    Sunpower Solar is a solar energy contractor with more than 30 years in the industry. Before some of the more commonly recognized solar power companies even knew about solar power, Sunpower was getting a head start in the solar industry. Sunpower acquired Blue Raven Solar, and they are all owned under the ADT branch. Therefore homeowners investing in Sunpower Solar get some really impressive benefits. In our Sunpower Solar review, we will show you what makes this company stand out from others on the market, why you should consider Sunpower solar panels, and how much you can expect to pay.

    For a look into other brands under the same ownership, read this in-depth look into Blue Raven and detailed overview of ADT Solar.

    Our Sunpower Solar Review

    Sunpower Solar got a 4.7/5 rating when we did our evaluation of the best solar technologies on the market. One of the things that helped Sunpower stand out from other options is the fact that it is available in all 50 states. Average solar system providers have availability in about 20 or 30 states. However, from California to New York and everywhere in between, you can invest in Sunpower solar systems.

    Another great benefit here is that you will have a choice as to which of the monocrystalline panels is going to be the best choice for your home. Not all high-efficiency solar panels are created the same, and the power output can change from one to the next.

    Homeowners will also have the opportunity to preview what the solar panels will look like on the roof, and this can help make HOA approval as well as system design considerably easier. With a strong 25-year warranty and a long history in the industry, this is a solar panel that you will be satisfied with, even if it does have a higher upfront cost.

    Sunpower Solar Company Profile

    Sunpower Solar is headquartered in San Jose, California, and it has thousands of employees across the United States. The Sunpower system is a bit different than others on the market as it focuses more on high-quality efficiency ratings than simply producing energy.

    Solar Services & Cost

    The exact costs of your solar system will need to be determined by a project manager from Sunpower Solar. The company does a great job in the sales process as they will allow you to see the best solar panels for your home and energy needs while also letting you preview what that will look like.

    Sunpower Solar is known as one of the more expensive solar systems on the market. This is partly because their efficient solar panels and modules are known to create a large amount of power. Sunpower customers can choose which type of solar panel they want, and it will impact the cost considerably.

    The options include:

    • M SeriesThe M Series is the highest in efficiency and price, and it is available in the 440 -420 watt range.
    • A Series: The A Series is a very popular choice that produces up to 415 watts and is used in the residential setting.
    • X Series: The X Series does not require quite as many panels but can still deliver the output you need from its efficient solar cells.
    • E Series: The E Series is more of a value based solar panel that works well for those on a budget.
    • U Series: The U Series was created for use with the SunPower Equinox® systems; this is also combined with a solar storage system to keep you prepared during a power outage.

    In addition to the main solar services and costs, the Sunpower solar power system can also include the SunVault Storage for extra energy storage as well as a charger for an electric vehicle. Sunpower works with its own products and will have product options similar to the Tesla Powerwall battery but not from any other brands.

    How Much Does Sunpower Solar Cost?

    Sunpower Solar will typically cost between $15,000 and $40,000; the pricing for the system largely depends on where you are located, how much electricity your system needs to produce, and what type of solar panel you choose.

    One of the things that can help with the total costs of your Sunpower system is the type of solar panel you choose and the roof space you have. Sometimes conventional panels are a bit finicky about where they can be placed and how they will function. The great thing about Sunpower is that they can be installed in a smaller space than conventional panels, and they still have a strong performance warranty in place.

    Sunpower will help you with your incentive, loan, and savings options to help you keep the total costs of your solar energy system down. Still, they are certainly not the most inexpensive solar panel provider on the market.


    SunPower solar tries to offer fewer panels with the highest efficiency. From a product warranty standpoint, this is a positive. Sunpower offers their complete confidence warranty that ensures your solar panels are functioning for 25 years. The way to check on the functionality of these solar panels will be to use the mobile app with the monitoring system.

    If you notice that the solar battery starts to fail or there is a problem with producing the wattage you need, the company will see what they can do from a warranty standpoint. Keep in mind, as we were reading these Sunpower reviews, that there were very few complaints about the ability of the panels to produce electricity.

    One of the negatives of the renewable energy movement is that it is still a bit expensive for homeowners. Taking advantage of Sunpower’s warranty can help you feel more confident about the purchase you are making.

    Financing Plans &  Options

    When paying for a home solar system, you can either pay in full or finance the solar panel systems and the installation costs. There are three options with Sunpower when it comes to financing and affordability of their panels. Remember that aside from being solar panel manufacturer, SunPower also is an installation company.

