Factors that Affect Solar Panel Costs in Islip
For many Islip homeowners, the decision to go solar comes down to cost. However, the range of solar installation costs can be quite wide in Islip, with typical prices between $20,000 to $40,000. There are numerous factors that considerably influence the price you’ll pay, which we'll go over below.
Solar Equipment
The cost of solar panels varies by thousands of dollars due to some different factors. One of the major factors is the system size, which is measured in kilowatts (kW). Solar power systems that have better efficiency or power production use better technology and/or more equipment, both of which can raise costs. For each additional kilowatt you need, your cost can go up by about $3,650.Some solar brands — like Maxeon from SunPower — are more expensive upfront but also tend to offer better efficiency. In a city like Islip, where sunlight is relatively abundant, efficiency can quickly pay off. Plus, if you have a small roof or limited 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
For some homeowners, paying for a solar system out of pocket can be financially overwhelming. Solar loans are offered by most installers in Islip, which can reduce, or in some cases completely eliminate, your upfront costs to make solar more accessible.It’s a good idea to factor the interest you’ll pay in your final cost estimate. If you can afford to put more money down upfront, you can reduce your total costs and the amount of time it’ll take to pay off the loan.
Solar Panel Installation Company
The solar panel installation company you choose will impact your total cost to make the switch to solar energy. Different companies will bill different amounts for the equipment and labor.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 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
Since the kind of solar panels and the company you choose significantly influences your costs and your system’s durability and efficiency, 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: Not all solar companies carry the same brands of solar panels, so the brand and type of panel you want can play a significant role in the company you opt for.
- Reputation: Make sure your solar panel installer has a good reputation by verifying it has certifications and licenses, checking its number of years in business and reading reviews by past customers and solar experts like EcoWatch.
- Contract: When looking through your solar installer’s contract, ask questions about any terms you’re not sure of and make sure you understand what happens in scenarios like a system part breaking or if the company goes out of business.
- Installation Process: An important thing to understand when adopting solar energy is the installation process itself. Be sure to clarify any details you need to know with your solar company, such as what permits you should acquire and what the project timeline is.
EcoWatch's Islip, NY Solar Cost FAQs
How much does it cost to install solar panels in Islip?
This is a tough question to answer exactly, because the cost depends on many factors. Generally speaking, it costs about $18,250 for a 5-kW system and $36,500 for a 10-kW system after the ITC is applied. You can expect to pay more if you want extra solar equipment or higher quality panels, or if you have above-average energy needs. On the other hand, you can spend less if you go with a smaller solar panel system or less efficient solar panels.
Is it better to lease or buy solar panels in Islip?
Leasing solar panels can be an option if you are unable to pay upfront or get a solar loan, but since you don’t own the system, you don’t have access to 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 bang for your buck from going solar.
Can you sell solar power back to the grid in Islip?
Each state has some form of net metering programs except Tennessee, South Dakota and Alabama currently. Some states allow you to sell power back to the grid, but others just give you credit toward your future power bills.
How long do solar panels last in Islip?
Even though the average lifespan of solar panels is 25 to 30 years, that doesn't mean they should be disposed of at that time. What this means is their energy production will have decreased significantly after that point. You can decide to replace them once you've had them for that long or you can keep using them at a lower efficiency.
