Factors that Affect Solar Panel Costs in Holtsville
There are a number of factors that can influence your solar system installation cost, such as the size of your system, the equipment you choose, your financing options and the specific company that does the installation.
Solar Equipment
The cost of solar panels varies by thousands of dollars due to a few different factors. One of the notable factors is the system size, which is measured in kilowatts (kW). Solar power systems with 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 panel brands — like Maxeon from SunPower — cost more upfront but also tend to offer higher efficiency. In a city like Holtsville, where sunlight is relatively 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
For some homeowners, paying for solar out of pocket can be difficult. Solar loans are available from most installers in Holtsville, which can reduce, or in some cases eliminate, your upfront costs to make solar more affordable.When figuring out your overall cost, you should also calculate the interest you’ll pay if you opt for a solar loan. Also, paying more upfront can reduce the total interest paid over time.
Solar Panel Installation Company
Lastly, the company you choose to install your solar panels can impact the cost. Holtsville’s solar companies all have different labor costs and add varying upcharges to equipment. You may come across national solar installers that have lower prices because of their bigger 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
The company that does your system installation will affect the warranties and brands available to you, and it will also have an impact on your total cost. Because choosing a company can be a challenge, we have some tips to help you, such as:
- Contract: Though reading through a contract can be tedious, it’s important to do it fully so you can be sure you understand what services your solar company will provide and the terms of the warranty.
- Solar Panel Brands: The type of solar panel you’d like to install plays a part in which installer you should go with, since different companies provide different panels.
- Reputation: The North American Board of Certified Energy Practitioners (NABCEP) is a respected certification organization for clean energy professionals. If your solar panel installer is NABCEP-certified, it most likely has a good reputation and is qualified to install your solar system. Another way you can look into your installer’s reputation is by reading reviews.
- Warranty: If you’re concerned about the longevity of your solar energy system, ensuring your installer offers a 25-year, all-inclusive warranty can give you some peace of mind.
EcoWatch's Holtsville, NY Solar Cost FAQs
What is the average cost of installing solar panels in Holtsville?
This is a hard 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. It will be more expensive if you want other solar equipment or higher quality panels, or if you have above-average energy needs. On the flip side, you can spend less if you choose a smaller solar panel system or cheaper solar panels.
Should I lease or buy solar panels in Holtsville?
Leasing solar panels can be an appealing choice, because 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 option if you want to get the most savings.
Is switching to solar power worth it?
Solar panels can be a fruitful investment for most 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.
What solar power system size is right for my home?
The exact number of solar panels you need depends on your household energy consumption and the average daily sunlight your roof gets. You can take a look at your energy bills for the past year to get an idea of the solar system size you'll need. The average household has to buy between 20 and 35 panels to cover their typical energy usage.
