Billericay homeowner set to save £52k over 25 years


Solar installation on pitched roof

Project Overview

A homeowner in Billericay, Essex approached SolarTherm UK looking to reduce rising energy bills and gain greater control over their electricity usage. With energy prices still high, the goal was to future proof the property with a reliable solar and battery solution.

Following a full site survey, we designed and installed a high performance solar PV system tailored to the property’s energy consumption and roof orientation.

System Specification

  • Install date: February 2023
  • System size: 5.60 kWp
  • Solar panels: 14x JA Solar 400W panels
  • Inverter: LuxPower hybrid inverter
  • Battery storage: Voltsmile 4.8kWh battery
  • Additional features: galvanised anti-bird mesh and EPS (Emergency Power Supply) sockets

Performance and Savings

  • First year savings: £1,012
  • 25 Year projected savings: £52,947
  • Payback period: 10 years

This system enables the homeowner to generate their own electricity during the day and store excess energy for use in the evening – significantly reducing reliance on the grid.

With UK households typically saving £600-£1,400 per year depending on system size and battery usage, this installation sits at the higher end of performance due to efficient system design and battery integration.

Key Benefits

Lower Energy Bills –by generating and storing their own electricity, the homeowner has dramatically reduced their monthly energy costs.

Energy Independence – battery storage allows for greater self-consumption of solar energy, protecting against rising energy prices and reducing grid reliance.

Backup Power – the inclusion of EPS sockets ensures essential appliances can still be powered during grid outages – adding an extra layer of energy security.

Long Term Investment – with a 10 year payback period and over £50,000 in projected savings, this system delivers strong long term ROI, in line with typical UK solar payback ranges of 6-10 years.

Carbon Reduction – solar PV systems can save around 1 tonne of CO₂ per year, helping homeowners significantly reduce their environmental impact.

Installation Highlights

The installation was completed efficiently with minimal disruption to the homeowner. The addition of galvanised anti-bird mesh ensures long term system protection without compromising aesthetics. All components were installed to the highest standards, ensuring optimal system performance and longevity.
