Temperature deviation between surface of modules and thermal boundary layer increases by 10 K as the angular direction of wind flow changes to 30° N-E for the Duna Solar and the RWE schott solar modules, while it is slightly high for the Solarwatt module.
Here I show in the real-world operation of a larger scale photovoltaic generator that increases in wind speed can lead to small but notable energy losses, reflected in the mismatch losses.
In this paper, a new condition-monitoring method based on the nonlinear state estimate technique for a wind turbine generator is proposed. The technique is used to construct the normal behavior model of the electrical generator temperature.
This study proposes a wind forecasting-based MPC that uses wind prediction to optimise system configuration and integrates the generator and servo control for constant output. The proposed wind forecasting achieves direction series prediction on the foundation of the conventional wind speed model.

6 FAQs about [Wind temperature deviation on both sides of the generator]
Does wind speed affect a photovoltaic generator?
Here I show in the real-world operation of a larger scale photovoltaic generator that increases in wind speed can lead to small but notable energy losses, reflected in the mismatch losses directly derived from the operating voltage of each module.
Does the wind turbine model comply with official datasheet?
The graph shows a very good relationship between the results of the implemented mathematical model with manufacturer data. This means that the wind turbine model under examination has a very good compliance with official datasheet. 4.2. Experimental WTPC with Fourier series interpolation
How do we measure transient temperature due to wind variations?
The transient temperatures due to slight wind variations were measured in a single cell, with a thermographic camera FLIR E60 for 40 s between the 6 images. For a better visualisation of the cooling driven by the wind, the interval of temperature was set between 35 °C and 37 °C.
Does wind direction affect PV module temperature?
It was observed that, the effects of wind flow perpendicular to the orientation of the modules varied from the impact of wind flow parallel to the PV module orientation. Hence, the varying effects of wind direction on the temperature of the modules, as well as the efficiency of the PV system.
Do low wind speeds induce thermal gradients?
Low wind speeds are sufficient to induce thermal gradients inside PV generators, modules or even inside single cells. These thermal processes are quite dynamic and variable: the simple change in wind direction suffices to change the airflow patterns and, consequently, the temperature differences Δ T.
What factors affect wind power output?
This is because, besides the wind speed, there are more important variables involved in turbine power output such as atmospheric pressure, turbulence intensity, wind direction variability, both vertical and horizontal shear, atmospheric stability, drive train temperature and so on .
