What can be done?
You can retrieve building-level solar information and data layers for analysis. The results do not guarantee installation feasibility and are handled on the premise of being combined with other verifications such as on-site surveys, structures, regulations, and power conditions.
General users and administrative staffuse the estimation and candidate comparison screen,IT administratorshandle Projects, billing, API keys, and data usage terms, anddevelopershandle location specification, responses, and rendering methods.
Bridge for Microsoft experienced professionals
It is not a simple equivalent of Microsoft's map products. Its role is easier to understand if you view it as "specialized environmental data APIs provided by Google in addition to the mapping infrastructure."
Testing safely
Use a supported public location in the official sample and set receiving building information as the success criterion. Change only a single location to check support status and result differences. Do not store API keys or customer addresses in public GitHub repositories.
Google Official Information
Article-specific re-evaluation
The Solar API handles Building Insights, Data Layers, and other features that evaluate solar potential on a building-by-building basis. Data such as roof shape and solar radiation can be used for design studies, but it does not guarantee installation feasibility or final power generation output.
Papanda TRY
Make it a Daily Code that visualizes the flow of 'solar radiation -> panel candidates -> estimation' using SVG/HTML with fictional roof data. Do not use real addresses or residential information in public fixtures.
What kind of service is this, ultimately?
An API that provides geographical and insolation data to apps for evaluating the solar power generation potential of buildings. It is used as material for candidate evaluation, and the final decision is made in conjunction with site conditions and other factors.
