Arcadia
Weather, tariff & utility data · Web
The US electricity tariff database and rate-calculation engine that sits underneath other companies' solar savings numbers — now sold by Arcadia under the name Signal, with the Genability brand retired from all public marketing but still live in the API hostname.
Meteotest AG
Weather, tariff & utility data · Web
The Swiss climate database that generates a typical meteorological year for any point on earth — the TMY file that PVsyst, PV*SOL, Polysun and SAM all import — now rebuilt as a web application plus four REST APIs (Climate, Observation, Forecast, Horizon).
Clean Power Research, L.L.C.
Weather, tariff & utility data · Web
Clean Power Research's satellite-derived solar resource dataset — historical back to 1998, real-time, and forecast — built on the Perez/SUNY Albany irradiance model, sold as web access and an API, with free PV power modelling (PVWatts and pvlib) bundled into every licence.
Solcast
Weather, tariff & utility data · Web
A global satellite-derived solar irradiance, weather and PV-power API — historic back to 2007, live to the last five minutes, and forecast to +14 days — delivered as data, not as an application.
UtilityAPI
Weather, tariff & utility data · Web
The customer-authorisation and utility-data-collection layer: it gets a US electricity customer's permission, connects to their utility account, and delivers their meter details, their actual bills and their 15-minute interval usage to whoever they authorised — over a fully documented public API with a fully published price list.

Not published — and the gate is stated openly
A “best” page requires five scored products, each carrying eight verified reviews.
Blocking gate on record: G-data (no scored products until reviews land)
When the gate clears, the page will publish with its methodology above the list — and the publisher’s own products will still be excluded from it. How ranking works
We research 5 products whose primary category is Weather, tariff & utility data.
2 of 5 publish a price outright and 0 publish some tiers. The rest are quote-only or do not disclose pricing at all.
Not yet. A ranking requires five scored products, and a score requires eight verified reviews per product. No product is scored today, so this page presents evidence rather than an order.
