I like the sounds of the 54v panel but for my situation the lightweight semi flex panels with the sunpower cells are suited.

They are rated at 17.7v and will be wired in series

What makes them suitable for my use is they are just 3 mm thick salt water spray safe and durable enough you can walk on them , they bend 30 degrees and weigh 3.5 lbs 42" x 21" wide.

Bonus is they are 22% efficient

I have done some number crunching to see how the charge will compare to Mikes charge ratio

Mikes 1500w pv's to 10,000 wh battery = 1 to 6.6

My ratio with 200 watt PV into 750 wh in battery = 1 to 3.75

So I have close to twice the panel size ratio

In the future I will likely get two more semi flex panels as they pack together so well its of little inconvenience.
