REFERENCE CELL CLEANING ROBOT IN PHOTOVOLTAIC SYSTEMS
Project no. 601 · Status: Kapanmış · 2016
Summary
With the rapid growth of large scale photovoltaic power systems (PVPS) installations in Turkey, investors expectation of lucrativeness on the increase. Especially in Turkey, roughly 3.4 GWp on-grid PVPS was installed the last year at 2017. However with that rush, in a developing country such as Turkey, may lead many workmanship mistakes on the planning, implementation and operation process due to lack of qualified work force. To compensate that faults, it very substantial to put a monitoring devices to plant. Not only for the energy production, also for the incoming irradiance and temperature. Because only that way the performance ratio of the system can be achieved. The irradiance sensor which is the most important sensor for calculating performance ratio, can heavily effected by soiling, same like the photovoltaic modules [1, 2]. Soiling is very significant factor in Turkey for PVPS. This soiling factor effects the results for the irradiance monitoring element, thus performance ratio. In order to get a good homogeneous results it has to be cleaned in calculated intervals, regarding to soiling intensity. To prove that idea in this article, there is a comparison between 2 irradiance sensor’s data. The one which was left as a reference, untouched and the other one was cleaned by the self-made robot in precalculated orders. At the end, the results confirmed that there is an observable difference in collected irradiance.
