I like the first kit;
1. Mono VS Poly panels
2. I have no need for an inverter other than a small 600Watt I hook up for DW's hot rollers; under $40 at Wal-Mart.
3. This is a plug-n-play using the highest of quality cable and waterproof connections.
Get the kit, install and THEN buy the cables at the right length you need for the p-n-p set-up.
I bought this type so I could plug in at the roof and at the batteries if I wanted.

As far as the 'practical' application, I can tell you that you'll probably realize about 8.5amps of charging current during the best part of the day if panels are flat mounted to the roof.
