Factors that Affect Solar Panel Costs in Stonington

Cost is often one of the most important factors for homeowners who want to invest in solar. There are a few key factors that determine your overall cost in Stonington: 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 electricity your household uses, the larger your system will likely need to be. You can expect to spend around $2,800 per kilowatt in Stonington. The type of solar panels and equipment you want is another factor that will greatly influence costs. Solar panels that have higher efficiency, like monocrystalline panels, tend to be more costly. Moreover, solar equipment consists of more than just the solar panels themselves. You'll also need to make decisions 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 looking for a solar system that falls within your budget.

Solar Financing Terms

Most solar companies in Stonington offer solar loans, which reduce your upfront costs of installing a solar system. It's wise to add the interest you'll pay in your final cost estimate. If you can afford to put more money down upfront, you can reduce your total costs and how long it'll take to pay off the loan.

Solar Panel Installation Company

The last significant cost factor you should keep in mind is the installer you choose. Given the booming popularity of green energy solutions in Stonington, you'll have a great number of options to choose from, but each comes at varying price points for labor and equipment. You may notice national solar installers that have lower prices due to their larger brand name and access to bulk equipment pricing, or you might see small, local installation companies offering deals or promotions to compete with those larger companies.

How to Save on Solar Panels

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

  • Installation Process: When going solar, it's essential to keep an open line of communication with your solar panel installer. Confirm that you understand how the installation process will go and the project completion timeline.
  • Reputation: Make sure your solar system installer has a good reputation by confirming it has certifications and licenses, checking how long it's been in business and reading reviews by previous customers and solar experts like EcoWatch.
  • Solar Panel Brands: Different companies offer different brands and kinds of panels. If you prefer a specific brand, make sure the solar panel installer you're considering has it.
  • Contract: Look through the contract terms thoroughly to make sure you understand the total cost, project timeline incentives and warranties.

EcoWatch's Stonington, CT Solar Cost FAQs

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

This is a tough question to answer exactly, because the cost depends on a few different 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 extra solar equipment or higher quality panels, or if you have above-average energy needs. Conversely, you can spend less if you want a smaller solar panel system or less efficient solar panels.

Is cost the most important consideration when buying solar panels?

Cost is a crucial factor to consider, but whether it's the most important for you depends on why you decided to go solar. In cities where rooftop space is limited, efficiency can trump the cost. Other factors that are important to be mindful of are the quality and durability of your solar panels.

Can solar panels completely eradicate my electricity bills?

It is possible to eradicate your electricity bills with solar panels, but for most homeowners in Stonington, that will require at least a 10-kW system. Not all homes will have the roof space for that size system, so you'll want to check with a local solar installer to see how many panels can fit on your roof.

What solar power system size is right for my home?

To figure out what solar panel system size you need, you need to know how much energy your home requires and how much sunlight your home gets. For a general estimate, however, since each panel can usually produce about 250 to 400 watt-hours per hour, the average house will need 20 to 35 panels.
