300 Watt Solar Panels, 12V 150 Watt 2 Pack, Monocrystalline Cell High-Efficiency PV Module, Solar Panels for Homes Camping RV Battery Boat Caravan and Other Off-Grid System

Muy bueno

I used these to build a portable solar setup. I'm seeing about 260W produced from two 150W panels, so roughly 87% of their rated value on a "best effort" angling to match the sun. Not bad for the price considering I paid less than a dollar per watt.

Beware! I bought 4 panels and after installation found out 1 cell is Polycrystalline and not Monocrystalline. This especially sucks since I already finished installing them in series... Don't buy.

Nice panels. The panels come with 4 pre-drilled holes in the bottom for mounting. I added two in front and two in back, since I expect the conditions to be a big more rough. Seems to produce desired energy.

The solar panel mono , I am not fully satisfied with the product because I order 600 watts and even in a full sun I never reached 300 w connect on series The solar panel I use before mono crystalline from Renogy was much better

One of the two panels showed up broken.

Compared to pricier, lower technology 5bb 190w solar panels by GoPower being replaced due to an unfortunate incident; performance of these 10bb solar panels falls off much quicker as the solar angle of incidence decreases. When angle of incidence is within 10 degrees perpendicular, performance is comparable and these panels meet their specs, even exceeding them slightly. As for partial shading, the touted improvements of 10bb appear neglible. One 3" square corner shaded resulted in ~30% current loss with solar angle of incidence of about 80 degrees.
