6 FAQs about [Dust removal high frequency power supply energy storage]
What is dust removal efficiency if EDS is activated before dust loading?
The dust removal efficiency when the EDS was activated before dust loading was 97.6% as compared to 91.5% when the EDS was activated after the dust has been deposited on the surface. The power consumption was between 0.17 and 0.48 W/m 2 and increased with an increase in frequency reaching up to 10 W/m 2 .
Is a dust loading level relevant to solar energy field operations?
A more practical approach of incorporating a dust loading level that is relevant to solar energy field operations and at 20° surface inclination was undertaken by Guo and Javed (2017). The high voltage of amplitude: 3, 6, and 9 kVpp with a frequency of 1 Hz was used in the experiments.
How much power does a solar panel recover after dust removal?
To measure the power recovery from the solar panel after dust removal, the researcher employed 150 g/m 2 dust loading with 20° inclination at 0.7 kVpp/mm and 0.2 Hz. The output power of the panel without dust was 97%. After dust application the output power decreased to 60% which was regained to 90% after the activating EDS .
Does particle size distribution affect dust removal efficiency?
Johnson et al. (2005) studied how dust removal efficiency is affected by Particle Size Distribution (PSD) and particle charge. The testing was carried out with a 6 kV 2-phase AC voltage running applied in a square waveform and a 5 Hz frequency in the simulated Martian environment.
Which wave is most effective for dust removal?
The study found that the square wave was the most effective for dust removal, consistent with a study by Sims et al. . Moreover, at low-frequency operations, the authors showed that the particles were transported in the direction of the traveling wave, while the particle transport was closely synchronized with the wave speed.
Does cyclic operation reduce dust removal efficiency?
In the cyclic-operation mode, new dust loading for 20–30 cycles was carried out on the surface without cleaning. The results showed that in the cyclic-operation mode, the removal efficiency decreased with an increasing number of cycles, and the persistent dust from the previous cycle was not removed in the following cycles .
