When it comes to the Monocrystalline cells, different qualities are available.
Good quality monocrystalline cells require less surface area to achieve output. In contrast, poor quality monocrystalline cells may require more surface area to achieve the same output, which in turn means the panel is heavier and less portable.
When you see a panel with numerous “pieces” of cell all connected together you can tell that impure or poor quality cells have been used, the worst bits of the original cell have been cut away leaving the somewhat useable remains to be strung together. Some of the cheapest examples of this even exhibit colour differences within the cell pieces or amongst the groups of cells.
In short, the better quality the cell, the higher the efficiency, the smaller it can be and the longer it will last.
SunPower® cells are the best in the Monocrystalline market today.
Compared to conventional Monocrystalline cells they are more efficient as they are able to capture more sunlight. This is due to the grid-line electrical contacts on the rear of the cell.
Having no grid lines means they can absorb the maximum amount of sun.
SunPower cells also incorporate a solid rear copper back which helps to reduce fractures, become more resistant to cracks which in turn helps in preventing performance loss.
With strong connectors, cracking from movement and temperature change can be prevented.
In addition, they are not affected by shading. This results in consistent power output compared to standard mono-crystalline cells which can lose output or in some cases stop working altogether if a panel is partially covered.
All this results in higher efficiency, which can deliver more power in a smaller and lighter package.
