TopsolarSolar Panel Kit 170 Watt 12 Volt Monocrystalline Off Grid System for Homes RV Boat + 30A 12V/24V Solar Charge Controller + Solar Cables + Z-Brackets for Mounting

Installed for our outdoor shed and hooked to a deep cycle marine battery, so far working fine.

First off, for anyone wondering these are not the same panels as the 170 watt ones in the kit. They are very similar but not the exact same in a few different ways. They are easy to connect, do your research but you almost can't hook these up wrong. They are a good value for the money, especially for those of use who don't have the budget to order a whole pallet at a time. The size seems to be a little bigger than the standard 100 watt panels, but not too large thar you can't handle them by yourself. Seems to be very durable, however the plastic corners often get broken off during shipping. Would be awesome to see a pack of replacements from the manufacturer. I haven't researched these vs other panels admittedly, but seems to be pretty efficient. Two panels hooked up to a 1100 watt inverter and an upgraded solar charge controller will run 150 watts or so almost all day and night hooked up to two 12 v batteries (largest AGM from Bass Pro). I've ran TV's and wifi, grill, fans, ect...obviously depends on your setup but will charge your solar batteries and do what is needed for a good battery life.

Everything to set up power in my mower shed. Runs an LED shop light, trickle charger and phone charger easily.Dislike- doesn’t tell you in instructions NOT to have power on the panel when connecting to the controller box. It will burn it up !!

I got these because they looked like they would be the perfect panels to add to my EcoFlow Delta 2 system. I already have a 160watt EcoFlow portable panel (which is fantastic, btw), and these two are exactly what I needed to get to 500 watts.I have them hooked up in parallel (and yes, I know that in series brings in more wattage, but this helps keep everything OK even on the coldest days) and I'm a little underwhelmed at what I'm able to bring in. That said, the panels themselves feel like they are good quality (about 30 pounds each, I'd say) and they have definitely helped bring in more solar.Without dedicated testing of each panel, I can't say for sure what they're really pulling in.. but my gut tells me that each one is closer to 100 watts. Based on the price, that's kind of what I was assuming when I bought them so I don't feel that's a problem.I did appreciate that they came with everything that I'd need to install them (and a few toys that I don't use, like the charge controller). It's a pretty professional operation, and I would buy these again.So, in short, I think that these are great panels for the money. They DO work, and they feel sturdy enough to stand up to good abuse outside. I've had them pull in 50 watts of solar on RAINY days, which is fairly fantastic.

So I purchased my first solar generator with a 60-watt portable solar panel. The highest wattage output i have gotten on a blue-sky sunny day is ~40. I then upgraded to a '120 watt' portable style panel. It maxes out at about 60-80 watt. Also when it is a bit hazy sunny neither actually work at all. I purchased my new generator with 3x the capacity of my first one so I need something which could deliver a lot higher charge rate. I purchased the 200 watt panel kit (2 100w panels). I have only tried these for a short bit but they have proven they are FAR superior to the portable styles i already own. I had a mostly cloudy day trial yesterday. When the sun was mostly covered but somewhat bright i at least was getting 30-40 watts. When the sun peaked out for nearly full sun the rate jumped up to 180 watts. I'll be purchasing another set of these for sure.

I Made the mistake of not testing this till after the 30 day prime return window closed. On the initial use it too almost 2 hours in direct sunlight to start charging above 4 watts. Once it did start I could never get above 80 watts with no obstructions on a 100 watt panel, angled toward the sun and in 100% direct sunlight. At 80 watts max charge it immediately dropped to 30 when just the shadow of my hand passed over it. With an 8”x8” cloth on the corner it dropped all the way to 3 watts (basically not charging).When I contacted support they asked for videos but won’t accept the video type from my IPhone and have a small file size limit. I asked for an email address to send the videos to and was ignored. When I questioned the max 80% charge and the fact that a shadow on a very small part of the panel renders it useless they just gave me a stock response saying the efficiency depends on the amount of sunlight.Just so you understand, it was a cloudless sunny day in southern Nevada in the open so you don’t get much more sun than that.I had planned to add a second panel and now will end up buying 2 from someone else.If you choose to buy this brand, TEST IT THE DAY IT ARRIVES so you have time to return it if you have the same poor performance I got. The customer service is terrible and useless.

I was a little Leary of buying this. I mounted it on top of my motorhome. It works great. Keeps my batteries charged up full when I do not use the coach. Still maintains the batteries on cloudy days.

The performance of the solar panels are up to par and I would definitely recommend them the system works as described!
