Factors that Affect Solar Panel Costs in Fairfield

There are a number of criteria that can influence your solar panel installation cost, such as the size of your system, the equipment you choose, your financing options and the specific company that installs your solar panels.

Solar Equipment

The cost of solar panels varies by thousands of dollars due to a variety of factors. One of the notable factors is the system size, which is measured in kilowatts (kW). Solar power systems with greater efficiency or power production require better technology and/or more equipment, both of which can raise costs. For each additional kilowatt you need, your cost can go up by about $2,730. Some solar panel brands — like Maxeon from SunPower — are more expensive upfront but also tend to offer higher efficiency. In a city like Fairfield, where sunlight is abundant, efficiency can quickly pay off. In addition, if you have a small roof or you don't have a lot of 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

Solar panels can save you money on energy bills over time, but they can also be a significant investment. That's why many Fairfield homeowners opt to finance their solar panel systems to offset upfront costs. While solar loans make going solar more accessible for Fairfield homeowners, they can also raise the total you pay for your system, depending on your interest rate. If you make a larger down payment, though, you can avoid paying as much in interest.

Solar Panel Installation Company

A final factor to keep in mind 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. As with choosing a company to renovate your kitchen, for instance, there's no shortage of solar installers that provide a range of services at different price points. Larger national companies typically have lower costs, but some local companies compete with them by offering sales and discounts. While the smaller companies might not have specific equipment options like Tesla Powerwall batteries or add-on services like electric car charger installation, they might be cheaper overall.

How to Save on Solar Panels

There are a lot of solar installers to choose from, all of which offer different warranties, solar panel models and price points. To help you find the right company for you, here are some tips to keep in mind:

  • Contract: It's important to look over your solar installer's contract thoroughly to understand what services they will provide, what the warranty covers and what expectations you should have about the project timeline.
  • Installation Process: An important thing to understand when going solar is the installation process itself. Be sure to align on any details you should know with your solar company, such as what permits you should secure and what the project timeline is.
  • Solar Panel Brands: The kind of solar panel you need to install plays a role in which company you should choose, since different companies offer different panels.
  • Reputation: Companies that have been in business for many years likely have a high 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 support, such as part repairs and replacements.
