Economical 25W solar kit. Works good. This is actually an upgrade for a previous chicken coop door. (See picture) Provides 12 VDC for LEDs and timer circuit on the automatic door, also purchased on Amazon. I decided against purchasing the Amazon Seller’s upgraded battery charger/controller based on reviews. This unit provides a decent charging to my 12V 10Ah Lithium LiFePO4 battery with no issues (yet). As pictured, the charge controller is a 10A PWM, only has the most basic functionality. Indicators are all LED, but it is useful without detailed information. The battery LEDs are in 25% increments, my battery is 75% full in the picture (3 LEDs on) and charging. I needed the polarity reverser, that was included in the kit for the coop door to function. You can also manually reverse the wiring from the controller front. Solar panel output was 24V dc (under no load), which was great in Washington state weather. The kit was easy to install with basic electronic/solar knowledge and experience being helpful. I also installed two connectors (ordered separately) going in/out of the coop. I think it’s an excellent starter kit that makes daily life easier. If the charge controller fails, it should be upgraded based on your power/current needs. Example – 20A PWM with digital display for V/C(I)/P stats. Con: Manual and Amazon details do not match. The info on Amazon is more correct. 1) This is a 25 W monocrystalline not a polycrystalline panel – the manual is wrong. 2) Charge LiFePO4 batteries with Click 1 (my choice) or 3 when setting up the charge controller. Manual incorrectly says to use Click 2, which is for gel batteries. Hence, recommend to upgrade charge controller when given an opportunity. I still need to organize my cables.

Needed to power an irrigation pump for a greenhouse on the distant part of our farm. This panel and controller charge a deep-cycle sealed battery. Panel is solid and generates decent power even on a cloudy day. Charge controller has a handy USB output that can charge my phone while working on the greenery. If I build another of these – or automate the chickens place – this will be the unit I look for!

The packaging was subpar for one. It arrived in a single extra thin layer cardboard box around the panel itself. No foam spacers or bump protection whatsoever, just a thin plastic sheet. A bump or ding on the side is going to hit the panel directly.
Second, one photo is inside under a single “warm” color fluorescent light. It yields about 1.4v which maybe ok, that’s expected.
BUT outdoors in indirect sunlight it yields only ~1.56v. That is a bit strange. You would think even in indirect sunlight it would benefit from photons on the invisible spectrum over fluorescent lighting…but that does not appear to be the case.
I am going to try it on my vehicle anyways, and will update if it works. But it appears this panel is a low performer.

It hasn’t been up very long but was so easy to hook up. Plus I bought farmlite chicken coop about a year ago and has worked great , sent a txt to see about hooking up solar I had lost the wiring for hooking up solar and they sent me one free of charge, great company

Had a problem with the charge controller but the seller took care of it immediately, great customer service. The solar panel has a very good output and very close to rated output even where we live.

The solar panel and the charge controller itself work great. The wires are junk, wasting 10-20% of the total solar power and causing charging issues. The charge controller is not waterproof or even water resistant, and it takes patience to attach wires to the green connector. Otherwise, the charger works well. Rather than return it, I fixed these problems for about 15 dollars.
Actual specs:
I measured this unit putting 1.4 amps into my low car battery on a sunny day in December in Maine. That’s about 18 watts in the middle of winter, pretty good for a 20 watt panel. That was before I fixed the wiring.
The label on the back of the solar panel has slightly different specs than the Amazon title. It says 25 watts max power. See attached photo.
Charge controller:
The included charge controller works well. It’s an intelligent 3A PWM charger that automatically switches through 3 charging phases: bulk, absorption, float (trickle). It has an LED to indicate when it has solar power and what charging phase it’s in. It will prevent over discharging below 10.8 volts and over charging above 14.4 volts.
At one point I thought my charger was broken and started looking for a replacement. A decent PWM charger like this runs 15-20, so it’s a decent value. I later discovered the charger was fine, the problem was the cheap included wires (see below).
I was a little worried about the charger consuming battery power when there isn’t any sun. Cheaper chargers use a little battery power overnight and on very cloudy days while waiting for the sun to come back. I wanted to leave my system unattended for months during our short and cloudy winter days without discharging my battery, so I can’t tolerate much current drain when the sun is gone. Amazon didn’t list the current drain when I bought it. I measured the charger’s current drain with no sun at about 1mA. That seems pretty reasonable compared to 10-50mA with other chargers. The charger ships with a spec sheet, which lists the current drain as 1.5mA (see attached).
The spec sheet says the charger is made for Gel batteries. It seems to work fine on my SUV car battery though.
Cheap wires:
I measured my battery voltage while charging on a sunny day. 13-14 volts is normal, but I was only getting 12.4 volts. I thought the controller had gone bad so I tried another one. Same problem. I tried lots of things, went over all the connections many many times but nothing worked. It definitely had power coming from the solar panel, it just wasn’t getting to the battery. Over a few days I did notice the battery charge increasing very slowly, but the charger kept thinking the battery was fully charged too soon and kept turning off (trickle mode) too early. I finally had the idea to check the battery voltage at the other end of the battery wires (where they connect to the charger). The charger was putting out 13.6 volts at about 1.5 amps, but only 12.4 volts was getting to the battery. That’s 10% of the solar power being wasted by wire resistance! It was also enough to fool the charger into thinking the battery was charged and switching to a low power mode, which throws away even more of the generated power. It will still charge your battery eventually assuming you aren’t using the battery for something else, but it will be slow.
I replaced all the wire with normal 16 gauge wire, and it fixed everything. I measured 13.6 volts at the charger and 13.5 volts at the battery while charging at 1.5 amps. It charges much faster now, and I can use the battery to power other things. I attached a picture of the cheap wires they include and some normal 16AWG wires I replaced them with. On the outside it’s deceiving because the cheap wires look reasonably thick. But if you cut into it you’ll see the cheap wires are almost all rubber insulation and have very little actual metal inside.
The actual solar panel appears waterproof and has white silicone around the edges on the back. However the charger is definitely NOT waterproof. It came with clear silicone applied along the bottom of the green connector, but that’s pointless since the top and sides of the connector have bigger openings and were left unsealed. I needed the charger to work outside in the winter in rain, snow, ice, etc., so any water intrusion could easily freeze and damage things. You could always buy silicone and seal all the openings including the holes in the green connector where the wires attach, but then it will be a pain if you ever want to remove and reattach the wires later. I ended up opening the charger box and spraying conformal coat to waterproof all the electronics. Then I drilled a 1/8″ hole in the white box to allow any water that gets in to drain back out. Takes about 10 minutes. So far it’s holding up well to our Maine winter environment!
I didn’t see any of this information posted anywhere else, so hopefully some people will find this info helpful!

Works just like the ad said. I did also purchase 2 extension cables so that I could run the cables from the top of my carport where the solar panel is located, down to my farm tractor and lawn tractor.

I installed this on my backyard shed, which has no utility power, and use it to keep my mower battery charged. Works great and easy installation! Manual is included for setting up different battery types. The frame for the panel is a little flimsy, well see how it holds up to the Kansas winds.
