Homeowners are increasingly opting for cleaner and more sustainable energy solutions in order to reduce energy costs and carbon emissions.

If statistics are to be believed, solar power has emerged as the most popular alternative energy source.

The demand for solar panels and related items is growing by the day, thanks to the growing number of property owners who are turning solar.

The good news is that customers can pick and select from a huge number of solar firms.

SunPower and Sunnova, two of the most well-known names in the solar sector, are compared in this post. Continue reading to learn more about these two well-known photovoltaic firms.

Organizational Profile

SunPower 

SunPower Corp is one of the most well-known names in the solar energy industry.

The company began as a solar research project in 1985 and has since grown into a full-fledged manufacturer of solar systems, photovoltaic cells, energy storage, and related items.

SunPower offers a number of service locations in the United States, but it also has customers all around the world.

Sunnova

Sunnova is a newcomer to the solar business, having started operations in late 2012.

Sunnova has developed in leaps and bounds to become a force in the industry, ranking up there with other respectable providers like SunPower and Q Cells, despite the fact that they have only been in business for a short time.

Customers in the United States and its territories benefit from the company's residential solar and energy storage solutions.

Customers that are ready to go solar can also get their roofs replaced.

Verdict:

Both solar suppliers are excellent in their own way, thus picking a winner based solely on the company profile is impossible.

Solar Panel Design and Type

There are three types of solar panels to consider: monocrystalline, polycrystalline, and thin-panel films, which come in a variety of types, shapes, and designs.

Monocrystalline solar panels are the most efficient in terms of energy output since they are constructed entirely of silicon, as opposed to other panels that are made up of a variety of components.

With that said, SunPower Corp's subsidiary, Maxeon Solar Technology, manufactures all three types of solar panels.

The Singapore-based firm is known for creating high-efficiency solar panels for both residential and commercial applications.

Sunnova specialises in monocrystalline solar panels for residential applications. This means that clients have fewer options when it comes to selecting their favourite solution.

Monocrystalline solar panels, on the other hand, are extremely efficient, making up for the lack of alternatives.

Verdict:

SunPower is the winner of this competition because they provide clients with more alternatives in terms of solar panel kinds and designs.

Rating for Efficiency and Output

The efficiency of a solar panel refers to the proportion of solar energy that it can convert into usable power, whereas the output rating merely refers to the amount of electricity produced when the solar system is operating at its best.

The majority of solar panels have an efficiency rating of 11 to 15%. Solar kind, insulation resistance, and temperature variations all contribute to this low percentage.

Solar panels from SunPower Corp have a maximum efficiency of 22.8 percent and an output rating of 360 to 500 watts.

Sunnova solar panels, on the other hand, offer a maximum efficiency of 19.6% and an output rating of up to 340 watts.

Verdict:

In comparison to Sunnova, SunPower Corp solar panels are more efficient and have a higher output rating.

Price Matrix

Solar installation can, without a doubt, be costly in the beginning. However, when you evaluate the advantages of solar energy, you'll see that your solar system will pay for itself over time.

When compared to other brands, SunPower Corp has the greatest upfront costs.

After all, no other brand of solar panels compares to SunPower (Maxeon) in terms of efficiency and performance.

The panels offer outstanding value for money, and SunPower provides consumers with a number of flexible lease, loan, and purchase options to offset the high pricing.

Sunnova solar panels are relatively inexpensive. Because the company concentrates on residential solar solutions and is still relatively new to the market, their solar systems are less expensive than SunPower solar panels.

For approved purchasers, the organisation also offers a $0 down payment financing option, but you must pay a monthly fee for the duration of the programme.

Conclusion: Sunnova solar panels are less expensive, while SunPower solar systems perform better.

When comparing the two firms, SunPower solar panels are the more cost-effective option.

Manufacturer's Service & Warranty

SunPower solar panels are covered by a 25-year warranty. It includes system repairs, defective part replacement, labour, and shipping at no extra charge.

Sunnova, however, offers a 25-year warranty that covers all system components and includes repairs and maintenance.

Sunnova concentrates on offering home solar solutions to customers in 32 US states and territories, whereas SunPower Corp has a global customer base through its sister firm.

Verdict:

In terms of warranty coverage, both businesses are tied. In any case, all of SunPower's and Sunnova's solar panels come with a 25-year servicing warranty.

Overall Goodness

SunPower solar products are just unrivalled in terms of quality. SunPower has been developing and perfecting its products since 1985 in order to provide the greatest solar panels available.

Sunnova solar panels are inferior to SunPower solar panels in terms of quality. Sunnova, on the other hand, is a little coy about which solar brand they employ for their home instals.

Verdict:

SunPower panels are considerably superior in terms of overall quality to Sunnova panels. SunPower has invested extensively in research to ensure that their solar products are long-lasting and of good quality.

Performance in the Real World

Real-world performance is a measurement of a solar system's ability to function under real-world settings.

In case you didn't know, temperature, shade, dirt or dust, and available sunshine all have an impact on the operation of a solar system.

The temperature coefficient has an impact on a solar panel's real-world performance; the smaller the coefficient, the better the performance.

SunPower solar panels have a temperature coefficient of -0.34%, whereas Sunnova residential solar systems have a temperature coefficient of -0.36%.

Verdict:

Sunpower panels perform better in real-world situations and can work effectively in harsh environments.

Feedback from Industry Experts and Reviews

Solar panel installation is a significant financial commitment. As a result, before installing one in your home, you should shop about, compare rates, and seek expert advice.

Comparing multiple customer reviews available online is a helpful technique to gauge a company's reputation.

Before making your final buying decision, you should also study opinions from industry professionals.

On solarreviews.com, SunPower has a 4.58 out of 5 rating, while Sunnova has a 2.55 out of 5 rating.

Furthermore, many clients appear to be dissatisfied with Sunnova's services.

In terms of service delivery, SunPower has a superior reputation among customers.

Customer Service

SunPower provides round-the-clock support from Monday to Saturday (6 a.m. to 7 p.m.) (7 am to 4 pm). You can contact the customer service representatives by email, phone, or live chat.

Sunnova's customer service representatives are calm and collected, yet the company has received numerous complaints about their support services, based on the ratings mentioned above.

Nonetheless, you may reach out to help via email, phone, or live chat from Monday to Friday (7 a.m. to midnight), Saturday (7 a.m. to 9 p.m.), and Sunday (7 a.m. to 9 p.m.) (Noon to Midnight).

Sunnova has longer working hours, which means they are always there to help consumers.

SunPower, on the other hand, has better customer service because to the numerous complaints about their services.

Yes. SunPower is a solar energy producing and storage company based in the United States.

It was established in 1985 and is headquartered in San Jose, California. SunPower solar panels, on the other hand, are not built in the United States.

The company's solar panels are manufactured by a subsidiary called Maxeon, which is situated in Singapore.

Some of the panels are manufactured in the Philippines and Malaysia, then assembled in France and Mexico.

Which solar firm has the best track record?

Panasonic, according to solarreviews.com.

SunPower is placed sixth with a score of 4.58, whereas Sunnova is not among the top ten most trustworthy corporations due to its bad rating.
