I really like the eGauge (http://www.egauge.net/index.php), and have one on my house : http://egauge68.d.egauge.net/. It's a small operation out of Boulder.
The device uses CTs and voltage taps, so you can measure just about anything, like any specific sub-circuits or loads in addition to the main house and PV inverter output circuits. It has a built-in internal Homeplug adapter, so the customer just needs to put a small wall adapter at their router to post their data to the website. I've never worked with wind systems but as long as there is an AC circuit to monitor, you can put CTs on it. The downside is that you don't get an automated alarm if the inverter goes down, which you can get from Fat Spaniel, Energy Recommerce (now Solar Magic), etc. But the eGauge system is simple and pretty cheap, and you also don't pay any monthly fees like you have to with the others. My favorite thing about it is the interface; the graph makes so much sense and is nearly live. We've installed 8 of these over the last couple years, and the customers love them, because it makes their energy use patterns so clear.
