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.)

SunPower Advantages
Beneteau Figaro 3
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.
Outremer 51'
4x 100W
Archer is home to Seth, Elizabeth & their 3 boys as they sail around the world. They are currently in French Polynesia and bound for New Zealand. They added 4x100W to their existing array and lay them on the tramp when on anchor. Check their website www.the-sailing-family.com
Amel Super Maramu
5x 100W
Grab your January issue of SAIL magazine to read the full article on Kelly's install aboard her Amel Super Maramu. 5x 100W flex panels attached with LOXX fasteners on the bimini. Each panel is wired to their own Genasun boost controller to charge a 24V battery bank.
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.

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.
