The first decision is related to the location: Greece (like the rest of Europe) is located in such a latitude that the movement on a vertical (or inclined) axis is the best choice. Horizontal axis solutions only work in different geographical areas.
After a simulation in special software (PVsyst) and experimental installations, we confirmed with data that for the Europe zone, there is increased performance when the photovoltaic cells rotate around the vertical axis

Higher output than a
horizontal axis tracker
Designed economically
The power demand curves match the output curves of the trackers. This means that when the grid has higher power consumption needs, then the tracker compensates for the difference between output and consumption.
So in practice, there is not so much need to store electricity, squeezing the cost of the investment and increasing the profits of the park
