Measuring cleanness of solar photovoltaic systems with Soltell technology

The impact of soiling, including dust and dirt is accumulating over just several weeks to over 20% impact on performance in Mediterranean regions, susceptible to dust from Middle Eastern and North African deserts. Furthermore, in urban environments an even more dramatic impact is made by fast accumulation of dust and soot. Manual or automatic cleaning is hence required to bring solar photovoltaic (PV) performance to optimal values. The means and the frequency of cleaning is of course a function of several variables, including system size, electricity generation tariff and local factors.

However, the timing of cleaning and its effectiveness for rooftop facilities has so far been a matter of an educated guess. The cleanness measurement capability of Soltell's management platform is a unique predictive maintenance tool for rooftop PV in terms of cleaning schedule, as well as optimizing other aspects of maintenance.

Presenting our proprietary cleanness measurement of rooftop solar PV systems - ability to detect the precise soiling impact on PV system performance with no extra hardware, utilizing our Industrial IoT capability coupled with artificial intelligence. Above, you can see the comparison of automatically cleaned PV system (daily), periodically cleaned PV systems (once 2-3 weeks) and rarely cleaned PV system (once a season).
