This article will review several elements to help you decide if the HiDM module system is suitable for your house. 

We’ll discuss where the HiDM is manufactured, its cost, efficiency, specifications, warranty, and much more.

So let’s examine the unique features of the Canadian Solar HiDM!

What is the Canadian Solar HiDM?

The HiDM solar panel is a Mono-PERC High-Density Shingle Module. Manufactured by Canadian Solar, the HiDM solar panels feature PERC technology and reach a power output of 420 W and a peak conversion efficiency of 20.4%. They come in two varieties: the standard HiDM module and the HiDM All-Black module. 

The PERC technology it is based on increases the cells’ ability to convert sunlight to energy by 30%. Mono-PERC solar panels are distinct from thin-film panels.

HiDM solar panels are manufactured in a Korean factory that uses shingled Mono-PERC solar cells. Due to this shingling, the 60 cells may be packed into a smaller space than if they were laid out with gaps between them. 

These solar panels are some of the finest on the market and produce slightly more watts per square metre than HiKu panels, making them appropriate for homes with small roofs.

The Canadian Solar HiDM module is visually pleasing and functional; the lack of gaps between the panels and the bus bar allows more sunshine to reach the cells.

The HiDM solar PV module produces more electricity per square metre than other panels. It’s also more dependable since busbar failure is less common.

With the HiDM solar panels, shading effects are also decreased.

The HiDM has a 15-year product warranty and a 25-year linear power output warranty.

You can also install a solar inverter with your HiDM PV module system.

Your photovoltaic system’s Direct Current (DC) is converted to Alternate Current (AC) by a solar converter, which subsequently powers your home in real-time.

What is the Canadian Solar HiDM’s Power Output?

A HiDM PV module’s electrical output can achieve 420 W.

The monocrystalline PERC solar cells are sliced into six smaller cells and laid out in a shingled pattern.

A conductive adhesive connects the HiDM cells, providing several redundant pathways for electrical flow.

What is the Canadian Solar HiDM’s Efficiency?

The solar panel efficiency of the HiDM can reach up to 20.4%.

The efficiency of solar panels measures their capacity to convert sunlight into usable energy.

For example, when the sun radiates on high-efficiency solar panels with a 20.4% rating, 20.4% of the sun’s energy is transformed into electrical power.

Suppose the same quantity of sunlight shines on two solar panels with different efficiency ratings for the same period. In that case, the more efficient panel produces more power than the less efficient panel. 

The longer a solar cell lasts, the better it performs in converting solar energy into electrical energy.

The energy production by each solar cell determines the efficiency of solar panels, which is impacted by the cells’ composition, electrical setup, and other factors.

What is the Canadian Solar HiDM’s Temperature Coefficient? Will it Perform Well in Australian Weather?

The HiDM has a low temperature coefficient (Pmax) of -0.37 % / °C.

It certainly has the capacity to handle Australian weather, but this depends on the temperature and climate conditions.  

In Australia, all solar panels are tested at 25 °C. Temperature affects solar panels differently depending on the manufacturer. As a result, all solar panel manufacturers must give the temperature coefficient value for their particular solar panel. 

Some manufacturers have designed solar panels specifically for Australian temperatures and hot conditions.

This allows them to run more effectively at hotter temperatures and with a lower total temperature coefficient.

Most solar panel coefficients per degree Celsius are between -0.20 and -0.50%. In layman’s words, the closer this figure is to zero, the less a change in temperature affects the solar panel. 

If the TC is -0.50%, it implies that for every degree over the ideal temperature for solar panels of 25 °C, the overall efficiency of the solar panel declines by 0.50%.

What is the Canadian Solar HiDM’s Country of Origin?

Canadian Solar was founded in Canada, but the HiDM modules are manufactured in Korea.

Will the Canadian Solar HiDM Look Good on My Home?

Yes, the HiDM will complement your home if you live in a smaller space. However, your roof type will affect its placement.

Strong, long-lasting roofing materials, such as composite or asphalt shingles, concrete tile, or standing seam metal are ideal for solar panels.

The HiDM solar panels have a shingled Mono-PERC solar design that incorporates more solar cells into a smaller space, making them ideal for enclosed spaces.

The HiDM solar panels work best with:

  • On-grid rooftops,
  • Small rooftops, 
  • Solar carports, solar power stations, and
  • Other grid-connected applications.
