Solar and Battery Installation Chorley: £2,320 Estimated Annual Savings
Every property has different energy requirements. Therefore, the most effective solar systems are designed around how a household uses electricity rather than simply filling the available roof space.
This Solar and Battery Installation Chorley project at The Farthings, Chorley (PR7), demonstrates how high-efficiency AIKO solar panels and SolaX battery storage can work together to reduce electricity costs and increase energy independence.
Installed by NRG Solar Ltd, this bespoke renewable energy system includes an 8.37kWp solar PV system, a 7.5kW SolaX hybrid inverter, and 17.92kWh of battery storage.
As a result, the homeowner is expected to save approximately £2,320 per year on energy bills. The system also has an estimated payback period of just 4 years and 7 months.
System Overview
This Chorley solar installation combines high-efficiency solar generation with battery storage to help the homeowner make better use of their own renewable electricity.
System Specifications
- 18 × AIKO 465W solar panels
- 8.37kWp solar PV system
- 7.5kW SolaX X1-Hybrid G4 inverter
- 17.92kWh SolaX battery storage
- 1 × SolaX battery system
Together, these components create a complete home energy solution.
During daylight hours, the solar panels generate renewable electricity for the property. Meanwhile, the battery system stores surplus energy that the household does not immediately need.
Consequently, the homeowner can use more of their own solar electricity and reduce the amount of energy imported from the grid.
How This Solar and Battery Installation in Chorley Works
The AIKO solar panels generate electricity throughout the day.
Firstly, the home uses the available solar power to meet its immediate electricity demand. When generation exceeds household usage, the surplus electricity can charge the SolaX battery.
Later, when solar generation reduces, the stored energy can be used to help power the home.
This reduces the need to purchase electricity from the grid during the evening and other periods when solar generation is lower.
As a result, this system is expected to achieve:
- 80% self-consumption
- 20% electricity exported to the grid
The high self-consumption figure means that the homeowner is expected to use the majority of the electricity generated by the solar panels within the property.
Solar generation naturally changes throughout the seasons.
For this installation, the strongest levels of generation are expected between April and September.
Peak generation is expected to reach approximately 31.7kWh per day, with the next strongest month producing around 30.7kWh per day.
During these higher-generation months, the system can provide significant amounts of renewable electricity for the home while also charging the battery storage system.
Financial Results
One of the main benefits of this installation is its strong projected financial performance.
Estimated Annual Energy Bill Savings:
Approximately £2,320
Estimated Payback Period:
4 years and 7 months
Estimated Annual Energy Bill After Installation:
Approximately £637
In addition to reducing electricity costs, the system can generate further financial benefits through the Smart Export Guarantee.
Therefore, the overall return can continue to grow throughout the lifetime of the installation.
Estimated Cumulative Bill Savings
The figures below show the projected financial benefits from reduced electricity costs and Smart Export Guarantee payments.
| Year | Usage Savings | Smart Export Guarantee | Total Savings |
|---|---|---|---|
| Year 1 | £2,157 | £202 | £2,359 |
| Year 5 | £12,637 | £986 | £13,623 |
| Year 10 | £31,145 | £1,915 | £33,061 |
| Year 15 | £58,248 | £2,788 | £61,037 |
| Year 20 | £97,931 | £3,607 | £101,538 |
Over 20 years, the system is projected to deliver more than £101,000 in combined financial benefits.
These figures highlight the potential long-term value of investing in a carefully designed solar and battery system.
Environmental Benefits
Alongside the financial savings, this installation is expected to deliver significant environmental benefits.
Every Year:
The system is expected to:
- Reduce approximately 2 tonnes of CO₂ emissions
- Offset the equivalent of 80% of CO₂, SOₓ and NOₓ emissions
Over the System Lifetime:
The environmental impact is equivalent to:
- 51,883km of car travel avoided
- 334 trees planted
- 37 long-haul flights avoided
As a result, the homeowner can reduce household energy costs while also lowering the property’s environmental impact.