    Full Purchase

    The full purchase typically allows you to pay for your entire solar panel purchase upfront, and then you will get the full benefits of the savings involved with moving to solar energy. The full purchase requires a large out of pocket investment, but it does help that the current Federal tax rebate is still in place, offering a 26% savings.


    The loan or financing option is the most popular option among most solar installers. With this plan, you will be able to put down a portion of the total cost of the solar system and then finance the rest. The great thing about this option is that you will likely have the extra money in your pocket due to lower energy costs, and the money can be used to pay down the loan.

    Solar Lease

    The solar lease is when you don’t own the solar panels, and they are actually owned by Sunpower. With the solar lease, you will pay Sunpower for your electricity which will be purchased at a much lower rate than you are currently paying. The only downside here is that you don’t own the panels.

    Specials or Incentives Offered

    Although there are no specific specials or incentives being offered at the moment, here are a few of the things that Sunpower advertises as being a reason to go with their panels when you make your decision.

    Zero Down

    If your credit score is good and you have a strong history of paying bills, you may qualify for a solar panel system with $0 down. In addition, Sunpower will work out a rate for you on a monthly loan within a range you can afford. This will all depend on availability in your area as well as your financial history.

    Payment Flexibility

    Having the solar lease option and several different solar panels to choose from will help you fine-tune this system to be something you can afford. Sustainability and moving off the grid are all important, but you must also be able to afford the lifestyle.

    Federal and Local Incentives

    Sunpower will help you with understand which credits and incentives are best for your home. The federal tax credit is known as the best overall option for homeowners as there is a 26% savings right now on the total amount of money that you will owe on your system. The 26% will come back to you as a tax rebate, but this program is set to end in 2024.

    In addition to the federal solar incentives, there are also local options for saving money. The fact that Sunpower is offered in 50 states can be very beneficial to those that are in solar-friendly states. If your area is known for making a push towards green energy, you can see additional state or local-level incentives.

    In-House or Contracted Installations

    Currently, Sunpower Solar has access to install solar panel systems in 50 states. When you contact Sunpower, they will give you a free quote and explain the way that their system works. The process will allow for the designing of your system, permitting, and finally, installation. Sunpower works with homeowners throughout the entire process and ensures that there are no issues between the sales cycle and the installation process.

    What Solar Panels Does Sunpower Solar Use?

    Sunpower Solar has now started producing its own solar panels. This is a positive for many homeowners that are worried about keeping the entire process with one company. Sunpower used Maxeon solar technology to make the much more efficient solar panels and offer better value for homeowners long term.

    One of the reasons that Sunpower is a bit more expensive than other manufacturers is that they choose a solar panel that is very high end and expect it to do all of the work for you.


    Sunpower Solar can manage most of its business and solar solutions without the help of other companies. As we mentioned, this is a very large company. However, they do partner with AAA. Some areas of the country will allow for an additional AAA discount that can help you earn a $1000 Visa rewards credit when you go with a full solar panel system from Sunpower.

    Service Area & Availability

    There are currently fifty states with Sunpower Solar locations. This is a tremendous advantage over other solar companies as most are only offered in about ten to twenty states. For those areas of the country that have had a hard time finding access to solar, Sunpower is a solution.

    Sunpower Solar Reviews From Actual Customers

    Reading reviews from actual customers will help you get a better feel for what Sunpower has to offer and whether or not it is a good company for you to invest in. The reviews from Sunpower solar are overwhelmingly positive, and that can certainly help with the fact that the pricing from the company is a little higher than others on the market. Here are a few of the more helpful reviews on the Sunpower solar system.

    “Installation was done in two days, and the crew was thorough throughout the installation. They would explain to me any questions I asked and left our yard cleaner than they found it. Communication was continual during the process, and everyone I spoke with were helpful. Looking forward to having our power supplied in a reliable manner.”

     Ron C.

    “I’ve been trying to connect my Solar Monitoring System to SunPower, and I was not successful after numerous attempts. Finally, I got hold of “Cath”” and Catherine M, and now all is well. Cath is very knowledgeable, helpful, and a joy to work with. She did not stop until the issue was resolved. An ultimate professional, and SunPower is very lucky to have Cath on their staff.”

     Manny F

    “Before I got this company, I did a lot of research from other companies and found Sunpower to be straightforward and professional. They gave a timeline of when to expect things. The installation was done in a couple of days. They left my house clean when done, and still they followed up to make sure things were working well. This company has been around for over 30 years and is very reputable. No regrets for making Sunpower my solar company.”
