Large Size Automatic Chicken Coop Door Solar - Powered Auto

The Verdict

If you’re tired of waking up at dawn to let the girls out — or worse, losing a bird to a predator because you forgot to shut the door — an automatic coop door is a genuine quality-of-life upgrade. The Large Size Automatic Chicken Coop Door Solar is one of the more popular options on Amazon right now, holding a 4.3-star average across 215 ratings. But popularity doesn’t equal perfection. Here’s what you need to know before handing over your money.

What’s actually in the box

The package includes the door unit itself, a separate solar panel with mounting bracket, the control box, and hardware. There’s no battery included — you’ll need to supply your own 12V rechargeable battery (typically a 7Ah or 9Ah sealed lead-acid will work). The door opening measures roughly 12 inches wide by 14 inches tall, which is genuinely large enough for heavy breeds. As shown in the product image, the panel mounts separately from the door, so placement flexibility is decent. The control box supports both a light sensor and programmable timer, giving you two ways to automate open/close cycles.

Real-world performance

The dual sensor system is the standout feature here. Set it to light-based operation, and it opens at dawn, closes at dusk — no programming needed. Or use the timer mode for fixed schedules. Owners report the light sensor is generally responsive, though overcast days can trigger earlier-than-expected closing. One reviewer noted, “It closed at 4pm on a stormy day and my hens were locked out in the rain. I switched to timer mode and haven’t had an issue since.”

Battery life is solid when the solar panel gets adequate sun. In cloudy climates, expect to manually recharge every 2-3 weeks. The motor itself is reasonably quiet and opens in about 10-15 seconds — fast enough to not spook birds waiting at the door.

What buyers consistently praise

Across the reviews, three themes dominate. First, installation is straightforward for anyone comfortable with a drill and screwdriver. Second, the large opening genuinely fits bigger birds — a common complaint with smaller automatic doors. Third, the solar panel eliminates the need for running power to a coop, which is a huge deal if your coop sits 100 feet from the house. As one five-star reviewer put it, “Set it up in an afternoon and haven’t touched it in three months. Worth every penny.”

Where it falls short

Honesty requires addressing the weak points. The housing is UV-stabilized plastic, and several reviewers report stripped screw holes during installation. It’s not a dealbreaker, but it tells you this isn’t a build-it-once-and-forget-it-forever product. The solar panel cable is short — about 6 feet — so coops in partial shade will need an extension. And quality control is inconsistent: a handful of buyers received units with slightly bent door tracks that required manual adjustment before smooth operation. If you’re not handy with pliers, that’s a frustrating start.

Who should buy this

This door suits backyard chicken keepers with 4-10 birds who want reliable automation without running electrical lines. It’s ideal for people whose coop is far from a power source, and for those with mixed flocks including larger breeds. Skip it if you have a tiny bantam flock (the door is overkill), if you live in extreme cold where batteries drain fast, or if you demand all-metal construction and perfect out-of-box fit.

Frequently asked questions

Does it work during winter? Yes, but battery performance drops in freezing temps. Insulated battery boxes help, and the solar panel still charges on sunny winter days. Expect more frequent manual charging in deep winter.

Can predators push it open? The motor holds the door firmly shut when closed. However, the plastic housing won’t stop a determined raccoon from prying at the edges — add a predator-proof latch for extra security.

How long does the battery last on solar alone? With 6+ hours of direct sun daily, most users report indefinite operation. In overcast conditions, expect 2-3 weeks between manual charges.

The Verdict

Buy it if you want dependable, solar-powered automation for a standard or large-breed flock and you’re comfortable with minor DIY adjustments. The dual sensor system, generous opening, and true solar operation make it a strong value at this price point.

Skip it if you demand metal construction, need a longer solar cable out of the box, or want zero tinkering — this door occasionally requires a little patience.

Rating: 4.2/5 — A genuinely useful product with a few quality-control warts. For most backyard keepers, the convenience outweighs the flaws.
