Dust accumulation on the surface of photovoltaic (PV) modules significantly reduces the amount of light reaching the cells and can lead to decreased power output and instability of the system.. Dust accumulation of 20 g/m 2 on a PV panel reduces short circuit current, open circuit voltage and efficiency by 15–21%, 2–6% and 15–35% respectively.. It is found that daily PV power losses and monthly efficiency reduction due to dust in some locations is more than 1% and 80%, respectively, which is relatively high.. For instance, one report states that one gram of dust accumulated on a photovoltaic panel of size 12 cm × 8 cm (hence 1/96 g/cm 2 ≈ 0.01 g/cm 2) reduces efficiency by 60%. [6] [pdf]

FAQS about Dust on photovoltaic panels affects efficiency

Does dust accumulation affect PV module efficiency?

The effect of dust accumulation on PV modules has been studied very briefly by them. Efficiency of solar panels is also reduced by dust deposition.
