LiFePO4wered/Solar1 – Solar power supply for IoT devices

Patrick Van Oosterwijck @ hackaday.io writes: Solar power is not trivial, especially if it needs to be reliable and have a long lifetime for outdoor deployment such as IoT sensor nodes. This project is an effort to create a complete, easy to use solar power system that provides the...

Circuit implements photovoltaic-module simulator

José M Blanes and Ausiàs Garrigós writes: Electronics engineers often use photovoltaic-module simulators to test dc/dc-power converters, inverters, or MPPT (maximum-power-point-tracking)-control techniques. The use of these simulators lets you work in the laboratory with...

MPPT solar charger

Lukas Fässler show us his progress on the MPPT solar charger: One of my main goals with this design is to achieve very low standby current, somewhere in the tens of microamps. The basis for this is a low-power buck on the basis of a Texas TPS62120 where the microcontroller can...

PV cell string optimizer boosts solar panel output up to 30%

Maxim presents its Cell-String Optimizer as the first IC to perform MPPT (maximum power point tracking) at low level in a panel; it allows photovoltaic (PV) panels to harvest significantly more energy and simplifies design complexity for solar installation projects. by Graham...
