MPPT solar battery charger

Hi iw,
I'm impressed of your work.
I played once with mppt converters and i know how crazy is.
the attachments show dc simulation of 21V@8A photovoltaic. May be will be useful for you. I have dozens simulations of buck, boost and sepic converters, but i didn't finish the work because the 'client' give up. Now i have 3kg prototype but no panel to play
Allow me to ask you what mppt algorithm you use ?
Some of them are:
* perturb and observe (P&O - sign dP)
* incremental conductance (dP/dV=0)
* constant voltage or current (CV,CI)

May be i'm too lazy to read all your code and find out, sorry.

I suggest reading of this:

It helps me a lot, amazing study.
