The Cost and Benefits of Solar in San Marcos
For most homeowners, whether or not you should invest in solar panels depends the most on the cost. Some important things that impact the upfront cost and potential savings over time include:
- The amount of sunlight your area gets: Due to San Marcos' very high amount of average daily sunlight, you should be able to save a lot on your power bills.
- How much energy your home consumes: Households that need plenty of energy each month may need more solar panels and, therefore, be more expensive, but will also enjoy more savings over time.
- The kind of solar panel system you have the money for: This hinges on how much you're willing to spend upfront.
- Incentives: The federal solar investment tax credit, which everyone qualifies for, lets you deduct 30% of the cost of your solar system installation from your taxes. Additionally, not including incentives, you can save about $31,000 over 20 years on your energy bills.
Thanks to solar panels now being cheaper than ever as well as various solar incentives, they are a sound investment for the majority of homeowners.

There are quite a few federal, state and local rebates and tax credits that earn anywhere from 30% to 50% of your money back after installing solar panels. For detailed information about local incentives, visit our our article on solar incentives.
Environmental Impact of Switching to Solar in San Marcos
One of the reasons so many people are considering adopting solar energy is to help bring down their environmental impact. You may be asking yourself — how much does making the switch help the environment anyway? An important thing to consider is your overall carbon footprint. For example, if you have a long commute, your footprint may be larger, so adopting solar energy for your house can help offset that. In San Marcos, the average person can lower their carbon footprint by 50 pounds a year once they go solar. If you want to do what you can for the environment, you'll likely recognize that there are many benefits of adopting solar energy other than just saving money on electricity. You can also help preserve the environment, which some would argue is more valuable.

EcoWatch's San Marcos, CA Solar Company Rankings FAQs
Which solar panel installer is the best in San Marcos?
In San Marcos, Renewable USA is the top local solar company. Our team of experts rates it 5.00 stars, so it's a good choice if you're planning on installing solar panels on your roof.
What is the negative environmental impact of solar panel manufacturing?
Solar panels can be detrimental for the environment when manufacturers use toxic chemicals in the manufacturing process. Chemicals can make solar panels difficult to recycle safely once they've reached the end of their lifespan. Solar panel manufacturing uses a lot of energy as well. The energy payback period is about 1 to 4 years.
How long does it take to see a return on your investment after buying solar panels?
Solar panels usually pay for themselves in about 5.8 years, but your solar payback period will vary based on your utility costs. The higher your typical electricity bill, the faster your solar panel system will pay for itself.
What are the different types of solar panels?
The different types of solar panels are monocrystalline, polycrystalline and thin-film. Monocrystalline panels are more efficient but also more expensive. Polycrystalline panels are less expensive but also less efficient than monocrystalline. Thin-film solar panels are flexible, so they can be used where the other types 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 efficiency you're looking for.
