Factors that Affect Solar Panel Costs in Fairfield

Cost is often one of the most important factors for homeowners wanting to invest in solar. There are a few major factors that will push your cost above or below the average in Fairfield: solar equipment and system size, financing options and the solar installation company you choose. We’ll discuss each of these briefly below.

Solar Equipment

One of the most significant factors to consider when it comes to the cost of going solar is the size of the solar system, which is measured in kilowatts (kW). The more energy your household consumes, the larger your system will likely need to be. You can expect to pay about $3,470 per kilowatt in Fairfield.The type of solar panels and equipment you choose is another factor that will considerably affect costs. Solar panels that have higher efficiency, like monocrystalline panels, tend to come at a higher price. Furthermore, solar equipment goes beyond just the solar panels themselves. You’ll also need to decide on the kind of racks used to mount the panels, inverters, solar batteries, etc. It’s important to take all of this into consideration when looking for a solar system that falls within your budget.

Solar Financing Terms

If paying for a solar system in cash is too expensive, solar loans are a solid choice because they decrease your upfront costs and let you pay for your system over five to seven years on average.Even though solar loans make adopting solar energy more accessible for Fairfield homeowners, they can also increase the total you pay for your system, depending on your interest rate and how long you take to pay off the loan. If you make a larger down payment, though, you can cut back on how much interest you have to pay.

Solar Panel Installation Company

The solar company you choose to handle your switch to green energy can play a role in your total costs. There are about 3 solar installation companies operating throughout Fairfield, and each can charge varying amounts for labor and equipment.Larger national companies generally have lower costs, but some local companies compete with them by promoting sales and discounts. While the smaller companies might not have access to specific equipment options like Tesla Powerwall batteries or extra services like electric vehicle charger installation, they might be cheaper overall.

How to Save on Solar Panels

Since the model of solar panels and the company you choose significantly affects your costs and your system’s durability and efficiency, it’s important to select the right ones for you. Here are some things to keep in mind to help with your decision:

  • Solar Panel Brands: Homeowners will have different preferences for panels depending on their locations and energy needs. Although there are many options for which model of solar panel you can get, not every company will have access to the exact one you may want or need, so be sure to peruse their list of offerings before making your decision.
  • Installation Process: One of the most important things to understand when adopting solar energy is the installation process itself. Be sure to clarify any details you need to know with your solar installer, such as what permits you should secure and what the project timeline is.
  • Reputation: The North American Board of Certified Energy Practitioners (NABCEP) is a respected certification organization for sustainable energy professionals. If your solar panel installer is NABCEP-certified, it most likely has a good reputation and is qualified to get the job done well. Another way you can research your installer’s reputation is by reading reviews.
  • Warranty: Each company may offer different types of warranties that cover different things. A 25-year, all-inclusive warranty is the gold standard.
