Deploying Mobile Pv Emergency Power System In A Disaster, Florida Solar Energy Center, William Young

FSEC Energy Research Center®

Disasters can be as destructive as Hurricane Katrina, leaving several hundred-thousand people homeless, or as minor as an afternoon thunderstorm that brings down local power lines to your home. After a disaster, utility services may be damaged or destroyed, leaving people without water, sanitation, communication and electricity. In response to a disaster, first responders are deployed with life supporting resources, such as water, food, and medical supplies. Energy resources are often lacking, making recovery efforts difficult in our high-tech world of cell phones, television, computers, refrigerators and many other electronic devices.

After a disaster, the long time tradition used to …

Geographic Variation In Potential Of Rooftop Residential Photovoltaic Electric Power Production In The United States, Florida Solar Energy Center, Matthew Lombardi

FSEC Energy Research Center®

This paper describes a geographic evaluation of Zero Energy Home (ZEH) potential, specifically an assessment of residential roof-top solar electric photovoltaic (PV) performance around the United States and how energy produced would match up with very-efficient and super-efficient home designs. We performed annual simulations for 236 TMY2 data locations throughout the United States on two highly-efficient one-story 3-bedroom homes with a generic grid-tied solar electric 2kW PV system. These annual simulations show how potential annual solar electric power generation (kWh) and potential energy savings from PV power vary geographically around the U.S. giving the user in a specific region an …

Study Guide For Photovoltaic System Installers And Sample Examination Questions, Florida Solar Energy Center, James Dunlop

FSEC Energy Research Center®

This Study Guide presents some of the basic cognitive material that individuals who install and maintain photovoltaic (PV) power systems should know and understand. This information is intended primarily as a Study Guide to help individuals better prepare for the NABCEP PV installer examination but does not provide all of the materials needed for completing the certification examination. Knowledge of the information presented, knowledge of pertinent sections of the National Electrical Code and appropriate experience and qualifications, are generally required of those applying for and completing the NABCEP certification process. Applicants and certificants are also reminded that local installation codes …

Qualitative And Statistical Analysis Of The Florida Photovoltaic Rebate Program, Florida Solar Energy Center, Jennifer Szaro

FSEC Energy Research Center®

The Florida Photovoltaic (PV) Rebate Program, which began in March of 1999, has led to the installation of 52 utility interactive PV systems in seven electric utility service territories. The Program offered $4 per installed DC Watt to Florida electric consumers who installed grid-connected photovoltaic equipment in accordance with a series of quality control requirements developed and administered by the Florida Solar Energy Center. All rebated installations are currently being monitored in an effort to collect statistically significant reliability, performance and cost data on grid-connected PV systems. Funding for this program was provided through a one-time grant from the Florida …

Recommendations For Maximizing Battery Life In Photovoltaic Systems: A Review Of The Lessons Learned, Florida Solar Energy Center, James Dunlop

FSEC Energy Research Center®

This report contains notes, observations and recommendations about the use of batteries in small stand-alone photovoltaic (PV) systems. The conclusions of this work are based on the results of more than a decade's worth of battery testing at the Florida Solar Energy Center and related work with Sandia National Laboratories, the PV industry and user groups. The most critical findings were the relationship between battery state-of-charge and battery life and the importance of an adequate PV array-to-load ratio.
