What they did
A German solar installer with 1,000+ installs runs local models on his own hardware. He gave his Hermes agent a roof overnight. It pulled the 3D geometry, planned 9.30 kWp and 11.62 kWp layouts with a string voltage check, and fit 20 panels, 3 more than his own manual draft of 17.

Prompt
Cleaned version rewritten from the source — not a direct quote.
Here's the address and roof data for a solar job: [address, roof photos or 3D model, panel model, inverter]. Plan two panel layouts at different sizes, list the panel count and kWp for each, and check string voltages against the inverter limits. Show the layout drawings and every assumption so I can check them before quoting.
Recommended
Try it in Grok Bot
Grok Bot can draft a first layout from roof photos and the panel specs, but have a qualified installer sign off.
- Copy the prompt (button below).
- Open Grok Bot chat and paste it. Replace any [bracketed] placeholders.
- Connect the listed tools (as needed) as connectors when Grok Bot asks.
- If the task repeats, ask: "Make this a daily routine."
Alternatives: the same prompt works in Hermes Agent, Claude, ChatGPT Agent, OpenClaw.
Set it up
Stack: Hermes Agent
- Read the original source for full context.
- Connect the tools your agent needs.
- Paste the prompt and replace [bracketed] placeholders.
- Run once manually and check the output before scheduling it.
