Solar Company Ranking Methodology
Click here to see a more detailed overview of our solar company ranking methodology.
The Cost and Benefits of Solar in National City
When picking a solar company, most homeowners or business owners wonder about the costs the most. The overall price and potential savings vary depending on a few important factors such as:
- How much sunlight your roof gets: If your roof doesn't see much direct sunlight, your solar panel system won't be able to produce as much energy, which will leave you with lower savings on electric bills than a house with a roof that gets plenty of sunlight.
- Your income and budget: This affects what model of solar panels you can afford.
- Incentives: The federal solar investment tax credit currently allows you to decrease your taxes by 30% of the project cost. Your state and city may also have various incentives that you can benefit from. Additionally, you can save about $31,000 over 20 years on your utility bills, without incentives.
- average energy usage: The more electricity your household uses on average and the larger your current electricity bills are, the more likely you'll benefit from switching to solar.
As a result of solar panels now being cheaper than ever as well as several solar incentives, they are a sound investment for many homeowners.

Our article on solar incentives has more information on the incentives you can benefit from in National City.
Environmental Impact of Switching to Solar in National City
One reason so many are thinking of installing solar panels is to help lower their environmental impact. Something many might be asking themselves is how much can they really help preserve the environment by switching to solar power anyway? In a city like National City where commute times can be pretty long, using solar power can help offset some of your carbon dioxide emissions from being on the road a lot. When you go solar, your carbon dioxide emissions can be lowered by about 50 pounds each year. Since solar energy is renewable and makes electricity without CO2 emissions, adding solar panels to your home is one easy step you can take to help the environment.

EcoWatch's National City, CA Solar Company Rankings FAQs
Which solar company is the best in National City?
In National City, Renewable USA is the most reputable local solar company. Our team of experts rates it 5.00 stars, so it's a solid choice if you're looking to install solar panels on your roof.
Are solar panels actually bad for the environment?
Producing solar panels uses chemicals and produces toxic waste that can be dangerous for the environment, which is the main downside of solar panels.
How long does it take for solar to pay for itself?
Solar panels generally pay for themselves in about 5.8 years, but your solar payback period will depend on your utility costs. The more your typical energy bill, the quicker your solar panel system will pay for itself.
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 costly. Polycrystalline panels are cheaper but also less efficient than monocrystalline. Thin-film solar panels are flexible, so they can be used where the other kinds can't, like on curved surfaces or cars, but they are also less efficient. The best one for you depends on your budget, roof layout and how much energy generation you want.
