SunPower® E-Flex Installs

SunPower flexible solar panels on RV

Winnebago View

6x 110W

Many of our customers have RV's, campers, tiny homes etc.  Frank recently installed 6x110W SunPower E-flex solar panels on his Class C Winnebago View.  With his young family they plan a summer of fun adventures with no more noisy generator upsetting the neighbors.  Also the flex panels are lightweight & have a low profile which means less drag and more MPG on the road!

The simple and easy installation of SunPower® E-Flex panels on your bimini, dodger, or deck, will reduce costs of adding an expensive davit or custom racking and mounting solution for traditional large & heavy fixed  frame solar panels.

Highest quality

Incredibly reliable and easy to maintain. With no moving parts, visual checks and servicing easily keep systems operating. Solar panels are robust & durable with a junction box designed with a high level of protection from dust & water ingress.

"It made my project

work, thank you..." - Robert

"I tried this project with a lesser quality panel and the project failed because it wasn't efficient enough. I love my new 170W SunPower panel!!  It made my project work.   Thanks Lyall & Katie for all your knowledge in making this work...." - Robert


A bit of a flashback to an interview that Katie did with Ben at the Pacific BoatShow for Episode 10 of 'Out The Gate', a podcast about sailing in the Bay Area.  Read our news post for more details and be sure to check out Ben's 'Out The Gate' podcast for more recent episodes.

SunPower Eliminates

85% of Solar Cell Failures

Cell failures are designed out with SunPower

With a commitment to innovation and continued R&D  SunPower has designed a solar cell that eliminates 85% of the reasons a conventional cell fails.

The image shows that conventional solar cells lose power over time & fail because of corrosion (45.3%) and breakage (40.7%).

What is a conventional solar cell?

A conventional solar cell is easily recognized by it's thin metal lines across the front of the active solar surface.  This is usually a thin aluminum paste which is porous and easily corrodes over time.

SunPower cells have a thick copper foundation which adds strength and is almost impervious to corrosion.  By having this copper 'back contact' it is protected from any moisture ingress and the effects of thermal cycling (daily temperature swings from day/night) are reduced.   

Breakages are prevented with SunPower's thick, robust inter-connect tabs.  These form the connection between each solar cell and allow for expansion/contraction and a level of redundancy with three points of contact.  Lose just one of the narrow metal ribbons on a conventional cell and the whole cell fails.

Reasons why conventional solar cells fail
