چکیده
Soiling of PV modules is an issue causing non-negligible losses on power plants, between 3 and 4% the total energy production. Cleaning most common way to mitigate soiling. The impact cleaning activity can be significant, both in terms cost resources consumption. For these reasons, it important monitor predict soiling profiles establish optimal schedule. Especially locations where raining irregular or desert winds carry a high concentration particles, also know how precipitation dust events affect ratio. This paper presents new model based environmental conditions that helps decision-making process was validated by analysis five large grid-connected plants Spain over two years operation, with 200 MW. comparison sensors at included. Excellent results were achieved, mean difference being 0.71%.

متن کاملReview on Single-phase PV Inverters for Grid-connected Applications
In this paper, a review of PV inverters is reported based on converter characteristics as the number of energy processing stages, the presence of a transformer (high-frequency or 50Hz transformer), and the adopted configuration of the PV field. In particular, the considered solutions have been evaluated depending on efficiency, input current ripple and life-time of the capacitors coupling with ...
متن کاملHighly efficient flyback microinverter for grid-connected rooftop PV system
This paper proposes a high efficiency DC-DC flyback converter with a resonant full-bridge inverter to use in PV systems. The flyback converter is composed of a resonant active-clamp circuit that limits the voltage stress and provides zero voltage switching (ZVS) turn-on and turn-off of the power switches. Therefore, the switching losses of the high frequency primary switches are negligible. A r...

متن کاملModified Multilevel Inverter Topology for Grid Connected Pv Systems
Multilevel converters offer high power capability, associated with lower output harmonics and lower commutation losses. Their main disadvantage is their complexity, requiring a great number of power devices and passive components, and a rather complex control circuitry. This paper proposes a single-phase sevenlevel inverter for grid connected PV systems, with a novel pulse width-modulated (PWM)...
