Not all Eco-Drive movements are the same. Some charge faster than others and some have increased power reserve over others. Typically, the lowest power reserve Eco-Drive movement will have 6 months (180 days) total power reserve, and some like the U700 ana-digi module used in the Promaster SST series will have a power reserve of 7 years.
also, it is important to note that there are different grades of Eco-Drive movements. For example, the H500 module is the most basic Eco-Drive chronograph module while the E210 used in the Calibre 2100 is the most complex ECO-Drive movement to date (294+ parts, hand assembled, 11 jewels, mechanically actuated 12 hour chronograph with instant hands flyback reset). Other higher grade Eco-Drive movements are the radio controlled U600/U680 Ana-digis and the H610 world time radio controlled used in the Chrono-Time AT series, JDM Attesas, Promaster Sky, etc.
The G910 caliber is a high end Eco-Drive movement with multiple complications, minute repeater and a 9 month power reserve. It is currently used exclusively in the Citizen Signature Collection Grand Complication watches.
So as you can see, there are marked differences between low end and high end Eco-Drive movements. The only thing common to all of them is the use of solar power cells and a rechargable battery to store light energy. But beyond that, there are differences to be sure.
I am sure the same can be said of Casio solar movements with low end and high end calibers sharing the same solar technology but vastly different from each other.
