pp-pvgis
The free, single-binary PVGIS CLI — JRC solar-radiation and PV-yield estimates with offline cache, multi-site... Trigger phrases: `estimate solar production at`, `what's the optimal tilt for`, `get TMY weather for`, `PVGIS yield`, `use pvgis`.
Why this skill is useful
Adds executable commands for solar yield estimation and analysis that are not available in public documentation.
What it needs
Requires pvgis-pp-cli installed locally. About 7k tokens when loaded. Last updated 2026-08-06. 1,890 stars on the source repository.
What this skill does
PVGIS — Printing Press CLI Prerequisites: Install the CLI This skill drives the pvgis-pp-cli binary. You must verify the CLI is installed before invoking any command from this skill. If it is missing, install it first: 1. Install via the Printing Press installer. It defaults binaries to $HOME/.local/bin on macOS/Linux and %LOCALAPPDATA%\Programs\PrintingPress\bin on Windows: 2. Verify: pvgis-pp-cli --version 3. Ensure the reported install directory is on $PATH for the agent/runtime that will invoke this skill. If the npx install fails (no Node, offline, etc.), fall back to a direct Go install (requires Go 1.26.6 or newer): If --version reports "command not found" after install, the runtime cannot see the binary directory on $PATH. Do not proceed with skill commands until verification succeeds. When to Use This CLI Reach for pvgis-pp-cli when an agent or pipeline needs ground-truth solar-yield estimates from the JRC PVGIS service without subscribing to commercial APIs. Best when the workflow involves multiple candidate sites, repeated parameter sweeps, or downstream consumers (PVSyst, SAM, custom models) that want clean JSON or CSV. When Not to Use This CLI Do not activate this CLI for requests that require creating, updating, deleting, publishing, commenting, upvoting, inviting, ordering, sending messages, booking, purchasing, or changing remote state. This printed CLI exposes read-only commands for inspection, export, sync, and analysis. Unique Capabilities These capabilities aren't available in any other tool for this API. Local state that compounds sites rank — Rank a CSV of candidate sites by annual yield/kWp under the same system spec. Use when an agent has a list of candidate roofs/sites and needs to recommend the highest-yield one without N round trips. production sweep — Compute a 2D grid of yields across tilt and azimuth, cache it, and serve future point queries from local interpolation. …
