What I did
One friend has a flexible solar panel for his 30' sloop, and another has non-flexible panels mounted on his 45'. I was convinced by looking and talking with them that the non-flexible, permanent mounts are a HUGE mistake. They are very much in the way.My H25 has no generator, nor easy access to AC, so I bought a single 10W flexible panel. My battery is always fully charged... and I come back from overnight trips (running lights, anchor lights, radio, depthfinder, knotmeter) with the battery STILL fully charged. Because it's flexible, I mount it on my cabin top hatch with bungee cords, or stow it easily when it might be in the way. I SO LOVE this panel that I have thought about trading my outboard in on an electric motor, another battery, and another panel.Finally, you're looking for the best... and I was looking for the cheapest! So I searched the internet for prices. There is a wide range. In the end, I bought a factory second for $99. It has some cosmetic flaws, but works fine. Because it was a second, it came without a guarantee (I hadn't expected that... and gulped nervously... but it works great.)Do a search for "solar panel flexible" and you'll come with a number of sites. Good luck.Rick
