Factors that Affect Solar Panel Costs in Greenwich

The cost of installing a solar system in Greenwich can vary by more than $10,000 from home to home. Your actual cost is determined by several factors. The most significant one is your system size, and other factors include the equipment you choose, financing options and the solar company you choose.

Solar Equipment

The cost of solar panel systems varies by thousands of dollars due to a few different factors. One of the major factors is the system size, which is measured in kilowatts (kW). Solar power systems with greater efficiency or power generation use 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 $2,770. The brand and type of equipment you get 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 more savings over time. Plus, if you want extra equipment like an electric vehicle charger or solar batteries, this will also increase the cost.

Solar Financing Terms

Most solar companies in Greenwich offer solar loans, which reduce your upfront costs of installing solar panels. When figuring out your overall cost, you should also calculate the interest you'll pay if you go with a solar loan. Also, paying a higher down payment can reduce the total interest paid over time.

Solar Panel Installation Company

A final factor to keep in mind when trying to figure out the cost of solar for your home or business in Greenwich is the company you choose to install your solar system. As with choosing a company to renovate your kitchen, for instance, you'll have no shortage of solar installers that provide a range of services at different price points. Larger national companies typically have lower costs, but some local companies keep up with them by offering sales and discounts. While the smaller companies might not have specific equipment options like Tesla Powerwall batteries or additional services like electric car charger installation, they might be cheaper overall.

How to Save on Solar Panels

Since the brand of solar panels and the installer you choose greatly influences your costs and your system's efficiency, production, and durability, it's important to select the right ones for you. Here are some tips to keep in mind to help with your decision:

  • Solar Panel Brands: Each solar panel brand and type offers varying levels of quality, longevity and energy efficiency. They will come at different costs as well. The company you choose affects which solar panel brands you have access to.
  • Contract: Before you sign a contract with a solar company, make sure to read it through carefully so you understand the terms. Also, ask questions if you're unsure about some of the terms, such as what the warranty covers and if there are any guarantees about energy production.
  • Installation Process: When making the switch to solar power, it's necessary to maintain an open line of communication with your solar company. Confirm that you understand how the installation process will go and the project timeline.
  • Reputation: Make sure your solar company 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.

EcoWatch's Greenwich, NJ Solar Cost FAQs

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

This is a hard question to answer exactly, because the cost depends on many factors. Generally speaking, it costs about $13,850 for a 5-kW system and $27,700 for a 10-kW system after the ITC is applied. It will be more expensive if you want additional solar equipment or higher quality panels, or if you have higher-than-average energy needs. Conversely, you can spend less if you go with a smaller solar panel system or less efficient solar panels.

Should I lease or buy solar panels in Greenwich?

Leasing solar panels can be an attractive choice, because it often 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 option if you want to get the most savings.

Can solar panels significantly reduce my electricity bills?

It is possible to erase your electricity bills with solar panels, but for most homeowners throughout Greenwich, 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 Greenwich?

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.
