I mean really if they are going to drop their insistence on solar panel installations as part of a retrofit then why keep the name? Are they now a software company or are they now a software and then install whatever company? Good questions with no answers. It would be like Tide if it were to stop making soap and started making dishwashers. Would they keep the name and why?
Has SolarCity Created the Amazon 1-Click for Energy Efficiency?
“We believe SolarCity has the best database of residential energy use of anyone in the world.”
Stephen Lacey: June 28, 2013
After SolarCity shifted its energy efficiency strategy and pulled back from doing residential retrofits in-house, the solar services behemoth is moving straight into intelligent efficiency.
GTM’s Eric Wesoff recently reported on SolarCity’s evolving business plan and the resulting changes that company executives say will scale residential efficiency in the same way solar services have scaled residential solar.
But solar is very different from efficiency. For the most part, solar is very standardized and installations are uniform from home to home. Efficiency retrofits encompass an extraordinarily broad category of activities and skills. Incentives are also quite different for efficiency, making it more complicated from a financial perspective. That’s why only a handful of U.S. solar contractors have offered efficiency as an in-house service.
SolarCity decided that doing the retrofit work itself was not the best way to scale. Instead, it has turned from manpower to the power of big data.
The secret sauce is a “simulation engine” that shows homeowners exactly how much they’re spending on energy everywhere in their house. The initial database was created using information from 16,000 home energy audits performed over the last five years. It relies on an algorithm developed at the Department of Energy that crunches 100 million calculations per home for each individual energy efficiency audit (which is still performed by SolarCity when installing solar).
“The simulation software looks at every component in a home in relation to one another,” said SolarCity COO Peter Rive. “Every ten minutes, it thinks about what one thing is doing and about its effect on the rest of the systems within the home.”
