Polycrystalline solar panels

Polycrystalline solar panels or multi-crystalline panels are one of the most popular module types for Australian rooftop installations. Along with monocrystalline panels, polycrystalline modules are the best at generating solar power.

Polycrystalline panels are bluer in appearance, and the crystal formation is visible. Although there are differences between polycrystalline and monocrystalline panels, little separates the two types of modules in performance. You may be drawn to polycrystalline panels because they are a little cheaper, the downside will take up a little more of your roof space.

Advantages of polycrystalline panels

Polycrystalline panels are a high performance module that have several advantages over other types of panels:

  • Less expensive than monocrystalline panels
  • More efficient manufacturing process
  • Very popular
  • Durable
  • Benefit from large R&D investment

List of available poly solar panels

The list below highlights some of the best polycrystalline panels available in Australia:

REC polycrystalline panels

REC supplies their Twin Peak 2 polycrystalline panel to Australia.

  • REC TwinPeak 2 polycrystalline panel

As you would expect, the panel is not as efficient as their monocrystalline module of the same name, but at 18% is one of the higher rated polycrystalline panels.

Q Cells polycrystalline panels

Korean brand Q Cells supplies their Q Power G5 polycrystalline panel to the Australian market.

  • Q.Power G5 260w panel

The panel boasts an efficiency of up to 17.4%.

Jinko Eagle polycrystalline panels

Jinko supplies several polycrystalline panels to the Australian market. Their Eagle modules come in a range of wattages from 225w up to 335w.

  • Jinko Eagle 72 335w panel
  • Jinko Eagle 60 280w panel
  • Jinko Eagle 48 225w panel

Jinko panels are manufactured in China and are an affordable option if you are considering polycrystalline panels.

Polycrystalline solar panel prices

While monocrystalline panels produce more power per square metre, polycrystalline panels are not as expensive. If we break down the price of panels to the $ / watt (dollar cost per watt), polycrystalline panels are still cheaper than monocrystalline modules.

  • Poly panels are typically 12 – 20% less expensive

A slightly cheaper alternative

When you get quotes for solar installation, you will not just receive an estimate of the panels. The solar panel cost includes the inverter and the cost to install the system. When you get your cost, savings and payback figures from our calculator, you may be able to shave a little off the average price by selecting polycrystalline panels, though the only accurate way to tell is to organise detailed quotes from solar companies and inquire about their polycrystalline panels.

How they are made

Polycrystalline solar panels are made from silicon. The silicon is melted down and poured into a mould before being cut into thin wafers. The manufacturing process is more efficient than that used for monocrystalline panels, though there is less pure silicon content.
