Open Source Low-Cost Power Monitoring System, Shane W. Oberloier, Joshua M. Pearce
Open Source Low-Cost Power Monitoring System, Shane W. Oberloier, Joshua M. Pearce
Joshua M. Pearce
This study presents an entirely open-source, low-cost power monitoring system capable of many types of measurements including both loads and supplies such as solar photovoltaic systems. In addition, the system can be fabricated using only open source software and hardware. The design revolves around the Digital Universal Energy Logger (DUEL) Node, which is responsible for reading and properly scaling the voltage and current of a particular load, and then serializing it via an on-board ATTiny85 chip. The configuration of the DUEL node allows for custom sensitivity ranges, and can handle up to 50 A and 300 V. Up to 127 …

Recent advances in the use of plasmonic metamaterials to improve absorption of light in thin-film solar photovoltaic devices has created a demand for a scalable method of patterning large areas with metal nanostructures deposited in an ordered array. This article describes two methods of fabricating ordered 2D nanosphere colloidal films: spin coating and interface coating. The two methods are compared and parameter optimization discussed. The study reveals that:
• For smaller nanosphere sizes, spin coating is more favorable, while for larger nanospheres, the angled interface coating provides more coverage and uniformity.
• A surfactant-free approach for interface coating is developed …

A source of large surface areas for solar photovoltaic (PV) farms that has been largely overlooked in the 13,000 United States of America (U.S.) airports. This paper hopes to enable PV deployments in most airports by providing an approach to overcome the three primary challenges identified by the Federal Aviation Administration (FAA): (1) reflectivity and glare; (2) radar interference; and (3) physical penetration of airspace. First, these challenges and precautions that must be adhered to for safe PV projects deployment at airports are reviewed and summarized. Since one of the core concerns for PV and airport symbiosis is solar panel …
Design Of Post-Consumer Modification Of Standard Solar Modules To Form Large-Area Building-Integrated Photovoltaic Roof Slates, Joshua M. Pearce, Jay Meldrum, Nolan Osborne
Design Of Post-Consumer Modification Of Standard Solar Modules To Form Large-Area Building-Integrated Photovoltaic Roof Slates, Joshua M. Pearce, Jay Meldrum, Nolan Osborne
Joshua M. Pearce
Building-integrated photovoltaic (BIPV) systems have improved aesthetics but generally cost far more than conventional PV systems because of small manufacturing scale. Thus, in the short and medium term, there is a need for a BIPV mounting system that utilizes conventional modules. Such a design is provided here with a novel modification of conventional photovoltaic (PV) modules to allow them to act as BIPV roofing slates. The open-source designs for the mechanical components necessary to provide the post-consumer conversion for a conventional PV module are provided, and prototypes are fabricated and installed on a mock roof system along with control modules …

Energy security and its application is the key for economic growth to any country and state. The conventional generation is also the source of greenhouse gas emission attributing to global warming and has has adverse impact on climate. Therefore, a global shift towards sustainable renewable energy generation is being witnessed. India is blessed with abundant solar energy and if harnessed efficiently, Solar energy is extremely beneficial as it is non polluting and its generation can be decentralized. The state of Rajasthan receives maximum solar radiation Intensity in India with very low average rainfall. It also has desert land available in …
Optimal Design Of A Pv/Fuel Cell Hybrid Power System For The City Of Brest In France, Dr. Adel A. Elbaset
Optimal Design Of A Pv/Fuel Cell Hybrid Power System For The City Of Brest In France, Dr. Adel A. Elbaset
Dr. Adel A. Elbaset
This paper deals with the optimal design of a stand-alone hybrid photovoltaic and fuel cell power system without battery storage to supply the electric load demand of the city of Brest, Western Brittany in France. The proposed optimal design study is focused on economical performance and is mainly based on the loss of the power supply probability concept. The hybrid power system optimal design is based a simulation model developed using HOMER. In this context, a practical load demand profile of Brest city is used with real weather data.
