SERAPHIM company history

seraphim company history

Seraphim is a Chinese solar panel manufacturer that was founded in 2011, in Changzhou China. The company boasts an impressive 5GW global production capacity and over 8GW solar module shipping to 40+ destinations.

One of their biggest accomplishments was passing the TUV SUD Thresher Test in 2013 – becoming the first PV manufacturer to do so. This rigorous test showed that their panels are high-quality and can last long. In 2017 and 2019, Seraphim’s solar panels were ranked top performers by PVEL/DNV GL.

As of 2020, this Chinese company has manufacturing plants in China and South Africa and plans to expand into Indonesia and Vietnam in the next few years.

Australian office?

The one flaw in an otherwise nearly perfect solar panel is that Seraphim doesn’t have an Australian office. The company’s website only mentions a sales center in Melbourne, which doesn’t offer warranty claims services.

Seraphim has instead outsourced all their warranty claim services in Australia to the solar installers, SAE Group, which is based in Tweed head, New South Wales.

Why an Australian office is important

Since most solar panel brands in Australia come from China and Europe, customers want to have security that these companies can deliver on their warranty offers. That’s why having an office in the country is crucial.

An Australian office makes it easier for homeowners to get help when things go wrong and reduces their reliance on unreliable suppliers.

After all, no one wants to spend hours on the phone with some Chinese customer support trying to explain their case.


Are SERAPHIM solar panels perfect for rooftop solar?

Yes! Seraphim solar panels are among the best solar panels in the Australian market. The panels are efficient, reliable in power output, and are aesthetically pleasing.

Their high module efficiency makes them suitable for small roofs as you will need only a few modules.

Seraphim panels are also very durable and can withstand heavy snow and wind loads (about 5400/2400 pascals). You’ll therefore incur very little in maintenance and repair costs.

Latest leap forwards for SERAPHIM solar panels

Seraphim Solar has rapidly expanded since 2011, providing reliable solar energy across the globe, Australia included.

This solar company has made several innovations that have put them in the limelight.

In 2016, they launched 18.23% high-efficiency Eclipse panels. They also launched their Dual-Glass module the same year. In 2017, the company launched the Blade module with up to 2% power yield gain (half-cell technology).

In subsequent years, Seraphim continued producing top-quality panels. In 2020, they unveiled their New S4 half-cell series that can achieve up to 540W power output and a maximum module efficiency of 21.1%.

Why SERAPHIM solar panels?

Seraphim Solar’s unique edge in the Australian market is its focus on PV technology development. With over 100 patents credited to the company, Seraphim has produced highly efficient and low-cost solar modules.

To prove their reliability, Seraphim offers more than the standard 10-year product warranty and a 25-year linear power on their solar panels. Some of their panels come with a 15-year product warranty and a 30-year performance warranty.

Another big difference between this warranty and other Tier 1 companies is that Seraphim allows you to get insurance for your panels through PowerGuard.

The insurance is tailored to cover you even if Seraphim goes out of business during the panel’s lifetime. This shows great confidence in the product.

For Australian homeowners, Seraphim has also made a deal with Australian Solar wholesaler and importer Raystech group to supply 50MW of their high-performance S3 series half-cut cell solar modules in the country.

This makes the cost of going solar very affordable.


Cell technology

Seraphim adopts the half-cut cell technology on both monocrystalline and polycrystalline cells to manufacture solar panels of the highest efficiency and performance. This technology lowers the current generated in the module, thereby decreasing power losses and the impact of shading.

They also include a 5-busbar design, which improves the solar panel’s surface current collection and results in higher power output.

Most newer models, like the S3 series panels, also incorporate the 166mm silicon wafer technology in their design – and the Bifacial series makes use of the bifacial technology.
