If the Solbain 50W semi-flexible solar panel proves reliable and efficient, two more will be added on the bimini along with a 100W semi-flexible panel from Go Power! (http://www.defender.com/product.jsp?path=-1|328|2290044|2290050&id=2485752) which, when all installed should provide us with a peak output of 250W under ideal conditions. The advantage of using these panels is the weight reduction (total weight of approximately 7 pounds total for all four panels), ease of installation (zippered in place) and ability to integrate them into the working canvas covers without having to fabricate and expensive and weight intensive arch for installation. The trade off is they're fractionally less efficient than the hard-framed aluminum panels; they're significantly more expensive per watt; and, the longevity of operation may be less than the rigid panels.
In addition to adding solar panels next season, we also need to replace our two house batteries (AGM Lifeline 4D 255AH batteries). Between leaving them to self-discharge over the summers and then running them flat while the boat was left in the water this past summer, their capacities have been diminshed over the five-years they've been in the boat to the point where they need replacement. We're also hoping to replace the remainder of the white dome lights and the reading lights with efficient LED conversions. Our intial foray into white LED replacement resulted in light with unsatisfactory brightness. We're hoping for improvements to the light output so our halogen reading lights can be replaced, along with the incadesent dome lights.
One further project for this season will be to install a 'smart' battery monitor. We have a Victron Energy, model BMV-600 battery monitor that will be replacing the old 'Professional Mariner' battery tester.

Sounds like you've been busy ... love the idea of the flexible solar panels .. so slim!
Hi Ken & Cheryl,
Solbain panels were the culmination of the search for light weight, efficient solar options to avoid adding the weight and expense of a dedicated solar structure. Since the Cal is an older moderate displacement boat with tapered stern dimensions, keeping weight out of the ends is important for maintaining sailing performance. I had been looking at Solbain panels and Wind Traveler's experience with these made the decision easier. If the 50W panel proves to be what I expect, I'll be adding another 200W (three more panels) to finish the project. Thanks for your comments.
