Solar PV and Battery Storage for Braintree Home


Solar installation on a pitched roof

Project Overview

In 2023, SolarTherm UK completed a high performance residential solar installation for a family home in Braintree, Essex. The goal was clear: reduce rising electricity costs, increase energy independence and future proof the property against ongoing energy price volatility.

By combining premium solar technology with advanced battery storage, the homeowner now benefits from significantly lower energy bills and greater control over their electricity usage.

System Specification

  • System Size: 5.74kWp
  • Panels: 16 x Amerisolar 410W
  • Inverter: SolarEdge with power optimisers
  • Battery Storage: 7.2kWh Voltsmile v5
  • Installation Date: May 2023

This system was carefully designed to maximise generation throughout the day while ensuring surplus energy could be stored and used when needed – particularly during evenings and peak tariff periods.

Why This System Works

A key feature of this installation is the SolarEdge inverter with power optimisers, which allows each panel to operate independently. This is particularly beneficial for residential properties where shading, roof angles or orientation might otherwise impact overall performance.

The addition of a 7.2kWh battery system enables the homeowner to store unused solar energy rather than exporting it back to the grid. This dramatically increases self-consumption and enhances overall savings.

Performance and Savings

The results from this installation have been strong from the outset:

  • First year savings: £1,309
  • Projected 25 year savings: £67,198
  • Estimated payback period: 10 years

These figures demonstrate the long term financial value of investing in a well designed solar and battery system – particularly as UK energy prices remain unpredictable.

Homeowner Outcome

Since installation, the homeowner has experienced:

  • Reduced reliance on grid electricity
  • Lower and more predictable energy bills
  • Greater protection from future price increases
  • Improved overall energy efficiency

By generating and storing their own electricity, they are now far less exposed to fluctuations in wholesale energy markets.
