Also, I looked up my numbers from a project for a class last year which involved solar panels. We found that it cost somewhere in the neighborhood of $350-$400/m^2 per solar panel (lasts 25 years), so the solar panels themselves cost around $8750-$10000 at 5 m^2 per panel. Then they'd have to buy an inverter and do some wiring and stuff (the cost of this shouldn't be too high though). So I'm guessing that the turbines produces the bulk of the electricity because they invested a lot more money on it. That, or the people doing this are clinically dumb.
