Factors that Affect Solar Panel Costs in Greenwich
Though the average cost of a solar system in Greenwich is $9,307, your actual cost may be above or below the average. There are many factors that can have a sizable impact on the cost of a solar system installation. Below are some of the more important things to keep in mind.
Solar Equipment
The size of the solar system you need for your home, which is measured in kilowatts, is the most significant cost factor to consider. For every additional kilowatt you need, your total will most likely increase by around $2,770. There are a lot of different solar panel brands and the one you pick also affects the cost. In many cases, the brands that offer higher efficiency tend to also cost more. In addition, the type of equipment you're looking to get can affect your total cost. If you only need panels, your system will be far less expensive than if you also need solar batteries or an electric vehicle charger.
Solar Financing Terms
Solar panels can save you money on energy bills over many years, but they can also be a big investment. That's why many Greenwich homeowners choose to finance their solar panel systems to offset upfront costs. However, the interest on solar loans also adds to your overall costs, so it's important to consider that as well. You can always reduce the total you pay in interest and sometimes even your APR by putting more money down.
Solar Panel Installation Company
Lastly, the company you opt for to install your solar system can affect your pricing. Greenwich's solar companies all have different labor costs and add varying upcharges to equipment. Larger national companies generally have lower costs, but some local companies undercut them by promoting sales and discounts. While the smaller companies might not have access to specific equipment options like Tesla Powerwall batteries or add-on services like electric vehicle charger installation, they might be cheaper overall.

How to Save on Solar Panels
There are many solar installers to choose from, all of which offer different warranties, solar panel brands and price points. To help you pick the right company for you, here are some tips to keep in mind:
- Contract: Before you sign a contract with a solar company, make sure to look it over fully so you understand the terms. Also, ask questions if you aren't sure about some of the terms, such as what to do if a part breaks or malfunctions and if there are any guarantees about energy production.
- Reputation: Make sure your solar system installer has a good reputation by confirming it has certifications and licenses, checking its number of years in business and reading reviews by past customers and solar experts like the EcoWatch team.
- Solar Panel Brands: Not all solar companies carry the same brands of solar panels, so the brand and type of panel you want can play a big role in the company you go with.
- Installation Process: Make sure you're aligned with the installer regarding how the installation process will go and what needs to be done before your solar panels are installed, such as updating your electrical system or roof.
