soiling mitigation

New model to predict PV module cleaning cycles and resulting profits

A group of scientists in Bangladesh has developed a model to determine the optimal cleaning schedule for a PV installation at any location in the globe, requiring only the average insolation and soiling rate for a given site to make the calculation. The study also draws new conclusions regarding the influence of sandstorms and rain on soiling, and aims to be among the first studies to paint a global picture of soiling trends by region.

Anti-soiling nanocoating for large-scale PV

Dutch company Rads Global Business has developed an anti-soiling coating for solar PV modules that is claimed to reduce cleaning cost by around 60%. The anti-reflective and anti-corrosive coating is also said to mitigate potential-induced degradation (PID).

Promising soiling mitigation solutions should not be left to gather dust

A study has estimated the cost of PV project soiling may increase from €3-5 billion last year to €4-7 billion by 2023 due to more extensive deployment in high insolation and soiling-affected regions, such as China and India. The authors of the paper outlined the potential of soiling mitigation technologies while stressing more R&D is needed to reduce costs and for the adoption of such measures on a larger scale.
