Customer Reviews
Overall rating: 4.9 / 5 from 363 reviews.
Skeptical about $200 for two 200W panels (BOGO deal), I rolled the dice and ordered two sets (four panels total). They were promptly shipped via FedEx and arrived just a few days later in fine shape. So far, I'm pleased with the build quality and power output. They appear to be the same design and build quality as other better-known brands such as the Renogy 200W flexible panels.
I purchased two of these panels as my intro into solar. They have performed as advertised. I plan to add additional components from werachy to expand my setup.

I bought a total of 12 panels from you and have them on my old cabin with a 1200 hr battery bank and a 5000 watt inverter and use it to power the cabin and also trenched a solar power lead to my resident garage where I have all my battery charging station set up so am using it on a constant but also have enough to get me by in emergency situations!! I have room for that much more if needed in future!! Like it!!
400W (100W*4PC) Solar Panels [Special Offer: Free MPPT Controller]
Had the RV out for about a week now after install and everything has been great!
have my system the body that it needed 👍👍
I have 4 200watt bifacial Werchtay panels. I really like their look. I have only had them wired up since the first part of December so I have yet to see haw well they work in full sun conditions. I have seen them give 485 watts in partial sunny conditions. So far I am impressed with them.

A nice panel used c outside
200W Monocrystalline Solar Panel [Special Offer: Free MPPT Controller]
This is a very nice panel, the packaging was good, and the board was in good condition. I got about 165 watts peak in my 3:30 pm test, but I think it would be better at noon. The aluminum frame seems strong enough and helps keep the weight down. My main purpose for using this panel is to charge a portable battery pack with a built-in MPPT charge controller when camping or in an emergency or extended power outage, and I think it does a good job of that. I would probably buy this panel again.
I have purchased 3 of these solar panels for my RV and have been using them for about 2 months. According to my charge controller, this basically gives me enough power to run some fans, lights, a water pump, a laptop, and a bluetooth speaker when the sun is high in the middle of the day in Florida. I just purchased my 4th one because the price was good. Haven't installed it yet. I was very happy with the shipping time and packaging. I repurposed 2x4' foam blocks as insulation for the RV. These panels seem to be very structurally sound.

