About
About WattNumbers
Free home-energy calculators for the browser, made by one maker.
What it will do
WattNumbers is being built as a site of free home-energy calculators that run in the browser: solar PV yield, balcony solar, dew point, U-value, a heat-load estimate and feed-in tariffs. Each result shows its inputs, method and sources. German pages come first (/de/), then the Netherlands, the United Kingdom and the United States.
No calculator is live yet. The site opened early so that search engines can find it while the calculators are built.
