Solar and Re-Roof Installation Warrington: £1,880 Annual Savings with 54.24kWh Sigenergy Battery Storage
Every property has different energy requirements. That’s why the best solar systems are designed around how a home uses electricity rather than simply making the most of the available roof space. This Solar and Re-Roof Installation Warrington project demonstrates how combining a new roof with a premium solar PV and battery storage system can deliver long-term savings while future-proofing a home.
Installed by NRG Solar Ltd in Warrington (WA4), this project included a complete re-roof alongside a high-performance Sigenergy solar and battery system. As a result, the homeowner now benefits from a modern, energy-efficient roof and a renewable energy system designed to maximise savings for decades to come.
The system is expected to save approximately £1,880 per year on energy bills while reducing the annual electricity bill to just £339 after installation.
System Overview
Rather than installing solar panels onto an ageing roof, this project involved replacing the roof before fitting a high-performance solar PV and battery storage system.
System Specifications:
- 18 × AIKO 455W Solar Panels
- 8.19kWp Solar PV System
- 10kW Sigenergy SigenStor Hybrid Inverter
- 54.24kWh Sigenergy Battery Storage
- 6 × SigenStor BAT 10.0 Batteries
Together, these components create a complete home energy solution. During daylight hours, the AIKO solar panels generate renewable electricity, while the Sigenergy battery system stores surplus energy for use later in the day.
In addition, completing the re-roof before installation ensures the system is built on a durable roof that’s ready to support decades of renewable energy generation.
How This Solar and Battery Installation in Warrington Works
Throughout the day, the solar panels generate clean electricity from sunlight.
Firstly, the home uses this electricity to power appliances and reduce grid imports. Next, any surplus energy charges the Sigenergy battery storage system.
Later, when solar generation decreases, the stored electricity powers the home instead of importing expensive electricity from the grid.
As a result, the property achieves:
- 65% Self-Consumption
- 35% Electricity Exported to the Grid
This balance allows the homeowner to maximise the value of every unit of electricity generated while also earning income through the Smart Export Guarantee (SEG).
Key Benefits
✔ Generate renewable electricity throughout the year
✔ Store surplus solar energy for later use
✔ Reduce reliance on grid electricity
✔ Earn money through the Smart Export Guarantee
✔ Lower annual household energy bills
✔ Benefit from a brand-new roof built to last

Environmental Benefits
Alongside reducing energy bills, this installation also delivers significant environmental benefits.
Every Year
- Approximately 1 tonne of CO₂ emissions reduced
- 101% offset of CO₂, SOₓ and NOₓ emissions
Over the System Lifetime
- Equivalent to avoiding 42,330km of car travel
- Equivalent to planting 272 trees

Therefore, this system not only saves money but also helps reduce the property’s environmental impact for many years to come.
Why Combine a Re-Roof with Solar Panels?
Installing a new roof before fitting solar panels is often the smartest long-term investment.
Rather than needing to remove and reinstall solar panels in the future, homeowners can install both at the same time, saving money and avoiding unnecessary disruption.
At NRG Solar Ltd, we regularly complete re-roof and solar projects, ensuring every installation starts with a roof that’s built to last just as long as the solar system itself.
