Simply Unbeatable | More Power in Less Space

170 Watt
SunPower® 170W E-flex solar panel - spec sheet
 
The 170Watt flexible panel is the newest product in the E-flex Series and is made with SunPower® 25% efficiency Maxeon™ Gen III prime back contact cells. 
 
This is the largest flexible solar panel available with SunPower® Maxeon™ cells, all other OEM manufacturers are restricted by SunPower to making a flex panel no greater than 150W. 
 
SunPower® flexible panels deliver the highest power output and the highest charging capacity in their product class - more power in less space.  SunPower® panels are constructed with top-grade, lightweight polymer materials, allowing for easy transport, installation and panel flexing up to 30 degrees. 
 
How much power will I get? With a 12V system an estimated daily yield for a single 170W panel is potentially around 56-57 amp hours.
 
Which MPPT controller do I need? With a 12V system pair a single 170W panel with a Victron 75|15, pair 2x170W panels with a Victron 100|30

*Solar panel tariff: Despite SunPower being granted an exclusion from the solar panel tariff on imported solar panels to the USA this was for certain size panels.  The 170W panel is still subject to a tariff as it falls in the bracket of panels sized from 120W-320W.  The tariff has already been included in the retail price.

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.

The process of researching a solar solution for my Beneteau 41 was simplified & clearly understood once I discovered Sun Powered Yachts.  Terrific customer service, patient, always responsive with guidance and products that just work. Being a novice at setting up a solar system, I had many questions along the way, and the team at Sun Powered Yachts were always there to answers my questions and provide support.
