Methodology: How We Ranked the Best Solar Companies in Los Alamitos
EcoWatch's solar experts analyzed each solar company in Los Alamitos based on criteria such as its reputation in the industry, customer reviews, services, warranty coverage and financing. Using this solar methodology, we used the data we collected to rate and rank each company and narrow down our picks for the best solar companies in Los Alamitos
Below are some the criteria we examined specifically for California solar companies
- Brand reputation and certifications (20%): We take each company's Better Business Bureau (BBB) score into consideration, as well as how long the installer has been in business (at least 5 years is required, 10 preferred) and what type of solar certifications it holds.
- Customer reviews (20%): Trust is a top priority at EcoWatch, so we take customer experience under close consideration. We scour different review sites and customer testimonials when ranking our top solar companies, checking sites such as Trustpilot and Google Reviews. We also consider any potential complaints or lawsuits filed against these companies and award or remove points accordingly.
- Warranty (20%): A company earns a perfect score in this category if it offers 25-year warranties that cover performance, product and workmanship. The industry standard that we measure companies against is 25-year product and performance warranties, along with a 10-year workmanship warranty. We also look closely into the track record of the post-installation support each company provides in terms of honoring its contracts
- Solar services (10%): All of the companies we review install solar panels, but we award companies higher points if they offer additional services for customers, like battery installation, energy-efficiency audits, and EV chargers.
- Pricing and financing (10%): It's hard to get exact quotes for solar projects, but we use marketplace research to determine how each company prices its equipment and installation services. Additionally, companies that offer more help for panel financing — like in-house loans, leases, or PPAs — score higher than those that don't.
- Availability (10%): The bigger the service area, the higher the company will score.
- Transparency and accessibility (5%): Solar installers that offer free consultations and easy contact methods score higher in this category.
- Environmental, social and corporate governance factors (5%): A company earns a perfect score in this category if it offers public data disclosure, addresses end-of-life (EOL) products or processes, and demonstrates a commitment to uplifting the communities that it serves.
The Cost and Benefits of Solar in Los Alamitos
Solar panels are powered by a free energy source — the sun — but before you can take advantage of this you will first need to pay to install your panels. Some significant things that affect the cost and possible savings include:
- Whether or not your roof gets a lot of direct sunlight: This, plus your roof configuration, affects affect how much power your solar panels can generate.
- How much you spend on energy: The average family in Los Alamitos shells out around $750 a year on power alone, so you could gain that much in savings.
- Choice of solar panels: The type of solar panels you choose will affect your total cost. High-efficiency monocrystalline panels will cost more upfront but can also save you more money over the lifetime of your system. If space isn't a constraint for your project, you can go with a higher number of more affordable panels.
- Incentives: The federal solar investment tax credit currently lets you reduce your taxes by 30% of the project cost. Your state and even local utility companies may also have incentives and rebates that you can benefit from. Plus, you can save about $25,000 over 20 years on your utility bills, without incentives.
So is buying solar panels worth it? Whether you want to lower your electricity costs, carbon dioxide emissions or both, solar panels are a solid investment for many Los Alamitos homeowners.

A lot of people want to do what they can to help protect the environment, which for many is the main motivation to install a solar system. But you may be wondering — how much exactly can you help the environment by making the switch to solar? One thing that can dramatically affect your carbon footprint is how long your commute is and how much you drive in general. If you go solar and have an electric car, you can vastly decrease your carbon dioxide emissions by charging your car at home. After you go solar, your carbon emissions can be lowered by about 50 pounds a year. Since solar power is abundant and produces electricity without a carbon footprint, making the switch to solar power is one easy step you can take to help protect the environment.

What is the top solar company in Los Alamitos?

What are the pros and cons of solar power?
The main advantages of solar power are that it can lower or, in some cases, totally eradicate your electricity bills, improve the value of your home and cut back on your carbon footprint. The main disadvantages are that solar panels can be costly to install, you may not see as many savings if you don't use a lot of electricity and whether you can install solar panels depends on your roof configuration.
How long does it take to see a return on your investment after installing solar panels?
The average payback period for solar panel installation is about 7.3 years, but the exact period is influenced by the cost of electricity where you are, incentives and net metering programs.
How often do solar panels need to be replaced?
Even though the average lifespan of solar panels is 25 to 30 years, that doesn't mean they are completely unusable. What this means is the amount of energy they produce will have decreased by about 0.8% each year since installing them. You can choose to replace them after having them for that long or you can keep using them at a lower efficiency after that time.
