Home battery storage systems store excess electricity generated by your solar panels during the day, so you can use it later, typically in the evening when energy demand is highest.

Without a battery:

• Excess electricity is exported to the grid
• You buy electricity back at higher rates later

With a battery:

• More of your own energy is used on-site
• Grid dependency is reduced
• Exposure to peak tariffs is minimised

This increases self-consumption and improves overall return on investment.

Solar & Battery Systems Designed Together

Battery storage performs best when integrated with solar PV and the wider energy profile of the property.

Our process includes:

Property & Usage Assessment

We review electricity consumption patterns, roof orientation, shading, and future energy demand — including EV charging or heat pumps.

System-Led Design

We design solar panels, inverters and battery storage as a coherent system, optimising:

• Self-consumption

• Export capability

• Load balancing

• Future expandability

Integration With Fabric & Heating

Battery sizing and solar generation are aligned with insulation levels and heating upgrades to avoid oversizing or underperformance.

Compliant Installation & Commissioning

All battery storage installations are delivered with full commissioning, performance checks, and handover documentation.

Battery Storage for Existing Solar Systems

If you already have solar panels installed, adding battery storage can significantly improve savings.

We assess:

• Current inverter compatibility
• Generation data
• Export levels
• Property demand

We then recommend a battery system that aligns with your usage profile and financial objectives.

Many homeowners in Cardiff and the Vale of Glamorgan are retrofitting battery storage to maximise value from existing solar installations.

Battery Storage With Power Backup Options

Modern battery systems can also provide limited backup during power interruptions.

While not a full off-grid solution, battery systems can:

• Maintain essential circuits
• Support lighting and refrigeration
• Provide short-term resilience during outages

This is increasingly important as households electrify heating and transport.
