<p>Okay looks like SciPy found a feasible solution without too much time. Now let’s review the plots.</p>

<p>So we can tell now that the battery energy doesn’t go all the way to zero. One thing to note, because we have a solar UAV the voltage is regulated differently and the C-rate doesn't apply in the same way.

Let’s look at how the solar flux varies throughout the day and how that affects the draw from the battery.</p>

<p>So maybe those solar panels actually are worth it. They seem to decrease the load on the battery considerably during the daytime.</p>
