New data are added all the time, but we don't have a specific refresh rate
for specific regions. Some regions use imagery that is several years old.

Where can I learn more about the assumptions for the solar financial analysis?
Google uses information about government solar incentives, along
with other financial data and models, from Clean Power
Are chimneys and skylights taken into consideration by the API when making an assessment of solar panel placement?
Yes, with height maps chimneys and skylights are identified as small
rectangles, and solar panels are excluded by the model.
Can the API see inside of buildings?
No, just the roofs.
Can the API make assessments for a specific apartment within a building complex?
Depends. The model uses Google Maps data, and so if the apartment is
classified as a whole building in Google Maps, then the roof of a specific
apartment of that building are displayed as separate.
Why does the API sometimes not return any data for a building which I know exists?
This can happen when there are newer buildings that did not exist when
mapping was realized at the time.
How can I use the flux solar data layer for visualizing shade?
North-facing roofs get less flux (solar
irradiance), which means
they will have higher shade. You can leverage this information when
performing solar assessments. The flux data layer lets you visualize
flux in colors.
You can alternatively make your own flux tiles and customize their colors,
especially if you wish to locate specific numerical values of shade on a
