Our solar panel performance.

Post has attachment
Still waiting on Ameren to give us our new meter, but in the meantime, I got permission to run a full day test of our solar system today. Here's the live chart: http://pvoutput.org/intraday.jsp?id=25429&sid=23193

The solar system is now wired into our home wiring. Now we just need a new bi-directional meter, inspection, and the monitoring device needs to be plugged in.

The monitoring device is cool from a techie perspective. The microinverters send data encoded on the power line about their production and the monitor (about the size of programmable thermostat) plugs into an outlet and decodes that data. It also plugs into our home network and sends the data off to a central repository so that we can view reports from the web and they'll get alerted if something malfunctions. They can also push firmware upgrades over our home wiring to each microinverter. How's that for cool?

This is what 5.2 kW of solar panels looks like. :-)

Yesterday they got all of the racking and microinverters installed. They started on the panels a little after 9 this morning and around have around 1/2 of them installed on their racks and plugged into their microinverters.

After that's done, they'll just need to run the cabling to the basement and call the electrician to do their part. Then we have to wait for the inspection and a new two-way meter from Ameren to start producing power.

See the little box hanging from the rack? That's a microinverter. Each panel gets its own. It's job is to convert DC to AC and also provide peer panel monitoring and statistics.
