Run your window AC with just 2 solar panels when sun shines. Easy DIY project you can do in one day. (www.youtube.com)

Obviously there's lots to improve here, but for plenty of people this is a great starting point.

Nope, you're right. AC uses a lot of power, and 1000W of solar panels would take up at least 5 m2. You would need around double that if you're gonna run solely on solar power, too, as well as a big ass battery bank.

The guy in the video is using a 5000 BTU unit to cool a small room, though, and manually switches to grid power during the night. Would definitely save money.

If I had a house with plenty of space, I would definitely make the investment.
