Our mission

Accelerate solar adoption through efficient operations

SolarStream's vision is to lead Switzerland towards a sustainable, solar-powered future. We recognize the challenges and hurdles that Swiss solar companies face every day in managing solar projects and are committed to developing a solution that not only meets the unique needs of the local market, but is also secure, efficient and user-friendly.

Our goal is to offer Swiss solar companies a software that directly integrates as many existing solutions in the market as possible to simplify project and document management, improve communication and protect your data according to Swiss security standards. By working closely with our customers, we understand their needs first-hand and continuously develop our solution to meet them. At SolarStream, we are not just a software provider, but a committed partner actively promoting Swiss solar energy with the clear goal of making a green future a reality, project by project.
