Factors that Affect Solar Panel Costs in Wilton

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 panels.

Solar Equipment

The cost of solar panels varies by thousands of dollars due to some different factors. One of the most significant factors is the system size, which is measured in kilowatts (kW). Solar power systems that have better efficiency or power generation need better technology and/or more equipment, both of which can increase costs. For each additional kilowatt you need, your cost can go up by about $2,910. Some solar brands — like Maxeon from SunPower — cost more upfront but also tend to offer higher efficiency. In a city like Wilton, where sunlight isn't as abundant, efficiency can quickly pay off. Also, if you have a small roof or limited 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 Wilton to be too expensive, even if the investment pays off over time. Thankfully, almost every solar installer in the area provides financing options. Solar loans substantially decrease upfront costs in most cases, but they also result in higher prices over time due to interest. It's wise to factor 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 the amount of time it'll take to pay off the loan.

Solar Panel Installation Company

A final factor to keep in mind when trying to estimate the cost of solar for your home or business in Wilton is the company you hire to install your PV system. As with choosing a company to build a deck or pool, for example, you'll have many options for solar installers that provide a range of services for different budgets. You may notice national solar installers that have lower prices due to their larger brand name and access to bulk equipment prices, 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 numerous companies to choose from in Wilton, and some homeowners feel overwhelmed considering their options. Selecting the right company for you can be difficult, so here are some tips to help you decide:

  • Warranty: If you're worried about the durability of your solar panel system, verifying that your company offers a 25-year, all-inclusive warranty can help put you at ease.
  • Contract: It's important to look over your solar installer's contract well to understand what services they will provide, what the warranty covers and what you can expect about your solar system's energy production.
  • Reputation: Long-standing companies likely have a high reputation. This is important because it ensures that it will not only see your solar project through, but will also provide quality aftercare and customer support, such as part repairs and replacements.
  • Solar Panel Brands: Different companies will carry different brands and models of panels. If you want a specific brand, make sure the solar panel installer you're considering has it.

EcoWatch's Wilton, NH Solar Cost FAQs

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

This is a difficult question to answer precisely, because the cost depends on many factors. Generally speaking, it costs about $14,550 for a 5-kW system and $29,100 for a 10-kW system after the ITC is applied. You can expect to pay more if you want additional solar equipment or more efficient panels, or if you have above-average energy consumption. On the other hand, you can spend less if you opt for a smaller solar panel system or cheaper solar panels.

Is cost the most important thing to consider when buying solar panels?

The upfront cost is a crucial factor to consider, but whether it's the most important for you depends on your reasons for going 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 eliminate my power bills?

It is possible to eradicate your electricity bills with solar panels, but for most homeowners throughout Wilton, 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 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 stop working completely at that time. What this means is their energy production will have decreased significantly after that point. You can decide to replace them once you've had them for that long or you can keep using them at a lower efficiency.
