Απόδοση Ηλιακής Ενέργειας ανά κτίριο - “Solar Map”Solar Energy Yield per Building - "Solar Map"
This API provides access to a solar energy yield map for building rooftops in Athens, developed under the city's 2017 Climate Action Plan, which aims to promote the installation of solar photovoltaic (PV) systems on private buildings throughout Athens. The map is intended as a tool for citizens to assess the potential solar energy performance of their rooftops, supporting informed decisions about installing PV systems. It is published by the City of Athens and covers the municipal area at a building level, offering national-scope geographic data for Greece under free, unauthenticated access.Σύμφωνα με το εγκεκριμένο το 2017 Σχέδιο Δράσης για το Κλίμα, στόχος είναι η προώθηση ηλιακών φωτοβολταϊκών (PV) σε ιδιωτικά κτίρια σε όλη την Αθήνα.Ο χάρτη απόδοσης ηλιακής ενέργειας για τις στέγες των κτηρίων της Αθήνας θα αποτελούσε χρήσιμο εργαλείο για τους πολίτες, ώστε να εξετάσουν την αποδ...
