SunPower Solar Panels on Long Island


While there are many types of solar panels available at Energy By Choice, we believe that SunPower panels are an ideal choice for those desiring maximum efficiency and style from their solar system.

SunPower Equinox™

If design flexibility is at the top of your priority list for a new solar system with the highest efficiency panels1, look no further than the SunPower Equinox™. These solar panels are the industry’s only home solar system with components designed to work together for that exact purpose—and that are designed and built by a single company!

SunPower Complete Confidence Warranty

The SunPower Complete Confidence Warranty is the most comprehensive warranty on the market; it’s the only one you’ll ever need and probably won’t use. If you experience issues with your system within 25 years of purchase for roof systems and 10 years for monitoring technology, SunPower will repair or replace the defective part for free—with no need for receipts, proof of purchase, or written claims! This warranty covers 100% of the repair or replacement costs, including labor, shipping, and parts, and fully covers the quality of the product and solar power produced.

What Makes the SunPower Complete Confidence Warranty Different Than Warranties for Conventional Systems?

With a conventional system’s warranty, each part is made and warranted by a different manufacturer, and you have to pay for things like shipping the new panels, packaging and shipping the defective panels, and a testing fee if the manufacturer doesn’t find anything defective. Additionally, you must make claims in writing, only have a short time frame to make a claim, and must present your original physical proof of purchase. But with SunPower, one company covers everything completely for free and with minimal effort on your part.

SunPower Panels


SunPower is the most efficient AC panel and inverter manufacturer in the market, and their products are not only powerful, but beautiful, as well. We believe they are the best sole-source AC modules in the world. You can install as many or as few as you want, put them where you want, and not have to worry about “balancing strings”—with normal inverters, you have to make sure there aren’t too many or too few modules per inverter. If you want to add more later, that’s a simple process, too. At the same time, they come with panel-level monitoring, so you can keep an eye on each one and see how the entire system is performing at any given time.

SunPower AC panels provide a revolutionary combination of:

  • High efficiency
  • High reliability
  • Panel-level DC to AC power conversion
  • Viability for homes with complex or shaded roofs
  • Consumption monitoring with real-time insights for intuitive home energy management

This blend of features allows almost any home to enjoy the benefits of solar electricity.

    For Qualified Customers



  • Ralph Lindenhurst

    We are extremely happy with our experience so far with Energy By Choice & Sun Power. From the sales dept. to the installation, everything went very well. Steve, Kelly, Sail & Evelyn as well as the install crew are all very knowledgeable and professional. Thank you for getting us “green” & for enabling us in the near future to tell PSE & G to take their highest energy rates in the country & stick it where the “Sun don’t shine”.

  • Glenn Huntington Station

    Sail and his crew just finished a 9.5KW sun power solar system on my house .I am very happy with the installation and in the way the job was run from start to finish. I chose Energy By Choice because of the high standard that they offered. I am sure that I made correct decision and would highly recommend them.

  • Tallyann West Babylon

    I loved the level of professionalism of all the staff from sales, to installation personal and office staff too. My panels look beautiful and the installation appears clean. I highly recommend using Energy by Choice if you are thinking about going solar. They offer the best product and service of any solar company out there.

  • The Becerra Family Huntington Station

    The whole team is very professional. Sail always answers your questions with professionalism and patience. The crew that installed our panels were on time, efficient, polite and the site was left clean. Our panels are Sunpower, made in USA, which is what we wanted. Energy by Choice were the only ones that offered these panels. Other companies told us we could not afford a system with Sunpower panels and were offering LG panels. Sail offered from the beginning the Sunpower panels. Most import of all this is a local company!

    From the start your approach was professional, and every step of the way you clearly and accurately represented the parameters of the project.
