Methodology: How We Ranked the Best Solar Companies in Signal Hill
EcoWatch's solar experts analyzed each solar company in Signal Hill 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 Signal Hill
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 Signal Hill
We understand that for lots of homeowners, the choice to invest in solar comes down to installation costs.The installation cost is just one important factor you should consider when looking into installing solar panels. How much it'll cost and how much you can save depend on things such as:
- System size and type: Some models are more expensive than others, so the one you want can raise or lower your initial investment. Plus, the more solar panels you need to buy, the more it'll cost.
- Average daily sunlight: Since Signal Hill gets lots of sunlight, your solar panel system will most likely be able to produce enough energy to power your whole home, which influences how much you can save on your energy bills.
- Incentives: Something that can reduce the cost of 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 power bills, which can result in an average of $25,000 of savings over 20 years.
- Electricity consumption: The average household in Signal Hill doesn’t use much energy, and consequently may not see as many savings on their power bills.
There are many great benefits of solar even with the initial cost of installation. It can help the planet and your bank account. In addition, it can boost the value of your home, leading to even more benefits if you want to sell your home later.

EcoWatch's Signal Hill, CA Solar Company Rankings FAQs
Which solar installation company is the best near me?
The best local solar company in Signal Hill is Solar Source, with a rating of 5.00 stars.
What are some of the biggest advantages and disadvantages of switching to solar?
A few of the biggest pros are that it reduces your power bills, it’s good for the environment, and it gives you a good return on your investment (ROI). The most notable cons are that solar panels don’t work as well when there’s limited direct sunlight, there is a high upfront cost and solar panels aren’t always aesthetically pleasing.
Are solar panels worth it?
Solar panels call for a considerable upfront investment that costs over ten thousand dollars, but whether or not solar panels are worth it depends on a collection of factors like the cost of electricity near you and the amount of direct sunlight your roof gets.
How long do solar panels last?
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 their energy production 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 continue to use them at a lower efficiency after that time.
