Simply Unbeatable | More Power in Less Space

Maybe you have multiple wire runs of different lengths and want to cut custom lengths of PV wire and crimp on your own MC4 connectors?


Choose between 5 pairs of MC4 connectors (5 male and 5 female connectors) or 10 pairs of MC4 connectors (10 male and 10 female connectors) that can be crimped onto PV extension wire with the MC4 crimping tool.

SunPower 170W E-flex solar panels

So now I generally

don't bother hooking

up to shore power!

Thanks for all the help in planning my solar project for my boat. The two 170W flexible panels fit well on my Bimini and now I generally don't bother hooking up to shore power.  Although I haven’t had any long trips since my installation I have done a few day trips. And even with fridge, radio, plotters, autopilot and occasional radar it seems that these panels are keeping up with my usage. I did add some stiffener material to the back of the panels and attached the panels with zippers and they have survived a few 30 knot days and one night with winds gusting well over 55 knots. No damage at all and no signs of flexing problems. 

The advice and service has been great.  Thanks again.

high efficiency flexible solar panels

It made my project

work, thank you

Lyall and Katie are so knowledgeable.  I tried this project with a lesser quality panel and the project failed because it wasn't efficient enough. The SunPower® Maxeon Gen III cells are compact and simply kick out more Volts/Current than all the others on the market today.   And by using the SunPower® panel, everything was smooth and efficient.  I love my new 170W 29V 5.83A panel!!  It made my project work.   Thanks Lyall for all your knowledge in making this work.
