Factors that Affect Solar Panel Costs in Rockville Centre
Although the average cost of a solar system in Rockville Centre is $9,833, 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 consider.
Solar Equipment
The cost of solar panel systems varies by thousands of dollars due to a variety of factors. One of the most significant factors is the system size, which is measured in kilowatts (kW). Solar power systems that have better efficiency or power generation 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 Rockville Centre, where sunlight is relatively abundant, efficiency can quickly pay off. Plus, 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
If paying for a solar system out of pocket is too expensive, solar loans are an affordable option because they decrease your upfront costs and allow you to 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 loans, 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 above the equipment and labor cost. Making a larger down payment or securing a solar loan with a low interest rate could reduce your costs remarkably.
Solar Panel Installation Company
A final consideration when trying to evaluate the cost of solar for your home or business in Rockville Centre is the company you hire to install your PV system. As with choosing a company to build a deck or pool, for instance, there’s no shortage of solar installers that provide a range of services for different budgets.The size of the company sometimes plays the most significant role in the installation costs. Larger national companies, like SunPro and Sunrun, often have lower prices because of access to more resources and better pricing. Smaller local companies might be more costly, but they generally have better customer service and more customization options, and the occasional sale or discount can bring their pricing down to compete with bigger names.

How to Save on Solar Panels
There are a lot of solar installers to choose from, all of which offer different warranties, solar panel brands and price points. To help you find 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 you look it over carefully so you understand the terms. Also, ask questions if you’re unsure about some of the terms, such as what the warranty covers and if there are any guarantees about energy production.
- Warranty: If you’re concerned about the durability of your solar panels, ensuring your company offers a 25-year, all-inclusive warranty can give you some peace of mind.
- Solar Panel Brands: Homeowners will have different preferences for panels depending on their roof configurations and energy needs. While there are many options for which model of solar panel you can get, not every company will have the exact one you may want or need, so be sure to take a look at their list of offerings before deciding.
- Reputation: The North American Board of Certified Energy Practitioners (NABCEP) is a well-established certification organization for renewable energy professionals. If your solar panel installer is NABCEP-certified, it most likely has a solid reputation and is qualified to do the job well. Another way you can look into your installer’s reputation is by reading reviews.
