Hello Jennifer
My personal experience is that you're going to have to pay for it, if not the panels themselves, then something else. Those panels may be only 50 cents a watt, but are they only that price when the installer mounts them? So, how much will you have to pay for installation? Then there's wiring, the grid tie, inspections, ect. What you need to look at is the TOTAL cost, not the cost of just the panels.
In my own personal experience buying panels I recently came across this deal on Amazon.

I thought wow, only 85 cents per watt. Once it was time to take out the credit card, I noticed the 120$ fee for shipping. That automatically raises the price 50%. Still, panels for 1.23$ per watt aren't a bad deal; bought them and have them up on the roof right now making power. They are good quality, and I am happy with them. BUT, that's not the price I thought they'd be.
Remember, when something sounds too good to be true, it probably isn't.
