Factors that Affect Solar Panel Costs in Thornwood

There are many factors that can play into your total installation cost, such as the size of your system, the equipment you choose, your financing options and the specific company that performs the installation.

Solar Equipment

When it comes to estimating the cost of a solar energy system in Thornwood, one of the most crucial factors is the size of the system you need. Solar systems are sized by kilowatts (kW) and are mainly based on your home's energy usage, which you can determine by looking at past energy bills. Your overall cost can increase by about $2,950 for each additional kilowatt you need. The solar equipment you choose can bring your price up or down by thousands or even tens of thousands of dollars. If you get the most efficient solar panel brands, you'll end up paying more upfront than if you opted for the most affordable panels. On the other hand, more efficient panels could save you more over time on your energy bills. Additionally, extra products, like solar batteries, can bring your total well above the Thornwood average.

Solar Financing Terms

If paying for solar panels out of pocket is too expensive, solar loans are a popular route because they decrease your upfront costs and allow you to pay for your system over five to seven years on average. 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 can only 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 APR could reduce your costs considerably.

Solar Panel Installation Company

The solar company you pick will play a role in your total cost to go solar. Different companies will bill different amounts for the equipment and labor. Some companies only sell products with high efficiency and therefore a higher price point — like Maxeon solar panels from SunPower or Tesla Powerwall batteries — so choosing those installers will generally come at a higher cost. It's best to do some research and choose a company that offers the products, warranties and services you're looking for and also fit into your budget.

How to Save on Solar Panels

There are many solar installers to choose from, all of which offer different warranties, solar panel models and price points. To help you decide on the right company for you, here are some tips to keep in mind:

  • Warranty: If you care about the longevity of your solar panel system, ensuring your installer offers a 25-year, all-inclusive warranty can give you some peace of mind.
  • Solar Panel Brands: Homeowners will have different preferences for panels based on their roof configurations and how much efficiency they need. Although there are many options for which kind of solar panel you can get, not every company will have the exact one you may want or need, so be sure to peruse their list of offerings before making your decision.
  • Reputation: Your solar installer should have a sound reputation as a company and have verifiable expertise in the field. Two ways to check this are to look for whether a company has technicians that hold a certification from the North American Board of Certified Energy Practitioners (NABCEP) and if it has good reviews from past customers.
  • Contract: It's important to read through your solar installer's contract well to understand what services they will provide, what the warranty covers and what expectations you should have about the project timeline.

EcoWatch's Thornwood, NY Solar Cost FAQs

What is the average cost of installing solar panels in Thornwood?

This is a hard question to answer exactly, because the cost depends on many factors. Generally speaking, it costs about $14,750 for a 5-kW system and $29,500 for a 10-kW system after the ITC is applied. You can expect to pay more if you want other solar equipment or higher quality panels, or if you have above-average energy needs. On the other hand, you can spend less if you want a smaller solar panel system or less efficient solar panels.

Should I lease or buy solar panels in Thornwood?

Leasing solar panels can be an option if you can't pay upfront or secure 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 Thornwood?

Each state has some kind of net metering programs except Tennessee, South Dakota and Alabama currently. Some states let you sell power back to the grid, but others just offer you credit toward your future energy bills.

What solar power system size is right for my home?

To figure out what solar panel system size you need, you should find out how much energy your home needs and how much sunlight your home gets. For a general estimate, however, since each panel can typically produce about 250 to 400 watt-hours per hour, the average home will need 20 to 35 panels.
