Methodology: How We Ranked the Best Solar Companies in Aliso Viejo
EcoWatch's solar experts analyzed each solar company in Aliso Viejo 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 Aliso Viejo
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 Aliso Viejo
When deciding on a solar company, most homeowners or business owners wonder about the costs the most.Some important things that affect how much it will cost and how much you could save include:
- System size and type: Some models are more expensive than others, so the one you decide on can raise or lower your initial investment. Plus, the more solar panels you need to buy, the more it'll cost.
- Your home's power bills: Because of high monthly electricity bills in Aliso Viejo, you could save about $1,700 a year with solar.
- Incentives: Something that can save you money on your solar project is the solar investment tax credit (ITC), which is a tax credit that lets you deduct from your taxes a percentage of the project cost. You can also save money on your energy bills, which can lead to an average of $28,000 of savings over 20 years.
- How much sunlight your roof gets: If your rooftop doesn’t get a lot of direct sunlight, your solar panel system won’t be able to produce as much energy, which will leave you with lower savings on power bills than a roof that gets plenty of sunlight.
Though a solar panel system costs a sizable chunk of money upfront, it can save you a considerable amount over the lifespan of your panels. The question of how much, though, depends on several factors, like the size of your solar panel system and incentives.

EcoWatch's Aliso Viejo, CA Solar Company Rankings FAQs
Which solar installation company is the best near me?
The best local solar company in Aliso Viejo is SunPower by Sea Bright Solar, with a rating of 4.40 stars.
Are solar panels really environmentally friendly?
Producing solar panels uses chemicals and produces toxic waste that can be harmful for the environment, which is the main negative thing about solar panels.
How long does it take to see a return on your investment after installing solar panels?
Solar panels usually pay for themselves in about 8.4 years, but your solar payback period will vary based on your utility costs. The higher your typical electricity bill, the quicker your solar panel system will recoup your installation costs.
What is the best kind of solar panel?
The different types of solar panels are monocrystalline, polycrystalline and thin-film. Monocrystalline panels are more efficient but also more expensive. Polycrystalline panels cost less but also less efficient than monocrystalline. Thin-film solar panels are flexible, so they can be used where the other kinds can’t, such as on curved surfaces or cars, but they are also less efficient. The best one for you depends on your budget, the layout of your roof and desired energy output.
