Hi,
Quality panels are under $1.00 per watt.
The Aims is a bottom of the barrel inverter with no ability to be repaired post warranty. Xantrex makes a model that is better with larger capacity for $355.00
I think you mean a Xantrex charge controller. It is not MPPT and could be replaced by an Ecoworthy for $30.00.
I think you should find a different firm.
They'll probably have a better luck with independent RV installers. Most "firms" are dealing with shore homes and have no clue as to RV installs. As SMK noted, one should keep an eye on that installer guy, be it firm or no firm. Or they would attach 40lb panel to EPDM roof with a sticky tape and no screws. They do this, no kidding.
Yes, Xantrex are better inverters. I'm confused though, what model they are selling for $355: 600W or 1200W.
Yes, I think they meant Xantrex/Tracer C35. With all due respect, Ecoworthy will barely cut it for 300W array. Xantrex C35 is a fine controller for this application, and $275 with display and "breakers" is reasonable, just make sure that installers won't skip on $20 remote temperature sensor.
Good +200W 24V panels are indeed cheap, but 100W panels cost more per watt. "Quality" panels are rare this days, with influx of unknown quality products of Chinese origin. I agree that digging through this big pile of cr-ap one could find 100W panels for $100-120 :) ...
I don't think the OP need to go for big +200W panels that would in turn necessitate $$$ MPPT controller. Ecoworthy MPPT a little small for this array. It costs $100, not $30.
$1600 for 300W solar in parts alone, jeez... It cost me less to buy 500W and quite decent MPPT controller 2 years ago when prices were higher. My inverter is a cheap 175W, though.