First, I’m kicking myself for not buying more since there’s an extra 15% off for first-time orders! Second, I was truly impressed by the packaging! The solar panels arrived in perfect condition, securely packed with thick cardboard and protective foam, ensuring every corner was safeguarded. I was genuinely touched by the attention to detail from Werchtay. The installation process was straightforward. After testing the panels, I can confidently say the performance is outstanding. They generate power efficiently, and I love knowing I’m making a sustainable choice for my energy needs. Join the solar revolution and enjoy savings—get your panels while the offer lasts!
400W (100W*4PC) Solar Panels [Special Offer: Free MPPT Controller]
Especially satisfied, the price is very affordable, bought four, value for money, put one in the front yard and the backyard respectively, put one outside, ready to put another one near the garage. Passed the physical picture of the installation, especially beautiful, illuminated my entire yard, super like, this solar light really do not need to hesitate, super value, buy it is the most correct decision I have made recently, with it, the atmosphere of the home is super beautiful, and the children can play in the compound at night, and do not have to worry about the electricity bill at all. I truly recommend it to everyone.
I recently upgraded my outdoor living space by adding some lights for the evenings in my yard. The packaging came with clear instructions, and I was able to place them exactly where I wanted them for the best lighting. The design is sleek and modern, and during the day, it looks understated and elegant. At night, they emit a warm glow that creates a cozy atmosphere, perfect for outdoor dinners and late night chats with friends. The soft light isn't too harsh, perfect for relaxing after a long day. They charge efficiently during the day and provide 8-10 hours of good light at night. The automatic switch is a great added feature that saves me the hassle of turning them on and off. These solar lights have helped me save money on my electricity bill. No more plugging and unplugging traditional outdoor lights. The fact that they are solar powered means there are no more wires in my yard, creating a cleaner, safer outdoor environment. If you're thinking about transforming your outdoor area into a warm and bright haven, these solar lights are the way to go. You won't be disappointed!
The size and power are exactly what I need. The price was right, and shipping was free and fast. They look solid and are expected to last for many years. The time from ordering to arrival was incredibly fast, and the customer support is absolutely top notch. Buy with confidence.
Bought 6 of these and they look great. Have had no issues after 3 weeks. Great solar panel, good value for money, haven't had any issues, if we were to increase the wattage we would buy another panel from here.
This starter is a lifesaver! I can't believe how well it performs! Just last week, my car broke down in a grocery store parking lot and the battery surprisingly died when I needed it the most. It was nighttime and cold, so I was really anxious. Luckily, I purchased this car starter a couple weeks ago on the recommendation of a friend. First of all, the size of this starter is really convenient. I can easily fit it in my glove compartment and it hardly takes up any space. The design is also modern and looks really cool, and the included storage bag is awesome. It's even easier to use. I clipped the starter onto my dead battery and followed the steps in the instructions and the car started in a flash. The whole process took less than 3 minutes! I was really surprised at how efficient it was.I even used it to charge my laptop once, which was definitely a bonus! If you're considering buying a reliable car starter, look no further. This little device could be your savior when you need it most. I have no hesitation in recommending this product to all drivers - you won't regret it!
I am very happy with the car starter from werchtay. Not only does it help me start my car, it also charges my cell phone. The design is safe and easy to use, even for a novice electronics user like me. It also comes with its own LED light, which makes it especially convenient to use at night. I'm impressed with its versatility and durability. I recommend it to all my friends who need a reliable starter.
This is an extremely bright street light. Stylish and beautiful, it is equipped with 504 LEDs and lights up my entire backyard, giving a sense of security. Installation is very simple with three screws in the mounting bracket. The light assembly slides into the base. It is IP65 rated, which means it is waterproof, frostproof and heatproof. Well worth the money and I recommend it to anyone.
Our neighborhood recently installed these solar street lights and we feel much safer walking home at night. Not only are they energy efficient, but they are easy to install and don't require complicated wiring. So I bought a couple for my own home, one for the compound and one for near the utility room, and am very happy with the investment, and won't have to worry about electricity bills or use in the future!
I like it
Solarpanel 12V 50 100 120 130 150 170 200 Watt Solarmodul Mono Photovoltaik
The price was what earned the 4 star. I originally ordered a complete solar kit, but once order was placed I was informed you didn’t have any kits available, but I received a discount on 8 solar panels. One panel was broken on delivery and 2 others had slight damage. The broken panel was replaced at no cost. Overall I’m happy with the panels and the price that I paid for them, but I would have preferred the entire kits.
Installed on top of my RV. Works great!
Installed in 4s configuration facing 170 degrees sse and producing the rated watts at peak sun, sometimes even more that rated. These are high quality bifacial panels.
Unforeseen circumstances has delayed permanent installation, so except for testing the panels for shipping damage, this pair has not been used. The identical pair preceding were tested in a temporary array of 4 PV Panels connected to my Bluetti AC 300 Power Station. This array fed the Bluetti & converted to power my household appliances in a test period, where I got familiar with using PV Panel & Bluetti. This system, along with it's twin will eventually power our off grid residence. The delay lies with getting the property ready, My PV Panels are good to go.
Super gut
2500W/5000W Reiner Sinus Wechselrichter 12V auf 230V mit Fernbedienung
Fantastic product. Will likely buy more
Does this battery have a balancer? If so, is it passive or active?
12.8V 1280Wh/100Ah LiFePO4 Battery with BMS Protection - Limited $143!
Panels well packaged . The panels work great on my travel trailer. Output is better than I through this time of year Oct. Would by again!
replaced the nonworking hundred watt flexible panel on my camper
Arrived quickly and works well
Fast shipping and well packed and works great
Thank you for a quality product!
Charge controller instructions are not good and can't download app in English so can't connect with Bluetooth for charger or battery bms otherwise is working good as far as I can tell
It’s working as expected no problem
these panels when I tested were producing almost the same if i turned them around ,these are backup panels but they will definitely work for my needs
I have not got enough of Your Solar Panels to Commission this Charge Controller. I only have 2 100 Watt Panels due to Funds being a Disabled Marine Corps Veteran on a Low Fixed Income. I do have 2 - 12 Volt Batteries for a 24 Volt System and an Inverter already.
advertised capacity is false. I bought 2 x 300AH and they are fully discharged after using 225AH and 237AH. thought i was getting a great deal but got ripped off instead. seller refused to warranty them. if you buy this brand, you are taking a risk.
3840Wh (12.8V 300Ah) LiFePO4 Battery for Reliable Energy Storage
Working as advertised so far but am getting some buckling of panels “ill send pictures to CS” but the price is outstanding for buy 1 get 1 free sale and very very fast shipping and well packaged!
I already have a full solar system, but I added this as a flexible power source for my fence light and cameras. Now I don’t have to run extra wiring. Works well as a supplemental panel, especially since it’s waterproof and needs no maintenance.
This little kit packs a lot: monocrystalline panel, tilt stand, waterproof build, and even USB-C output? That's rare at this price. I tested it during a short boat trip and it held up well even with sea spray. Highly recommend for anyone looking for a lightweight solar option.
