Which might suit you

Framed as requirements, not a verdict. Both descriptions come from the same data.

Consider Solcast if…

  • you need it to connect to tools you already run (5 named)
  • you work at utility scale
  • your work is mostly residential

It is for whoever is *building* the thing an installer uses: a design tool, a monitoring platform, a trading desk, a grid operator, a resource analyst automating yield studies. It is not a tool a solar installer sits in front of. There is no drawing canvas, no proposal, no customer-facing output. If you are comparing Solcast against a design tool, you have made a category error.

Consider UtilityAPI if…

  • you need a price you can plan against before talking to sales
  • you work at utility scale
  • your work is mostly residential

It is for whoever needs a specific customer's *real* consumption with that customer's consent — a proposal tool sizing a system, a financier underwriting a PPA, a storage developer modelling demand charges, a programme administrator qualifying a rebate. It is not a tariff engine, not a rate calculator, and not a solar tool. It will tell you exactly what a customer used and was billed; it will not tell you what a different rate would have cost them.
