From the vast amount of knowledge out there could someone advise me on the best relatively small solar panel which will work in low light as well as good sunshine for mounting on a pole attached to the pushpit of my Sadler 26 ( has two 85amp hour batteries). My mooring is on an unserviced pontoon. I look forward to your advice, thanks, Kevin
 
Any reason that you can't mount them on the coach roof? We have a Sadler 32, I know its a bit bigger but we get two semi flexible panels on, one 60w and the other 69w. They tolerate feet too
 
We fitted one of these new flexible, efficient panels to the curved coachroof of our Trapper 500 (27ft). This is 30w, but about the same size as the older 10w models - very high output for its size. Its tough enough that you can stand on it. The panel is simply glued on, and goes through a dual charge controller so we can control how much charge it puts into our house (110Ah) and starter (90Ah) battery. Works a treat - our boat stays on a swinging mooring but our batteries are always topped up.

Thanks gents, I did not want to put it on the coach roof as I have all my lines running back to the cockpit plus the vang, plus vents and also thought the shadow cast from the boom and stack pack would diffuse the sunlight, hence the idea of a pole, bracket and multi positioning ability for the panel which can therefore be a rigidly constructed unit. However you all seem to be happy with a 30watt so no need for me to go higher. I generally don't leave much switched on when I leave he boat so it's purely to top up the batteries especially in the winter. Cheers
