Frequently Asked Questions
Do I need an electrician for solar battery installation?
Yes. Battery storage installation must be carried out by a qualified electrician who can certify the work under Part P Building Regulations. The electrical connection to your consumer unit and any modifications require proper certification for safety and warranty validity.
How much can I save with solar battery storage?
Typical savings are £400-800 per year for an average home. Battery storage allows you to use more of your solar generation (increasing self-consumption from ~30% to 70-80%) and take advantage of cheap overnight tariffs like Octopus Go.
Do I need to upgrade my consumer unit for battery storage?
Often yes. Many older consumer units don't have space for the additional circuits required for battery systems. We assess this during our free survey and include any upgrade costs in your quote.
What's the difference between AC and DC coupled batteries?
AC coupled batteries (like Tesla Powerwall) can be added to any existing solar system. DC coupled batteries connect directly to solar panels and are typically installed with new solar systems. Both work well - the best choice depends on your existing setup.
How long does solar battery installation take?
Most battery storage installations take 1-2 days. This includes mounting the battery, running cables to the consumer unit, configuring the inverter, and commissioning the system. More complex installations may take longer.
