We added a system to our home last year and here are some thoughts (not necessarily related to Ellwood):
First - For any questions on solar in general, you'll get better answers from existing owners and
SolarPanelTalk as opposed to the vendors. You'll want to evaluate the vendors based on their installs, etc.. But don't rely on them for advice on equipment choices (panels, inverters) or rebate information. It's like dealing with a salesman at a car dealership.
Second - Make sure your roof doesn't need repairs any time soon. You probably had this inspected when you bought the place.
Third - Don't lease.
Fourth - All the vendors are going to ask you for copies of your electricity bills (so they can scope out a system of the correct size).
Fifth - When you call, you want to avoid a salesperson and speak to the president or whatever. If you get a salesperson, the price you get quoted will be higher. INSIST on getting a quote over the phone. Don't let them come to your house to meet you - it will be a waste of time.
Sixth - There are several companies in SoCal that do a lot of business:
Solar Optimum,
LA Solar,
Sunline Energy, and
Infinity Solar. They have good reviews on Yelp and they are able to discount the prices big time.
When comparing prices, stick to the pre-tax credit, pre-rebate price so that things are consistent. This is the price you want to negotiate with the vendor. Under $3/watt is definitely doable. We ended up with SolarWorld 285 panels and SolarEdge optimizers.
