most UK homeowners with a suitable roof, a 6–8 year time horizon, and reasonable electricity use. But they are not right for everyone. This guide walks you through a 10-point check to decide in about 5 minutes.
Quick Answer
You should get solar panels if you own your home, plan to stay 5+ years, have a south/east/west roof with little shade, spend £80+ a month on electricity, and can pay upfront or finance at a reasonable rate. If you rent, plan to move soon, or have a shaded north-facing roof, consider waiting.
10-point solar panel decision checklist
- 1. Do you own your home? Solar requires planning, installation, and a 25-year panel lifespan — best suited to homeowners. Renters cannot usually install panels, but landlords can. See our rental property guide.
- 2. Do you plan to stay 5+ years? Typical UK payback is 6–8 years. If you are moving within 3, the uplift to home value partially offsets the cost, but you will not fully recover the spend.
- 3. Is your roof south, east, or west facing? South is optimal. East or west still delivers 85–88% of south output. North is usually not worth it. See roof orientation.
- 4. Is the roof free of heavy shade? Morning or afternoon shade from trees, chimneys, or nearby buildings can cut output by 20–40%. Power optimisers help but do not fully fix heavy shade.
- 5. How much electricity do you use? Solar is most worthwhile for households using 2,500+ kWh/year. Low-use households (single occupants, flats) may struggle to justify the upfront cost.
- 6. What is your current electricity bill? If you pay £80+ a month on electricity, solar typically saves 40–60% of that. If your bill is under £50/month, savings are smaller and payback longer.
- 7. Can you pay £6,000–£12,000 upfront? Typical 4kWp with battery costs £8,000–£11,000. Cash pays back fastest; loans at 7%+ may eat into returns. See solar financing.
- 8. Is your roof in good condition? Panels last 25–30 years. If your roof needs replacement within 10 years, do the roof first. Removing and reinstalling panels costs £500–£1,500.
- 9. Do you have space for a battery? A battery (typically 5–10 kWh) takes up a 1m² patch of garage or utility-room wall. Without a battery, savings are 30–40% lower but payback can still be reasonable.
- 10. Are you eligible for any grants? ECO4, Home Upgrade Grant, and Scotland's Home Energy Scotland Loan can cover part or all of the cost for eligible households. See UK solar grants.
✓ Solar is a good fit if…
- You own a house with a south/east/west roof
- Your electricity bill is £80+ a month
- You plan to stay 5+ years
- You can afford £8,000–£11,000 or qualify for finance
- Your roof has minimal shade
- You are at home during the day (raises self-consumption)
- You want to reduce carbon emissions
- You want a hedge against rising energy prices
✗ Solar may not fit if…
- You rent and your landlord is uninterested
- You plan to move within 3 years
- Your only roof is north-facing and heavily shaded
- Your electricity bill is under £50 a month
- Your roof needs replacement within 10 years
- You live in a flat without exclusive roof access
- You need 100% certainty on returns (they depend on energy prices)
Frequently Asked Questions
Should I get solar panels in 2026?
For most UK homeowners with a suitable roof, yes. Panel and battery prices are at their lowest in years, 0% VAT runs until March 2027, and energy prices remain volatile. Payback periods are 6–8 years for most homes.
Are solar panels worth it for a small house?
Sometimes. Small houses often have lower electricity use, so savings are smaller. If your bill is under £50/month, a 2–3kWp system with no battery may still break even over 10 years, but the case is marginal. See our dedicated worth-it guide.
Should I wait for better solar technology?
No. Solar panel technology has plateaued — N-type TOPCon panels offer 22%+ efficiency and will be standard for years. Waiting costs you 12 months of savings (£800–£1,400). The one exception is perovskite panels, which are not commercially ready before 2027–2028.
Should I get a solar battery with my panels?
If you are at home during the day, a battery adds self-consumption and lets you buy cheap overnight grid electricity via time-of-use tariffs. If the upfront cost is tight, you can install panels now and add a battery later — most hybrid inverters support retrofit batteries.
Can I trust solar panel quotes?
Always get 3 quotes from MCS-certified installers. Be sceptical of door-to-door sales, high-pressure tactics, or lifetime "free" solar offers — most of those involve leasing arrangements that don't pay off for you. See our guide on picking an installer.
