independent appraisal of the value of the sunlight that shines on each and
every roof.

For the first time, people can access all the information, goods, services and
support they need to make the best possible decision on a solar energy system.
Leading solar installers, financers and equipment companies are all
represented on the platform, making Geostellar the safest, easiest, and

Geostellar’s advanced 3D geo-mapping models sunlight down to the square meter
- taking into account the slope and orientation of the roof and shadows from
trees and nearby buildings - over the course of a full year to determine the
energy-production potential of every property. Geostellar applies that data to
determine the economic benefits of solar for each property based on system
costs, electricity rates, incentives and usage patterns.

“Geostellar gave us a solar analysis on our home showing us the best, most
productive placement for modules, estimated productivity, costs and tax
incentives as well as a referral to a local solar contractor,” said Debbie
Royalty of Charles Town, WV, who looked up her home on Geostellar and
contracted with Bill Anderson of Milestone Solar. “This was what we needed to
move forward.”

Geostellar’s innovative service has already earned several awards including
selection for the Global Cleantech 100 and the GCCA’s 2012 Later Stage Award
Best of Solar.
