WindyNation 200 Watt (2pcs 100 Watt) Solar Panel Complete Off-Grid RV Boat Kit with LCD PWM Charge Controller + Solar Cable + Mounting Brackets

Although installed flat on the roof of our R Vision trailer, they put out a surprising amount of power. Up to almost 12 amps in fact. Here in the Pacific NW, (in eastern Washington) the sun is 67 degrees off the horizon in mid summer, so not even directly overhead. There's no point in angling the panels, there's no idea what direction we'll be facing when we find a camp site. I had a local HVAC place make the "leader" piece to keep 70 MPH wind from lifting up the panels while going down the freeway.I took a couple of stars off the easy to install rating because of the couplers they supply. One has TWO positives IN and ONE negative OUT. (and a vise-versa coupler) Probably great for hooking panels in series, but an annoyance when going parallel for 12 volts. I got in trouble in fact because I went end to end with the panels to minimize wiring slop, and they got crossed up. I had to splice the cables with marine (glue filled) heat shrink on one panel to add enough slack to redo the setup. I was NOT happy. That also means the "negative" marked coupler sends POSITIVE current to the trailer. That means double checking the panels to A) Be making voltage/power in sun, and B) the polarity to the controller is correct before connecting it.Other than that, it's not too hard to install the system. The refrigerator venting system generally runs top to bottom in an RV, so the cables went up into the screen at the top, then down into the trailer. I used loom all the way, so no chafing of cabling. From the controller, I ran cabling down to the power panel in the trailer. I did NOT run to the battery, and there's no real need in fact. I used a spare unused fuse slot in the panel for the solar feed. It works great, and looks like a factory installation.As you can see, I have a battery monitor. It's wireless and works great. The sending unit has a Hall Effect current donut the battery cable runs through, temp probe, voltage leads, etc. In my system, with the solar panels feeding the fuse panel rather than the battery makes for some readings you need to interpret. Since the power in/out is supplied from the same place as EVERYTHING in the RV, the current in/out of the battery itself can read ZERO amps. Only the SURPLUS of the solar panels goes into the battery if it's is NOT fully charged, and when the battery charge tops out, it no longer draws current and drops to 0.00 amps. You can be watching TV, have fans and lights running, and see ZERO current from the battery going either direction. That means the solar panels are supplying ALL needed power. Only when the sun goes down, will you see current coming FROM the battery. The battery cables are size 00 running 15 feet to the battery up front.So... you will see current coming FROM the battery at night, or low light dawn or dusk, (when things are on) and when the sun comes up, current will start going TO the battery. It can be as high as 11.5 amps from what I've seen, and if you start turning things on in the RV, that current will drop because some of that solar power is running items instead. That's what I mean by "surplus" current goes to the battery.For a solid month, I've let the panels do their job, (in the driveway) the converter breaker is OFF. When it's hot, a Fantastic ducted vent fan runs about 2.7 amps 24/7. By noon, the battery is fully charged, there's 0.00 current shown, and the fan is still running full tilt RPM. When camping, by early morning after my CPAP and bedside fan has been running all night, the volt meter by the bed will be around 12.2 volts, but when the sun comes up higher in late morning, the voltage will be 13.5 or more. The battery is a Crown 80AH. (Not enough room in the built-in battery box for a 100AH)I've waited a month to write this review.

At the time I ordered this kit, There was no ratings or comments. So I was cautious about ordering it. It was a great price. I calculated the cost to build my own set ording everything sepearte (including buying used panels from craigslist) This windy nation kit was the least hassle and the best cost.package arrived two days after I ordered it.All the parts were included and nothing damaged.It was simple to install on my truck camperThere was enough cable to run the panels from the roof to the the charge controller and enough left over to run cable from the charge controller to the batteries. Its a 40 ft long cable. so all you have to do is cut it to size. I cut mine in half to have one pos. and one neg. then i cut a bout 2 feet off of each to run from the controller to the batteries.Although the charge controller worked, I bought one that has a digital display on it (a "net meter 30amp" one that shows the percentage of battery you have left.)I love it. The standeard one my camper has only shows (low fair and good) now I see by percentage (example 78% or 91% and so on)Its November (low sun)and I installed the pannels "flat" on the roof and even with over cast, so they are currantly pulling about 50%. It still chages my 2-6v deep cycles nicely. I will add comments when the summer rolls around to see how much it producess thenI would buy from them again. Infact I am thinking of buying another kit from them to add to my camper.

The package arrived damaged and open on one side so I was concerned the small parts might be missing but everything was still in the box! Installation went without a hitch and the panels began charging my storage batteries immediately. Since I installed the Panels flat on the rooftop of my RV I was expecting somewhat less than peak performance, opting for safe, stabile and convenient mounting over orienting at a more optimum angle to the sun. My goal has been from the beginning to operate a dorm sized refrigerator as near to 24/7 as possible. I'm currently using two 1050 AH batteries as storage for overnight reserve. On bright rainy days the panels maintain my storage batteries at near full charge but at times on sunny days deliver more power than my batteries can store so I may have to add a third battery to have adequate storage capacity to tap the whole potential of the panels and run my refrigerator overnight. Since I expect to be off grid for several days at a time, I feel that this Windy Nation 200 watt Solar panel complete Off-grid Kit is exceeding my expectations. I intend to give it a complete shake down in about a month to see if 24/7 stand alone power is realistic.

This dolor panel kit was received in good condition. The install was easy and product works as described.I wish they would have stated the connectors needed to be installed onto the wires, also you get 40 ft of wire so actual run from controller to the solar panels is 20 ft. Also without adding washers to the mounting bolts they could pull through the holes in the frame.

This was my first time installing a solar system. I installed this system in a hi-lo camper and found this to be very easy to install. I did run short of wire but no big deal. The instructions were easy to follow. The system is working like I hoped it would to keep my two Optima yellow top batteries charged. In my opinion this system is worth the money.

Works like a champ. I've been using this for 1 year now. My batteries haven't even been low once the whole entire time.Easy enough to install but for a better install I'd get some dicor tape and put it down on every spot you are going to drill through the roof for the brackets though. This will help the roof material from lifting/getting an air bubble, once the drill bit peirces the roof membrane. Oh and order some extra solar wire if you are even close to being short. You'd hate to have to stall your install waiting for some solar wire to arrive because that stuff is kind of hard to find.
