Monthly Solar Radiation at a Location (PVGIS)

pvgis/monthly-radiation

Monthly solar radiation for a latitude and longitude from the PVGIS satellite and reanalysis databases (2005 to 2023): horizontal-plane irradiation H(h)_m, irradiation on the optimally inclined plane H(i_opt)_m and direct normal irradiation Hb(n)_m, in kWh per square metre per month, one row per month of each requested year. Covers Europe, Africa, most of Asia and the Americas; points over open sea are refused. Estimates calculated by PVGIS (European Commission Joint Research Centre), served by Eden Engine; not an official European Commission product.

// 1. search: find the tool
omnial_search({ query: "what you need" })

// 2. inspect: price and input schema
omnial_inspect({ tool: "pvgis/monthly-radiation" })

// 3. learn: read the usage guide at runtime
omnial_learn({ tool: "pvgis/monthly-radiation" })

// 4. run: price the exact call first, then run it
