<p>Thank you Theodoros for you reply.</p>
<p>It was about standard sized solar panels on a hyperbolic paraboloid.</p>

<p>In the end I made the following approximations:</p>

<div class="O1">•Half of daytime (as it is symmetrical towards N-S axis)</div>

<p>Would the panel be in a constant angle to the sun rays throughout the day?</p>
<p></p>
<p>I really don't know a lot about rotating panels and their operative characteristics, but if you could assume that the mechanism is able to work in such a way that the panel always retains a (optimum) angle to the incoming solar radiation then the problem really becomes a series of hourly solar radiation simulations with that specific tilt/azimuth.</p>

<p>Thank you djordje.</p>
<p>Indeed I am aware that it is only for fixed tilt-azimuth PV systems.</p>
<p>However, would you have any suggestions of how to make the addition of the yearly energy output of the same panel at different orientations throughout the day, following the sun path? To make it not too complicated, not by adjusting the tilt and azimuth simultaneously, but only the tilt.</p>
