996Pilot,
Unfortunately I am unaware of a good MPPT controller that is cost effective with simply adding an extra panel.
In 2005 it made sense to go MPPT as panels were $5.50 per watt. Now they are as low as $0.28 cents per watt.
That makes MPPT viable only if the roof space has been maxed out.
Like I said - so add an extra panel - brute force. If you've got the real estate and can really find a descent panel at $0.28 a watt (that's $28 dollars for a 100 watt panel - PLEASE show us that deal right now) go for it.
Just pointing out that you cannot get as much out of existing panels with PWM as you can with MPPT -- simple.
Now PLEASE send us ALL a link to that $0.28/watt panel - PLEASE.
