This is not necessarily a disadvantage. If you have a contract with pricing based on the 15-minute intervals of the day-ahead market ("dynamischer Stromtarif"), then the electricity price spikes in the morning and evening. Typically with such a contract, you also get this higher price for injecting power back into the grid. And the price will almost always be lower than a traditional contract outside of these spikes.
A vertically oriented panel is also ideal for this scenario, because the sun will be low above the horizon when the panel is producing power in the morning.
edit: after looking into a bit more, it seems in Germany you may not actually get dynamic feed-in pricing. Too bad. I assumed that this was the case, because it works like that here in Belgium.
