Optimal tilt angle (southern hemisphere) = -0.41657 + (1.4216 + (0.024051 + 0.00021828)) A simple, research-backed way of calculating the optimal tilt angle of your solar panels.

All you have to do is to establish what is the optimal angle for panels based on your zip code or simply calculate it by using one of the two methods we explained above in the text. Change the results from Per year to Per day to get your average daily solar irradiance.

WebThe ideal angle for solar panels in Australia is usually equal to the latitude angle of the location of the property. Correct your compass by your magnetic declination to get true north.
