Hi Roland,
Torqeedo specs the solar charger at 40-45W and the plug in charger at 40W. So the solar is technically faster, but it does not appear to be significantly so. As usual, voltage alone isn't enough into to compare total throughput.
But thank you for the clarification.
Fair winds,
Eric
Marina del Rey, CA
