The Solar Photovoltaics (PV) team designs and installs solar electricity systems in developing countries where power is less reliable or non-existent. Starting in 2020, the Solar PV team began collaborating with Tree 4 Hope—a nonprofit organization that partners with an orphanage near Guatemala City, Guatemala. Over the past year, the team has designed a solar system to be installed at the orphanage which will provide them with a cleaner and cheaper source of electricity. Thus far, the overall 5 kW solar panel system design including lead-acid batteries has been completed. Key components of the system consisting of the system controller, two charge controllers and the inverter have been programmed and tested, by plugging them into existing elements of the solar lab system, in preparation for installation in Guatemala. This poster details the progress accomplished this year in the design, testing, and programming of the Solar PV system including wiring considerations and communication with in-country suppliers for installation at the orphanage during May of this year.
