Solar and Battery Installation Chorley: £1,349 Annual Savings with Sigenergy Battery Storage  

Every home uses electricity differently. Therefore, a solar system should be designed around the property’s energy needs, not simply the available roof space.

This Solar and Battery Installation Chorley project in Hale Grove, Chorley (PR7), shows how solar panels and battery storage can help reduce energy bills while generating clean electricity.

Installed by NRG Solar Ltd, this system combines 12 high-efficiency AIKO 490W solar panels with a 6kW Sigenergy inverter and 18.08kWh of battery storage.

The system is expected to provide £1,349 in annual energy bill savings, with an estimated payback period of 6 years and 11 months.


System Overview

This Hale Grove installation has been designed to generate renewable electricity throughout the year while helping the homeowner make better use of the energy produced.

System Specifications:

  • 12 × AIKO 490W solar panels
  • 5.88kWp solar PV system
  • 6kW Sigenergy inverter
  • 18.08kWh Sigenergy battery storage
  • 2 × SigenStor BAT 10.0 batteries

Together, these components create a complete solar and battery system for the property.

During daylight hours, the AIKO solar panels generate electricity from sunlight. Any surplus energy can then be stored in the Sigenergy batteries for use later.

As a result, the homeowner can use more of their own renewable electricity and reduce the amount of power they need to buy from the grid.


How This Solar and Battery Installation in Chorley Works

The solar panels generate electricity during the day. The property uses this electricity first, helping to reduce grid imports.

When solar generation is higher than household demand, the excess electricity can charge the battery system.

Later in the day, stored energy can be used to help power the home. This reduces the need to purchase electricity when the solar panels are no longer generating power.

For this installation, the expected energy split is:

  • 36% self-consumption
  • 64% exported to the grid

The system is therefore expected to export a significant amount of surplus electricity. This can provide an additional financial return through the Smart Export Guarantee.

Solar generation varies throughout the year. For this installation, generation is expected to be highest between April and September.

The strongest month is expected to be May, with average daily generation reaching approximately 25kWh.

June follows closely, with around 23.9kWh generated per day.

During these months, strong solar generation can provide more electricity than the home needs at certain times. The battery can store some of this surplus energy, while additional electricity can be exported to the grid.


Key Benefits of This Chorley Solar Installation

  • Generate renewable electricity at home
  • Store surplus solar energy for later
  • Reduce reliance on grid electricity
  • Export excess electricity to the grid
  • Lower annual energy bills
  • Improve household energy independence
  • Reduce carbon emissions

Financial Results

This installation has been designed to provide strong long-term financial benefits.

Estimated Annual Energy Bill Savings:

Approximately £1,349

Estimated Payback Period:

6 years and 11 months

Estimated Annual Energy Bill After Installation:

Approximately -£105

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 payments for surplus electricity exported to the grid through the Smart Export Guarantee.

Estimated Cumulative Bill Savings:

The projected financial return increases over time as the homeowner continues to generate and export renewable electricity.

Year Usage Savings Smart Export Guarantee Total Savings
1        £834             £515        £1,349
5        £4,896            £2,550        £7,447
10        £12,090            £5,036        £17,126
15        £22,658            £7,456        £30,114
20        £38,182           £9,812        £47,995

These figures show how a professionally designed solar and battery system can provide value over the long term.


Environmental Benefits

The financial savings are only one part of the benefit.

By generating renewable electricity at home, this installation also helps reduce the property’s carbon footprint.

Every Year:

  • Approximately 1 tonne of CO₂ reduced
  • 109% offset of CO₂, SOₓ and NOₓ emissions

Over the System Lifetime:

The environmental impact is equivalent to:

  • 40,603km of car travel avoided
  • 261 trees planted
  • 29 long-haul flights avoided

Therefore, the homeowner can reduce energy costs while also helping to lower their environmental impact.
