Solar Photovoltaic (PV) Product Showcase

Shining a Light on the Solar Power Product Development Front

Last year was a banner year for solar installations in the United States. According to the “U.S. Solar Market Insight Report,” produced by the Solar Energy Industries Association and GTM Research, the United States installed 1,855MW of photovoltaic (PV) solar systems last year — a 109% annual growth over 2010. Installations in the fourth quarter alone were nearly double the value of those posted in the third quarter, which also came in at a record high.

A quick review of the capacity added last year per market segment shows utility-scale installations led the charge — up 185%. Non-residential installations grew 127%, and residential was up 11%. And although the Section 1603 Treasury Program expired at the end of 2011, the Report goes on to forecast that U.S. market share will increase steadily over the next five years as the European markets continue to slow down.

The explosive growth in the PV industry in recent years, coupled with generous Department of Energy funding initiatives, has allowed researchers and manufacturers an opportunity to drive down product costs through use of new materials/technologies, greater efficiency levels, and improved production processes. New products are being introduced at a feverish pace, as manufacturers look to capitalize on this hot market.

In an effort to help you keep up with this growing market segment, we’ve tracked down the specs on 48 solar products and presented them in this special section. This diverse group of products includes clips, grounding connectors, inverters, combiner boxes, meters, analyzers, modules, connectors, mounting systems, and more. Whether you’re a newcomer to this market segment or a seasoned designer/installer, we’re confident you’ll find value in the diversity of the PV products presented in this roundup.
