7.6kW AIKO Solar Panel & Sigenergy Battery Installation in Orrell WN5
Solar and Battery Installation Orrell: £1,394 Estimated Annual Savings with Sigenergy
Every home uses energy differently. Because of this, the most effective solar systems are designed around the property’s energy needs, rather than simply filling the available roof space.
This Solar and Battery Installation Orrell project on Sherborne Road, Orrell (WN5), shows how AIKO solar panels and Sigenergy battery storage can help a homeowner generate renewable electricity, reduce grid reliance and lower long-term energy costs.
Installed by NRG Solar Ltd, the system combines 16 AIKO 475W solar panels, a 6kW Sigenergy inverter and 18.08kWh of battery storage.
The system is expected to provide approximately £1,394 in annual energy bill savings, with an estimated payback period of 11 years and 11 months.
System Overview
This Orrell solar installation has been designed to generate electricity throughout the year while allowing the homeowner to store and export surplus energy.
System Specifications:
- 16 × AIKO 475W solar panels
- 7.6kWp solar PV system
- 6kW Sigenergy inverter
- 18.08kWh Sigenergy battery storage
- 2 × SigenStor BAT 10.0 batteries
The AIKO solar panels generate electricity during daylight hours. The Sigenergy battery then stores surplus energy for use later.
As a result, the homeowner can use more of the electricity generated by the system and reduce their reliance on the grid.
How This Solar and Battery Installation in Orrell Works
During the day, the solar panels generate renewable electricity from sunlight.
The home uses this electricity first. Any surplus power can then charge the battery storage system.
Later, when solar generation falls, stored energy can be used to help power the property. This reduces the need to buy electricity from the grid.
For this installation, the expected energy split is:
- 27% self-consumption
- 73% exported to the grid
The high export level means the system is expected to produce a significant amount of surplus electricity. The homeowner can therefore benefit from Smart Export Guarantee payments for exported energy.
Solar Generation in Orrell:
Solar generation changes throughout the year. This system is expected to produce its highest output between April and August.
The strongest month is expected to be May, with average daily generation reaching approximately 28kWh.
June follows with around 23.9kWh generated per day.
During periods of strong generation, the solar panels can produce more electricity than the home needs. The battery can store some of this surplus, while additional energy can be exported to the grid.
Financial Results
This system has been designed to deliver long-term financial benefits through a combination of energy savings and electricity exports.
Estimated Annual Energy Bill Savings:
Approximately £1,394
Estimated Payback Period:
11 years and 11 months
Estimated Annual Energy Bill After Installation:
Approximately -£276
A negative annual energy bill indicates that the system is expected to generate more financial value than the property’s remaining annual electricity costs under the stated assumptions.
The homeowner can also benefit from income generated by exporting surplus electricity through the Smart Export Guarantee.
Estimated Cumulative Bill Savings
The projected financial return continues to grow as the system generates renewable electricity and exports surplus energy.
| Year | Usage Savings | Smart Export Guarantee | Total Savings |
|---|---|---|---|
| 1 | £611 | £608 | £1,219 |
| 5 | £3,585 | £3,015 | £6,601 |
| 10 | £8,854 | £5,961 | £14,815 |
| 15 | £16,595 | £8,837 | £25,432 |
| 20 | £27,966 | £11,644 | £39,609 |
These figures show how solar panels and battery storage can provide value over the long term.
Environmental Benefits
The financial savings are only part of the story.
Generating renewable electricity at home also helps reduce the property’s environmental impact.
Every Year:
- Approximately 1 tonne of CO₂ emissions reduced
- 155% offset of CO₂, SOₓ and NOₓ emissions
Over the System Lifetime:
The environmental impact is equivalent to:
- 42,428km of car travel avoided
- 273 trees planted
- 30 long-haul flights avoided
Therefore, this installation helps the homeowner save money while also reducing carbon emissions.
