[Under Construction]
 

Welcome to the Photovoltaic Syst ems Data Network, a gateway to photovoltaic systems information and performance data at the Florida Solar Energy Center.   This site is designed to facilitate the process of archiving and accessing data collected from dozens of PV systems in the field monitored by FSEC's Photovoltaics and Distributed Generation Division.  From this site, FSEC researchers and other interested parties can view, print and download a variety of daily and mont hly plots, analysis report and summary data for these systems.
 

About the Process

Data on this site is collected from data acquisition equipment measuring and recording parameters at PV systems in the field.  On a regular basis, data is autom atically downloaded from these sites to FSEC's Experimental Data Base Management System, where the raw data is processed and archived for later retrieval and analysis.  On a daily basis, an analysis procedure is automatically executed to produce daily plots and summary data for each experiment.  Other analyses are conducted on a monthly or longer basis where applicable. After these daily analysis procedures are completed, the output is converted to Adobe^TM Portable Document Forma t (PDF) and ASCII text files and automatically updated on FSEC's WWW server once per day.
 

Accessing Data from this Site

Data on this site is accessed by simply clicking on the desired Alphabetical or Regional listings in the above menu bar, which links to a directory of individual experiments.  At the next level, you will see a directory listing of files, beginning with dated subdirectories (or folders), containing older processed data.  Next, there are two ASCII text files containing daily summary data for each site, and include information such as daily energy production, system efficiencies and normalized performance parameters useful for comparing systems of different types and sizes in different locations. An explanation of th e parameters stored in these files is given in the header for each file.  These text files can be viewed and saved from any browser for importing into spreadsheet applications.  Finally, there is a list of date-stamped PDF files that contain charts and data summaries for average daily system performance, and are available for a daily, monthly, and longer basis as applicable.  Data older than one month is usually archived in the subdirectories. These PDF files can be viewed, printed and downloaded using the free Acrobat Reader software.
