Solar Storage Batteries
Solar Storage Batteries: Powering Sustainable Properties in the UK
As the UK accelerates its transition to a low-carbon future, solar energy is playing a pivotal role in driving sustainability within the built environment. For landlords, property managers, and businesses, integrating solar power is not just an environmental statement—it’s a strategic decision that can reduce costs, increase property value, and support compliance with evolving regulations. However, to truly maximise the benefits of solar panels, one crucial component must not be overlooked: solar storage batteries.
In this comprehensive guide, Eco Approach Ltd explores what solar storage batteries are, how they work, their benefits for property compliance and efficiency, and why they are becoming essential for forward-thinking property professionals across the UK.
What Are Solar Storage Batteries?
Solar storage batteries, often referred to as solar battery storage systems, are devices that store excess electricity generated by solar panels. Instead of sending surplus energy back to the grid, these batteries allow property owners to retain and use solar energy when it’s needed most—such as during the evening, on cloudy days, or during power outages.
How Do Solar Storage Batteries Work?
1. Daytime Generation: Solar panels convert sunlight into electricity, typically producing more than a property can use during daylight hours.
2. Battery Charging: Excess electricity charges the solar battery.
3. Energy Storage: The battery stores this energy for later use.
4. Night-time or Peak Use: When solar generation drops (e.g., at night), the property draws power from the battery instead of the grid.
5. Grid Interaction: If the battery is depleted, the property automatically switches to grid electricity.
Why Are Solar Storage Batteries Important for UK Properties?
1. Optimising Self-Consumption
The UK’s climate means solar generation can be variable. By storing surplus energy, batteries enable properties to use more of their own solar power, increasing self-consumption rates from around 30% to over 70%. This reduces reliance on grid electricity and makes solar investments more cost-effective.
2. Reducing Energy Bills
With rising energy prices, using stored solar power during peak tariff periods can significantly cut electricity costs. Some advanced systems also allow for “time-of-use” optimisation, charging batteries from the grid when prices are low and discharging when rates are high.
3. Supporting Compliance and Sustainability Goals
For property managers and landlords, demonstrating a commitment to sustainability is increasingly important for tenants, investors, and regulatory bodies. Solar storage batteries can help improve a building’s Energy Performance Certificate (EPC) rating, support compliance with MEES (Minimum Energy Efficiency Standards), and contribute to net-zero targets.
4. Enhancing Resilience and Safety
Battery storage provides backup power during outages, ensuring critical systems remain operational. This is particularly valuable for commercial properties, HMOs, or sites with vulnerable occupants.
Types of Solar Storage Batteries
Understanding the different battery technologies is key to selecting the right solution for your property:
Lithium-Ion Batteries
– Most common for residential and commercial use
– High energy density, long lifespan (10+ years), fast charging
– Maintenance-free and compact
– Examples: Tesla Powerwall, LG Chem RESU
Lead-Acid Batteries
– Traditional technology, lower upfront cost
– Shorter lifespan, larger and heavier
– Often used for off-grid or backup applications
Flow Batteries
– Emerging technology with long cycle life
– More suitable for large-scale or commercial installations
Key Considerations for UK Property Professionals
1. System Sizing and Integration
Battery capacity should be matched to the property’s energy usage patterns and the size of the solar PV system. Oversizing can lead to unnecessary costs, while undersizing may limit benefits.
2. Regulatory Compliance
While installing battery storage is not currently a legal requirement, it can support compliance with several UK regulations:
– EPC Improvements: Battery storage can contribute to higher EPC ratings, now crucial for letting properties.
– Building Regulations (Part L): Improved energy efficiency helps meet updated requirements for new and existing buildings.
– Fire Safety: Proper installation and certification are essential to meet fire risk assessment standards.
3. Installation and Certification
Battery installations must be carried out by qualified professionals, ideally those certified under the Microgeneration Certification Scheme (MCS) or similar. This ensures safety, compliance, and eligibility for incentives.
4. Maintenance and Monitoring
Modern battery systems require minimal maintenance but benefit from regular inspections to ensure optimal performance and safety—services that Eco Approach can coordinate as part of ongoing compliance management.
Financial Incentives and ROI
Smart Export Guarantee (SEG)
The SEG allows properties to earn money by exporting surplus solar electricity to the grid. With battery storage, you can control when and how much you export, maximising returns.
VAT Reductions
As of 2022, VAT on battery storage installed alongside solar panels is zero-rated, reducing upfront costs for homeowners and landlords.
Increased Property Value
Properties with solar and battery systems are more attractive to tenants and buyers, offering future-proofing against rising energy costs and tightening regulations.
Common Questions About Solar Storage Batteries
Are Solar Batteries Worth It in the UK?
For many properties, especially those with high evening or overnight electricity use, batteries can deliver significant savings and sustainability benefits. The payback period varies but is shortening as technology costs fall and energy prices rise.
How Long Do Solar Batteries Last?
Most lithium-ion batteries come with warranties of 10 years or more. Actual lifespan depends on usage, but many systems last 12-15 years with proper care.
Can Batteries Be Retrofitted to Existing Solar Panels?
Yes, most modern battery systems can be integrated with existing PV installations, subject to compatibility and electrical checks.
Is Planning Permission Needed?
In most cases, battery storage is considered “permitted development” for residential properties, but exceptions exist for listed buildings or conservation areas.
