Solar Panel Energy Estimate by Location (PVGIS, Bulk)

Estimate monthly solar photovoltaic energy production (kWh) and irradiation for any latitude/longitude using the European Commission PVGIS model. Set panel peak power, system loss, tilt and orientation. Bulk locations, one row per month. No key needed.

What does Solar Panel Energy Estimate by Location (PVGIS, Bulk) do?

Monthly solar PV energy output estimates for any location from the EU PVGIS model.

What can you use it for?

• Size rooftop solar systems for many sites.
• Compare yields between candidate locations.
• Build solar calculators and lead-gen tools.
• Check seasonal production for energy planning.

Why use this Actor?

• Fast and cheap: lightweight HTTP-based Actor with no browser, so runs finish in seconds and cost very little.
• No API keys or accounts needed for the data source (see notes below).
• Clean, structured JSON that you can export as CSV, Excel, JSON or XML, or pull through the Apify API and integrations.
• Scheduling, webhooks and integrations: run it daily and send results to Google Sheets, Slack, Zapier, Make, n8n or your own API.

Input

How much does it cost?

The Actor is billed by Apify according to the pricing shown on the Pricing tab of this page. Runs are small and fast, and the Apify Free plan includes monthly platform credits so you can try it at no cost. You can set a maximum cost per run, and the Actor stops cleanly when that limit is reached.

Notes and limitations

• Coordinates as 'lat,lon'. Covers Europe, Africa, most of Asia and the Americas. Source: European Commission JRC PVGIS. Estimates, not guarantees.

Tips

• Start with a small test run, then scale up the input.
• Use Schedules to automate recurring runs and Webhooks or Integrations to deliver the data where you need it.
• Call the Actor from your code with the Apify API or the official JavaScript and Python clients.

FAQ

What does angle 0 mean?

Tilt 0 = flat panels; 90 = vertical. Leave tilt empty to use the optimum angle.
