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

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

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.

Simply put, these panels are lightweight but solid. So far, I couldn't have asked for more under the real-world conditions present out here. I've been able to reliably get 80-90W out of the tested panel, and I'd consider that excellent results for the local conditions and environment.I haven't experienced any of the delamination issues reported by others, but I suspect such issues are a result of the heating/cooling cycles combined with exposure to water. As per the product description, the connectors and junction box are what is listed with an IP65 rating. The description does not state that the panel or the complete assembly are! In other words, be ready to bring the panels out of the elements when inclement weather approaches or things become too extreme.Edit: 2 months laterWell, it seems that one of the panels is starting to develop ripples in the surface. Nothing has delaminated, but it does suggest an issue probably does exist in the manufacturing process. Whether this is due to contaminants in the plastic or an uneven thickness or something else, only the plant engineers could say. However, under continued use at extended temperatures (especially if not kept flat), the issue does pose a real chance that the panel could eventually delaminate.All in all, the price and quality per watt of output are still very decent. However, you may end up with a few that are less than perfect in exchange.

These panels are fantastic. You should NEVER expect to actually get 130W out of a single panel unless you are on the equator and have perfect sunlight conditions. In actuality an array of 4 of these (two in series in parallel) provides 645 W maximum possible power (because Watts = Amperage x Voltage, not just a word on a panel). No I'm not getting that much out of mine because a) it's winter and b) I'm in Ohio, not on the equator. What I *am* getting is 100W on a CLOUDY DAY and ~350W on a bright sunny day (that's with an array of four, again). THIS IS PERFECTLY REASONABLE.Feel free to do the math yourselves if you wish.

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.

First off the shipping package is one of the best that I have seen. But the panels are not up to par. Each panel is working at 80 to 83 watts, both panels are working at 150 to 153 watts. Each panel has a rating of 130 watts so the panels are not preforming like advertised. I gave 3 stars because of the shipping package. I'll keep looking for panels that preform the way they are advertised too.Back how checking these panels at peak time and just weak as in the morning. 155 watts laying flat like the roof panels. Very disappointing as the Eco-Worthy is supposed to be 130 watts per panel. Two panels = 260 watts getting 155 watts, that's only working at 60% that is bad. Don't think I'm going to purchase these panels again. Sad days!

Excellent value. Panels working great so far
