1) Archeos Energy has developed a solution called "Argy" that combines solar and biogas technology to efficiently power batteries and provide electricity for rural populations in Africa who lack access. 2) "Argy" uses an inverter, microcontroller, battery, biogas digester, methane tank, methane electric engine, and solar panels to manage the transition between solar and biogas power sources to recharge batteries and ensure continuous energy access. 3) The system is expected to have a lifetime of at least 15 years and be monitored remotely through sensors and an Arduino/IoT setup connected to the microcontroller.
