The final project is a solar-powered charging system for powering small devices using a USB socket. Energy is collected by a 100 watt solar panel mounted to the roof of the school. This energy is directed inside to a charge controller, which regulates the power flow, and then sent to a 12 volt, 40 amp hour battery to be stored for later use. | |||

Abstract
One paragraph summary of your project from background to discussion and next steps.
Background
Redwood Coast Montessori (RCM) is a public charter school located next to the Manilla Sand Dunes in Arcata, CA. Founded in 2005, the program started out with one classroom on a traditional public school campus in Eureka, CA. In June 2012, the Arcata School District approved Redwood Coast Montessori’s charter application to become a K-8 independent public charter school beginning on July 1, 2013. The Montessori style of teaching acknowledges that children in early childhood need to develop their cognitive abilities through experiences with their senses and different materials. As they grow, Montessori students at an elementary age apply what they have learned to real world experiences.

Final Design
The final project is a solar-powered charging system for powering small devices using a USB socket. Energy is collected by a 100 watt solar panel mounted to the roof of the school. This energy is directed inside to a charge controller, which regulates the power flow, and then sent to a 12 volt, 40 amp hour battery to be stored for later use.
