Right proportions in FV system

please read this pdf:

in my experience I have seen che batteries lead calcium acid have to be charged to 15.4V and lead-antimony / selenium-acid, the 15.2V is enough (as it says lidemann)
the best solar panel is really the Amorphous or Thin Film tecnology, why in the summer the heat does not lower its performance and even in winter and rain we can give a 20% energy.
but I do not agree with lidemann about the right proportions of the various components of a PV system.
In my opinion the ideal is this:
Amorphous panel 100Wp
10A mppt regulator
120Ah-12V battery
100W inverter
With This mini-system we can use 0.24kWh / day even in December.
If we multiply by a factor X10 are:
Amorphous panels 1kWp
Mppt regulator 100A
1200AH-12V battery
1000W inverter
As written above, this system allows nor have 2.5kWh in December, and in July 5kWh.
These proportions are extremely conservative, but this save us to change the batteries for many years.
