Did you know there are Solar Tax Credits that you could take advantage of for going solar on your boat?  Yes, your boat!   In the USA there are both Federal & State Tax Credits and in 2019 the Federal Tax Credit is currently 30% of the total cost to put your solar system in place (panels, controller, wiring, batteries etc.)  Read more details on our Solar Tax Credits page.

Disconnect From The Dock

In adding SunPower® E-Flex panels to your yacht you have the ability to disconnect from the dock.  Why not extend your time on the water & explore farther and for longer.  Read a blog post from 'Kaimana' on how Scott & Melissa added solar extending their cruising range to 8 months without plugging into shore power!  Savor the silence on your yacht by running your engine less to power your needs aboard.  Less engine hours equals less engine maintenance & who wants to hear that noisy engine anyways?  Here's a few installs of SunPower E-flex solar panels by our customers:

1x 110W

Charlie at NAOS Yachts ocean tested a SunPower 110W aboard his foiling Figaro3 on the TransPac 2019.  Needless to say it was a wet and bumpy ride from LA-Hawaii & the 110W powered all their items on the 2,200NM crossing.  Read our blog post for more details.

Harry is cruising the remote islands of French Polynesia with over 2,380W (2.38kW) of high efficiency SunPower flex panels aboard his Alibi 54'.  With few options for plugging into shore power he can really disconnect from the dock!

6x 170W

Dirk installed 6x 170W SunPower flexible solar panels on his bimini to charge a 48V battery bank and power his Elco EP-20 electric outboard.  He's now quietly cruising the lakes all day and returning to the dock with full batteries.

Silent power

Solar panel systems burn zero fuel and have no moving parts. They are clean and silent, producing no atmospheric emissions or greenhouse gases that are harmful to the earth.  Enjoy those quiet anchorages with no more noisy engine/generator running just to charge your batteries.

Easy install

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.

SunPower Cell Technology Virtually

Eliminates 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
