Solar PV batteries allow you to store excess electricity generated by your solar panels, so it can be used when it’s needed most. Whether you’re working on a new renewable installation or upgrading an existing system, battery storage helps maximise efficiency, reduce reliance on the grid, and improve long-term energy performance.

Why Invest in Solar PV Battery Storage?
Battery storage is becoming an increasingly common addition to solar installations, driven by rising energy costs and a greater focus on energy independence. Without a battery, excess energy is typically exported to the grid.
Battery storage allows that energy to be retained and used when demand is higher; using stored electricity instead of importing from the grid can help lower ongoing energy costs, particularly during peak tariff periods. Battery systems can also provide backup support during power outages (depending on system configuration), helping maintain essential supply. As energy pricing structures and grid reliance evolve, energy storage helps prepare properties for a more flexible, low-carbon energy system.
Return on Investment
The payback period for solar PV batteries will vary depending on system size, usage patterns, and energy tariffs. In many cases, systems are expected to deliver a return over several years through reduced energy bills and improved efficiency, particularly when paired with a well-sized solar PV array.
Types of Solar PV Batteries
Solar PV battery systems are available in a range of configurations to suit different property sizes and energy demands.
Modular Battery Systems
Allow additional battery units to be added over time.
- Scalable to suit growing energy demand
- Suitable for both domestic and commercial use
- Flexible installation options
Integrated Storage Systems
Designed to work seamlessly with specific inverters or as part of a complete package.
- Simplified specification and installation
- Optimised system compatibility
- Often used in new installations
High-Capacity Storage
Larger capacity batteries are typically used in commercial settings or high-demand residential properties.
- Supports greater energy usage
- Suitable for properties with higher load requirements
- Can be configured as part of larger systems

Installation: Trade vs Homeowners
Solar PV battery systems must be installed by qualified professionals, typically electricians or renewable specialists with relevant certifications. Installation involves integrating the battery with the existing solar PV system, inverter, and electrical supply, while ensuring compliance with current regulations and safety standards.
Homeowners should always use a qualified installer for solar PV battery systems. Professional installation ensures the system is safe, compliant, and correctly configured to maximise performance.
City Plumbing branches can support both installers and homeowners with product selection and guidance at the specification stage.
Residential vs Commercial Applications
Solar PV batteries can be used across a range of property types, but system design will vary depending on the application.
Residential: Battery systems are typically sized to store excess generation from rooftop solar panels. This allows energy to be used during the evening or overnight, helping to reduce reliance on grid electricity. In most cases, these systems are installed as part of a new solar PV setup or added later as a retrofit to improve overall efficiency.
Commercial: In settings such as schools, offices, or retail spaces, battery storage is used to manage higher and more variable energy demand. These systems generally require larger capacity units and may form part of a wider energy management strategy, including peak load management and cost control.
The key difference lies in system size, complexity, and usage patterns, with commercial installations typically requiring more detailed specification and planning.
