Factors that Affect Solar Panel Costs in Nassau
Cost is typically one of the most important factors for homeowners who want to invest in solar. There are a few primary factors that affect your total cost in Nassau: solar equipment and system size, financing options and the solar installation company you choose. We’ll go over each of these briefly below.
Solar Equipment
Solar system size, which is measured in kilowatts, is one of the largest factors that affects the overall cost of installing solar panels. For that reason, it’s important to accurately assess the size of the solar energy system needed for your home by figuring out your energy needs.There are a lot of different solar panel brands and the one you choose also affects the cost. Typically, the brands that offer higher efficiency tend to also be more expensive. Plus, the type of equipment you want to install can affect your total cost. If you just need panels, your system will be far less expensive than if you also need solar batteries or an electric vehicle charger.
Solar Financing Terms
If paying for solar panels out of pocket is too expensive, solar loans are an affordable option because they cut back your upfront costs and let you pay for your system over a term of, on average, between five and seven years.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 original cost. Making a larger down payment or finding a solar loan with a low interest rate could reduce your costs remarkably.
Solar Panel Installation Company
Lastly, the company you get to install your solar panel system can impact how much you pay. Nassau’s solar companies all have different labor costs and add varying upcharges to equipment. Larger national companies typically have lower costs, but some local companies compete 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 vehicle charger installation, they might be cheaper overall.

How to Save on Solar Panels
The solar panel company you opt for will be a major factor in determining not only your overall costs, but also the types of solar panel brands, warranties, and other equipment you have access to. When choosing a solar company, there are some important things you should keep in mind, such as:
- Warranty: Many companies offer different kinds of warranties that cover different things. A 25-year, all-inclusive warranty is the gold standard.
- Contract: Although reading through a contract can take a lot of time, it’s important to do it carefully so you can be sure you understand how much the equipment and services will cost and how part repairs and replacements will be handled.
- Solar Panel Brands: The kind of solar panel you need plays a part in which company you should go with, since different companies have different panels.
- Installation Process: An important thing to understand when going solar is the installation process itself. Be sure to clarify any details you should know with your solar installer, such as what permits you should secure and how long the project will take.

EcoWatch's Nassau, NY Solar Cost FAQs
What is the average cost of installing solar panels in Nassau?
The average cost of solar panels in Nassau is about $18,250 for a 5-kW system and $36,500 for a 10-kW system before the ITC, but the actual cost will depend on stuff such as the model of solar panels you want, what size system you need and how much energy you consume.
Should I lease or buy solar panels in Nassau?
Leasing solar panels can be an attractive choice, as it commonly 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.
Is switching to solar power worth it?
Whether or not solar panels are worth it depends on a variety of factors like local electricity rates and how much direct sunlight your roof gets.
How often do you have to replace solar panels?
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 the amount of energy they produce will have decreased significantly after that point. You can decide to replace them after having them for that long or you can keep using them at a lower efficiency.
