Federal Tax Credits

Federal Tax Credits

Did you know there are Federal 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  2021 the Federal Tax Credit is currently 26% of the total cost to put your solar system in place (panels, controller, wiring, batteries, labor etc.) 

After filing & receiving your Federal Tax Credit you could save a lot on your system cost.

Read more details on our Solar Tax Credits page.

1/1/21 - UPDATE: The renewable energy tax credits have been extended as part of a $1.4 trillion federal spending package.  This will keep it at 26% until the end of 2023.

Custom teardrop trailer

1x 170W

Many of our customers have RV's, campers, tiny homes etc.  Bill recently installed 1x170W SunPower E-flex solar panel on his custom teardrop trailer.  With his family they're planning a lot of roadtrips.  The flex panels are lightweight & have a low profile which means less drag and more MPG on the road!

"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. The advice and service has been great.  Thanks again.

"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.

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
