Factors that Affect Solar Panel Costs in Killingworth

The cost of installing a solar system in Killingworth can vary by more than $10,000 from home to home. Your actual cost depends on several factors. The largest one is your system size, and other factors include equipment choices, financing options and the solar installer you choose.

Solar Equipment

The size of the solar energy system you need for your home, which is measured in kilowatts, is the most significant cost factor to consider. For every additional kilowatt you need, your total will most likely increase by around $2,800. The type of solar equipment you choose can bring your price up or down by thousands or even tens of thousands of dollars. If you get the most efficient solar panel brands, you'll end up paying more upfront than if you opted for the most affordable panels. However, more efficient panels could save you more over time on your energy bills. Additionally, add-on products, like solar batteries, can bring your total well above the Killingworth average.

Solar Financing Terms

Many homeowners find the average cost of solar in Killingworth to be prohibitively expensive, even if the investment pays off over time. Fortunately, almost every solar company in the area provides access to financing options. Solar loans drastically decrease upfront costs in most cases, but they also lead to paying more over time due to interest. When considering your overall cost, you should also calculate the interest you'll pay if you go with a solar loan. Also, paying a higher down payment can reduce the total interest paid over time.

Solar Panel Installation Company

The solar installer you go with to handle your switch to green energy can have an effect on your total costs. There are about 3 solar panel companies in Killingworth, and each can charge varying amounts for labor and equipment. The company's size sometimes plays the most considerable role in your costs. Larger national companies, like SunPro and Sunrun, often have lower prices because of greater resources and better pricing. Smaller local companies might be more costly, but they generally have better customer service and more customization options, and the occasional sale or promotion can bring their pricing down to compete with bigger companies.

How to Save on Solar Panels

The solar installer you opt for will be a major factor in determining not only your overall costs, but also the kinds of solar panel brands, warranties, and other equipment you can get. When choosing a solar company, there are several important things you should consider, including:

  • Contract: It's important to look over your solar installer's contract fully to understand what services they will provide, what the warranty covers and what expectations you should have about the project timeline.
  • Solar Panel Brands: Different companies will have different brands and models of panels. If you prefer a specific brand, make sure the solar installer you're considering has it.
  • Reputation: Your solar installer should have a good reputation as a company and have verifiable expertise in the field. Two ways to check this are to look for whether a company has technicians certified by the North American Board of Certified Energy Practitioners (NABCEP) and if it has positive reviews from previous customers.
  • Installation Process: An important thing to understand when adopting solar power is the installation process itself. Be sure to align on any details you need to know with your solar company, such as what permits you should secure and how long the project will take.

EcoWatch's Killingworth, CT Solar Cost FAQs

What is the average cost of installing solar panels in Killingworth?

This is a hard question to answer exactly, because the cost depends on many factors. Generally speaking, it costs about $14,000 for a 5-kW system and $28,000 for a 10-kW system after the ITC is applied. It will be more expensive if you want additional solar equipment or more efficient panels, or if you have above-average energy needs. On the flip side, you can spend less if you want a smaller solar panel system or cheaper solar panels.

Should I lease or buy solar panels in Killingworth?

Leasing solar panels can be an attractive choice, because it often comes with low or $0 upfront payments. The downside is that you won't be able to save as much. If you lease, you don't own the system, so you can't claim any incentives and your home value won't increase. Buying solar panels is a better way to go if you want to get the most savings.

Can you sell solar power back to the grid in Killingworth?

The majority of states have net metering programs of some kind. Through these, you can be compensated for the extra power your system generates or or receive credits to put toward future utility bills. Currently there are just three states that don't have any net metering laws: Alabama, Tennessee and South Dakota.

How long do solar panels last in Killingworth?

Although the average lifespan of solar panels is 25 to 30 years, that doesn't mean they are completely unusable at that time. What this means is the amount of energy they produce will have decreased significantly after that point. You can choose to replace them once you've had them for that long or you can keep using them at a lower efficiency.
