thank you for your answer dan, seems like it wont be that expensive as i thought afterall, do i need a microinverter for every panel installed? how do you manage/know how much power are you generating? is there an app that links this info to your phone or something like that? im asking this because in the microinverter image i see like a wifi antenna, buying them at $92 seems pretty nice, sadly in mexico they are at $4500 pesos each one which is roughly $260 dollars lol
So with Micro Inverters, you have one on each panel. You then string the inverters together, up to 15 max, and then connect them to a 240V 20A breaker and you're done. These are grid tie inverters, so they won't even turn on until they see a solid 240V @ 60Hz coming from the grid. Also, when the grid goes down, they immediately shut down. This a mandatory safety feature so that linemen working on the lines won't get zapped from a gried tied system putting power out across a downed grid.
To monitor the production of the individual panels, you'll want this guy:
http://www.doubleradius.com/Manufacturers/sunMAX/Ubiquiti-sunMAX-Solar-Gateway.htmlIt snaps onto the side of the solar panel array and has an Ethernet port and can handle about 60 panels. It communicated with the micro inverters using low power Blutooth. That's what those antenna's you see are for. The Solar Gateway has a build in webserver that you can point a browser to and see solar production data for each panel, as well as the overall production from all panels in the array.
