The new Google Solar API calculates the potential and ROI of photovoltaics right on your roof

20. 11. 2023 | Natalie Bezděková

The Google Solar API brings a revolutionary solution for obtaining information about solar energy and calculating the return on investment of photovoltaic panels directly on the roof of the house. The service uses artificial intelligence and combines accurate roof data with meteorological information to predict the potential energy production from PV panels. The model takes into account various factors such as roof pitch and shadows from nearby trees.

Google allows companies specializing in photovoltaics to integrate the Solar API into their web applications, simplifying ROI estimates and energy production predictions. This innovative service has the potential to simplify the decision-making process for homeowners and make solar energy more accessible to a wider range of users.

The API currently contains information on 320 million buildings in 40 countries, with plans to expand it further in the future. The aim of the project is to provide solar installers with an overview of a site’s potential and installation costs before physically visiting the site, which will help to inform homeowners more quickly and efficiently about solar energy options.
