Cold Sun is a solar-powered ventilation kit that cools your dog's house automatically. No outlets, no batteries, no wiring. Takes about 10 minutes to set up and runs itself from there.
On a 90°F day, the inside of a dog house can hit 120°F. That's not shelter — that's a health risk.
Wood and plastic insulate heat in. Without airflow, interior temps spike 20–30°F above ambient on sunny days.
Dogs can't sweat. They rely on panting and external airflow to regulate body temperature. A hot, still enclosure is dangerous.
Outdoor outlets are rare. Extension cords are a chew hazard (ask any dog owner). Battery fans die in a few hours. There hasn't been a good option — until now.
No electrician. No tools. Seriously, the whole thing takes about 10 minutes.
Peel-and-stick or use the included screws. Works on flat or angled roofs — doesn't matter.
Clip or screw the two weatherproof fans to any wall. Built-in grills protect curious noses and paws.
Fans spin automatically when sunlight hits the panel — the hottest part of the day gets the most airflow.
High-efficiency cells that still pull power on partly cloudy days. UV-stable housing rated for 10+ years outdoors.
100 CFM of combined airflow at under 25dB. For reference, that's quieter than a conversation across the room. Your dog won't care they're there.
16 feet of weather-sealed cable so you can route it however you need. No adapters, no splicing — it just plugs together.
Stainless steel grills over every fan. Keeps paws, noses, and tails safe. Won't rust, won't break if your dog bumps into them.
Measured in a standard wooden dog house on a 92°F day in direct sunlight.
*Results measured during independent testing. Actual reduction varies by dog house size, orientation, and weather conditions.
"Ok so my lab Cooper would literally refuse to go in his house from like May through September. Put this on last month and now he sleeps in there midday?? I stuck a thermometer in there out of curiosity and it was 17 degrees cooler. Actually shocked."
"Took maybe 8 minutes to put on? I didn't even need a drill for my house. The fans are weirdly quiet, like I literally had to hold my hand up to check they were on. My vet noticed it when she came for a home visit and asked me to send her the link lol"
"I foster dogs so I have 3 houses in my yard. Got the 2-pack first, liked it, came back for another single. No batteries to swap, no extension cord running across the yard. Probably my best purchase this year tbh"
An electrician visit runs $200+. Portable fans need outlets and die in a year. This is $59 and costs nothing to run. Ever.
1 panel + 2 fans + cables
2 panels + 4 fans + cables
Yep. They'll spin a bit slower, but it still works. And honestly, if it's cloudy out, it's already cooler — so you need less airflow anyway.
Nope. They're quieter than your fridge. Most dogs don't even notice them — they just enjoy the breeze.
The panel is IP65 rated, so rain is no problem. The fans are weather-resistant too. We'd suggest mounting them under an overhang if you can, but they hold up fine either way.
The single kit handles most dog houses up to about 24 sq ft. If yours is extra large or a kennel-style setup, grab the double kit.
It runs on sunlight, so it's active during the day — which is exactly when your dog's house gets hot. At night temps drop naturally, so it's not really needed.
For sure. People use them on chicken coops, rabbit hutches, sheds, greenhouses — basically anything that gets hot and stuffy.
