You have an indication. Here is what it cannot do yet.

The number you saw is genuinely computed and deliberately cautious. It answers whether the direction pays off. It does not answer what you should build — that needs your load profile, your grid connection and your prices.

The three steps

Indication · You already have this

A conservative first answer from annual consumption and region: does it pay off, in what basic shape, how fast. Closed-form, in seconds, free and freely citable.

Analysis · The next step

Your real load profile instead of one number. Computed quarter-hour by quarter-hour with your prices, your grid connection and your roof — and every architecture compared, not just one.

Bankable report · When money moves

The version a bank reviews: ranges instead of a point estimate, battery ageing, grid fees and balancing markets, debt service coverage — and a document that traces every figure back to its decision node.

What the analysis does differently

Your measured load profile instead of an annual figure
Quarter-hourly operation across the full lifetime, not a rule of thumb
Grid fees, balancing markets and your actual connection
Battery ageing over the years
Ranges (p10 / p50 / p90) instead of a single number
Every figure traceable to its decision node — reproducibly verifiable

The indication stays free and freely citable. It is not a bankable result and must not be used as a design basis.
