For solar and battery professionals

From the customer's bill to every solar and battery size modelled hour by hour, a priced proposal and a deck with your logo. About 10 minutes to a credible estimate.

Free for one project. New companies get a 30-day Pro trial at signup.

Bill Data: the customer's bill is read line by line, with anything unsure flagged to check before you confirm it.

A Deck And An A4 Proposal

A PowerPoint deck from the Analysis and an editable A4 PowerPoint proposal from the Proposal. Your logo on both.

PowerPoint deck, 16:9, from the Analysis3 / 16
A4 PowerPoint proposal, one editable page per slide, from the Proposal2 / 11

The A4 PowerPoint and the customer link come from the Proposal, which models the site's own roof face (15° north) and so expects about 2% more solar than the Analysis, with a slightly shorter payback.

Why the numbers hold

Five Things The Other Quote Gets Wrong

Your customer is buying a payback, not panels. Amperage handles each of these in the same model.

  1. 01

    Demand Charges Left Out

    Solar barely touches them. Leave them out and the saving looks better than it is.

    How the bill is read
  2. 02

    A Flat Tariff

    Time-of-use windows decide what each kilowatt-hour is worth. Flatten them and the payback moves.

    Where tariffs come from
  3. 03

    Sized To The Roof

    If the site runs light at midday, the extra kilowatts are exported, not saved.

    See the matrix
  4. 04

    No Battery Case

    It should be a comparison, not an upsell or an omission. Sometimes it clearly does not pay.

    See the battery
  5. 05

    Incentives Blurred In

    Before or after certificates? What site works? Both should be itemised.

Questions

Straight Answers

Something else? hello@amperage.app

How long does a job take?

About 10 minutes from the customer's bill to a credible estimate in Analysis. A full Proposal takes longer, depending on how much roof, tariff and pricing detail you add.

Is the modelling hourly?

Yes. Solar production and battery dispatch are simulated for every hour of a typical weather year from the nearest BoM climate file, against the site's own load and its network tariff, including demand charges.

Which incentive schemes are included?

STCs (including battery STCs under Cheaper Home Batteries), LGCs, VEECs and the NSW PDRS. Each one shows the rule it applied and the certificate price it used.

Can I put my own branding on the outputs?

Yes, on Pro. Your logo, colours and contact details go on the PowerPoint deck, the A4 PowerPoint proposal and the customer web link, from a brand profile in Settings.

What happens to my customer's data?

Bills and interval data are stored against the project, inside your company's account, and are visible to your team and to the people you share the project with. Bill PDFs are read by Anthropic's Claude API, which does not use API inputs for model training.

Does it replace my panel layout tool?

No. Amperage models roof faces (their tilt, direction and capacity), not individual panel placement. Keep your layout tool for the panel plan.
