ECO-WORTHY Waterproof Monocrystalline Lightweight Solar Panel 2pcs 130 Watt (260W) Flexible Solar Panels for RV,Curved Surfaces,Roofs,Cabin,Boats

I purchased a set from Ecoworthy that included two of these panels and the solar controller & cables. I then bought this set to add extra panels to the project. The technology is a little dated, but the value is good and they work as advertised. I would purchase again.

Works way better than my $499 Blutti 200 watt four panel solar panel. This 130 watt solar panel, I like how light it is and only one panel verse four panels. I live in Hawaii and have been getting 104-105 watts on sunny. Averaging about 80/90+ some clouds. When clouds completely block the sun it drops to 27-30 watts. I have it tied down on some school desk and chairs, a wooden plank under the pane to angle it slightly and keep it from flexing or dipping. Seems to hold up well in the rain and strong trade winds just flow under and above thin panel cuts through the wind have not seen it try to fly away… yet…I put some black electrical tape on the plastic rectangle box where the wires connect to the panels just in case but seems like the inside connections is sealed under some white hardened goopy glue tile sealant like substance in the plastic box.

I got the pair for my RV. On a perfectly clear, hot, southern California day, and the panels pointed in the suns general direction, I was getting about 160w (total) into my Jackery 2000 Pro. I'm sure efficiency would increase if they were angled better. With my current setup, I could add another 130w or higher panel in the future, which will happen eventually.I'm actually fine with 160+ watts for now, as that will still charge the Jackery with the 90 watts of draw I have on it throughout the day.

Get it! Works great for over a year. I will get another one for winter season to run my heater

Edit after 1 month: my 3 panels are still working fine, and given the better angle I get in the winter (vertical mount), I've briefly hit 364 Watts at peak sun (~121 watts per panel). I might have some small benefit from ground reflections, but def happy with the performance so far.I've had three of these in series running for a few days, and achieved a peak wattage of 330 watts (110 watts per panel). My setup angle is not ideal (south facing 90 degree vertical orientation), so achieving above 90 watts/panel was unexpected, much less 110 watts.For the reviews not achieving those numbers, there are a number of factors that could affect wattage: what kind of charge controller being used (MPPT is much better than PWM- I use a Victron MPPT controller), your battery voltage vs. array voltage, panel orientation, whether your panel is thermally stressed (can heat up significantly if mounted on an insulating surface) , weather, etc. As a general rule, panels in series will give you better efficiency: lower current per wattage = lower resistance losses. (Power=Current^2 * Resistance). You also might not get the full potential of your panel if you're running a single panel into your charge controller, especially if your panel's max power voltage isn't much higher than your battery voltage.As for durability, I can't say for sure yet, but I've had the panels mounted for a few weeks (prior to completing the rest of my electrical system) tied to porch railings by the grommets, and they've flexed and jostled quite a bit during very windy days. While having an open back helps with thermal regulation, I don't think it's healthy to have the panels flex so much in my setup; I'm looking for better mounting solutions, but so far they've held up.

I know that solar panels don't put out the rated power except under the most ideal conditions, however, I routinely only pull in less than 60w from these panels.....which is worse than the old 100w panels that I thought I was 'upgrading' from. Disappointing.

Performance was excellent when tilting at between 40-42’ in Southern California, even in November to March

Beware of PET panels.This was my third time purchasing PET backed solar panels on Amazon and they don't last. It's been 6 months and 50% performance loss. Bad investment
