Yes, the sunlight will increase your algae growth. However, you might be able to work around it if you have an excellent skimmer, and don't overfeed the tank. It will also depend on how much light the tank is getting from the windows, and how big a janitor crew you have. If you were going bigger, I'd say grab a few tangs and they'd help with the algae, but most tangs need more room than you're planning on having. A Scopas tang might do ok in a 75, but that's about the only one I can think off offhand that I'd put in a tank that small.
If you have a better spot for it, I'd seriously consider putting it there. It isn't that you can't manage it, but it's an extra hassle on top of all the other issues that come with building miniature oceans in the middle of the country.
Just my 2 cents - take it for what it's worth.
