The performance of seven differing types of residential water heating systems was compared in a side-by-side test configuration over a full year period. The Hot Water System Laboratory (HWS Lab) test facility at the Florida Solar Energy Center (FSEC) in Cocoa, FL was used for the tests. Simultaneous hot water draws occur on a daily basis for the following hot water heating systems at the HWS facility with the evaluation of two draw profiles:
A case study of photovoltaic attic ventilator fans was conducted on an occupied single family home in Central Florida. Two fans were installed at mid-summer in an instrumented home where attic air temperature, meteorological conditions and space cooling electric power were measured. The home already had an attic radiant barrier, but still experienced attic air temperatures in excess of 130oF.
Notes, observations and recommendations about the use of batteries in small stand-alone photovoltaic system drawn from over a decade of research at FSEC. The most critical findings were battery life and the importance of an adequate PV array-to-load ratio.
The National Solar Jobs Census 2010 is the first attempt to quantify the current employment and projected growth of the United States solar industry and is based on a statistically valid sampling of employers throughout the nation. The rapid increase of solar energy generation has warranted a credible study that examines the size and scope of the industry that until now, has been lacking.
This program guide outlines the application and review procedures for obtaining the necessary permit(s) to install a solar energy system for a new or existing residential building. The guide also describes what system siting or design elements may trigger the need for additional plan review.
