    Standardized Testing of Non-Standard Photovoltaic Pavement Surfaces

    Emerging photovoltaic products have expanded the applications for the technologies into markets previously unconsidered for what was thought to be a delicate electronic product. One company leading this effort, Solar Roadways, Incorporated, is producing pavement replacing photovoltaic systems and proposing their use in everything from sidewalks to runways. Current pavement testing methods cannot be applied to these non-homogenous structures to identify if they can support the required loads. However, the standards called out specifically for pavements may be able to be translated to these products and their non-homogenous structures and non-standard materials to identify if they are able to perform similarly to standard pavements. This research modified existing test standards in several ways: rigid pavements standards for advanced loading, structural adhesive standards for shear loading, structure specific standards for moisture conditioning, and application specific standards for freeze/thaw cycling. These modifications are due to the fact that the materials in these emerging products do not have established tests to evaluate their performance in non-traditional applications. The future of electronics is dependent on product unique applications. This, in turn, requires finding methods of testing them based on application, extrapolation, or correlation to traditional material testing which enables faster product development and subsequent roll out
