The answer to this question is – Yes and No.
Firstly, let us have a quick review of monocrystalline panels.
A monocrystalline silicon panel is made of monocrystalline silicon cells. These are made from monocrystalline silicon wafers, which in turn have been made from the molten polysilicon in such a way that the wafer and cell have a highly homogeneous crystal structure, and as a result, a higher efficiency at converting light to electricity.
Thus, the key benefit of having a monocrystalline solar panel is its higher efficiency, which essentially implies higher electricity generation for the same panel area when compared to a polysilicon solar panel.
Now. you might ask why you should not be using monocrystalline solar panels all the time as they can generate more electricity per unit area.
The answer has to do with – you guessed it right – cost.
Monocrsytalline solar panels cost a lot more then polycrystalline solar panels, so you might not want to use monocrystalline solar panels for all occasions and scenarios.
Yes, if you are seriously constrained for area, and getting the highest electricity output is of the highest priority for you – this is some times the case for select rooftop solar power plants.
If area is not a constraint, which is the case for a large number of ground mounted solar farms, you are better off using a high quality polycrystalline solar panel for best returns on your investment.
