Dallas, TX – June 10, 2014 – The Principal Solar Institute (The Institute), an online reference center and resource guide for commercial and utility scale solar markets, announces that industry experts have chosen "Lifetime Energy Production™ – A Simple Method for PV Module Comparison," as one of the Best Posters of PV America 2014. Matthew A. Thompson, Ph.D., executive director, Principal Solar Institute, will present at Solar Central Booth #245, Boston Convention and Exhibition Center, Boston, Massachusetts, 3:10 p.m., June 24, 2014. The PV Module Rating provides a quick and simple method for side-by-side comparison of photovoltaic (PV) modules to maximize return-on-investment and enhance the value of a solar project.

"Our PV Module Rating is based on expected energy production which is in stark contrast to the traditional dollars-per-watt benchmark that is based on power and is most often used for initial project finance decisions. In the long run, it is energy production that generates revenue, not power," says Thompson. "This important distinction must become a part of every due diligence analysis for investors, developers, installers and owners of PV solar projects. The PV Module Rating is calculated based on published characteristics of PV modules, and realistic cycles of sunlight and temperature. This provides for an unbiased metric because no module cost information is used."

Stakeholders can employ the PV Module Rating directly in a cost-benefit analysis of modules based on energy yield rather than on theoretical maximum power.
"The PV Module Rating has been used by renewable energy investors in their utility scale solar due diligence process, and by Solarize Frederick County as a mechanism to document installers' choice of solar system components," Thompson adds.
