Two key things with solar 1, Get an MPPT regulator - makes a huge difference in charging efficiency.
2. Get the panels in direct sunlight. - even having a shadow the thickness of the boom across a 4' long panel will take away about 60% of the amps/watts you get out of it. My mizzen boom sometimes casts a small shadow on my 130W panel, and even in the Carib, it'll only put out about 3 amps @12V, then I drop the boom and it'll shoot up to over 10. Love my solar. Wish I had more of it.
