Does Sunpower Operate In My State How Do I Order
SunPower operates in all 50 states.
SunPower has an online tool that lets you get an idea of your solar array’s appearance and your estimated savings. You do have to provide contact information. The estimated array for my home seemed to include panels on a small walkout balcony, so it’s a bit of a blunt object.
To get a quote, fill out a short form on SunPower’s website, which will prompt a call or email from a solar advisor. You’ll work to design your solar system with a SunPower employee, which will require 12 months of electricity bills. This often takes place online, SunPower said, though conducting the meeting in person is an option. Once you’ve reached an agreement, a site visit does occur to check the condition of your roof and electrical panel.
Online, you get very little information about your potential costs before you have to provide contact information. This is fairly common, and companies that do offer upfront cost information offer only rough estimates.
SunPower operates in all 50 states.
SunPower works with both in-house installation teams and dealers around the country to install their panels.
How To Find The Best Price On Your Solar Panels
If you want the best solar panels for your home, youre going to pay a higher price.

What Is A Solar Panel
Solar panels are made up of silicone cells, which is the magic component for turning sun-rays into energy. Some panels will have a single, solid silicone cell , while others will have pieces of silicone that have been melted together . These cells are then fixed inside a frame, and covered with a protective glass.
When the panel is properly angled, it will capture sun-rays and convert it into DC energy. In turn, the DC energy gets converted to AC energy via an inverter, which you can use inside the home for your loads.
Best Solar Panels Ranked By Temperature Coefficient
A solar panels temperature coefficient measures how much or little a panels production is lowered in hot temperatures. Based only on the lowest temperature coefficient available in a panel , here are the top five best solar panel manufacturers:
Best solar panels by temperature coefficient
| Rank | |
|---|---|
| SunSpark Technology | -0.28 |
Solar panels are like any other electronic equipment: they operate most efficiently when kept cool . The temperature coefficient gives you a sense of how your panels performance will degrade during hot summer days. For every degree above 25° C , your solar panels electricity production will decrease by the temperature coefficient. A lower temperature coefficient is better.

Efficiency By Type Of Solar Panel
The efficiency rate depends mainly on the type of solar panel you use. Monocrystalline solar panels are currently the most efficient and cost-effective option for a solar energy system and the type of solar panel companies most commonly offer. However, polycrystalline or thin-film solar panels may be a better fit for your home if you have more roof space or require limited energy for your solar project. Weve broken down the pros and cons of each panel type below.
Features an average efficiency of 10% to 20%
Tends to be the least expensive option
Features a high heat tolerance compared to both monocrystalline and polycrystalline solar panels
Cons
Efficiency ratings vary significantly according to the type of material used in the panel
Less durable than other types of panels
Requires the most amount of roof space to perform well

How To Find The Best Price On Sunpower Solar Panels
SunPower panels are, without a doubt, some of the best solar panels available today. When EnergySage ranked the best solar panels on the market, our SunPower reviews were the highest of any panel brand. If you have a limited amount of space and need to maximize your solar panel systems production, you cant go wrong with an installation that includes SunPower solar panels. However, not every homeowner needs the most efficient panels available on the market. If you have enough space for a larger system, installing slightly less efficient panels may give you the performance you need at a slightly better price.
The best way to determine whether SunPower solar panels are the best solar panels for your home is to review multiple quotes with different solar equipment options before making a decision. When you compare all of your options on the EnergySage Marketplace, youll find the right combination of price and quality that meets your needs. When registering, simply note in your profile that youre interested in receiving quotes that include SunPower solar panels for your home.

What Is The Typical Performance Advantage Gained From Using Sunpower Maxeon Panels
A SunPower Maxeon solar panel delivers up to 25% more energy than a Conventional Panel in its first year of operation. In year 25, the difference would grow to about 35% more energy, for an average of 30% more energy during the first 25 years1SunPower Maxeon compared to a Conventional Panel on same-sized arrays .

Sunpower Solar Panel Efficiency
The first solar panel ever invented only had about a 6% efficiency rate meaning only 6% of the energy striking the panel is converted into usable alternating current electricity. Even today, the most efficient solar panels in development only convert about 40% at the very most.
SunPowers ratings of 19-22% are significantly higher than most conventional panels on the market today, providing a variety of benefits. These include:
- Requiring a lower overall cost: Since high-efficiency solar panels have a better power output, the amount of home solar panels you need is reduced, which can lead to lower total costs.
- Providing more power for the usable space: Along the same lines,high-efficiency panels provide more energy potential with less space. This means homeowners with less available roof space can still be good candidates for SunPower solar panels.
- Being more sustainable overall: Not only dohigh-efficiency panels provide more bang for your buck, but they also help to lower your impact. Fewer panels require fewer materials, therefore reducing the energy and waste that goes into your SunPower system.

How Much Do Sunpower Maxeon Panels Cost
With solar, as with many things, you get what you pay for. Not all solar systems are alike. The quality of the technology matters in the long run. The durability, reliability and efficiency of solar panels can vary widely by manufacturer. If you settle for Conventional Panels that might cost less out-of-pocket, you can expect to see average results and less savings over time.
A higher quality panel like SunPower Maxeon might cost a little more up front, but you will see more predictable performance in the long run. SunPower Maxeon panels generate more energy, last longer, are backed by a stronger warranty, and are produced more sustainably than Conventional Panels. This means SunPower Maxeon panels will offset more of your electricity bill, saving you more, and do so with the peace of mind you expect from a top-quality product.
What Portable Solar Technologies Do Sunpower Solar Panels Use
The SunPower Modules are using Maxeon solar cell technology. The significant difference in this form of the cell is the uninterrupted cell formation.
A conventional solar cell has busbars to capture the cell’s energy.
The Maxeon technology eliminates these metallic busbars from the cell’s surface and replaces them with a copper backing to assemble the power, giving the whole-cell face to electricity generation.
This kind of cell allows SunPower to attain its phenomenal 22% panel efficiency rating with its high-powered monocrystalline panel.
