About 6 months ago a new chassis batteries 5 WATT solar panel was installed, by Newmar factory techs. Go to 5 WATT Chassis Batteries Solar Panel - iRV2.com RV Photo Gallery
to see the new solar panel from the top. Notice the new panel is quite a bit smaller that the original. I guess technology improvements can keep the output the same while making the panel smaller. Go to Chassis Batteries 5 Watt Solar Panel Side View - iRV2.com RV Photo Gallery
to see another change. The original panel sat flat on the roof. The new panel is not only smaller, but sits above the roof by about 1 inch.
