I got this today via email and thought it looked interesting for boat use. The 4 panels (approx 40" x 27") might fit well as a FB or cockpit cover.

I question the efficiency of the charge controller as I've heard Maximum Power Point Tracking (MPPT) is the way to go and this one is Pulse Width Modulated (PWM). Does it matter? This setup even comes with a 2000W pure sine wave inverter, albeit a Xantrex model. The charge controller is also a Xantrex product. The Grape Solar site claims 17.4% efficiency on each 100W PV panel. How does that compare to other widely used marine panels?
Here's the spec sheet.
At $1100, this looked like a fairly capable package, but would love to hear from others with solar experience.
