Quick answer

Adding a battery to solar lets you store daytime generation for evenings and overnight, lifting self-consumption from roughly 30–50% to 70–90%. On the South Coast a solar-and-battery system typically costs £9,000–£16,000 and provides backup power during outages.

Solar photovoltaic (PV) systems capture daylight and convert it into electricity that you can use in your home. A combined system pairs solar panels with battery storage, prioritising home power use first, then charging the battery with excess energy.

During the evening and overnight, your home draws from stored battery energy before importing from the grid. Surplus electricity generated during the day can also be exported to the grid, earning you money through the Smart Export Guarantee.

Battery systems can also be charged during cheaper off-peak periods using smart tariffs like Octopus Flux, then discharged during expensive peak hours — maximising your savings even beyond what solar alone can achieve.

We partner with Tesla, Sigenergy, GoodWe, EcoFlow, and Fox ESS to offer the right battery solution for every home. Each system is custom-designed around your consumption patterns, roof characteristics, and energy goals.

FAQ

Common Questions

How much battery storage do I need?
This depends on your energy usage patterns. A typical UK household uses 8–10 kWh per day. We analyse your actual consumption data to recommend the right battery capacity, typically between 5 kWh and 13.5 kWh for residential installations.
Can I charge the battery from the grid?
Yes. Smart tariffs like Octopus Flux allow your battery to charge from the grid during cheap off-peak hours (typically overnight) and discharge during expensive peak times, maximising savings even on cloudy days.
What happens during a power cut?
Many battery systems (including Tesla Powerwall) can provide backup power during outages. The system automatically switches to battery power, keeping essential circuits running until grid power is restored.
How long do batteries last?
Modern lithium-ion batteries are warranted for 10–15 years and typically last much longer. Tesla Powerwall, for example, is warranted to retain 70% capacity after 10 years of unlimited cycling.
