Did you know that homeowners with solar panels can save £15,000–£25,000 (or ₦5,000,000–₦10,000,000) over 25 years? Yet, many people hesitate to switch to solar because they’re unsure about costs, savings, and the break-even point.
At Choreline.co.uk, we specialize in high-efficiency solar solutions for homes and businesses in Nigeria and the UK. This guide will help you calculate your solar break-even point, maximize long-term savings, and make an informed decision.
Keep reading to discover expert-backed strategies that will help you slash energy bills, boost property value, and achieve energy independence with solar power.

1. Understanding Solar Investment Returns
Switching to solar is a long-term financial decision, not just an eco-friendly choice. To evaluate its worth, you need to assess:
- Initial installation costs
- Annual energy savings
- Government incentives
- Maintenance expenses
- Break-even timeline
Once your solar system pays for itself, every kilowatt-hour generated is pure profit—saving you thousands over time.
2. How to Calculate Your Solar Break-Even Point
Step 1: Assess Installation Costs
Solar system costs vary by size and location:
Location 6kW System Cost (2025)
UK £12,000 – £18,000
Nigeria ₦8,000,000 – ₦12,000,000
Example: A 6kW system in the UK costs £15,000, while in Nigeria, it’s around ₦10,000,000.
Step 2: Factor in Incentives & Rebates
Both Nigeria and the UK offer financial incentives to reduce upfront costs:
- UK: Smart Export Guarantee (SEG) pays for excess energy.
- Nigeria: Some states offer tax breaks or grants for off-grid solar.
Example: A 20% rebate reduces UK costs to £12,000 and Nigeria to ₦8,000,000.
Step 3: Estimate Annual Savings
Solar savings depend on sunlight exposure and local electricity rates:
Location Annual Energy Output Electricity Rate Yearly Savings
UK 7,500 kWh £0.20/kWh £1,500
Nigeria 9,000 kWh ₦70/kWh ₦630,000
Step 4: Compute Break-Even Point
Formula:
Break-Even (Years) = (Net Cost) ÷ (Annual Savings – Maintenance)
Example (UK):
- Net Cost: £12,000
- Annual Savings: £1,500
- Maintenance: £150/year
- Break-Even = £12,000 ÷ (£1,500 - £150) = 8.9 years
Example (Nigeria):
- Net Cost: ₦8,000,000
- Annual Savings: ₦630,000
- Maintenance: ₦75,000/year
- Break-Even = ₦8,000,000 ÷ (₦630,000 - ₦75,000) ≈ 14.4 years
Most Choreline clients break even in 9–15 years, then enjoy decades of free energy!
3. Long-Term Solar Savings: The Real Payoff
Once past the break-even point, your solar system becomes a profit-generating asset. Here’s how:
✔ Dramatic Bill Reductions
- UK homes can cut bills by 80–100%.
- Nigerian households save ₦500,000+ yearly on generator fuel.
✔ Protection Against Rising Energy Costs
- UK electricity prices rise 3–5% yearly—solar locks in low rates.
- Nigeria’s fuel costs fluctuate wildly—solar provides stability.
✔ Increased Property Value
- UK: Solar adds 3–4% to home value.
- Nigeria: Solar-powered homes sell faster in areas with unreliable grids.
✔ Extra Earnings (UK Only)
- SEG payments for surplus energy can earn £100–£300/year.
4. Sample 25-Year Solar Savings
UK Example
- Net Cost: £12,000
- Annual Savings: £1,350 (£1,500 – £150 maintenance)
- Break-Even: 8.9 years
- Years 9–25: £1,350 × 16.1 years = £21,735
- Total Savings: £21,735 + SEG earnings + higher home value
Nigeria Example
- Net Cost: ₦8,000,000
- Annual Savings: ₦555,000 (₦630,000 – ₦75,000 maintenance)
- Break-Even: 14.4 years
- Years 15–25: ₦555,000 × 10.6 years = ₦5,883,000
- Total Savings: ₦5.8M + fuel savings + increased property appeal
If energy prices rise 3% yearly, savings could exceed £25,000 (UK) or ₦7,000,000 (Nigeria) over 25 years!
