Factors that Affect Solar Panel Costs in Greenwich

For many Greenwich homeowners, the decision to install a solar energy system rests on cost. However, the range of solar installation costs can be quite wide in Greenwich, with typical prices between $20,000 to $40,000. There are several factors that greatly influence the price you’ll pay, which we'll go over below.

Solar Equipment

When it comes to estimating the cost of solar panels in Greenwich, one of the most important factors is the size of the system you need. Solar systems are sized by kilowatts (kW) and are primarily based on your home’s energy usage, which you can determine by looking at past electricity bills. Your overall cost can increase by around $3,750 for each additional kilowatt you need.The kind of solar equipment you choose can bring your price up or down by thousands or even tens of thousands of dollars. If you opt for the most efficient solar panel brands, you’ll end up paying more upfront than if you opted for the most affordable panels. However, more efficient panels could save you more over time on your electric bills. In addition, extra products, such as solar batteries, can bump up your total well above the Greenwich average.

Solar Financing Terms

Many homeowners find the average cost of solar in Greenwich to be prohibitively steep, even if the investment pays off over time. Thankfully, nearly every solar installer in the area provides access to financing options. Solar loans drastically decrease upfront costs in most cases, but they also lead to higher prices over time because of 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’re only able to 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 remaining key cost factor you should consider is the installer you choose. Given the booming popularity of clean energy solutions in Greenwich, you’ll have lots 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 because of 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 major players.

How to Save on Solar Panels

Since the type of solar panels and the company you choose significantly influences your costs and your system’s durability and efficiency, it’s important to pick the right ones for you. Here are some things to keep in mind to help with your decision:

  • Contract: Even though reading through a contract can take a lot of time, it’s important to do it thoroughly so you can be sure you understand what services your solar company will provide and how part repairs and replacements will be handled.
  • Warranty: A comprehensive, 25-year warranty can help keep your solar panels running smoothly and save you money on repairs and maintenance.
  • Reputation: Make sure your solar panel installer has a good reputation by confirming it has certifications and licenses, checking its work history and reading reviews by previous customers and solar experts like the EcoWatch team.
  • Solar Panel Brands: Homeowners will have different preferences for panels depending on their locations and how much efficiency they need. Although there are many options for which kind of solar panel you can get, not every company will have the exact one you may want or need, so make sure you take a look at their list of offerings before deciding.

EcoWatch's Greenwich, CT Solar Cost FAQs

How much does it cost to install solar panels in Greenwich?

The average cost of solar panels in Greenwich is about $18,750 for a 5-kW system and $37,500 for a 10-kW system before the ITC, but the actual cost will depend on certain factors like the type of solar panels you want, what size system you need and how much energy you consume.

Is it better to lease or buy solar panels in Greenwich?

Leasing solar panels can be an attractive choice, as it usually 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 tax rebates and credits and your home value won’t increase. Buying solar panels is a better way to go if you want to get the most savings.

Can you sell solar power back to the grid in Greenwich?

The majority of states have net metering programs of some kind. Through these, you can receive compensation for the extra power your system generates or or receive credits to put toward future utility bills. Currently there are just three states that don’t have any net metering laws: Alabama, Tennessee and South Dakota.

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 home will need 20 to 35 panels.
