Overview of Hanwha Q Cells – Company History
Q-CELLS was founded in Germany in 1999 and has been producing solar silicon cells since 2001 and eventually mannufacturing solar panels in 2010. The company originally listed on the Frankfurt Stock Exchange in 2005. In 2011, after a number of acquisitions and joint ventures, Q-CELLs posted significant losses and ultimatley filed for insolvency in 2012. Hanwha Group acquired the assets from the insolvent Q-CELLS and launched the brand Hanwha Q Cells late in 2012. Hanwha Group merged Hanwha Q Cells with another subsidiary, Hanwha SolarOne, in 2014 and the merged company was listed on the NASDAQ between 2014 and 2019 and is now a private subsidiary of the Hanwha Group.
Hanwha Q Cells only uses solar cells of its own production to control the quality and meet their high standards, which is different from other manufacturers. Although panels were originally produced in Germany, manufacturing facilities have shifted to Malaysia, China, and South Korea. In 2021, Q Cells shipped 12.4 GW of the total volume of production.
Q Cells has served the Australian market since 2009 with its head office based in North Sydney and warehouses around the country, providing products and warranty support. In 2022, Q Cells modules reached about 10.3% market share in the residential and commercial rooftop segment of Australia.

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.
Q Cells Solar Panels are in the Bloomberg Tier 1.

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.
Q Cells Solar Panels are currently ranked in the PV Evolution Labs Top Performers across 5 of the 6 annual tests.

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 10-year product warranty.
Relying on your solar installer is not always an option as since 2011 we’ve seen over 700 residential solar installers (including the large ones) go out of business well within the lifetime of the systems they are installing.
Q Cells currently has an office located in North Sydney, NSW.

Q Cells Solar Panels – Points of Difference
There are many solar panels out there, what makes Q Cells solar panels stand out?
Multiple Manufacturing Sites
Q Cells owns four manufacturing sites globally making their solar panels and batteries (South Korea, China, United States and Malaysia). As a result, there is less risk of country specific market dynamics affecting their prices – as was observed in 2021 with the Chinese Energy Crisis affecting 90% of the solar panel market. Partly due to this diversification away from Chinese manufacturing, Q Cells solar panels have a high market share in the US (estimated at 24.1% in 2022).
Long history company and trusted products
Q Cells was founded in 1999 in Germany and has steadily grown their presence in the market over the last 20 years. Having been awarded certifications through most independent testing authorities including PV Evolution Labs and Bloomberg Tier 1, their panels have been trusted by large investment firms on many large-scale solar farm projects.
Q Cells’s Warranty for Australian Customers
Q Cells was provided an industry-standard 12-year product warranty and 25-year performance warranty. But on the new series G9+ and G10+ panels, the product warranty has been upgraded to 25 years, which equals the industry leaders in the market.
For the Q.Maxx and Q.Maxx-G2 panels, the summary of warranty terms and conditions:
12 years limited product Warranty: ‘For material defects or processing defects, Hot-Spot Protect and Anti PID Technology.’
25 years limited linear performance warranty: ‘At least 98 % of the nominal power within the first year. Thereafter, the decrease of the power output will not exceed 0.54 % p. a. Minimal nominal rated power after 25 years at least 85 %.’
For the Q.PEAK DUO-G9+ and Q.PEAK DUO-G10+ panels, the summary of warranty terms and conditions:
25 years limited product Warranty: ‘For material defects or processing defects, Hot-Spot Protect and Anti PID Technology.’
25 years limited linear performance warranty: ‘At least 98 % of the nominal power within the first year. Thereafter, the decrease of the power output will not exceed 0.54 % p. a. Minimal nominal rated power after 25 years at least 85 %.’
Q Cells Solar Panel Technologies
All the panels they currently sell in Australia are salt mist corrosion-resistant and suitable for installation in any location.
Currently, Q Cells offers a variety of panels in Australia, the most popular panels are from premium Q.Peak and Q.Maxx monocrystalline range, which can provide the best efficiency especially for those homeowners with limited roof space.
Q.MAXX series
The Q.MAXX is Q Cells lower cost option which provides 120 half-cut cell solar panels up to 360W with a 12 year product warranty. This series uses the next generation Mono PERC half-cut solar cells with 12 busbars per cell, which increases the efficiency up to 20.1%. Additionally these black panels offer an aesthetically pleasing for homes with visible roof-space. The solar panels degrade at 0.54% after the first year which beats most of their peers (normally 0.7%) and it is guaranteed under their 25 year performance warranty.
Q.PEAK series
The latest Q.PEAK DUO is a step up in technical specifications from the Q.MAXX and also offers an industry leading 25 year performance warranty. They also utilise the Q Cells branded technology, Q.ANTUM DUO, which is aimed at increasing the power output of each cell through in-house developed innovations. Ultimately this technology delivers a high efficiency rating of up to 20.2% and a low degradation rate of 0.54% a year after the first year. For residentail use, the panel’s power range from 335W to 415W. For commercial use, the power is up to 580W.
Tested in Australian Conditions
Not only does Q Cells carry out rigorous testing in the lab, but also in the field. Q Cells is one of the only manufacturers to perform cyclone testing in Australia. Q Cells modules have been installed at The Desert Knowledge Australia Solar Centre (DKASC) since 2012, a facility for solar modules operating in the arid weather conditions of Alice Springs, and display the performance onto the internet for demonstration.
Q Cells Efficiency
Solar panel efficiency is the ability of cells to convert solar energy into electricity. The higher the panel’s efficiency, the more power output generated by the solar panel. So a higher panel efficiency will be one of the main features to rate the quality. The efficiency of Q Cells modules will be depending on different types for each country. The available product line in Australia has the efficiency vary from 17.1% to 20.1%. Most of the popular panels have the efficiency of around 19% upwards, which reach to the level of the front line in the industry.

