How to Model Energy Costs and Solar Savings with Claude
Model home energy costs and solar savings with Claude and ToolRouter. Combine live prices with generation estimates.
Tool
Claude works across both datasets simultaneously — taking your current electricity pricing, your solar generation estimate, and your typical consumption pattern to model total annual costs under different scenarios. It reasons through the trade-offs and recommends the approach with the best financial outcome for your specific situation.

Steps
Once connected (see setup above), use the Energy Data tool:
- Ask: "Get electricity prices for London for today using energy-data"
- Then: "Estimate solar generation for a 4kWp south-facing system at postcode E1 6RF using energy-data"
- Ask: "I use 4,000 kWh per year. Model my annual costs with and without solar"
- Request: "What would adding a battery change about this picture?"
Example Prompt
Try this with Claude using the Energy Data tool
Get today's electricity prices for London and estimate solar generation for a 4kWp south-facing system at E1 6RF. I use 4,500 kWh per year. Model my annual electricity costs with solar only, and with solar plus a 10kWh battery, against my current spend.
Tips
- Provide your actual annual consumption figure for accurate modelling — check your last bill
- Ask Claude to split the analysis into summer and winter to understand seasonal variation
- Request sensitivity analysis: "what if electricity prices rise by 20% next year?"
