First of all, I don't have arduino and I didn't use it before but I'm planning to buy it to start my master thesis for some local area.
As I watched videos from youtube with arduino things can be done. I need to monitor irradiance of the sun (W/m2) and voltage- current of the solar cell with a tracking system and also data can be saved by the system from readings in my hard drive. Is this system can happen or should I try something else? I need opinions and guide.
Voltage-Current and tracking system for this I found videos people who used arduino. But, I couldn't find anything for irradiance in detail and save the data. Also with one arduino these things are possible? Because, All were different videos and one use tracking and other use monitoring voltage-current.

The photodiode or solar cell open circuit voltage doesn't mean anything.
Erm, it may not mean anything to you, but this section is Science and measurement and this question appears to be about characterizing PV cells so I'd be less dissmissive.

I can try to make that pyranometer but I codultn understand how to connect something. It says different options to save data but those things mean more money to giveto this system. Is there a way to connect this system to arduino?
But those diode and other things from website they gave. I cant buy cos Im in the Turkey and shipping cost is so high.

My comment was about measuring solar irradiance, for which purpose the open circuit voltage of a PV cell is irrelevant.
Is there a way to connect this system to arduino?
Figure 3 of the first link in reply #1 has a simple circuit with a photodiode/phototransistor connected to a resistor. The junction labeled "output" is intended to be connected to an analog input of an Arduino or other recording device.

thank you. I guess I figured it out but when I start building the system, I will need help again for resistor,etc.
