It can withstand wind pressure up to 2400 Pa and snow load up to 5400 Pa. The panel is waterproof, making it ideal for outdoor or winter use. Consists of monocrystalline cells for high conversion efficiency.
  • 🔋【Protect the Battery】The 10A PWM charge controller in this kit allows the expansion by wiring more 12V 25W panels in parallel. It also can prevent the battery from overcharging, over-discharging, over-voltage, short circuit, and reverse current issues. 2 indicators for easy observation of charging and discharging status. With USB 5V/2A output port.
  • ⛵【360°Adjustable Mount】Equipped with solar mounting brackets, the mounting angle can be adjusted for better sunlight reception. Pre-drilled holes on the back of the panel facilitate quick installation and securing. The connection cable is SAE connector, easy to connect and install.

Great solar kit, but cheap wires. NOT waterproof
4 Stars
Great solar kit, but cheap wires. NOT waterproof
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.Replacement wire: https://www.amazon.com/dp/B00NSGCVWI/ref=cm_sw_r_cp_awdb_feSyyb487STEMWaterproofing: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!Conformal coat: https://www.amazon.com/dp/B00BXSMNWG/ref=cm_sw_r_cp_awdb_AbSyybQ2NH5G4I didn't see any of this information posted anywhere else, so hopefully some people will find this info helpful!

Reviewed in the United States on December 26, 2023
This is a very good door. I first had it hooked to the grid and was working as advertised but if elect was off for any length of time the clock would be way off. So I ordered the 25 watt solar panel and battery that was recommended and installed it. It is working great. My panel is blocked by trees some what but is still charging very well. Only concern will be in the summer and the trees fill out. But that is not the systems fault. But as sensitive as system appears to be I think I will be ok. All being said if looking for an auto door this is a very good choice !

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!
