# How to Optimize Solar Energy with ChatGPT

ChatGPT turns sunrise and sunset data into practical planning advice that goes beyond simple time lookups. It helps you build event timelines around golden hour, understand how seasonal daylight changes will affect travel to unfamiliar destinations, and schedule outdoor activities when the light will be at its best. ChatGPT explains the quality of light at different twilight phases, recommends the ideal time to arrive at a viewpoint, and builds complete itineraries around the natural rhythm of the sun.

## Setup

{"mcpServers":{"toolrouter":{"command":"npx","args":["-y","toolrouter-mcp"]}}}

## Steps

1. Configure ToolRouter in ChatGPT
2. Ask: "Calculate sun hours for my location across different seasons"
3. ChatGPT returns daylight data with analysis
4. Request: "Estimate solar production potential from these numbers"

## Example Prompt

```
How many sun hours does Munich get each month? I want to understand the seasonal swing for solar panels.
```

## Tips

- ChatGPT can explain how day length impacts solar ROI at your latitude
- Compare your location with solar-optimal areas for context
- Ask about solar noon timing for panel orientation
