Opensource-solar.org is working on open hardware power supplies for off-grid applications. The systems consist of self-build solar panels, charge controllers with microcontroller, and LiFePo4 rechargeable batteries. Green energy for your gadgets ! A photovoltaic based power supply for small devices is especially useful if an electricity grid is unavailable, if cabling is inconvenient, and in emergency situations. Opensource-solar.org designs modular open hardware photovoltaic power systems which can be incorporated in other projects. The focus is on micro-energy systems with less then 16 W. Examples for usage include LED lighting systems, cell-phone charging and power for wireless networks. The goal is to make a very high quality system at a fraction of the cost of current systems. Currently it consists of a self-made solar panel build from solar cells, a MSP430 based charging and control module, and a rechargeable LiFePo4 battery. The open hardware approach allows collaborative development, support and building instructions for users worldwide. This could be especially interesting for makers in Africa and other parts of the world without grid connectivity in rural areas. Success of photovoltaic based systems is slowed down by a scarcity of skilled people and high costs. Open source hardware and internet comunities can provide essential information for self-learning the required skills to assemble, develop and install such systems.
