Use Case — Solar Project Developers
From site address to go/no-go package in under two seconds.
Solar project developers use Derapi to automate the data-intensive front end of project development — interconnect queue screening, AHJ permit requirements, and GHI irradiance assessment — all returned in a single JSON response. Query by ZIP, lat/lon, or FERC zone.

The Problem
Solar site screening still runs on spreadsheets and portal scraping
Without Derapi
- Log into each utility's interconnect portal individually
- Manually copy queue position and capacity data into a spreadsheet
- Search AHJ county websites for permit requirements, often out of date
- Run NREL's PVWatts manually per site for irradiance estimates
- Each site screening takes 2–3 hours of engineering time
With Derapi
- Single API call returns interconnect data, AHJ requirements, and irradiance
- Unified JSON schema — same response structure across 300+ utilities
- AHJ permit data maintained by Derapi across 2,400+ jurisdictions
- 7-day irradiance forecast + actuals in the same response
- Site screening time under 2 seconds, scalable to thousands per day

Before Derapi, we were screen-scraping PGE's interconnect portal and manually entering AHJ requirements into spreadsheets. Now our site screening tool queries Derapi and returns a full go/no-go package in under two seconds. We screen 10x more sites per day now.
