Solarland® 80 Watt, 12V High-Efficiency Standard Polycrystalline Solar Panel for Off-Grid Applications (SLP080-12U)

I bought four of these panels to replace the old 42W panels on my sailboat. These were slightly smaller and rated at twice the power output as my old panels. The panels were lighter than my old ones, easy to install, and better sealed against the weather. It is winter, so I'm not getting as much power as I will when the sun gets more directly overhead, but I am getting twice as much power as I was with my old panels. The new panels look well made. Only time will tell how they hold up, but at this point, I'm very happy with them.
