The way some people look at the cost of MPPT, is by power gain/BTUs per watt.

Once they have the cost, they compare that cost to buying one more PV panel.
Because normally, buying more PV watts is cheaper than buying MPPT stuff.

That's how people figure out 'tracking' mounts. If it costs more than 200 or 300 more
watts of additional PV panels. It's better to buy more watts up front..
