I can now cruise in comfort 8 months of the year!

I was satisfied with the solar panel system I purchased from Sun Powered Yachts. Lyall provided great advice and the systems included cabling, connectors, controllers, and circuit breakers plus guidance for the DIY installer.  I also added 12V air conditioning, new lithium and a 12V watermaker.

 

I can confidently say the installed systems are up to the task and I can now cruise in comfort eight months of the year.

Our gen run time has
been cut nearly 50%

The solar is working out great! Yesterday in the Exumas I saw 39A @24vdc from the 3x410W panels.  Each panel was around 400 Watts which really exceeded my expectations.  Our gen run time has been cut nearly 50% and the peace of mind leaving the boat at anchor for day trips is priceless.  Thanks again for all your help with our system.

On sunny days I
can make a lot of ice!

I've done two solar projects with Lyall at Sun Powered Yachts on the same boat. The first was with 2x flexible panels mounted on the Bimini with a total of about 340Watts.  The second was 3x 410Watt fixed frame panels, with all the charge controllers, circuit breakers and accessories needed. Lyall helped me design and pick all the parts and pieces to get that all working.

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.

Terrific customer service, patient, always responsive

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.
