Was thinking about your recent electric power issue and this episode had some detailed shots of the aft solar panel array. My first thought was you might be able to have sliding pv panels come out to the side while at anchor. Two 38" sliding mechanisms on Vevor cost around $80 (the arms extend out 38" more than the fixed part, but rust might be an issue) and that might allow you to have a 65"x 39" 250w panel on each side tucked away on passage and pulled out at anchor. Two panels so 500w more possible power
The other idea is replacement of the 3 pv panels (assume 250w each so 750w total). Another idea- Looking at Santander solar site. a 455w 82" x 41" Solar Ever panel runs $255 (no shipping) so 3 ($765) could produce up to 1365 w or 83% more, 615w more than assumed current 750w. There is added weight as current panels may weigh 42lbs each while Solar Ever's weight 52lbs- so total of 30 more lbs plus more windage when angled. Steering away from Bifacials due to higher cost and much more weight. You may need a new MPPT- a 60A BougeRV or HQST currently cost $175/$219 and can handle 900w solar input (2 455w panels) charging a 12v bat bank. Just an idea to get you more power via the sun vs gas or diesel elec generator. Know the prices don't reflect what might cost in Grenada. Sorry about length.
