There seems to be many experiments done to see how the angle of the solar panel effects the performance. Conclusions are similar, stating the relationship between optimum tilt angle and the geographic latitude was confirmed. The tilt angles always differed drastically between winter and summer months. The swing angle of the sun is also a very important parameter for calculating the maximum power of that time of the day. The sun is where all the crazy math comes in, I don't think I'll have have to do these equations because they are already done for me but I will see/give examples. Now, both of these experiments were done at different locations, the only difference of my experiment will be the size of the solar panels and I will have different results since my latitude/longitude location is different. It will also be conducted during the winter months instead of the summer. Methods and materials will not be as dramatic as the other experiments, one actually used a "sun simulator" which I will be using the actually sun.
Here is an example of equations to determine angles of the sun and solar panel (I am not sure what this means yet but I will try my best to go the extra mile!)
λ = ∠EAB − ∠DAB as ∠EAB = 90◦
∠BAC = 180◦ − (φ + αs), ∠DAB = 180◦ − ∠BAC (winter situation)
I am not able to use the graphs on the website due to copy right but here is an example of what my graph could look like.
