This Home Doesn’t Just Avoid Energy Bills — It Ends the Year £196 in Credit.
In Little Lever, BL3 (Bolton), this wasn’t simply a solar install.
It was a full structural and energy upgrade.
And the result?
- £1,865 annual electricity bill eliminated
- £2,061 total annual saving
- £196 net credit position
- 7 years 10 months payback
That’s not marginal improvement.
That’s structural change.
Solar & Re-Roof Project in BL3 Little Lever – Aiko + Hanchu System with 7 Year 10 Month Payback
This project combined:
- Full re-roof
- 8.84kW solar PV system
- Hanchu hybrid inverter
- Hanchu battery storage
- Tank & cylinder upgrade
- Solar iBoost integration
Instead of replacing the roof and continuing to pay energy bills, the homeowner turned the roof into a producing asset.
Financial Snapshot – What the Numbers Actually Show
From the year-one system model:
- Total Solar Generation: 7,335 kWh
- Electricity Imported After Installation: 4,745 kWh
- Electricity Exported: 4,873 kWh
- Export Credit Earned: £732
- Annual Utility Bill Before: £1,865
- Annual Utility Bill After: -£196
- Total Annual Savings: £2,061
This home now:
- Generates more electricity than it needs in key months
- Exports surplus back to the grid
- Ends the year in a positive financial position
The Hardware – Built for Performance
Aiko 465W Solar Panels
We installed 19 × Aiko 465W panels, delivering an 8.84kW system.
Aiko panels were chosen for:
- High efficiency per panel
- Strong low-light performance (critical in Greater Manchester conditions)
- Long-term degradation stability
- Clean, symmetrical roof layout
High-output panels mean stronger generation and faster battery charging.
Hanchu Hybrid Inverter & Battery System
This project uses a Hanchu hybrid inverter paired with Hanchu battery storage.
Why Hanchu?
- Reliable hybrid integration
- Strong charge/discharge performance
- Efficient export management
- Stable long-term cycling
Battery storage is what converts solar generation into real financial performance.
Without storage, you reduce bills.
With storage, you restructure them.
Solar iBoost – Turning Surplus into Hot Water
Instead of exporting all surplus electricity at a lower rate, the system includes a solar iBoost to divert excess solar into water heating.
That means:
- Reduced gas consumption
- Increased total system efficiency
- Higher self-consumption
- More value retained within the home
Month-by-Month – Where the Bill Turns Negative
Here’s what that looks like across the year:
| Month | Bill Before (£) | Bill After (£) |
|---|---|---|
| Jan | 186 | 58 |
| Feb | 180 | 40 |
| Mar | 181 | 4 |
| Apr | 155 | -52 |
| May | 140 | -98 |
| Jun | 134 | -93 |
| Jul | 130 | -90 |
| Aug | 128 | -75 |
| Sep | 139 | -31 |
| Oct | 154 | 15 |
| Nov | 173 | 46 |
| Dec | 185 | 60 |
From April through September, the system produces surplus.
Negative figures mean credit.
That’s engineered energy independence.
Tank & Cylinder Upgrade – Improving Pressure & Heating Efficiency
This wasn’t just solar.
The homeowner upgraded their hot water tank and cylinder as part of the eco project.
The result:
- Improved hot water pressure
- More consistent flow
- Increased heating efficiency
- Better thermal retention
- Lower overall system losses
Energy efficiency is cumulative.
Every upgrade compounds savings.
7 Years 10 Months Payback – Then Pure Return
Most roof replacements don’t pay you back.
This one does.
With a projected 7 years 10 months payback, the system transitions from cost to asset.
After payback:
- The roof continues generating savings
- Export credit continues
- Energy inflation risk is reduced
- Household operating costs stabilise
This is long-term financial infrastructure.
A Full Eco Upgrade – Fit for Future Generations
This BL3 property is now:
- Structurally renewed
- Energy efficient
- Lower carbon
- Lower cost to operate
- Future-ready for EV integration
- Protected from long-term energy volatility
It’s no longer just a house.
It’s a producing asset.
Why Homeowners in BL3 Are Acting Now
Across Little Lever and Bolton:
- Older roofs need replacing
- Energy prices remain volatile
- Export tariffs reward surplus generation
- Smart battery systems amplify returns
The difference between a standard roof replacement and an eco-upgrade?
Intentional design.
