When homeowners are interested enough to get bids, it collects estimates from a large pool of installers and provides a detailed comparison of the proposals. According to Levine, part of the difficulty in assessing a homeowner’s options is the lack of standardized vendor processes and the variance around Solar Renewable Energy Credits.
Some vendors, for example, could have a pricing advantage because its models are based on a different set of assumptions than its competitor: The lower-priced proposal might assume utility rates would rise an average of 7 percent over the 25-year life of the panel, while the other vendor, with worse savings, only assumed a 4 percent rate increase.
By functioning as the broker, Geostellar meshes all the rates and best practices from vendors and delivers an “apple-to-apples” comparison, as Levine describes it.
That helps both parties. Confusion is removed from the bidding process and installers can focus on scaling installation, instead of spending on soft costs associated with things like marketing and customer churn.
In a March research brief, financial services firm Raymond James Financial cited data from the Rocky Mountain Institute that estimated soft costs represent more than 60 percent of total U.S. system costs, and are roughly four times higher than in Germany, despite higher labor prices. That’s a key metric because Geostellar charges installers a transaction fee, one it says is less than a solar installer’s cost to acquire a customer.
“With solar, now that the technology is proven, the industry’s biggest challenge is driving down costs," Raj Prabhu, managing partner at Mercom Capital Group in Austin, Texas, said in a recent Bloomberg article. "The new money is going downstream to help build markets. The industry is now mainstream.”
