Not yet, but I'm right behind you. I have contracted with Petersen Dean, a local roofing company, that does solar installations as well. All permits and PG&E work will be included in the P&D purchase, and I also get the 30% federal tax credit. The total cost BEFORE tax credit will be $10.5k, or $3.65/watt for a 3.0kW system consisting of 12, 250W PV panels made by Canadian Solar, and an equal number of Enphase Energy M215 microintverters. Peak AC production should be ~2.6kW. To monitor this system, I also bought an Envoy Gateway based on PLC. This is used with a free lifetime subscription to the Enphase Enlighten web based monitoring system.

The plan is to do the roof install in two co-planar groups of 6 panels each on my two story residence with a Southwestern facing roof, totally unobstructed, with a 18 degree pitch. Should be great for Summertime production. I look forward to having this system installed in another couple of weeks, hopefully when the weather is trending toward clear, sunny days as Spring approaches.
With PG&E's Net Energy Metering (NEM) for PV residential customers, together with my current E-9A special EV rate plan, I should be close to a net zero electricity consumption annually even with two EVs to keep charged in the household.
Btw, here's one of the better website based solar calculators for helping to figure out all the financial aspects of a PV solar roof installation.

Good luck with your PV install and CONGRATS!!! :mrgreen:
