Methodology: How We Ranked the Best Solar Companies in Oceanside
EcoWatch's solar experts analyzed each solar company in Oceanside 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 Oceanside
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 Oceanside
When picking a solar company, most homeowners or business owners worry about the costs above all.The cost of solar and the savings it generates vary depending on a few important factors such as:
- Average daily sunlight: Since Oceanside gets lots of sunlight, your solar panel system will most likely be able to generate enough energy to power your whole home, which affects how much your solar panels can save you on your electricity bills.
- Incentives: Something that can make your solar project cost less 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 a decent amount of money on your power bills, which can give you an average of $30,000 of savings over 20 years.
- Choice of solar panels: The type of solar panels you buy will affect your total cost. High-efficiency monocrystalline panels are more expensive upfront but can also lead to more savings over the lifetime of your system. If you don’t need to maximize efficiency, you can opt for a higher number of more affordable panels.
- Your home's power bills: Due to high monthly electric bills in Oceanside, you could save about $1,700 a year with solar.
So is installing solar panels worth it? Whether you’d like to lower your electric bills, carbon dioxide emissions or both, solar panels are a solid investment for many Oceanside homeowners.

Environmental Impact of Switching to Solar in Oceanside
One of the most compelling reasons to embrace solar power is to minimize your reliance on traditional energy sources like burning fossil fuels, which are hazardous for the environment.But how much can switching to solar actually affect the environment? The average person has a substantial carbon footprint. Between their car, which is responsible for over 10,000 pounds of carbon dioxide emissions every year, and energy for their home, it can be overwhelming to think about what to do. Switching to solar is a simple thing you can do to help.Since solar panels don’t release CO2 emissions into the atmosphere when creating electricity, they’re a good substitute for nonrenewable energy sources. In fact, you could expect to reduce your carbon dioxide emissions by about 50 pounds each year. The great things about solar power are plentiful — just like solar power is! That's why so many Oceanside residents have been happy with using solar energy.

EcoWatch's Oceanside, CA Solar Company Rankings FAQs
What is the top solar panel installer in Oceanside?
The highest-rated local solar company in Oceanside is Green Earth Electric, with a rating of 5.00 stars.
What are the biggest advantages and disadvantages of going solar?
A few of the biggest pros are that it reduces your power bills, it’s environmentally friendly, and it provides a significant return on your investment (ROI). The most notable cons are that solar panels don’t produce electricity at night, they cost a lot upfront and solar panels can be an eyesore.
Are solar panels worth it?
Solar panels call for a large upfront investment that usually costs at least ten thousand dollars, but whether or not solar panels are worth it depends on a collection of factors like how much you pay for electricity and the amount of direct sunlight your roof gets.
What is the best type 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 how much energy generation you want.
