I am working on a solar engineering project where I am recording voltages, currents and solar radiation of various components. I need to be able to leave the arduino on the roof of my building during the day and then compile the data. Is there any way to automatically store the recorded data and view it once connecting to my computer again or would I have to connect via bluetooth?
Log via Serial, log to SD… among others.
I apologize but i'm new to arduino. How would I log via serial monitor. I do not have a sd module so that cant be an option.

Store on local SD and download at leisure via WiFi, Ethernet, USB cable..... Bluetooth is merely the simplest, cheapest and most convenient option.
The idea is exactly the same as BT… you send the data via cable to your preferred logging device, or combine both…
Log to memory or SD, then as needed, dump that data to your BT, SERIAL, ETHERNET connection for off-node processing.
Many ways of doing this
In a similar application I have a Arduino nano collecting sensor data which is connected via USB to a laptop (under a cover) which saves the serial monitor data to a file on disk
to transfer the data I can
- copy the file to a USB stick
- run an FTP server on the laptop and remote connect to collect the data
edit: another outside project I have is based on a Things UNO where sensor data is transferred using LoraWAN to the myDevices/cayenne desktop for graphical display
If your Arduino does not have an SD card, then you can log the serial output (which would normally go to the serial monitor) to one, using the Sparkfun OpenLog.
Cheap, reliable and easy to connect! A couple of different versions exist.

+1 @jremington for OpenLog.
No software changes - if it prints what you want to the serial monitor, OpenLog just Hoovers all that right up.
You do have to go and get the SD chip yourself, but in #1 you planned to do that, so mebbe leave the WiFi or other way to not have to visit the roof to version N + 1.
