1. Solar Leasing vs. Buying: Key Differences
| Factor | Buying Solar Panels | Leasing Solar Panels |
|---|---|---|
| Ownership | You own the system | Company owns the system |
| Upfront Cost | £5,000–£12,000 | £0 deposit |
| Maintenance | Your responsibility | Covered by leasing company |
| Savings Potential | Higher long-term returns | Lower, but consistent savings |
| Payback Period | 7–12 years | N/A (you don’t own it) |
| Property Value | Increases home value | No impact (may complicate sales) |
2. Cost Comparison Over 25 Years
Scenario: 4kW solar system in South England
(Based on average UK sunlight and energy prices)
| Option | Year 1–10 | Year 11–25 | Total 25-Year Net Savings |
|---|---|---|---|
| Buying (Cash) | -£7,000 (cost) | +£15,000 (savings) | +£8,000–£12,000 |
| Leasing | +£400/year savings | +£400/year savings | +£6,000–£8,000 |
| Solar Loan | -£1,200/year payments | +£900/year savings | +£5,000–£7,000 |
Key Insight:
Buying with cash provides the highest lifetime savings, but leasing offers immediate savings with no upfront cost.
3. Pros and Cons of Leasing Solar Panels
✅ Pros of Leasing
- No upfront cost – Immediate bill reduction without investment
- Maintenance included – Repairs handled by the provider
- Predictable savings – Fixed monthly payments
❌ Cons of Leasing
- No system ownership – You pay forever but never own it
- Lower savings – Leasing companies take a cut of energy profits
- Property sale complications – May require lease transfer
4. Pros and Cons of Buying Solar Panels
✅ Pros of Buying
- Higher long-term savings – After payback, energy is nearly free
- Increases home value – Solar panels boost property prices by ~4–14%
- Eligibility for incentives – SEG payments, 0% VAT
❌ Cons of Buying
- Large upfront cost – Requires significant initial investment
- Maintenance responsibility – You handle repairs (though rare)
5. Solar Loans: A Middle Ground?
Many UK homeowners use solar loans to spread costs while still owning the system.
How It Works:
- Borrow £5,000–£12,000 (secured or unsecured)
- Pay back over 5–15 years
- Savings offset loan payments
Example:
- Loan payment: £100/month
- Energy savings: £80/month
- Net cost: £20/month until loan is paid off
After repayment, you own the system and enjoy full savings.
