Solar Battery Storage System

IDEAL Solar and Electrical's cutting-edge battery solutions are designed to store the surplus energy your solar panels generate.

Tailored to both residential and commercial applications, our batteries are selected to perfectly match your system's size and your usage patterns, boosting your energy independence.

What is a Solar Battery?

A solar battery is a storage system that captures and stores excess energy generated by your solar panels. During the day, when your panels produce more electricity than your home needs, the surplus energy is directed to the battery instead of being sent back to the grid. This stored energy can then be used later—at night or during periods of low sunlight—ensuring you have a reliable power source whenever you need it. Essentially, a solar battery acts as a reserve, optimising your solar panel system’s efficiency and providing you with greater control over your energy consumption.

Key Benefits Of Solar Battery Storage

Greater Energy Independence

Instead of sending your unused electricity back to the grid, store it for later use—especially handy when electricity prices are higher. We’ll help you choose a battery that’s perfectly matched to your system and energy use, whether for your home or business.

Energy Storage

The extra energy your solar panels produce is stored in the battery, ensuring you have power even when needed.

Automatic Use and Monitoring

Your battery can be set to automatically activate when your solar panels aren’t generating power, allowing you to manage your energy use effortlessly. With our Solar PV system app, you can easily monitor your energy consumption and storage, track your savings, and ensure you’re maximising the benefits of your solar system—all from the convenience of your phone.

Custom-Fit

The size and capacity of your battery are customised based on your solar system and energy needs, ensuring it’s the perfect solution for you.

Long-Term Savings

With rising energy prices, investing in a solar battery is a savvy way to save money over time and gain control over your home’s energy consumption. By charging your battery during lower night-time rates, which are typically one-third of what you earn from selling surplus energy back to the grid, you can significantly enhance your energy efficiency. Think of your battery as a piggy bank for your energy savings—storing energy at a lower cost allows you to maximise the benefits of your solar investment and enjoy greater financial freedom.

VAT-Free Installation

Adding a solar battery when you install your panels means you won’t have to pay VAT, which adds up to big savings on your installation costs.

Environmental Impact

Maximise the use of clean, renewable energy, reducing your carbon footprint and supporting sustainable energy goals.

Why Get a Solar Battery?

Investing in a solar battery is a smart and easy way to make the most of your solar energy! By storing the energy your solar panels generate during the day, you can cut down on your reliance on the grid and take advantage of lower energy costs. This means you can use your stored energy during those peak pricing hours when electricity is most expensive, helping you save even more on your bills.

One of the best parts? In Ireland for 2024, there’s no VAT when you add a battery alongside your solar system, making this a fantastic time to invest! A solar battery not only boosts the efficiency of your solar setup but also offers you flexibility. If you’re out during the day and your panels are generating lots of energy, your battery will store that extra power for when you need it later. Plus, you can charge your battery during off-peak hours when rates are lower, allowing you to fill it up for a fraction of the usual cost.

And remember, solar panels don’t need direct sunlight to work—they can generate electricity from daylight, even on cloudy days! This means your battery will keep charging, ensuring you have power available whenever you need it.

With a solar battery, you’re not just saving money—you’re also making a positive impact on the environment. It’s a win-win for your wallet and our planet!

Some common FAQs we get about Solar Battery Systems

How much does a Solar Battery cost?

The cost of a solar battery typically starts at around €2,500, depending on the manufacturer and system requirements. For most home battery systems, prices generally range from €2,500 to €10,000, influenced by the size and capacity you choose.

What sizes are available for home batteries?

Home batteries typically come in various sizes, with the 5 kWh model being the most common for residential use. Larger options, such as 7.5 kWh and 10 kWh, are also available. If you need additional storage, batteries can be stacked to enhance your system’s capacity.

What type of batteries does IDEAL Solar and Electrical supply?

We supply high-quality home batteries from trusted manufacturers, including Huawei (LUNA2000-5-10-15-S0 | Smart String Energy Storage System | FusionSolar (huawei.com)) and Sigenergy. Both brands offer reliable and efficient energy storage systems that help you manage and control your energy consumption. These batteries can be installed alongside a new Solar PV system or added to an existing one.

Is there a grant for home batteries?

No, there is no longer a grant specifically for home batteries. However, you can still apply for a Solar PV grant of up to €2,100 when installing a battery alongside your solar panel system.

How can I monitor my power usage?

Once your system is installed, you can easily monitor your battery's performance through the Solar PV App (Fusion Solar or mySigen). The app connects via your home Wi-Fi, enabling you to access both live and cumulative energy data directly from your smartphone.

Will the battery installation disrupt my home?

When IDEAL Solar and Electrical installs your solar battery, the location is agreed upon in advance to ensure minimal disruption. Typically, the installation is completed on the same day as your solar PV installation, which usually takes one day. If the battery is added separately, this process generally takes just a couple of hours.

What warranty comes with Huawei and Sigenergy batteries?

Both Huawei and Sigenergy batteries come with robust warranties, typically covering 10 years or 10,000 charge cycles—whichever comes first. These warranties guarantee that the batteries will maintain at least 70% of their capacity after 10,000 cycles, ensuring long-term performance.

Will I still have power in the event of a power cut?

For safety reasons, the solar battery will not operate during a power cut. However, a backup reserve unit is available as an optional extra if you wish to have backup power during such situations.

Can I Retrofit a Battery or Add More Later?

Yes, you can! However, it’s important to note that this is only possible if you initially installed a hybrid inverter. Most domestic solar PV systems that don’t currently have a battery typically use a standard inverter or micro-inverter, which won’t support a battery.