Q Cells Solar Panels Pros and Cons
Pros
- Listed as a top performing solar panel by PV Evolution Labs
- Tier 1 Solar Company by Bloomberg New Energy
- Have an Australian Head-Office in Sydney
Cons
- If you are looking for a more price competitive solution, Q Cells will not be for you. High on the premium list

So, Should I Buy Q Cells Solar Panels?
The Q.PEAK series offers good value for solar buyers looking for a 25-year product warranty but don’t want to pay the premium for the top of the line solutions (like SunPower or LG). In our opinion at Solar Choice, Q Cells offer a good middle range between your standard tier 1 cost-effective brand and the expensive premium options.
Despite a chequered history, the Q Cells brand appears to be in financial stable territory with the backing of Bloomberg’s tier 1 rating, so there’s a good chance that you will be able to receive all the value of the 25-year product warranty, even if your solar installer closes up shop.
Example of a Q Cells Commercial Solar Project – Yalumba Winery, Barossa Valley
In 2016, 1.4 MWp Q Cells modules installed in the Yalumba Winery project, the largest commercial solar PV system installed at an Australian winery in South Australia, producing around 2000MWh output annually. It is expected to reduce the energy bill for the wine business by 20% each year.

Reviews from Australians who have installed Q-Cells Panels
Great performing, have been flawless so far (4+ years).
Appears OK
No issues to date.
Suspect there are better panels available
They look good and seem to be working fine
No comment - performing as expected
Panels were installed in September 2020, this latest installation was the addition of a battery and updated DC inverter.
Not really, they work.
These panels were highly recommended to us by Johna
N/A
Seem competitive in price, and quality.Also local access to distribution and good parts warranty.
No problems with the panels for the last 3.5 years. These appear to be working well in all conditions
We chose Duo type to minimise effects of shading. So far, after 2 years, they are still performing like new, which is better than expected. 350W x 16 panels = 5.6 kW nominal. We chose 350W as it is the same as the microinverter rating. As they don't all face the same direction (10 panels face east, 6 face north - if we had the space we would have faced them all north) peak power is 4.8 kW in summer, 3.0 kW in winter. Energy on a clear sunny day is 35 kWh summer, 17 kWh winter.
so far so good and the dark panel blends in well.
Great product. Works in low light conditions ,we are usually fully charged around 10am, 16 KW. Great warranty
Did some research and found these were one of the best brands in the market, they do perform well even in very cloudy conditions
So far very efficient.
So far they are working well. It is early days though
See above.
WORKING VERY WELL INSTALLED FEB 2021
What my son researched is what we got
whilst yet to have an account, it appears the panels are operating correctly and efficiently
Appears to be a quality product and installed requested
Too early to say
Working well.
panels have been working flawelessly for over 18 months
