About Teranautics

Who the site serves

The site is for homeowners and other readers trying to understand heat-pump and residential-solar costs, running expenses, savings, and payback. The available calculators currently use US defaults; those defaults are unverified illustrative values, not published market averages. The heat-pump calculator page shows which regional tools are available.

Why energy estimates are hard to compare

A quoted installation cost is only one part of a decision. Results also depend on a home's characteristics, equipment and installation requirements, local energy prices, usage patterns, incentives, financing, and the period being compared. Two estimates can use different assumptions and still look like they describe the same thing.

Teranautics' tools make a limited set of those inputs visible. They let readers change values and explore how assumptions affect an estimate; they do not determine a system's precise suitability or performance for a particular home.

How the calculators and guides help

The US heat-pump calculator compares simplified installation and operating-cost scenarios. The solar calculator estimates generation, bill effects, and costs from the inputs shown on the page. Educational guides explain concepts that affect those calculations.

Every calculator output is an estimate based on the values supplied by the reader and the assumptions shown beside the result. A range is a sensitivity range, not a probability forecast or a guarantee. Results are not installation quotes, professional site assessments, or individualized financial advice.

Sources, formulas, and uncertainty

Transparent formulas make it possible to inspect what the tools calculate. The methodology documents the implemented equations and their limits; the data-sources register distinguishes sourced values from placeholders. Unverified defaults should be replaced with figures from a reader's own bills, quotes, and utility terms before relying on an estimate.

Source quality matters because a formula cannot make weak or illustrative inputs into reliable facts. Teranautics aims to identify uncertainty rather than present a single result as universally applicable. The editorial policy explains the site's sourcing and correction standards.
