Title: Investigate the effects of light intensity and color on the energy output of a PV array.
Course: Sustainability and Renewable Technologies (21053) > Section: Examining Renewable Energy

Investigation should include using a device (e.g., multimeter, microcontrollers, microprocessors or other computers with sensors and indicators) various light sources (i.e., natural and artificial), and the visible light spectrum.
