Assessing effectiveness of icephobic coatings on PV systems located at high latitudes


A analysis group in Norway analyzed snow deposits on photovoltaic panels and the ensuing power loss by means of PVsyst software program and used the so-called Marion’s algorithm (MA) for evaluating the sliding coefficient. It discovered that the coatings can successfully cut back the power loss resulting from snow and ice however stated that the industrial feasibility of those supplies must be additional investigated.

Scientists from the Norwegian College of Science and Know-how (NTNU) needed to research the impact of icephobic nanomaterial coatings on PV techniques positioned at excessive latitudes and located that these supplies can successfully cut back the buildup of snow and ice.

“The extra PV power manufacturing achieved with this resolution is determined by the weather conditions the place the case research is positioned,” stated Mattia Manni, the lead creator of the analysis. pv journal. “Specifically, it is determined by the quantity of snow and ice gathered on the PV floor all year long.

Manni additionally defined that the The icephobic supplies examined in photo voltaic modules are nonetheless removed from being obtainable available in the market as a result of they present a excessive charge of degradation. Due to this fact, in the intervening time it’s not attainable to supply details about their prices and the financial feasibility of the interventions,” he stated.

The analysis group analyzed the snow deposits on the photovoltaic panels and the ensuing power loss by means of the PVsyst software program and used the so-called Marion’s algorithm (MA) for the analysis of the sliding coefficient.

“The proposed workflow strikes from an evaluation of snow deposits on PV panels and the resultant discount of irradiance on the aircraft of array (POA) to an analysis of the affect of icephobic nanomaterials on lack of snow,” the group defined, noting that this evaluation was made. for 3 places in Norway – Oslo, Bergen, and Trondheim.

By way of this evaluation, carried out between November and April, the scientists discovered that the snow loss reached 32.75 kWh/m.2 in Oslo, 25.05 kWh/m2 in Trondheim, and 5.85 kWh/m2 in Bergen. Using icephobic coatings resulted in a discount in power lack of 12.05 kWh/m2 in Oslo, at 10.00 kWh/m2 in Trondheim, and at 3.35 kWh/m2 in Bergen.

“Due to this fact, the effectiveness of icephobic coatings is the same as 65% in Oslo, 60% in Trondheim, and 45% in Bergen,” they added, stressing that these information must be verified by integrating with different experimental information from totally different high-latitude places and PV techniques, whereas additionally performing a sensitivity evaluation of the ice adhesion energy of PV panels.

Their findings are within the research”The affect of icephobic nanomaterial coatings on photo voltaic cell panels at excessive latitudes,” revealed in Photo voltaic Vitality.
