Why compare quotes for this
Battery storage is a significant investment and performance can vary widely between products and installers. Multiple quotes reveal differences in usable capacity, round-trip efficiency, warranty terms and installation quality — helping you avoid over-paying or ending up with a system that doesn't meet your evening-time demand.
Frequently asked questions
Do I need a battery with solar panels?
A battery is not mandatory, but it lets you store excess daytime generation for use after sunset, increasing self-consumption and reducing grid imports. If you're on a time-of-use tariff or want backup power during outages, a battery adds clear financial and resilience benefits.
How much does solar battery storage cost?
Cost depends on capacity, chemistry, brand and installation complexity, so a single figure can't represent every project. Getting several quotes is the best way to see realistic pricing for your specific requirements.
Can I add a battery to an existing solar panel system?
Yes — most existing PV arrays can be retrofitted with a compatible battery and hybrid inverter, provided the current inverter supports AC-coupling or a separate battery inverter is installed. An installer will check your system's voltage and available space before confirming feasibility.
How long do solar batteries last?
Modern lithium-ion batteries typically retain 70-80% of their original capacity after 10-15 years or several thousand full cycles, whichever comes first. Warranty periods of around 10 years are common. Regular monitoring and avoiding deep discharges help maximise lifespan.
