Factors that Affect Solar Panel Costs in Nassau
Cost is usually one of the most important factors for homeowners who are considering investing in solar. There are a few major factors that will push your cost above or below the average in Nassau: solar equipment and system size, financing options and the solar installation company you choose. We’ll cover each of these briefly below.
Solar Equipment
System size, which is measured in kilowatts, is one of the largest factors that affects the overall cost of installing solar panels. That’s why it’s important to accurately gauge the size of the solar energy system needed for your home by figuring out your typical energy use.Some solar panel brands — like Maxeon from SunPower — are more costly upfront but also tend to offer better efficiency. In a city like Nassau, where sunlight isn’t as abundant, efficiency can quickly pay off. Also, if you have a small roof or you don’t have a lot of space for your panels, higher efficiency options will be a better option. Additional equipment like electric vehicle chargers and solar batteries will also increase the cost.
Solar Financing Terms
Most solar companies in Nassau offer solar loans, which reduce your upfront costs of installing solar.Even though solar loans make adopting solar energy more accessible for Nassau homeowners, they can also add to the total you pay for your system, depending on your interest rate. If you put down a larger down payment, though, you can avoid paying as much in interest.
Solar Panel Installation Company
The solar company you select will play a role in your total cost to adopt solar power. Different companies will bill different amounts for the equipment and labor.Larger national companies generally 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 add-on services like electric vehicle charger installation, they might be cheaper overall.

- Warranty: A quality company stands out from other companies by providing the gold standard warranty — a 25-year, all-inclusive warranty covering parts, labor and performance.
- Contract: Look through the contract terms thoroughly to make sure you understand how much it will cost, project completion timeline rebates and warranties.

EcoWatch's Nassau, NY Solar Cost FAQs
How much does it cost to install solar panels in Nassau?
This is a hard question to answer precisely, because the cost depends on a variety of factors. Broadly speaking, it costs about $18,250 for a 5-kW system and $36,500 for a 10-kW system after the ITC is applied. It will be more expensive if you want extra solar equipment or more efficient panels, or if you have higher-than-average energy consumption. On the other hand, you can spend less if you choose a smaller solar panel system or less efficient solar panels.
Should I lease or buy solar panels in Nassau?
Leasing solar panels can be an option if you can’t pay upfront or get a solar loan, but since you don’t own the system, you can’t take advantage of many solar incentives. Also your home value won’t increase, so you’ll have less savings over time. If you can afford to buy a solar system upfront, then buying is the better option if you want the most savings from going solar.
Is it worth going solar in Nassau?
Solar panels can be a beneficial investment for many homeowners, but they might not be worth it for everyone. If your home doesn't get enough sunlight and/or your power bills are already reasonably low, solar panels might not be for you.
How often do you have to replace solar panels?
On average, the lifespan of solar panels is about 25 to 30 years. Some even last up to 50 years, but their efficiency decreases by about 0.8% each year. You can choose to replace them sooner if you want to maintain a larger amount of energy production.
