Founded by Joe Schellenberg in 2018, SolarStamp.io (an ENGletter Company) was built to solve the inefficiencies between solar companies, engineers, surveyors, and designers. What started as a simple way to streamline surveys and engineer letters has grown into a complete web app. In 2024, we expanded to include city permits and solar panel removal & reinstallation (R&R), making SolarStamp.io the all-in-one solution for faster, more profitable solar projects.
