WHAT IS A SOLAR TRACKER?
• A solar tracker is a device that orients various devices toward
the sun. Payloads can be photovoltaic panels , reflectors, lenses
or other appliances.
CONCEPT AND THEORY
• Collect energy as efficiently as possible by using no motors
(electric or gas).
• Track the sun by using the earths gravitational pull on the
system to create dynamic actuation of the solar panel.
• Designed for the self sustainable home user, small villages in
developing countries, alternative energy learning resource.
• Gain knowledge of solar tracking systems (teaching tool).
FRAME DESIGN
• Current prototype designed to hold 1-2 small panels
• 40° above eastern horizon to 40° above western horizon
• 100 ̊latitudinal rotation: 15°/hour
• 90° lock out position: flow is blocked and weight support pin inserted
