How We Determine Our Rankings

There are a number of factors to consider as you search for the best solar installers in California.

Some of the specific factors we used for our rankings include:

Services Offered

For one, it's important to note that different solar companies may offer slightly different services. Most CA homeowners will want a company that provides a wide-range of services, assisting with everything from an initial consultation on their solar system to panel installation.

Installation Process

Also consider the specific steps in the panel installation process. How long will it take to have your solar panels placed? Is the solar provider insured? Will the panels be installed by a trained member of the company, or will it be a third-party contractor?

Coverage Areas

Some renewable energy companies in California have a wider field of service than others. It doesn't do you much good to hire a solar company that's only active in Sacramento if you live closer to Los Angeles in southern California.

Pricing and Financing

You'll want to consider your budget, which can be a determinative factor. Keep in mind that most solar companies are going to have fairly steep upfront costs, but you'll ultimately save a lot of money in the long run, thanks to the reduced electric bills. In addition, California offers state tax credits and incentives that can help you reduce these upfront costs. In our rankings, we have tried to celebrate companies that offer flexible financing options.

Professional Memberships

We generally recommend working with a company that maintains membership in the Solar Energy Industries Association (SEIA) or other professional association. Membership in these groups is a great indicator of the company's professionalism, workmanship, reputation, and reliability.

Types of Panels

Pay attention to the specific type of solar technology that is offered. Is the company certified to install leading brands like Tesla Powerwall, Panasonic, and LG? It never hurts to take a closer look into the company's tech portfolio.

Rebates

You can likely find solar rebates or federal tax credits by making the switch to solar energy. Will your solar energy provider help you make the necessary arrangements? It is often wise to inquire about these incentives on the front-end.

Warranty

Finally, we would recommend seeking an installer that can offer a good warranty. Panels can last 25+ years, and you will want to ensure your investment is protected for as long as possible.

How Does Solar Panel Installation Work?

As you compare solar companies, you may have some questions about the installation process. What exactly is involved in having your home enhanced with solar paneling?

The process should always begin with a consultation. A solar expert will evaluate how much energy you need, based on factors such as your home's square footage, appliances, and the number of people in your home. Additionally, the consultant will help you determine the best places on your roof to place solar panels so that they maximize solar energy absorption.

The company will then install the panels onto your roof and make sure that they are connected to your home and operating properly. Once installed, these panels will capture the sun's energy and store it in a battery. A component known as an inverter will then take this energy and turn it into an AC electrical current, which is the kind of energy you'll need to power your appliances and home electronics.

The goal is that the renewable energy you get from the sun will be sufficient for you to stop using electrical power from a utility company. What's more, making the jump to solar can help you reduce your environmental footprint. For those seeking clean and (in the long run) cost-effective home energy, investing in solar can be tremendously advantageous.

Is Solar Worth it?

Are you a good candidate for switching to solar? First and foremost, you'll need to take a look at your utility bill. Cost is one of the most important factors when considering if going solar is right for you.

One important note is that in CA, depending on the city where you live, you may actually work with the local utility company, like PG&E, for a power purchase agreement (PPA) or net metering service. The utility will still be connected to your home, but you will receive credits on your bill for the extra energy generated by your home's solar system.

This can be a little bit cumbersome, and you'll probably want to work with a solar provider that can help you coordinate with your local utility provider as well as help you get the permits and approvals you need. For CA residents, this is important to ask about as you seek out an installer.

Takeaway

If you're interested in going solar in California, the first thing you'll want to do is research different companies so that you can find the one that best fits your budget and your needs.

Solar energy can make a world of difference for you and your family. We hope this guide will be useful to you in evaluating some of California's top solar providers.
