Reducing Degradation Rates with Earth Mount Solar® PV


Solar module degradation is an important consideration when estimating the future production of a utility-scale photovoltaic (PV) system. Degradation can happen for a variety of reasons and is, at a fundamental level, unavoidable. It is not possible to design a solar installation that does not experience some amount of module degradation, whether as a result of design limitations, environmental impacts, or other factors. It is possible, however, to significantly reduce degradation, thus maximizing your PV system’s future power production and protecting the return on your investment.

Earth Mount Solar® PV systems were designed to do precisely this. Because the solar modules in an Earth Mount Solar® PV system are installed directly on the ground, they attenuate several of the causes of module degradation, such as cyclic wind loading, thermal cycling, non-uniform soiling, and potential-induced degradation (PID). This innovation, combined with a higher DC/AC ratio, enables Earth Mount Solar® PV systems to reduce annual effective energy loss by approximately 50% when compared to single-axis tracker (SAT) systems.
