Locking Solar Tracking Bushing, Benjamin James Reed, Andrew Donald Maas, Angel Navarro-Iniguez, John Vincent Bruner

Mechanical Engineering

The contents of this final design review (FDR) outline the progress made by a team of four mechanical engineering students at California Polytechnic State University, San Luis Obispo to solve the problem of torsional galloping in solar tracker panels since the preliminary design review. The project proposed by the sponsor, Christian Friedrich, on behalf of ARaymond is a design for a friction based braking system integrated into a redesigned bushing.

The CDR contains details about the system design, the design justification, the manufacturing plan, and design verification plan. In the system design section, the four manufacturing subsystems (bushing mount, actuation, …

Skip The Grid: Installation Of Solar Powered Refrigeration In The Navajo Nation, Connor T. Avrit

Construction Management

The Skip the Grid project was a project completed with the joint efforts of California Polytechnic State University, San Luis Obispo (Cal Poly) and many other company sponsors including Solv Energy, Dometic, Goal Zero and Heart of America a nonprofit. Skip the Grid’s project goal and outcomes was to improve the quality of life and provide clean sustainable off grid energy to families within the Navajo Nation. The Navajo Nation is located in the Four Corners region of the United States with approximately a third of its residents without the means or circumstances to be tied into grid level power. …

Solar Solution For Mini-Rover, Michaella Ochotorena, Derick Louie, Jonathan Cederquist, Collin Petersen, Cole Korchek

Mechanical Engineering

This project focuses on designing, building, and testing a functional prototype of a collapsible solar array on the mini Mars rover being developed by client and sponsor, Mr. Rich Murray. Although many previous collapsible solar arrays have been deployed for space missions, the previous solar-powered Mars rovers only deployed their arrays once upon landing. This solar array will be able to collapse and deploy multiple times to allow for greater rover mobility and stability when the rover is not charging. This system is critical to the success of the rover project because it provides power without which the rover cannot …

Can The In-House Installation Of Solar Panels Increase Residential Builder’S Profits?, Garrison M. O'Marr

Construction Management

The purpose of this paper is to analyze and determine if the In-house installation of solar panels by Residential Builders will lead to increased profits. Specifically, this pertains to Large Residential Developers that are focused on building single-family home developments with greater than 25 homes. With the demand for solar power in new homes continuously rising year after year, it is smart to find more profitable ways to install these systems, one of which is self-installation performed by the General Contractor. The Methodology of research I used is a combination of primary and secondary research, as well as interviews with …

Skip The Grid: Giving Power To Navajo Nation, Ryan J. Schacherbauer

Construction Management

Skip the Grid is a project organized by Heart of America, a nonprofit, looking to improve the education and overall wellbeing of children and their families. Many residents within Navajo Nation do not have access to continuous power and rely on temporary generators or car battery to obtain any kind of electricity. Heart of America partnered with the Red Mesa School District to identify families that did not have power, which was impacting the children’s ability to complete their online schoolwork. This senior project was comprised of an interdisciplinary team responsible for installing a working solar system on twelve homes …

Solid Thermal Storage As An Energy Storage Device In Insulated Solar Electric Cookers: Thermal Modeling And Experiment, Michael Antonio Fernandez

Physics

The use of solid thermal storage (STS) as an energy storage device in insulated solar electric cookers (ISEC) was explored using a thermal simulation before retrofitting an existing cooker without energy storage and testing it under several conditions. STS sizing, material selection, and geometry were examined from both theoretical and practical perspectives and re-examined following experimental results. Characterization of the system’s thermal interfaces and methods to improve their thermal conductivities were investigated resulting in several performance enhancements to the system.

Living Off The Grid With Renewable Energy: A Case Study, Jake Reid O'Balle

Construction Management

The trend towards green, sustainable living is on the rise and the benefits are continuing to make noise in the world of homeowners. In this project, the benefits of renewable energy and consumer preferences were analyzed and applied to off-grid living in the form of a case study. It was found that the majority of homebuyers are concerned about the environment and wanted an environmentally friendly home but are not willing to pay more in order to achieve these desires. This information spurred the need for a detailed assessment of the feasibility of sustainable off-grid living. After conducting extensive research, …
