The ML-G10 solar panels from Q Cells are well-known for their lightweight, high-quality build, and affordable price range. The ML-G10 modules are monocrystalline units with an impressive 21.4% efficiency, 400 W to 415 W output capacity, and anti-reflective glass technology. 

Q Cells, formerly known as Hanwha Q Cells, is a global solar panels manufacturer that began in Germany in 1999. In 2012, it was acquired by a chemical company in South Korea, the Hanwha Group. Since then, Q Cells has operated as a subsidiary of its parent company.

Its research and development site remains in Germany, but its current headquarters are in Seoul, South Korea.

There are four Q Cells manufacturing facilities worldwide in South Korea, the United States, China, and Malaysia. At the same time, the brand’s sales network has expanded to more than 40 countries globally across Asia, Europe, the Americas, and Australia.

Suppose your household’s electricity demands currently exceed your utility bills budget, or you simply feel compelled to switch from fossil fuels to sustainable energy. In that case, solar system installation can help you address both concerns.

Choosing the right solar panels for domestic or commercial use can be overwhelming, especially with the proliferation of new brands in the industry. To that end, this review will cover Q Cells’ ML-G10 series of solar panels; these modules are noted for their efficiency levels and practicality for Australian weather.

We will cover everything about the ML-G10, including its price, key features, specifications, efficiency ratings, and warranty coverage. By the end of this review, you’ll know exactly if these panels are suited to your needs.

With that in mind, let’s get into it!

What is the Q Cells ML-G10 Solar Panel?

The ML-G10 series is Q Cells’ most notable solar panels series after its infamous G9 range. These G10 solar panels feature an increased efficiency rate and are available in 400 W to 415 W sizes. Moreover, their new Z cell and high-density technology ensure these solar modules provide a high-efficiency value of 21.4%.

A vital aspect of the G10’s popularity is centred on its monocrystalline PERC half-cut cells. These cells are incorporated with multi-busbars (MBB), a technology crucial for increasing panel output.

Q Cells ML-G10 Solar Panel Range

The Q Cells ML-G10 comes in two power yield ranges.

The 405 model, as the name implies, produces 405 W of solar power under standard test conditions (STC). Even under normal operating conditions (NMOT), the power output drops to 303.9 W, which is still impressive.

The 415 model, on the other hand, exhibits a 415 W power at standard test conditions and 311.4 W at normal operating conditions. The efficiency of these models surpasses 20.6% and 21.1%, respectively.

Q Cells ML-G10 Solar Panel Technical Specifications

As noted previously, The G-10 range is cited for its impressive price-to-value proportion. This is due to the product’s excellent technical specifications, as outlined in the G-10 datasheet.

What is the Q Cells ML-G10 Solar Panel’s Power Output?

When the ML-G10 solar modules are tested under standard test conditions (STC), the 405 W model yields 405 W power, and the 415 W model produces 415 W power.

However, under normal operating conditions (NMOP), the yield decreases to 303.9 W for the 405 and 311.4 W for the 45 models.

What is the Q Cells ML-G10 Solar Panel’s Efficiency?

At STC, the efficiency of the 405 models is equal to or greater than 20.6%, while the 415 model crosses the 20% threshold and reaches an efficiency equivalent to or beyond 21.1%.

The Q.ANTUM Z cell technology with high-density solar panels is responsible for their high quality. The panel reduces energy loss and boosts its electricity yield by simply reducing the distance between its cells.

What is the Q Cells ML-G10 Solar Panel’s Temperature Coefficient? Will it Perform Well in Australian Weather?

The temperature coefficient of PMPP is -0.34% / K, and the Nominal Module Operating Temperature or NMOT is 43 degrees Celsius with a variation of three degrees. The modules’ certified high snow (5,400 Pa) and wind loads (4,000 Pa) showcase their suitability for the extreme Australian climate.

What is the Q Cells ML-G10 Solar Panels’ Country of Origin?

The Q Cells brand range was initially German-produced. But in 2012, South Korean company Hanwha Group acquired the brand and shifted its headquarters to Seoul. Now, the Q Cells ML-G10 solar panels and most of the company’s products are made in South Korea.

Will the Q Cells ML-G10 Solar Panel Look Good on My Home?

The ML-G10 solar panels are fit for residential use with a high-tech and durable aluminium alloy framework that looks stylish and is sturdy enough to withstand harsh environments.
