Correct Answer
About a million

And here's something for you to take back

The world's largest solar farm is currently (Oct 2022) in Bhadla in the state of Rajasthan, India.

It\s capacity is about 2.7 GW, 2700 MW.

The park thus has over 5,000,000 solar panels.

Just for fun, here's a thought: If a person were to try to clean each solar panel manually, working eight hours a day and taking about 5 minsutes to clean each panel, he will be doing it for about 50,000 days - 140 years - to finish just one round of cleaning.
