Polycrystalline solar cells are newer than Monocrystalline solar cells.

They are more affordable in price but are less efficient than monocrystalline solar panels.

Polycrystalline solar cells are easy to spot because they are blue. If you look at them closely, you’ll see that these cells have a mottled appearance with varying shades of blue.

While these PV panels are still fully functional in South Africa, they are slightly less productive in high heat and cloudy weather.

The Solar Panel - What you need to know

Because they are less efficient than monocrystalline panels, you may find that you will need to add a couple more panels to your array so that you’ll be able to produce enough solar power to cover your usage.

Currently, Canadian Solar Panels are the only brand of Polycrystalline panels that we stock. But all of our solar panel prices are market competitive.

Polycrystalline cells are created by fusing pieces of silicon crystals using extreme heat, then they are poured into a mould and then thinly cut once they have cooled.

Solar Panel Size

Not sure what size solar panel to get?

Solar Panels have grown in wattage rating substantially over the last few years. Back in 2018/2019, our most popular size was 280-300W. Now we’re looking at 450-550W solar panels being the most sought after.

Stock availability may be an issue in the long run if you decide to buy a smaller solar panel. We can no longer get stock of the 280-300W solar panels from our suppliers, so it’s essential to consider the future growth of your Solar Power Kit.

If your inverter has multiple MPPTs, you can also max out one MPPT and add more solar panels later.

Whatever your needs, we can help you find the best solar panels for your needs.
