Hello
I have a solar cell installation on a car for my flat
driving cycle UDDS(FTP 75) As we want to get my wind blowing over the solar cell is considered to be on the increase
I analyzed the system? What is the best way to analyze?
Amir,
You have not specified exactly what is the domain in which you wish to "analyze" the system - steady performance, dynamic performance, economic, or environmental ?
Assuming that it is the basic steady state analysis that you imply, there are analytic procedures and formulae involving NOCT (Normal Operating Cell Temperature) and ambient wind, that you could use.
Should be easy to locate on the internet - you can easily do a search and then decide about the way you wish to analyse the system.

Dear Amir,
i could not understand your question properly. but as it is related to solar cell performance and blowing wind conditions so i am mentioning some results related to it.
Standard Test Condition for the performance of Solar Cell / PV modules is-
1.specifies a cell temperature of 25°C
2. irradiance of 1000 W/m2
3.air mass 1.5 (AM1.5).
the efficiency of solar cell will be maximum when it is under Standard Test Condition (STC) but it is to keep in mind that with increase in solar intensity, the temperature also increases (above 250C) which reduces the output of solar cell ie. it reduces the efficiency of solar cell. Some times, blowing wind reduces cell temperature which improves cell efficiency.

Thank you
Think wind speed for a solar cell as the driving cycle (UDDS or FTP 75) is now want to get the cooling solar cells for solar cells to get real-time
Below been the driving cycle

It is quite difficult to calculate accurately the temperature of a solar cell in a real world application. To keep your cells cooler, you could put a sheet of IR reflective glass over them, but not in contact - leave a gap of a few centimeters for cooling air to flow. I don't believe that in any tropical or sub-tropical country the temperature of a horizontal solar panel near the ground at midday would be anywhere near 25C. I would have thought 70 or 80C would be nearer, and the output voltage of the panel would suffer. Have you measured the temperature of real panels on a car roof at midday in Iran? But don't spend a lot of time trying to calculate power from first principles - I suggest you perform experiments, and then producesimple practical formulae for panel performance based on the experimental results.
tnx
what formula(produce simple)???
I suppose I got here fast car on a solar cell is the same wind speed.
Driving cycle======wind speed for cell pothovoltaic
And ambient temperature of 25 C.
؟؟؟؟؟؟؟؟؟؟؟؟؟؟؟؟؟؟؟؟؟؟؟؟؟؟؟؟؟؟؟؟؟؟؟؟؟
Or in other words,
What the wind speed have effect on output or efficiency of the system?
