Solar Panel and Battery Upgrade Installation in Aberdare

Smart Energy Homes recently completed a solar panel and battery storage upgrade at a property in Aberdare, helping the homeowner make even greater use of renewable energy.

Unlike many solar installations, this project involved enhancing an existing renewable energy system rather than starting from scratch. The homeowner already had a 4kW solar PV system, a 10kWh Duracell battery and a 3.6kW inverter installed approximately eight years ago. However, with energy habits evolving and renewable technology advancing, they wanted to explore expanding the system to generate and store even more electricity.

Following a detailed survey, our team designed a solution focused on increasing solar generation, improving battery storage capacity and maximising long-term savings.

Understanding the Property

The property is a four-bedroom semi-detached home in Aberdare, Rhondda Cynon Taf, built between 1940 and 1969.

The home already benefited from several renewable technologies, including an existing solar PV system, battery storage and a Pod Point EV charger. The homeowner was highly engaged with their energy usage and wanted to increase the amount of self-generated electricity available to the property.

Property Overview

  • Location: Aberdare, Rhondda Cynon Taf
  • Property Type: Four-Bedroom Semi-Detached House
  • Construction Period: 1940-1969
  • Current Heating System: Gas
  • Existing Solar System: 4kW Solar PV System
  • Existing Battery Storage: 10kWh Duracell Battery
  • Existing EV Charger: Pod Point
  • Roof Type: Standard Pitched Roof
  • Roof Direction: South Facing
  • Customer Goal: Expand solar generation and battery capacity

The Challenge

The homeowner was already seeing the benefits of solar energy but felt their existing system no longer made full use of the available roof space.

They approached Smart Energy Homes looking to:

Increase solar generation
Expand battery storage capacity
Improve self-consumption
Support future household energy demand
Reduce reliance on imported electricity

With a strong south-facing roof and existing renewable infrastructure already in place, the property offered excellent potential for a system upgrade.

The Recommended Solution

Following our survey, Smart Energy Homes recommended expanding the property’s solar and battery storage capabilities.

The proposed system was designed to complement the existing installation while increasing overall performance and storage capacity.

Upgrade Objectives

Additional solar panel capacity
Increased battery storage
Improved renewable energy utilisation
Greater energy independence
Future-proofing the property

Battery storage formed a key part of the proposal, helping ensure more of the electricity generated by the solar panels remains available for use within the home.

Why Upgrade an Existing Solar System?

Many early solar adopters are now choosing to enhance systems installed several years ago.

Advances in battery technology and panel efficiency mean homeowners can often generate and store significantly more energy than was previously possible.

Benefits of upgrading an existing system can include:

  • Increased solar generation
  • Greater battery capacity
  • Lower electricity bills
  • Improved energy independence
  • Reduced reliance on the grid
  • Better support for EV charging
  • Future-ready renewable technology

For households already benefiting from solar, expanding an existing system is often a cost-effective route to further savings.

Installation Process

The Smart Energy Homes team carried out a detailed assessment of the existing installation before developing a tailored upgrade solution.

The project included:

Existing system assessment
Roof suitability review
Battery storage recommendations
Solar generation modelling
Upgrade design and specification
Installation and commissioning

Following completion, the system was tested and optimised to ensure maximum performance.

Existing Renewable Technology

A particularly interesting aspect of this project was the homeowner’s existing renewable setup.

The property already featured:

Solar PV generation
Duracell battery storage
EV charging infrastructure

By building on these technologies rather than replacing them entirely, the homeowner was able to maximise the value of their previous investment while continuing their journey towards greater energy independence.
