The Cost and Benefits of Solar in Fairfield
For many homeowners, whether or not to invest in a solar energy system comes down to the cost. There are a few factors you should consider when trying to figure out costs and your potential savings, including:
- The amount of sunlight your roof gets: If your roof gets limited direct sunlight, your solar panels won't be able to generate as much energy, which will leave you with lower savings on power bills than someone with a roof that gets plenty of sunlight.
- Choice of solar panels: The kind of solar panels you buy will affect your total cost. High-efficiency monocrystalline panels will cost more upfront but can also save you more money over the lifetime of your system. If space isn't a constraint for your project, you can opt for a higher number of more affordable panels.
- Energy consumption: Installing a solar system may be too pricey an option for households that don't use a lot of energy per month.
- Incentives: The federal solar investment tax credit, which everyone qualifies for, allows you to deduct 30% of the cost of your solar system installation from your taxes. Additionally, not including incentives, you can save about $16,000 over 20 years on your energy bills.
Due to solar panels now being cheaper than ever as well as several solar incentives, they are a sound investment for many homeowners.

Solar Incentives in Fairfield
Since solar power is better for the environment than burning fossil fuels, there are a number of government incentives available to encourage people to make the switch. On top of the federal tax credit incentive, there are also some state- and city-level incentives, which in the majority of cases, stack with the federal incentive, so you get to save even more. Our article on solar incentives goes over more information on the incentives you can benefit from in Fairfield.
Environmental Impact of Switching to Solar in Fairfield
If you're planning on adding solar panels to your home, one of the major reasons why may be to lower your greenhouse gas emissions. But how much can switching to solar actually help the environment? The amount of energy you use is an important factor to consider. The more power your household consumes, the greater your impact when you go solar. If you go solar, your carbon dioxide emissions can be cut by about 100 pounds each year. If you want to do what you can for the environment, you'll likely get that there are many good things about adopting solar power other than just saving money on electricity. You can also help protect the environment, which some would argue is priceless.
