Solar panels generally contact the mounting structure only along the surfaces of the aluminum frame surrounding the perimeter of the panel. With no support in the middle of the panel, front side mechanical loads from snow, wind, and human factors can

Some crystalline silicon PV system underperformance is due to the presence of cracked solar cells, and this represents a financial risk for both already installed and future systems. This work describes compressive stress strategies and rear side pre

Cell cracking presents a serious risk for the long term reliability of c-Si photovoltaic modules. Cracks may not initially result in performance loss, but over time performance may degrade as the module experiences stresses in the field such as tempe

Manufacturing, shipping & handling, installation, and in-field loading of photovoltaic solar panels are common contributors to the creation of cracks within the cells of a panel. Many cracks initially cause little or no power loss in the panel, but s

Several methods have been determined for measuring the contact resistivity of solar cell devices, but these methods are all either destructive in nature or require the fabrication of special metal contacts. In this paper, we present a non-destructive

The measurement of contact resistivity between the grid metallization of a solar cell and the underlying silicon wafer is most conveniently performed by cutting strips from solar cells rather than fabricating dedicated structures with variable spaced

Mechanical load tests are a commonly-performed stress test where pressure is applied to the front and back sides of solar panels. In this paper we review the motivation for load tests and the different ways of performing them. We then discuss emergin

During testing of a new contact resistance measurement system (ContactSpot), we observed several unexpected results. TLM theory predicts a linear dependence of the resistance measurements vs probe spacing, and from this data set the contact resistanc

To reduce the cost of its String Ribbon™ solar panels, Evergreen Solar has developed automated laser cutting equipment that enables cutting silicon ribbon into wafers as it emerges from the growth furnaces. The laser source was chosen based on its
