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?

Steps

Once connected (see setup above), use the Energy Data tool:

  1. Ask: "Estimate solar generation for a 4kWp south-facing system at postcode BS1 5TL using energy-data"
  2. Claude returns monthly and annual generation estimates
  3. Ask: "How much could I save annually at current electricity prices?"
  4. Request: "What's the approximate payback period if installation costs £8,000?"

Example Prompt

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

  • 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
