Choose a time of day to see where your power comes from, and where it goes.
Your panels power whatever is running at home. Anything spare charges the battery, and only once it is full does the rest go to the grid, where an export tariff pays you for it.
Cooking, lights and the TV run on the energy you stored during the day, instead of grid power at peak rates.
On a smart tariff, the battery and your car charge from the grid in the cheapest hours, so you start the next day full, even in winter.
Tesla's home battery, with a built-in solar inverter, optional backup in a power cut and simple control from the app.

Add a battery to my solarWe looked at the solar and battery systems we have sold for between £9,000 and £10,000. This is what a typical one costs, saves in its first year, and how long it takes to pay for itself.
Median projections from 64 customer proposals, assuming electricity prices rise 7% a year. With no price rises, typical payback is around 8 years.

What happens between your first enquiry and a working system.
Tell us about your home. We design your system and send you a fixed-price proposal.
Once you accept your proposal, we apply to your network operator for you.
Once your network operator approves, we agree a date and our own installation team fits your system, typically in one to two working days.
Your certificates, MCS registration and a walk-through of your system and app.
Read what our customers say once the scaffolding comes down.
Every system is fitted by our own installation teams, not subcontractors. Wherever you are in England or Wales, the same standards apply.
Most homes are. For solar, we look at which way your roof faces, its pitch, any shading and its condition. South is best, but east and west roofs work well, and a shallow north-facing roof can still make sense with a battery. A battery needs wall space inside or outside, often in a garage or utility room. If your roof is not suitable, a battery on its own can still work on a smart tariff.
Yes, in most cases. We check your existing panels and inverter, then recommend a battery that works alongside them, whoever installed your solar.
We confirm your installation date once your survey is back. If your system needs your network operator's approval first, we confirm it once that approval arrives. The fitting itself typically takes one to two working days, with scaffolding up beforehand and down shortly after. We tell you at the proposal stage whether your system needs that approval.
We handle all of it. Depending on the size of your system, we either notify your network operator after installation (G98) or apply for approval before it (G99). We register the system with MCS, which you need to be paid for the electricity you export, and issue your electrical certificates. At handover you get every certificate and warranty document together.
Through the manufacturer's app: the Tesla app for Powerwall or mySigen for SigenStor. You can see what your panels are generating, how full your battery is and what you are using or exporting, live on your phone. You can also change how the battery behaves, such as how much charge it keeps back for a power cut. We set the app up with you at handover.
We aim to get back to every enquiry within one working day. Someone from our team calls you to talk through your home and what you want from a system. Have a recent energy bill to hand if you can, as it helps us size the system properly. We then send you a design and proposal to look over in your own time. Nothing is booked until you say yes.
No. There is no deposit to get started: payment is due once your installation is complete. We accept bank transfer (BACS) and major credit and debit cards, but not American Express.
