Seraphim Solar Panels- Independent Review

Seraphim banner image

Overview of Seraphim – Company History

Seraphim is a Chinese solar panel manufacturer, originally established in 2011. Established with a mission to develop a better world through continuous solar innovation, this is backed by 100+ members of their research and development team. This research has resulted in over 100 technical patents being lodged.

With manufacturing plants located in China, South Africa, and Vietnam, Seraphim has distributed modules to more than 40 countries worldwide. Seraphim has a 5 GW solar module production capacity, placing them as a mid-tier manufacturer in the global market.

Seraphim first entered the Australian market back in 2012. In mid 2020 Seraphim have increased their push into the Australian market agreeing to a 50 MW solar module supply agreement with the Australian based solar wholesaler and importer Raystech Group. The companies that import Seraphim Solar’s panels hold the responsibility for servicing warranty claims in the Australian market.

What is a Bloomberg Tier 1 Solar Panel?

Bloomberg’s infamous tier 1 ranking is NOT a measure of Solar Panel quality in any way. It is simply an indication of the bankability of the manufacturer based on publicly released information on the financial health of the company. This should give you an idea if the company is a large, well-known manufacturer.

What is PV Evolution Labs Top Performer?

PV Evolution Labs with support from DNV GL independently test solar panel reliability. The tests are voluntary, with solar panel manufacturers paying to participate in the testing. This testing process is internationally renowned and is an accurate reflection of the solar panel’s performance.

Seraphim was ranked as a top performer in the potential degradation test. This test simulates the panels loaded at maximum voltage whilst exposed to heat and humidity conditions. This is conducted to calculate how it will affect power losses.

Why is office location in Australia Important?

Most solar panel manufacturers entering the Australian market first set up their distribution channels and worry about customer service later. This has led to many unhappy customers who are left trying to contact Chinese head offices to claim on their product warranty. Seraphim’s global website names a sales center location in Melbourne but there is no ability to process warranty claims. Seraphim has outsourced the warranty claim function to SAE Group, who are a Solar Installer based in Tweed Heads New South Wales.

Relying on your solar installer is not always an option as we’ve seen many residential solar installers (including the large ones) go out of business well within the lifetime of the systems they are installing.

Seraphim currently have a shared office space on Collins St in Melbourne and an Australian phone number (03 9900 6423). They are still have not created an Australian website as most of the other Chinese solar panel manufacturers have done, so it seems they are keeping the Australian market with low overheads.

Model Range Available in Australia

The majority of Seraphim’s currently available solar panels are approved by the Clean Energy Council for the Small-scale Renewable Energy Scheme, which is Australia’s home solar rebate program.

S2 Series

Seraphim’s S2 Series features bificial and monofacial panels originally launched in 2019 and featuring the Seraphim ‘Blade’ panel. The panels used half cell technology as is now commonly adopted across the solar panel industry to improve yield and resilience to shading.

 

S3 Series

The later S3 Series also features monofacial and bificial panels with efficiencies up to 20.07% (SRP-375-BMB-HV). The S3 series also features a multi-busbar and slightly larger 166mm silicon wafers which help increase the total output of the panel.

 

SRP-BMB-DG Series

The SRP-BMB-DG Series features dual-glass technology meaning both the front and back sheet are made of glass. This reduces the likelihood of faults and degradation and results with a slightly heavier result with the 120 Cell panels weighing 22.5 kilos. The increased durability of the panels enables Seraphim to offer a 15 year product warranty and a 30 year performance warranty (compared to 10 years product and 25 years performance for the s2 and s3 series). This series reaches as maximum efficiency of 19.89 for SRP-410-BMA-DG.

Seraphim Commercial Solar Project

An example of a Seraphim commercial project is the system that was installed for the lighting retailer Beacon in June of 2016. The system consisted of 384 SRP-260-6PB modules, totaling a system capacity of 100kW. The system installed in Melbourne took the team of 9 technicians 2 weeks to fully install and connect to the grid. With estimated electricity production of 130 thousand kW/h annually, it will significantly reduce Beacon’s energy consumption costs. The project also included the installation of a Tesla electric car charger. The innovative drive of Seraphim was on display, as illustrated through the installed panel array for Beacon.
