Factors that Affect Solar Panel Costs in Fairfield
Cost is typically one of the most important factors for homeowners who are considering investing 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 go over 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 uses, the larger your system will likely need to be. You can expect to pay about $3,760 per kilowatt in Fairfield.The brand of solar panels and equipment you choose is another factor that will greatly influence costs. Solar panels that are more efficient, like monocrystalline panels, tend to come at a higher price. Moreover, solar equipment goes beyond just the solar panels themselves. You’ll also need to think about the kind of racks used to mount the panels, inverters, solar batteries, etc. It’s important to take all of this into consideration when searching for a solar system that’s in your budget.
Solar Financing Terms
Solar panels can save you money on energy bills over many years, but they can also be a significant investment. That’s why many Fairfield homeowners decide to finance their solar panel systems to make paying for solar more affordable.When figuring out your overall cost, you should also calculate the interest you’ll pay if you choose to go with a solar loan. Also, paying more on your down payment can reduce the total interest paid over time.
Solar Panel Installation Company
The final significant cost factor you should take into consideration is the installer you choose. Given the booming popularity of clean energy solutions in Fairfield, you’ll have a great number of options to choose from, but each comes at various price points for labor and equipment.The company’s size sometimes plays the most considerable role in the cost of installation. Larger national companies, like SunPro and Sunrun, often have lower prices because of more resources and bulk pricing. Smaller local companies might be more costly, but they can sometimes have better customer service and more customization options, and the occasional sale or promotion can bring their pricing down to compete with bigger companies.
