K2 Docu is a free Android app developed by K2 Systems GmbH, designed to streamline and simplify the documentation process for photovoltaic projects. With this app, installers can save time and manage all the relevant data of their PV systems in one central place.

The app allows users to document various aspects of the PV system, including circuit diagrams, module data sheets, and mounting plans. All project documents are structured and clearly laid out, making it easy to access and manage them while on the go, at the construction site, or in the office.

One of the standout features of K2 Docu is its seamless integration with the K2 Base planning software from K2 Systems. If users are already using K2 Systems' assembly systems, they can easily sync the app with the planning software to access documents such as structural analysis reports, assembly plans, and data sheets. Even if users install a different assembly system manufacturer, they can still upload relevant documents to the app.

After completing a project, users can have their customers sign the documentation directly in the app. The app then allows users to send the documentation digitally and on-site as a PDF file, providing a simple, fast, and clever solution.

K2 Docu also offers additional features such as a project overview, employee management, and the ability to upload documents from different manufacturers. With its user-friendly interface and comprehensive functionality, K2 Docu is a valuable tool for installers looking to streamline their documentation process for photovoltaic projects.
