{{DISPLAYTITLE:Main Page}}<languages /> <strong>Welcome to the Open Source Solar Project</strong> The mission of Open Source Solar Project is to share information in various langauges about the design and installation of off-grid photovoltaic (PV) systems to lead to better performing, safer systems in the developing world. Please reach out to alex@opensourcesolar.org if you are interested in collaborating, have found mistakes, would like to contribute or need assistance creating training materials. Be advised that design, installation, and maintenance work should only be performed by qualified individuals in accordance with local codes and laws. There is no guarantee that the information provided on this website is accurate or complete - use it at your own risk. It is intended to serve as an educational and reference resource - appropriate hands on training is required in order to safely work with electricity and PV systems. See [[Special:MyLanguage/Training providers|Training providers]] for a list of recommended training providers.
