Factors that Affect Solar Panel Costs in Watertown
There are many criteria that can determine your solar system installation cost, such as the size of your system, the equipment you choose, your financing options and the specific company that installs your solar system.
Solar Equipment
The size of the solar panel system you need for your home, which is measured in kilowatts, is the most important cost factor to consider. For every additional kilowatt you need, you can expect your total to increase by about $2,800. Some solar brands — like Maxeon from SunPower — cost more upfront but also tend to offer better efficiency. In a city like Watertown, where sunlight is relatively abundant, efficiency can quickly pay off. Also, if you have a small roof or limited space for your panels, higher efficiency options will be a better option. 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 Watertown to be too steep, even if the investment pays off over time. Fortunately, nearly every solar company in the area offers financing options. Solar loans drastically decrease upfront costs for most homeowners, but they also result in paying more over time because of interest. It's wise to add the interest you'll pay in your final cost estimate. If you can afford to pay a higher down payment, you can reduce your total costs and how long it'll take to pay back the loan.
Solar Panel Installation Company
A final factor to consider when trying to evaluate the cost of solar for your home or business in Watertown is the company you choose to install your solar system. Similar to choosing a company to build a deck or pool, for instance, there are plenty of solar installers that provide a range of services at different price points. Additionally, some companies in Watertown are more knowledgeable about local solar incentives and can help you learn about additional rebates or tax exemptions. However, they may charge more for walking you through the whole process. Even if they cost more upfront, they could help you save more money in the long run.

How to Save on Solar Panels
Since the type of solar panels and the installer you choose considerably influences your costs and your system's durability and efficiency, it's important to pick the right ones for you. Here are some tips to keep in mind to help with your decision:
- Reputation: The North American Board of Certified Energy Practitioners (NABCEP) is a respected certification organization for renewable energy professionals. If your solar panel installer is NABCEP-certified, it likely has a good reputation and is qualified to get the job done well. Another way you can check your installer's reputation is by reading reviews.
- Solar Panel Brands: The type of solar panel you need to install plays a role in which company you should go with, since different companies have access to different panels.
- Contract: When reading through your solar installer's contract, ask for clarification about any terms you're not sure of and make sure you understand what happens in scenarios like a system part breaking or the company going out of business.
- Installation Process: Get detailed information from your solar company about the installation process and what to expect, including when the site survey will be done and how long it will take.

EcoWatch's Watertown, CT Solar Cost FAQs
What is the average cost of installing solar panels in Watertown?
This is a hard question to answer precisely, 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 more efficient panels, or if you have higher-than-average energy needs. On the flip side, you can spend less if you opt for a smaller solar panel system or cheaper solar panels.
What other factors should I consider apart from cost when buying solar panels?
The upfront cost is a key 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 keep in mind are the quality and durability of your solar panels.
Can solar panels completely eradicate my energy bills?
It is possible to eradicate your electricity bills with solar panels, but for most homeowners in Watertown, 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 contact a local solar installer to see how many panels can fit on your roof.
How long do solar panels last in Watertown?
On average, solar panels can last about 25 to 30 years. Some even last up to 50 years, but their efficiency goes down by about 0.8% each year. You can choose to replace them sooner if you want to maintain a higher level of energy production.
