How it works

We compare your electricity plan, model whether a home battery and optional solar would save you money, and - if the numbers work and you want to proceed - install the system. Every stage before you sign a contract is free.

Why a battery saves you money

Electricity does not cost the same all day. It is cheapest overnight when demand is low, and most expensive in the early evening when everyone gets home. A battery lets you buy at the cheap end of that curve and spend at the expensive end - and keeps the lights on when the grid goes down.

A day of energy arbitrageGrid electricity prices are lowest overnight and peak in the early evening. The home battery charges during the cheap overnight window and discharges through the expensive evening peak, so the household avoids buying power at the highest rates.ChargeDischargeGrid price12am6am12pm6pm12amCheap overnight power charges the batteryThe battery covers the expensive evening peak

Model your home before anyone visits

Everything in this phase happens in your browser and costs nothing. You do not need an account to start.

  1. Tell us about your home

    Your ZIP code, current provider and plan, delivery utility, roughly how much electricity you use in a year, and how your home is heated and cooled. Anything you do not know, we estimate from your ZIP and home size.

  2. Set your priorities

    Lowest bill, backup power during outages, greener supply, or shortest payback. Your priorities change which options we put in front of you.

  3. See your options

    We model your usage against available plans and against battery and optional solar configurations, and show the estimated savings and payback period for each. You can download the full report as a PDF.

Stage 2At your home - free

A site visit with no obligation

Modelling only goes so far. Before anyone quotes you a price, we look at the actual building. The visit is free, and you can end it at any point.

  1. Book a time

    Pick a day and time on the site and confirm with a code we email you. No password and no account required. We assign the local admin nearest you and send you the appointment details.

  2. We survey the property

    We photograph your main service panel and meter, check the garage or utility space for the battery, and fly a drone over the roof to build a 3D model that tells us its real solar capacity.

  3. We talk through what we found

    You get our honest read on whether your home is suitable. Sometimes it is not, and we say so. If you would rather gather more information before deciding, that is a normal outcome and there is no charge either way.

Stage 3If you decide to go ahead

Contract, deposit, and permit

Nothing is charged until you have a written quote in hand and have chosen to sign it.

  1. You receive a written quote

    We email you a contract with the full system price and a schedule of progress payments. Financing is arranged by you directly, with your own bank or lender - securing it is your responsibility, and approval and terms are theirs.

  2. You sign and pay a $500 deposit

    A $500 USD good-faith deposit is due on signing. If you cancel within 7 days, the deposit is credited back in full, no questions asked. After day 7 it is non-refundable, because that is when we commit to buying your equipment.

  3. We file for your permit

    We apply to your local authority as soon as the contract is signed. Permit review times vary by jurisdiction and are the main reason one installation takes longer than another.

Stage 4Installation

From equipment order to commissioning

Roughly five to seven weeks from a signed contract to a working system, with permit approval the largest variable.

  1. Equipment is ordered on day 7

    Once your cancellation window closes we order your batteries, inverter, and sub-panel. Delivery from our supplier takes three to four weeks.

  2. Installation is scheduled

    A technician prepares the wall, then a licensed electrician wires the components. Installations are carried out by licensed contractors we engage and supervise.

  3. Your local inspector signs off

    The authority that issued your permit inspects the finished work. We do not commission a system that has not passed inspection.

  4. The system is commissioned

    Your system goes live, we walk you through operating it, and the remaining balance is billed per the schedule in your contract.

How long an installation takes

Typically five to seven weeks from a signed contract to a working system. Permit review times vary by jurisdiction and are the main reason one installation runs longer than another.

From signed contract to a working systemA timeline drawn to scale over about seven weeks. On day zero the contract is signed, a $500 deposit is taken and the permit is filed. The seven-day cancellation window closes on day seven, when equipment is ordered. Equipment arrives three to four weeks later, and the system is installed, inspected and commissioned by roughly week seven.7 days - deposit refunded in full if you cancelContract signed$500 deposit taken,permit filedEquipment orderedCancellation windowclosesEquipment arrives3–4 weeks from orderSystem commissionedInstalled, inspected,balance billed

What this costs you

Comparison and modelling
Free. No account needed to see your estimate.
Site visit
Free, with no obligation to proceed.
Deposit on signing
$500 USD, refundable in full within 7 days of signing.

The full system price is quoted in your contract after the site visit, alongside a schedule of progress payments. Savings estimates shown on this site are model-based and non-binding - they depend on your future usage and on rates we do not control. See our resources and FAQs for how the modelling works.

Following your installation

Once you have an order with us, it moves through the stages above in your account - visit scheduled, site visit completed, contract signed, deposit received, permit approved, equipment ordered, equipment in place, installed, finished. You can check where yours stands at any time under My Orders.
