Long-Term Durability Of Solar Photovoltaic Modules, Chibuisi Chinasaokwu Okorieimoh, Brian Norton

Conference papers

Solar photovoltaic (PV) panels experience long-term performance degradation resulting in lower like-per-like efficiencies and performance ratios when compared with their initial performance. Manufacturers of solar photovoltaic modules usually guarantee the life span for more than 20 years. It is therefore necessary to track and mitigate degradation of PV modules over this period to satisfy such guarantees and beyond this period to identify maintenance and repair requirements. Degradation of solar PV modules makes them less efficient, less reliable and, ultimately, inoperative. This paper reviews relevant literature to discuss:

• Causes of efficiency reductions in photovoltaic cells

• Ways to achieve long-term durability of …

Case Study: Google’S Unique Canopy Styled Construction, Ray A. Cuevas

Construction Management

In today’s rapidly changing world, builders are pushing to implement more sustainable practices and incorporate innovative techniques to integrate green practices into their structures. One of the latest examples of this push towards sustainability is seen in Google’s new headquarters, Charleston East located in Mountain View, California. Combining their widely known mission to provide a positive work environment for their employees with their passion to be more environmentally friendly, Google has set out to create a Living Building with LEED Platinum certification. In order to accomplish this Google has collaborated with Bjarke Ingels Group, Heatherwick Studio, and Hathaway Dinwiddie. The …

Proposal For A New Construction Management Emerging Trends Elective Course: Principles Of Solar Construction, Nicholas J. Gairaud

Construction Management

California Polytechnic State University (Cal Poly) prides itself on its learn by doing motto which encourages students to participate in hands-on projects and choose elective courses about topics they are interested in. This project is an outline for an Emerging Trends elective course that aims to fill the gap between what students learn in school and what they see in the field. Over the past decade, the use of on-site solar energy generated has skyrocketed in the commercial and residential sectors. The purpose of this course is to inform students about solar requirements and to lay the groundwork for students …

Neca Ghana Project, Michael T. Klee

Construction Management

Cal Poly’s motto is, “Learn by Doing" and for Cal Poly’s NECA Chapter, this isn’t simply a motto, but a directive for proactive change. For my senior project I will be leading the Cal Poly NECA chapter in the design, pre- fabrication and construction of a 5-7kw solar array, community center, ice production room and technology room in the remote fishing village of Agbokpa, Ghana. The solar array will power multiple industrial DC freezers, high efficiency LED lighting and charging stations while additionally powering water filtration and irrigation systems. Like many other fishing villages around the world, Agbokpa has no …

Solar Powered Parking Lot Lights, Jordyn Taylor

Sustainability Conference

Solar energy is a renewable resource growing exponentially around the country over the past few decades. Solar energy works through the use of photo-voltaic cells, which work to convert energy from sunlight into electricity. This is done within solar panels, which are then connected to batteries for energy storage to use as needed. As production has increased over past decades, the cost for solar panel hardware and installment has thus fallen to meet consumer need. While most common implementations include solar panels attached to one’s home or solar panel ‘fields’ for charging entire towns, there has been a steady rise …
