Factors that Affect Solar Panel Costs in Fairfield

For many Fairfield homeowners, the decision to adopt solar energy rests on cost. However, the range of solar installation costs can be quite wide in Fairfield, with typical prices between $20,000 to $40,000. There are several factors that significantly influence the price you'll pay, which we'll go over below.

Solar Equipment

The size of the solar panel system you need, which is measured in kilowatts, is the most important cost factor to consider. For every additional kilowatt you need, your total will most likely increase by nearly $2,730. Some solar panel brands — like Maxeon from SunPower — cost more upfront but also tend to offer higher efficiency. In a city like Fairfield, where sunlight is relatively abundant, efficiency can quickly pay off. Plus, if you have a small roof or limited space for your panels, higher efficiency options will be more impactful. Additional equipment like electric vehicle chargers and solar batteries will also increase the cost.

Solar Financing Terms

If paying for a solar system in cash is difficult, solar loans are a popular option because they reduce your upfront costs and let you pay for your system over a term of, on average, between five and seven years. You'll have to consider the long-term cost of loans, including the total interest you'll pay over the length of the loan. If you're only able to get a high-interest loan, then your total can be hundreds or even thousands of dollars more than the original cost. Making a larger down payment or securing a solar loan with a low APR could reduce your costs significantly.

Solar Panel Installation Company

A final consideration when trying to figure out the cost of solar for your home or business in Fairfield is the company you choose to install your PV system. Similar to choosing a company to renovate your kitchen, for instance, you'll have no shortage of solar installers that offer a range of services for different budgets. Companies that only sell high-quality, high-efficiency and high-price products — like Maxeon solar panels from SunPower or Tesla Powerwall batteries — so choosing those installers will generally cost more. It's best to do some research and go with the company that provides the products, warranties and services you want and also fits within your budget.

How to Save on Solar Panels

The company that does your solar system installation will affect the warranties and brands available to you, and it will also have an impact on your total cost. Because picking a company can be difficult, we have some tips to help you, such as:

  • Reputation: Companies that have been operating for many years likely have a good reputation. This is important because it ensures that it will not only see your solar installation through, but will also provide quality aftercare and customer service, such as part repairs and replacements.
  • Contract: It's important to look over your solar installer's contract well to understand what services they will provide, what the warranty covers and what expectations you should have about your solar system's energy production.
  • Warranty: An all-inclusive, 25-year warranty can help keep your solar system running for a long time and save you money on repairs and maintenance.
  • Solar Panel Brands: Different companies have various brands and models of panels. If you want a specific brand, make sure the solar panel installer you're considering has it.

The average cost of solar panels in Fairfield is about $13,650 for a 5-kW system and $27,300 for a 10-kW system before the ITC, but the actual cost will depend on certain factors such as the type of solar panels you want, what size system you need and how much energy you consume.

The exact number of solar panels you need depends on your household energy usage and the average daily sunlight your roof gets.
