Thanks for you feedback, I also connected with Lewster and I am now in a much better position to understand what I'm faced with as I evaluate my options. Lewster recommends upgrading the standard wiring as it will basically support a 100 watt solar panel but if I decide to go up from that I should consider the bigger gauge wire.

If possible, would you please post a photo of the solar panels after installation. I'm interested in seeing how they are positioned. Thanks

Here is the installation photos. They did a great job at the dealership and the panels are riveted to the frame and the the alumn skin with expansion anchors. This is the preferred mounting method by Airstream.

Non shrink seal prevents the weather from penetrating the exterior.

200 watts (2-100watt zamp solar class A monochrystaline silicon panels mounted on the roof with a 30 amp 5 phase digital PWM solar charge controller.

12.8 amps per hour approximately.

Not to nit- pick but depending on the way you park in the sun, you are going to get massive shadows from your a/c unit on the panels which will affect your charging ability.

Fully understood. I know someone who had their portable solar panels stolen as they are set on the ground. And to save me the time and effort of set up portables, this solution worked the best for me. Majority of the time my International will be parked on the project site as my architectural office. No shadows will be a concern there.

Many other mounting techniques exist to NOT put holes in your roof and NOT position your panels where they will get shaded. I hope that you get the performance you anticipate from your system.

They did am awesome job preventing any leaks with Airstream recommendations for mounting and sealing the connections.

I don't see a problem with my panel locations for I will be in non shaded construction sites majority of the time.
This will be my architectural mobile office and once in a while on recreation at open rv parks.

I am late to the party here, but the shading everyone is referring to is from the A/C unit as shown in your picture not from trees or other buildings.

Very true. Narrower 100 watt panels could have been placed further forward so that the panels never saw any shading.

Experience and the use of the right components teaches one the optimal placement for the best exposure. Anyone can install panels on a roof. Not everyone can do it for maximum output.

I have two factory installed solar panels on my roof. They are hard wired and physically mounted on my roof to the structure.they use non hardening sealant approved by airstream. The two panels sit side to side the width of my airstream and directly behind the air condotioner. We have been boon docking two times and we have run the tv, refrigerator, water heater, DVD player and for half the day on a sunny day we did not run out of juice. Of course we went to bed at 10pm. But next morning we woke at 7am and I check the meter and my batteries were 3/4 charged.

We had our 5 iPhones charging that day and tv running and still
Did not run out.

Works well until probably a less sunny day.

The Zamp solar airstream package works great. I had the factory install it for I did not want to void the warranty.

Gary,

Could you elaborate a bit on exactly what a ' 5 phase digital PWM solar charge controller' actually does. That's a new description that I am not familiar with. The '5 phase' is what's throwing me a bit.

Thanks!
