Is solar battery storage worth it in Northern Ireland?

It depends on your usage curve, tariff design and solar generation. If you export surplus during the day then use grid power at peak evening rates, batteries can shift economics meaningfully-we model stacked savings transparently.

Can you add batteries to an existing domestic solar PV system?

Usually yes-we assess inverter compatibility (AC‑ vs DC‑coupled architectures), metering and inverter capacity. Retrofits are common across Northern Ireland installs completed by other MCS contractors too.

What about tariffs and nighttime charging?

Some tariffs incentivise nighttime grid imports to fill storage-as long as metering and safeguards align with installer warranty terms. We clarify those trade-offs upfront.

Solar battery storage in Northern Ireland

Battery technology has matured-costs have fallen whilst safety and longevity have improved. For homes and businesses across Northern Ireland, adding storage can increase self-use of rooftop solar and help you optimise import tariffs when wholesale and retail rates diverge sharply.

What Is Battery Storage?

There is now a large range of lithium battery storage to choose from costing from as low as around 5p per kWh of storage.

With the availability now of smart grids and cheaper night tariffs, not only can we save you money by storing free electric from your solar PV to use at night time-you can also buy electric at half price at night time in winter months for use at other times when electric is costing double.

At Apollo Solar, having access to the full range of products on the market, we will guide you towards the best storage option for your usage-whether that's a small domestic battery or a large commercial system.
