HOW CAN WE MAKE SOLAR PANELS MORE RELEVANT IN AEROSPACE ENGINEERING?,JACOB LENOX, RISHEE JAYASIMHA

WHAT ARE SOLAR PANELS? Solar panels are a technology which converts light into electricity 1 Utilize any source of light (usually sun) to produce electricity 1 Solar panels are a collection of solar cells 1 Solar cells produce more electricity when 1 : There are more grouped together Light hits them more directly (higher intensity) 1. "Power." What Are Solar Panels? N.p., n.d. Web. 03 Nov. 2015.
