3kw of solar panels is about 4hp. That's in ideal conditions.

Ideal conditions for stationary panels is typically 4-5hr per day.

107hp is about 82kw. 3kw x 4hr= 12kwh or a little less than 9 minutes at the rated power (which isn't that much)

But wait, I'll give you dollars for dougnuts that the 3000w of panels includes the official rating of all the panels. In reality you will be lucky to get half the panels in the sunlight. Seriously, look at the bottom one on the front overhang. It's aimed down at the ground. So give them a generous 50% rating and you are down to about 4.5min per day at the rated power. Assuming you push it down a hill to get it started, you've got maybe 4 miles of range per day under solar.

Hope you don't camp in a forested area. Just a single branch shading a panel can kill all of it's output.

I also like how they claim it's eco friendly because the black sides absorb heat when it's above 79F. Most RV's are hot boxes when it gets into the 80's cooling is much more important.

Why do the proponents always over promise and then look like idiots? It turns people off from viable technologies. Used appropriately, solar and batteries can do good things and you can make RV's more efficient but this is a total joke.

All those solar panels won't bring in squat. The ones on the side bring in substationally less power than rooftop ones. Even with all those, it still can't run an A/C, much less get enough power to spin the driveshaft past the torque converter.

I've wondered why RV makers don't do something more practical: Awnings on four sides with flexible solar panels on each. That would bring in a lot more electricity than slapping panels on the sides. It definitely would not move the vehicle, but would allow for 1000-1500 watts of solar at least, which won't run an A/C, but could help with a microwave or kitchen appliances.
