Factors that Affect Solar Panel Costs in Killingly
There are many factors that can determine your solar panel installation cost, such as the size of your system, the equipment you choose, your financing options and the specific company that performs the installation.
Solar Equipment
When it comes to estimating the cost of a solar system in Killingly, one of the most important factors is the size of the system you need. Solar systems are sized by kilowatts (kW) and are mainly based on your home’s energy usage, which you can gauge by looking at past power bills. Your overall cost can increase by about $3,750 for each additional kilowatt you need.The brand and type of equipment you choose for your solar system can raise or lower the price quite significantly. If you prefer a trusted brand name like Tesla or SunPower, these often have a higher price tag than other brands. Efficiency also matters. Whether you’re opting for high efficiency because you have a small roof or just want maximum energy production, you can expect a higher equipment cost, but this can typically lead to greater savings over time. Plus, if you want additional equipment like an electric vehicle charger or solar batteries, this will also increase the cost.
Solar Financing Terms
For some homeowners, paying for solar panels out of pocket can be a challenge. Solar loans are available from most installers in Killingly, which can bring down, or in some cases eliminate, your upfront costs to make solar more accessible.When considering your overall cost, you should also calculate the interest you’ll pay if you decide on a solar loan. Also, paying a higher down payment can lower the total interest paid over time.
Solar Panel Installation Company
The solar company you choose will impact your total cost to adopt solar power. Different companies will bill different amounts for the equipment and labor.Companies that only sell products with high efficiency and therefore a higher price point — 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 has the products, warranties and services you want and also is within your budget.

- Installation Process: Make sure you’re on the same page with the installer regarding how the installation process will go and what needs to be done before your solar panels are installed, such as updating your electrical system or roof.
- Warranty: Warranties that provide coverage for defective panels and repairs over a long period of time such as 25 years are the best you can get in the business, and offering such a warranty is one mark of a quality company.
- 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 do the job well. Another way you can look into your installer’s reputation is by reading reviews.

EcoWatch's Killingly, CT Solar Cost FAQs
How much does it cost to install solar panels in Killingly?
This is a tough question to answer exactly, because the cost depends on a variety of factors. Broadly speaking, it costs about $18,750 for a 5-kW system and $37,500 for a 10-kW system after the ITC is applied. You can expect to pay more if you want additional solar equipment or higher quality panels, or if you have higher-than-average energy consumption. On the other hand, you can spend less if you choose a smaller solar panel system or less expensive solar panels.
Is it better to lease or buy solar panels in Killingly?
Leasing solar panels can be an attractive choice, as it usually comes with low or $0 upfront payments. The drawback 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 tax rebates and credits and your home value won’t increase. Buying solar panels is a better way to go if you want to maximize your savings.
Do solar panels increase your home value?
Solar panels can increase your property’s value remarkably as long as you buy or finance your panels and don’t choose a solar lease or power purchase agreement (PPA). According to research done by Zillow, the average home value increases by about 4.1% with a solar installation."
How often do you have to replace solar panels?
Even though 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 replace them after having them for that long or you can continue to use them at a lower efficiency.
