It's undeniable that California is the nation's largest solar market. It's the nation's most populous state and it's been one of the most proactive states in the US in terms of pushing for more solar power on homes, businesses and on the larger electric grid. In fact, according to California Distributed Generation Statistics, a state-run site, it has 703,133 distributed solar projects (like a rooftop solar installation), generating 5,637 megawatts (MW) of power for homes and businesses.
With all that solar power installed on homes and buildings it's no surprise that there are hundreds if not thousands of solar installers in the state. With so many it's hard to choose which solar installers are the best and which you should work with to install a quality, long-lasting solar system on your home.

Whichever California solar installers you talk to, here are some things you should be prepared to ask them and learn about their services: What licenses and certifications should California solar companies have?
A solar installer operating in California should have at least a C-46 Solar Contractors License. It requires that they've operated for at least four years and have passed state-mandated tests. Good solar providers should also have NABCEP (North American Board of Certified Energy Providers) certification. They also should hold a C-10 electrical license for installing photovoltaics.
If you're interested in solar hot water or solar thermal heating, look for a contractor with a C-4 license for boilers, hot water heating and steam fitting, C-36 license for plumbing, C-53 swimming pool for solar pool heating and for an HVAC system that uses solar, a C-20 warm-air, HVAC license.
What financing options do they offer?
There are now a plethora of solar financing options. Many offer zero-down financing but that's through a power-purchase agreement (PPA) or a lease. You can also qualify for many solar loans or purchase a solar system outright. There are a lot of differences though. Under solar PPAs and some leasing arrangements the panels are owned by the company--at least at first. Under loans and outright purchases you own the solar system.
What is their warranty?
Different parts of a solar system carry different warranties. So it's important to know whether your solar panels have a 25-year warranty or more and what that covers. Likewise the inverter, which converts the DC power produced by your solar panels to the AC power used in your home, may carry a 10-year warranty. But the contractor may also offer a workmanship warranty, guaranteeing the quality of work for a period of time.
Do they include or offer a maintenance and monitoring package?
Some installers offer long-term maintenance packages as part of the installation. They'll monitor your system and inform you if it's not performing to expectations. If need be, they'll replace any broken parts. With PPAs and solar leases this is pretty much standard since they own the system and with a PPA they make more money when everything is working properly.
