New Online Market Simplifies Going Solar with Free, Instant Appraisal of your Sunlight's Value

Geostellar Expands Service to Look Up Your Potential Savings, Energy, and Environmental Benefits then Connect with Leading Solar Installers

Martinsburg, W. Va. Geostellar, the award winning startup that simplifies going solar, rolled out its groundbreaking online marketplace today in areas across the Mid-Atlantic, New England and West Coast. The platform gives people an instant, free and 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 smartest way to go solar.

"Geostellar makes the process of going solar as safe, available and affordable as booking travel, watching videos or socializing with friends online," said Geostellar CEO David Levine. "Our installation and financing partners are best of breed, and committed to delivering the most value to the homeowner through their solar energy systems."

"Real Goods Solar is pleased to be working with Geostellar on the launch of its innovative platform," said Kam Mofid, CEO of Real Goods Solar. "As one of the nation's leading solar companies with years of commitment to 100% clean renewable energy, we look forward to this partnership to help new customers realize the wonderful economic and environmental benefits of going solar."

"Reaching the right homeowners who can most benefit from switching to solar energy is a big challenge for our industry," said Astrum Solar President and Chief Executive Officer Vadim Polikov. "Geostellar helps close this opportunity gap by offering an elegant way to connect us with a well informed public."

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.
