Solar yield, irradiation and system sizing - no API key.

Tools

• pv_yield — Monthly and yearly solar output for a location. Give kWp and tilt, or leave tilt out to use the optimal angle.
• radiation — How much sun a site gets, month by month, on a tilted panel plane - with the year-to-year spread.
• hourly_output — Hour-by-hour solar data for one year, summarised by month: average irradiance, sun hours and temperature.
• typical_weather — The typical meteorological year for a site: monthly temperature, humidity, wind speed and global irradiation.
• system_summary — Plain-language verdict for a PV system: yearly output, yield per kWp, capacity factor, CO2 avoided and roof area.
• compare_locations — Compare up to 5 sites for the same system size and name the best one, e.g. '45,8; 52.5,13.4'.
• size_system — Work out the system size needed to cover a target annual consumption at a location, with panel count and roof area.
• horizon_profile — What the terrain blocks at a location: obstacle height every 7.5 degrees of azimuth, the steepest obstacle and how much of the southern arc is obstructed.
• offgrid_sizing — Simulate an off-grid array and battery against a real daily load: how often the load is not met, energy thrown away and the month-by-month shortfall.
• optimal_tilt — The tilt and azimuth PVGIS calls optimal here, and what a flat 30 degree south mount costs in kWh per kWp per year against it.

Setup

No setup. Solar data comes from the public PVGIS API of the EU Joint Research Centre.

Premium tools

These tools need a license key:

• solar_variability
• diurnal_profile

Buy a key at https://mcp-marketplace.io/server/io-github-mrfentmen-pvgis-mcp and set it in your MCP client config:

"env": { "MCP_LICENSE_KEY": "mcp_live_..." }

The key is checked against MCP Marketplace, cached for 24 hours, and keeps working offline once one check has succeeded. Every other tool on this server stays free.
