Solar Panels and Solar Radiation Flux Density Help - Very Confused

[Steve4Physics]

Thank you very much for your reply and for your advice, I admit I will probably use your statement. It is a question my physics tutor sent to me in a quantum physics revision package of questions, but I had not come across a homogenous problem to this before, at least not within the context. If you like, once I have feeback from them I can inform you of the angle demanded by the question. Thank you again 👍😁

You are welcome. Yes, it would be interesting to learn what the intended angle actually is!
