Welcome to opensource-solar.org, a place for collaborative development of open source hardware for small photovoltaic systems.

Photovoltaic power supplies are very useful if grid electricity is unavailable, cabling inconvenient, or in emergency situations. We provide a modular system consisting of a Solar panel, microcontroller based Charge controller, and application specific modules for LED lighting and cell-phone charging with a DC-DC converter.

Our goal is to build systems of highest quality affordable for everyone.

This is possible by DIY assembly and open source community designed kits which will be shipped worldwide. One of the biggest advantages of our open source design method is that it gives unparalleled opportunities for learning about photovoltaics. We use, wherever possible, Open source Software for this work. Only a small set of Tools and some simple skills like soldering are required for assembly and for taking part in the design efforts.
