Roger:
When I installed my Thoosa 9000. I already had two Siemens 75 watt panels for the 12 volt house system. I bought two more Siemens (now Shell) 75 watt panels and came up with a switching system so that I could configure the panels to either charge the 48 volt motor bank or the 12 volt house bank. Then I found a 60 watt 48 volt Kanaka panel for about $250 (I bought two) which simplified things immensely when charging the motor bank. I installed one Kanaka 48 volt panel on the boat last year along with two 75 watters for the 12 volt house bank. This year to get in the boat in the water faster I only installed the one 48 volt and one 12 volt 75 watt panel while I came up with a mounting scheme for the other two panels. But, I found that my needs are being met by the two panels alone. Sometimes less is more. You might try a 48 volt panel and downconvert it via a dc to dc converter to charge your 36 volt bank.

What is the latest technology for solar panels suitable for marine electric drives. This area seems to be changing quickly and the types and costs are all over the place. Anyone with experience on this and can offer some advice? I have a 36v system and really want to keep the installation light.
