One study has shown that panels in very dusty environments with infrequent rain resist dust deposition best when angled at around 26%. Now let’s consider the direction that the roof surface faces.

The same study suggested energy losses of 13.5% and 26.2% for vertical and horizontal installation, respectively. In general, as the tilt angle increases, the dust accumulation on PV panels decreases due to gravitational effect on dust particles (Mekhilef, Saidur, and Kamalisarvestani Citation 2012).

One possible solution is a coating over the surface of solar panels. An example of this strategy is a hydrophobic coating, meaning it repels water. If the panel is at a steep enough angle, dew or rain would run down its surface and wash away the dust.

In this study, the phenomenon of dust deposition was studied experimentally in the urban area at one of the most polluted cities of Europe, i.e. Kraków, Poland. Solar photovoltaic panels tilted at angles 15° and 35° were exposed to atmospheric conditions for the period of eighteen months from 6 May 2017 until 30 November 2018.

Generally, solar panels should not be placed flat, but should be inclined at an angle where the solar panel's surface is not too steep or too shallow (Khan et al., 2023). This can cause dust to accumulate or be blown away too quickly.

6 FAQs about [What is the angle at which photovoltaic panels do not accumulate dust ]

What factors affect dust accumulation on PV panels?

A surface which can get effected by the heat can get sticky while promoting adhesive residues, dust, and soiling. Similarly, the tilt angle plays a major role since an inclined surface attracts less gravity and hence less dust accumulation as compared to a flat or horizontal surface. Fig. 7. Factors involved in dust accumulation on PV panels. 2.2.

Are solar panels prone to dust accumulation?

Dust accumulation is a continuous challenge for solar PV panels, particularly in desert areas. Mega Solar Parks and Ultra Mega Solar Parks are sited mostly in the desert-prone areas for their sheer size, and they are likely to be more vulnerable to dust accumulation, when compared with those in urban areas.

Do solar PV modules accumulate dust particles in urban air polluted areas?

In this work, an experimental investigation was carried out to measure natural dust particle accumulation on the front surface of PV modules in the urban air polluted area under various environmental conditions. Field experiments were performed on the 14 panels tilted at angles 15° or 35°.

Why do photovoltaic panels have dust particles on the front surface?

The findings of the research can be summarised as follows: 1. Dust particle deposition on the front surface of the photovoltaic panel is not linearly dependent upon the duration of exposure, but it is a complex phenomenon which is influenced by all-weather parameters, among others.

What is dust accumulated PV panels?

Dust accumulated PV panels — An integrated survey of factors, mathematical model, and proposed cleaning mechanisms. Handy information to readers, engineers, and practitioners. A possible sustainable solution to challenges of water availability and PV systems cleaning mechanisms.

How long are solar photovoltaic panels exposed to atmospheric conditions?

Solar photovoltaic panels tilted at angles 15° and 35° were exposed to atmospheric conditions for the period of eighteen months from 6 May 2017 until 30 November 2018. Dust samples were collected from the panels for the exposure period which ranged from one day up to 11 days.
