"Reviewing 1 week after installation. Installation happened without any issues, scaffolding had to be up and down within a few days as it was erected on neighbouring homes. Very efficient service, all installed within 6 hours and Solax app is great to show what is being generated. Early signs are that it is hopefully going to do as suggested in bringing bills right down. Project Solar were no the cheapest quote we had but Jonathan Wolf answered all the questions we had and went above and beyond to make sure we were happy with the system suggested. Currently very happy with the 12 panels and 12 KWH battery." - Trustpilot

"I had a great experience working with Sahil on my solar design. He was incredibly thorough in mapping out the roof for my new 10.6kWh SolaX battery system. He noticed potential shading issues from a neighboring roof that I hadn't fully considered and proactively redesigned the layout to maximize my generation. He even included free optimisers to ensure the system performs at its best despite the evening shade. Really impressed with the technical knowledge and the extra mile he went to ensure I got the best deal. Highly recommend asking for Sahil if you want a system that actually works for your specific home." - Trustpilot

Adding battery storage to your home can make a big difference to how you use and manage your energy. Instead of sending unused electricity back to the grid, a battery lets you store and use it when you need it most.
This can lead to greater control, savings and energy independence:
Lower electricity billsA solar battery allows you to use more of the energy your system generates, reducing the amount you need to buy from your supplier, especially during peak pricing hours.
Better use of solar energy
Without a battery, excess energy is often exported to the grid. With battery storage, you can keep that energy for later, making your system much more efficient.
Reduced reliance on the grid
By storing your own electricity, you become less dependent on energy suppliers and more protected from rising energy prices.
Backup power during outages
Some battery systems can provide electricity during a power cut, helping keep essential appliances running when the grid goes down.
Greater energy control
Many batteries come with smart monitoring apps, allowing you to track your energy usage and see exactly how and when your stored energy is used.
Lower carbon footprint
Using more of your own renewable energy helps reduce your household’s carbon emissions, making your home more environmentally friendly.
Choosing the right solar battery installer is just as important as choosing the battery itself. A good installer will make sure your system is safe, efficient and built to last, while a poor one can lead to problems down the line.
By knowing what to look for, you can feel more confident that you’re making the right decision for your home:
Look for an installer with proven experience in solar and battery storage systems. Companies that have been in the industry for several years are more likely to understand how to design and install systems that perform well.
It’s also a good sign if they specialise in battery storage, not just solar panels.
Always check that the installer has the right industry certifications, such as MCS (Microgeneration Certification Scheme). This ensures they meet recognised standards and that your system may qualify for government incentives or export schemes like the Smart Export Guarantee (SEG).
Reading independent reviews on platforms like Trustpilot can give you a clear picture of what to expect. Look for consistent feedback around installation quality, communication and aftercare, rather than focusing on just the overall score.
Not all solar batteries are the same, so it’s important to choose an installer that offers reliable, well-known brands. Check the warranty length for both the battery and the installation, as this can save you money and stress in the long run.
A good installer should offer clear, transparent pricing with no hidden costs. Many companies also provide finance options to help spread the cost which can make installing a solar battery more affordable.
Ongoing support is key. Choose an installer that offers strong aftercare, including help with system monitoring, maintenance and any issues that may arise. This ensures your system continues to run efficiently over time.
The brand of battery storage you choose can affect everything from performance and storage capacity to how much you save on your energy bills.
Glow Green works with a selection of trusted manufacturers, offering options to suit different homes and budgets:
Fox ESS is a popular choice for homeowners looking for a reliable and cost-effective battery. These systems are designed to store excess solar energy so you can use it later, helping to reduce reliance on the grid.
They also come with smart monitoring, so you can track your energy usage and performance in real time.
Duracell Energy brings the same trusted name into home energy storage, offering batteries built for long-lasting performance. These systems are designed to be easy to use and dependable, making them a solid option for households that want a straightforward way to store and use solar energy.
The Tesla Powerwall 3 is one of the most advanced options available, known for its high capacity and sleek design. It allows you to store more energy and use it when you need it most, whether that’s in the evening or during a power cut.
With intelligent energy management, it can automatically optimise how and when your stored energy is used.
Solar battery sizes can vary depending on your needs with most residential systems ranging from around 5kWh to 15kWh. Choosing the right size depends on your energy usage, the size of your solar system and how much energy you want to store.
Yes, it is possible to have battery storage without solar panels. In this case, the battery can be charged using electricity from the grid, often during off-peak hours when energy is cheaper, and then used later to help reduce electricity costs.
Most solar batteries last between 10 and 15 years, depending on the brand and how often they are used. Many manufacturers also provide warranties to guarantee performance over time.
Solar batteries can be worth it if you want to maximise the energy you generate and reduce your reliance on the grid. They are particularly beneficial for households that use more electricity in the evening when solar panels are not producing power.
A solar battery can power parts of your home, but whether it can run everything depends on its size and your energy usage. Larger systems can support more appliances but most households use batteries to cover essential usage in the evening.
