An interesting DIY solar power project at Kickstarter

2. I have been re-reading through this

And they seem to be feeding power via microinverters back into the home system using main current to sync up. So, you would need to be careful to size your system so that your daytime draw will not be less than you are pulling in from the panels.

They do talk about different breaker ratings depending on how big your system is and being able to be connected to 220v circuits.

They claim their mounting brackets are rated to 70 mph, whereas my roof mounts are rated to 120 mph. I would probably ground mount this type of system.

I would definitely want an electrician to look over this.
