Estimate Solar Energy Generation for Any Location
Calculate how much electricity a solar installation would generate at any UK location based on irradiance and panel configuration.
Quick answer: Use the Energy Data tool through ToolRouter to estimate solar energy generation for any location directly from Claude, ChatGPT, Microsoft Copilot, and OpenClaw — connect once, then drive it with plain-language prompts. No code required.
ToolDeciding whether to install solar panels means answering a question nobody around you can answer precisely: how much electricity will these panels actually generate here, at my specific address, facing my specific roof? Installer quotes vary wildly, and the estimates on most comparison websites are based on regional averages that ignore local shading, pitch, and orientation.
The solar_estimate skill calculates expected annual and monthly generation for a given location, panel capacity, and orientation. It uses actual solar irradiance data for the coordinates rather than regional approximations, giving you a figure you can trust when comparing against your current electricity bill or evaluating installer proposals.
Homeowners assessing solar viability, property developers planning new builds with solar, and energy consultants validating installer quotes all use this to get honest, location-specific generation estimates before committing to an installation.
How to estimate solar energy generation for any location with Claude, ChatGPT, Microsoft Copilot, and OpenClaw
Claude takes a solar generation estimate and turns it into a full financial picture — calculating payback periods, annual savings against current tariffs, and how much excess generation you could export. It answers the real question behind every solar enquiry: is this worth the money for my specific situation?

How to estimate solar energy generation for any location with Claude
Once connected (see setup above), use the Energy Data tool:
- Ask: "Estimate solar generation for a 4kWp south-facing system at postcode BS1 5TL using energy-data"
- Claude returns monthly and annual generation estimates
- Ask: "How much could I save annually at current electricity prices?"
- Request: "What's the approximate payback period if installation costs £8,000?"
Example prompt for Claude
Try this with Claude using the Energy Data tool
Estimate annual solar generation for a 5kWp system on a south-facing roof at postcode TQ4 6AF. Calculate my likely annual savings and payback period assuming I pay 28p per kWh and the system costs £9,500 installed.
Tips for Claude
- Try different panel orientations (south-east, south-west) to see how much tilt matters for your roof
- Ask Claude to compare generation estimates with and without battery storage
- Request a month-by-month generation profile to understand winter shortfalls
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.

How to estimate solar energy generation for any location with ChatGPT
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 for ChatGPT
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 for ChatGPT
- 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
Copilot makes solar generation data available in your IDE for building property energy calculators, solar comparison tools, and sustainability reporting features. The structured output gives you monthly generation arrays ready for chart components and financial modelling functions.

How to estimate solar energy generation for any location with Copilot
Once connected (see setup above), use the Energy Data tool:
- In Copilot Chat: "Estimate solar generation for a 4kWp south-facing system at postcode SW1A 1AA using energy-data"
- Copilot returns structured monthly generation data
- Ask: "Write a function that calculates annual savings from this generation profile"
- Request: "Generate a TypeScript interface for the solar estimate response"
Example prompt for Copilot
Try this with Copilot using the Energy Data tool
Get solar generation estimates for a 5kWp system at postcode M1 2AN and return as JSON with monthly kWh values and an annual total.
Tips for Copilot
- Build a savings calculator function that accepts a tariff rate and generation profile
- Cache estimates by postcode and capacity — irradiance data changes slowly
- Combine with electricity price data to calculate real-time savings based on current tariffs
OpenClaw processes solar generation estimates for multiple addresses in a single operation, making it suitable for property developers assessing solar across an entire new-build estate, energy consultancies running portfolio-wide audits, or research projects needing generation data at scale.
