Location: Barnstaple – Solar PV, Battery Storage & ASHP Installation
Project Overview
VIA Energy successfully delivered a complete renewable energy solution for a residential property in Barnstaple, combining high-performance solar PV panels, battery storage and an air source heat pump system.
The project was designed to significantly reduce the homeowner’s reliance on grid electricity and LPG heating, lower annual energy bills, and cut carbon emissions – preparing the property for the future against rising energy costs.
Client Objectives
The homeowner wanted to:
Reduce long-term energy bills
Replace their existing LP heating system with a low-carbon alternative
Maximise self-consumption of renewable energy
Increase energy independence
Lower their environmental impact
Install a future-ready system capable of supporting electric heating and appliances
The Solution
To meet these goals, we designed and installed a fullt integrated renewable system, including:
Solar PV System
Size: 16.065 kWp
Panels installed: 27 x JA Solar 595W high-efficiency panels
Estimated annual generation: 14,475 kWh
The roof allowed for multiple panel orientations, ensuring strong year-round energy production.
This allows excess solar energy generated during the day to be stored and used in the evening and overnight, increasing self-consumption and reducing import from the grid.
Air Source Heat Pump
Model: Vaillant aroTHERM Plus 12kW
Function: Provides 100% of the home’s space heating and hot water
Seasonal efficiency (SCOP): up to 3.8
The heat pump replaced the home’s LPG heating system, delivering a cleaner, more efficient solution with lower running costs and reduced emissions.
System Performance & Environmental Impact
The installed system is expected to deliver outstanding performance:
Annual solar generation: 14,475 kWh
Grid independence: approx.. 46%
Carbon Reduction
Around 4 tonnes of CO2 avoided per year – this is equivalent to:
The installation supports the homeowner’s transition to a low-carbon lifestyle while making meaningful environmental contributions.
Financial Benefits
The system was designed to deliver optimum long-term savings:
Estimated annual electricity bill savings: £2,422
Total system investment: £25,976
Estimated lifetime savings: £55,875
Payback period: approx. 11 years
Net savings over system lifetime: £29,899
Savings are enhanced through:
Reduced electricity imports
Battery optimisation
Smart Export Guarantee (SEG) payments for exported electricity
Protection against rising energy prices
Installation Process
Our team managed the full project from design through to commissioning
Initial site survey and energy assessment
System design tailored to roof layout and in accordance with household demand
Professional installation of solar PV, battery storage and heat pump
Full testing and MCS certification
Customer training on system monitoring and controls
The installation was completed efficiently with minimal disruption to the household.
Results
The completed system now provides:
Clean renewable electricity
Low-carbon heating and hot water
Reduced reliance on fossil fuels
Long-term cost savings
Improved energy security
A future-proof energy solution ready for EV charging and smart tariffs
Client Feedback
“We wanted to cut our grid us to as low as possible with solar, batteries and an air source heat pump. Although the installation happened in the middle of winter we have been very pleased with the outcome. The pipework is as tidy as I have seen anyone do. Very happy to recommend Via Energy who did a great job for us.”
