There’s never been a better time to switch to solar in Los Angeles. With rising electricity costs across the country, Golden State residents can benefit from up to 90% utility bill savings. But who should you go with for your solar project? 

When deciding to add solar to your home, it's always a good idea to know which solar companies in Los Angeles are the best to work with for your specific needs. Solar panels are not all the same, nor are all of the solar companies available today. It is a good idea to compare several companies to determine which one is best suited for your needs.

How to Choose the Best Solar Companies

A number of factors go into choosing which solar panel company or solar installer is the best. Learn how to find the best Los Angeles County area.

Does the company educate you?

When choosing a solar company, you want to be sure you learn everything you can about solar power and how it works. It is critical to understand how a solar panel system may work, how much power it can provide for your home, and what the solar installer expects to do to meet your needs. You should understand how every component works, including energy production, solar battery function, inverters, and energy storage devices. Also, the solar company should tell you about available incentives and rebates and help you get them. 

What services do they offer?

Solar installers should help you with the entire process. This includes determining what home solar system is best suited for you and creating a custom solar system that works to meet your individual needs. Find out what solar services they offer, such as if they just handle the solar installation or if they will help with maintenance over time.

Is the solar panel pricing transparent and easy to understand?

Solar customers should understand how much it will cost them to install solar panels as a priority. That is, if you do not understand the solar lease, the power purchase agreement, or the solar panel contracts you’re signing, it is critical to look for a new provider. You want to be sure you have a full understanding of the cost of a new home solar system and what goes into the solar project. This should include any government incentives and net metering programs available to you and how they could save you money.

Does the company have a good reputation in your area?

Get to know the solar company well. You want to be sure the solar group has a solid level of experience meeting the needs of residents in your area. Do they have a good history of providing reliable products, and are their solar panels worth the investment? Or, do people complain about a lack of backup power or perhaps even that their electricity bill isn’t what the solar installers promised? Make sure that everyone in your area has a good experience with the whole process, from figuring out what you need to installing the panels.

What is the warranty coverage on the solar panel system?

Get to know the solar companies in your area, including the type of solar panel system they plan to install. You want to be sure that the solar panel installation company provides a long-term warranty on your system. In Los Angeles, CA, that should be around 25 years. Also look for performance ratings, workmanship guarantees, and maintenance options. In any case, the warranty should match the production output rating for the solar panel’s lifecycle. 

Are you buying or leasing them?

If you hope to take advantage of solar incentives for residential solar, you will need to purchase solar panels. However, some people may not want that large upfront payment. They may benefit, then, from the solar lease, where you will pay just for the solar energy produced by the panels but not own the panels outright. Solar panels that are leased may cost less up front, but homeowners who choose to lease may not be able to get tax credits from the government.
