FAQs
How long does installation take?+
Installation usually happens 7–21 working days after you order. If your grid operator needs to approve it (G99), allow an extra 10–21 working days.
What's included in the price?+
The battery, inverter, MCS-certified installation, all cabling and isolators, meter fitting, grid (DNO) notification, commissioning, app setup and a full handover.
What could cost extra?+
Usually nothing. The only common extra is a consumer unit (fuse box) upgrade, £300–£500 at cost, and we always tell you first.
Who installs the battery?+
Emerald Solar, an MCS-certified installer (MCS NIC-602139), with a 2-year workmanship warranty.
Do I need solar panels?+
No. A battery can charge on a cheap overnight tariff and power your home at peak times. All our systems can also take solar panels.
How are the savings worked out?+
It's an estimate based on charging overnight and using that energy at peak times, saving around 18p per kWh. Your real savings depend on your usage and tariff.
What happens after I order?+
Our team contacts you within 2 working days, asks for photos of your fuse box and sends a proposal to sign. Your order is confirmed once the proposal is signed.
