    325+ watt splar panel smaller than 41"x65"

    We recently completed our first Off-Grid solar installation on our 2011 Winnebago View 24K RV. Unfortunately the roof on our 24 foot RV is seriously cluttered with an AC unit, 2 Fan-Tastic vent fans, refrigerator vent, HDTV antenna, Sirius satellite antenna, FM antenna, roof ladder brackets, shower skylight, and a myriad of vents which really only leaves room for one large panel or 3 smaller 100W panels. Multiple panels would have been a lot more work, expense, aerodynamic drag, and looked tacky (our panel can barely be seen behind the Winnebago "winglets"). Pictures here: https://groups.yahoo.com/neo/groups/...ums/1856159274

    I spent hours using a C.A.D. program trying to figure out a way to install a 2nd panel and concluded one large panel was our best option... Which is why I'd love to find a panel that's at LEAST 325 watts that fits into the 41"x62" space the SunPower 327W E-series or 335 / 345 X21-series panels fit. A 41"x72" panel would actually fit but that would eliminate the narrow footpath we use to get to the front of our RV's roof for washing the cabover area and transparent smoke vent lid. Definitely a tradeoff... which a 325W or larger panel would hopefully justify.

    What 325W+ panels would you recommend for these footprints?

    41"x65" (size of current Renogy 250W mono panel)

    42"x72" (maximum obstruction free roof area)

    Thanks for your manufacturer, model and vendor recommendations!

      Similar problem to mine. I can get nice big watt Sunpower panels that fit my space locally really really cheap. Problem is Positive Ground. Shouldn't use on a Vehicle...

          Great info! I never thought about the SunPower panels requiring a Positive Ground. I never even thought about that!

              What 327W E-series and 335 / 345W X21-series SunPower panels can you get? And what do they cost?

              Is there a relatively inexpensive way to use them on our 2011 Winnebago View since it has a non-metallic fiberglass roof?
