Solar Battery Storage Systems in Peterhead & Aberdeenshire
Store what your panels generate through the day and use it in the evening — fitted alongside new panels or added to a system you already have.
Storing Daytime Generation for Evening Use
Solar panels only generate while there's daylight, but most households use more power in the evening than through the middle of the day. A battery closes that gap — it stores what your panels generate at midday and lets you draw it down after work, at dinner time and into the evening instead of buying it back from the grid at that point. Sizing a battery is about your evening usage pattern more than your panel output; a bigger battery than your household can realistically draw down through a winter evening is money spent for no extra benefit. Most domestic batteries we fit range from around 5kWh to 10kWh, and a battery doesn't need to cover a full day's use — just enough to bridge the evening peak.
Retrofitting a Battery vs Fitting Both Together
Plenty of the batteries we fit go onto systems installed years ago, sometimes by another company. Retrofitting means checking what inverter you've got first — some accept a battery directly, others need a separate battery inverter — and confirming your consumer unit and metering can accommodate it. Fitting both together at once is simpler: one inverter spec, one set of cabling, one visit for commissioning, and it's usually the cheaper route if you know from the start you want storage. Either way we test the system to confirm it's actually charging and discharging as expected before we leave.

- Consumer unit and metering setup
- Wall or floor space for the battery unit
- Cable route between panels, inverter and battery
Backup Power and Short Winter Daylight
Some battery systems can provide backup power to the house during a grid outage, though this needs specific hardware fitted at install — it isn't automatic on every system, so tell us upfront if outage backup matters to you. This is especially relevant here: Aberdeenshire winters mean daylight from roughly 9am to 4pm in December, so a battery has far less to work with over winter than in summer, when there's generation to spare well into the evening. We size systems with that swing in mind rather than promising the same evening coverage year-round, and backup power typically keeps essentials like the fridge, lighting and broadband running rather than the whole house, depending on battery size. Battery storage pairs naturally with both our residential and commercial and agricultural installations.
Frequently Asked Questions
Can I add a battery to my existing solar panels?
In most cases yes. We check your existing inverter and consumer unit at survey to confirm compatibility and quote for whichever battery inverter setup suits your system.
Will the battery keep my power on during a cut?
Only if backup hardware is fitted at installation — this isn't automatic on every system. Tell us if outage backup matters to you and we'll spec accordingly.
How long will a battery run my house for in winter?
It depends on the battery size and your usage, but expect less runway than in summer — short winter daylight means less generation banked to draw down from.
