How to Assess Solar Viability with ChatGPT
Assess solar panel viability with ChatGPT and ToolRouter. Financial estimates for solar installations.
Tool
ChatGPT combines solar generation estimates with financial analysis to produce clear investment appraisals, comparison tables for different system sizes, and written summaries that help homeowners make confident decisions. It is well suited to producing shareable reports that non-technical stakeholders can understand.

Steps
Once connected (see setup above), use the Energy Data tool:
- Ask: "Estimate solar generation for a 3.5kWp system at postcode EX1 1JZ facing south using energy-data"
- ChatGPT returns generation estimates by month
- Request: "Write a one-page solar investment summary including estimated ROI"
- Follow up: "How does this compare to the UK average for this region?"
Example Prompt
Try this with ChatGPT using the Energy Data tool
Generate a solar feasibility report for a 4kWp south-facing system at postcode GL1 2EL. Include monthly generation, annual savings at 28p/kWh, and a simple payback calculation.
Tips
- Request estimates for two or three system sizes to help decide on the right capacity
- Ask ChatGPT to factor in any known shading (nearby trees, buildings) and explain the impact
- Use this before meeting an installer so you can verify their quote against independent data
