Interesting thread here. Just wanted to throw in my two cents. We just bought a Lagoon
450 that had previously installed walk on panels
made by Aurunco. They failed. Iím currently replacing them with 11 panels
by Solara. Their Power M series. They are semi rigid. We will have a total of 1300W. I just got 6 of them screwed and glued today. We are using outback controllers and a few victron controllers. These will feed our large Lithium
Mastervolt system. Each different panel size needs to be kept together, so that you donít mix voltages. Each one has its own diode as well to prevent over heating
. This Solara brand appears the be the best in class and will work
well with oblique sun angles, and partial shading. They are true walk on panels with a non skid surface that actually has a prismatic effect to capture more light.
I have to say that these panels are fully encapsulated and appear to be of exceptionally high quality.
In my opinion, the glass panels are certainly cheaper, but much more fragile, and they are typically mounted in areas where windage could become a serious issue on giant frames. I do agree that the Solbian flexible panels appear to be cheap
, and obviously the cheap
Chinese stuff is not built for a marine environment
. These Solara panels are made in Germany
and so far Iím very impressed and happy with the product. They arenít cheap, but they appear to be very well engineered for the marine environment
Weíll have to see how they look in 5 years.
