Perfect for those RV's that want long term off grid camping systems. This is about what it becomes viable to 510 watts is a sweet spot in the power/ price range and can render those generators useless in a hurry. Lights, Phones, computer, and T.V. will be no match. With Lithium batteries, refrigerators, tools, the microwave or hair drier will be at your every whim, maybe a small air conditioner a few hours a day. Perfect for a medium size RV or small cabin.

Why is this kit better than the smaller mail order solar kits?
There are lots of reasons on a system this powerful. It's just too hard to mount and wire enough small panels to generate 510 Watts.
Aside from that there's the Better price, better performance, better quality with easier installation. Bigger, UL rated industrial grade panels are much better and less expensive but are too big to ship economically. In order to combat this, mail order kits use multiple small, more expensive, low production, low power, lower quality panels, then mate them to a low cost, low performance PWM charge controller. This means lots of mounting holes in your roof and complicated, spaghetti noodled wires if you want real power. There are lots of disadvantages to mail order system in terms of power generated, line loss and complicated installation. Big panels and MPPT's are the only way to go, cheaper, easier and higher performing.
