Factors that Affect Solar Panel Costs in Old Greenwich
Though the average cost of a solar system in Old Greenwich is $11,749, your actual cost may differ. There are several factors that can have a major impact on the cost of a solar panel installation. Below are some of the more crucial things to consider.
Solar Equipment
One of the most important factors to consider when it comes to the cost of adopting solar energy is the size of the solar system, which is measured in kilowatts (kW). The more power your household consumes, the larger your system will likely need to be. You can expect to pay around $3,750 per kilowatt in Old Greenwich.Some solar brands — like Maxeon from SunPower — are more expensive upfront but also tend to offer better efficiency. In a city like Old Greenwich, where sunlight is relatively abundant, efficiency can quickly pay off. Also, if you have a small roof or you don’t have a lot of space for your panels, higher efficiency options will be more impactful. Additional equipment like electric vehicle chargers and solar batteries will also increase the cost.
Solar Financing Terms
Many homeowners find the average cost of solar in Old Greenwich to be prohibitively steep, even if the investment pays off over time. Thankfully, nearly every solar company in the area offers financing options. Solar loans drastically decrease upfront costs for most homeowners, but they also result in a higher cost over time due to interest.You’ll have to consider the long-term cost of financing options, including the total interest you’ll pay over the length of the loan. If you can only get a high-interest loan, then your total can be hundreds or even thousands of dollars more than the principal cost. Making a larger down payment or finding a solar loan with a low APR could reduce your costs considerably.
Solar Panel Installation Company
The final key cost factor you should keep in mind is the installer you choose. Given the booming popularity of sustainable energy solutions in Old Greenwich, you’ll have lots of options to choose from, but each comes at different price points for labor and equipment.Additionally, some companies in Old Greenwich are more knowledgeable about local solar incentives and can help you learn about additional rebates or tax exemptions. However, they may charge more for that service. Even if they cost more upfront, they could help you save more money in the long run.

How to Save on Solar Panels
The company that does your system installation will affect the warranties and brands available to you, and it will also have an impact on your total cost. Since selecting a company can be a challenge, we have some tips to help you, such as:
- Reputation: Solar system installers that have great reviews from their customers and that have been operating for many years in most cases offer quality solar panel installation and expertise.
- Solar Panel Brands: Homeowners will have different preferences for panels based on their locations and how much efficiency they need. Although there are many options for which type of solar panel you can get, not every company will have access to the exact one you may want or need, so make sure you ask for their list of offerings before making your decision.
- Warranty: If you care about the longevity of your solar panels, checking if your company offers a 25-year, all-inclusive warranty can help put you at ease.
- Installation Process: Make sure you’re on the same page with the company regarding how the installation process will go and what you need to do before your solar panel system is installed, such as repairing your electrical system or roof.

EcoWatch's Old Greenwich, CT Solar Cost FAQs
What is the average cost of installing solar panels in Old Greenwich?
This is a tough question to answer exactly, because the cost depends on a few different 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. It will be more expensive if you want extra solar equipment or more efficient panels, or if you have above-average energy needs. Conversely, you can spend less if you choose a smaller solar panel system or less efficient solar panels.
Should I lease or buy solar panels in Old Greenwich?
Leasing solar panels can be an appealing choice, as 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 maximize your savings.
How much can I save on electricity bills after switching to solar?
Solar panels can potentially eliminate your electricity bills depending on your location and how much sunlight your home gets. Even if it doesn’t get rid of them completely, you can save a lot of money on your bills, about $1,207.35 per year.
How often do you have to replace solar panels?
Although the average lifespan of solar panels is 25 to 30 years, that doesn't mean they stop working completely at that time. What this means is how much energy they produce will have decreased significantly after that point. You can opt to replace them after having them for that long or you can keep using them at a lower efficiency.
