How to calculate the photovoltaic panel degradation rate
The calculation for solar panel degradation follows a simple exponential decay model, where the power output decreases by a fixed percentage each year. This model helps predict the panel's remaining capacity over time. Although seemingly simple, the estimation of this metric is not trivial when it comes to real operating conditions due to several factors that can influence its calculation. Actual solar production, savings, and payback periods depend on site-specific conditions including.
