This astute article explores an important concern for the solar industry: the degradation rate for solar photovoltaic (PV) modules. The rate itself is inherently low, while the uncertainty in measuring it is inherently high - and there are uncertainties around the impact of degradation. Developers and module suppliers often seek an optimistically low degradation rate assumption as this can have an increase in the economic value of a project. Mathias Steck of the Energy & Renewables Advisory at DNV GL strongly encourages module manufacturers and other stakeholders to share long-term data which could further the industry’s understanding and insights regarding the observed benefits of this critical topic.
