The objective of the design experiment is to analyze the effects of adding solar panels to an electric remote controlled airplane. The initial set of control flights were performed by a plane driven by energy from Lithium Ion Polymer (LiPo) battery power. A second set of flights will feature the addition of solar panel energy. Solar panel energy will provide charge of the battery while in flight at the cost of adding weight and drag to the plane. The effects of this trade off were analyzed; the data extracted from static and dynamic flight tests show predicted results of 20% increase of inflight duration. Future work will make solar panel energy the sole source of energy to support solar plane during daytime flights.
