Monocrystalline solar panels are made from a single circular silicon crystal, cut into slices, commonly referred to as silicon wafers. These silicon wafers are then trimmed to squares to maximise space. These wafers are not trimmed to a perfect square, but with rounded edges to reduce wastage while allowing more wafers to be assembled close together for space efficiency. This gives the monocrystalline solar panels their signature rounded edges and uniform dark blue, almost black colour.
Due to the manufacturing process, monocrystalline solar panels are more expensive. The process is energy-intensive and uses pure silicon crystal, which is costly. However, the efficiency of monocrystalline is higher than any other materials commercially available. You can generate the maximum amount of solar energy by deploying monocrystalline panels.
Polycrystalline solar panels are made from silicon fragments, melted and poured into a mould, which gives its unique blue-speckled look. The silicon fragments can also come from the trimmings of the monocrystalline silicon wafers. This resulted in less wastage and a more straightforward manufacturing process, making it more affordable.
This also contributed to the popularity of polycrystalline panels, making up almost 50% market share. The combination of affordability and efficiency offers excellent value to many homeowners and businesses looking to deploy solar PV systems without breaking the bank.
The key characteristics of thin film solar panels are their thinness compared to monocrystalline or polycrystalline. They are made by depositing thin layers of photovoltaic materials, barely 0.3 to 2 micrometres, on a backing such as glass or plastic. This allows them to be lightweight and flexible. Thin film solar panels can be made using these materials:
Among the commercially available panels in Singapore, monocrystalline silicon panels are the most efficient in generating solar power.
The best panel for your use case depends heavily on the available space and the location. There’s no one size fits all solution; therefore, your solar contractor can advise you to find the best solar panels for your needs after a site visit. However, you can take these points as a rule of thumb:
