Battery Storage FAQs
Common questions about home battery storage — from choosing the right system and standalone batteries to backup power, costs, and existing GivEnergy support.
Are solar batteries worth it in Scotland without solar panels?
Yes, and it’s becoming one of the most popular ways to cut energy bills in Scottish homes. With 0% VAT on batteries and energy tariffs like Octopus Go offering electricity at around 9p/kWh overnight, you can charge your battery cheaply and use that stored power during peak hours when rates hit 30p+ per kWh. For a typical Scottish household, this can save £500-£800 per year—making the payback period around 5-7 years even without solar. You may also qualify for a Home Energy Scotland interest-free loan to spread the cost.
Which home battery system is best for Scottish homes?
The best battery depends on your usage, solar setup, backup-power needs, budget, and the manufacturer support available at the time of quote. Tesla Powerwall 3 remains a strong premium option for customers wanting high output, whole-home backup options, and a polished app ecosystem. For other homes, a modular battery from another supported manufacturer may be a better fit.
Can I get a battery without having solar panels?
Yes, absolutely. With the current 0% VAT incentive, standalone batteries are very popular. You can charge them overnight with cheap, off-peak electricity from the grid and use that stored energy during the day to save money.
What happens during a power cut?
Battery systems designed with backup capability can keep selected essential circuits running during a power cut. Backup needs to be specified during the design stage because not every battery installation includes it.
How long does a home battery last?
Quality lithium-ion batteries are designed for long-term use, but manufacturer warranties vary by brand and product. We'll explain the warranty terms available at the time of quote and separate those clearly from JME's own workmanship guarantee.
How big is a battery and where does it go?
Most home batteries are compact units, either wall-mounted or floor-standing, roughly the size of a small boiler. They are typically installed in a garage, utility room, or sometimes externally, depending on the model and a full safety assessment.
Can I add more battery capacity later on?
Yes, in many cases. We specialize in designing modular systems. Many of the batteries we install allow you to add more storage capacity in the future if your family’s energy needs grow.
