One of the significant costs of residential solar power is for permitting. While the permitting fee itself is significant, the amount of time and effort to get a permit approved is expensive. Each municipality has their own rules, procedures and hoops to jump through. And the influx of summer permits into a municipality overwhelms their staff causing delays. Then with the inevitable question/answers going back and forth, the total process could be a week or months.
The other factor in the delay is consumer anxiety. The property owner was expecting a permit to be get approved within a week and after a month, they become worried there's a problem. This means the sales staff needs to regularly communicate to the owner to reassure them - spending time reassuring a sale rather than going out making new sales. And then if the process takes too long, the owner cancels the order. All the initial sales effort, design effort, effort working with municipalities and reassuring the owner is lost (and these costs need to be absorbed by a new sales).
Why has this been a problem? Each municipality works independently, different areas have dramatically different requirements (eg southern California beach house, Colorado chalet, Minnesota home, 200 year old Massachusetts colonial).
Then there was the Solar Foundation and Spark Ranch.
The Solar Foundation were a group of industry experts from various organizations - NREL (National Renewable Energy Laboratory), Tesla, Sunrun, SEIA (Solar Energy Industries Association), etc. These experts were able to determine the vision of what a common permit should include and areas where flexibility needed to be available for municipality specific requirements. Then the good fortune, DOE (Department of Energy) offered a grant program to offer 50% of the seed money to build applications that would then be commercialized. But they heard such a robust, flexible application could not be built.
Enter Spark Ranch. Jim Vezina of Spark Ranch worked with them to understand their vision and architected a solution that was not only robust and flexible enough to satisfy their needs, but could then be used to support related needs like batteries and heat pumps. He laid out the plan to quickly deliver a prototype leveraging existing Spark Ranch technology and then the phases for rollout.
Jim Vezina continued as part of the team to develop the application until it could be transitioned to a new company SolarAPP+.
The application is significantly reducing permitting time and overall project costs. For example, one company will redesign a customer solution in order to get immediate approval from SolarAPP+ rather than going through the normal manual process with the municaplity.
