Are Monocrystalline Panels the Best Choice?

Monocrystalline cells have a distinctive deep black colour and they are more efficient compared to the polycrystalline panels. A quality mono panel has a typical efficiency between 20% and 22% versus 15% for polycrystalline solar cells. Monocrystalline panels have also better aesthetics and sleek design. The cells are cut from a cylindrical silicon ingot.

As an exclusive distributor of Eging PV, Renesola and ET-Solar (All recognized as Tier 1 manufacturers in the world with vertically integrated production lines) we also provide to our customers with the latest technology with a 25-year warranty on performance. 

  • Monocrystalline are 2% more efficient compared to polycrystalline
  • The monocrystalline panel in a standard 108-cell frame produces 400W
  • For a 5kW system, we need only 10-12 monocrystalline panels 420Watt
  • Monocrystalline panels handle the heat better, which means they lose less power as the ambient temperature rises.

With a temperature coefficient of 0.04%/K, if it is 20oC hotter on the roof compared to standard test conditions, mono-panels will lose only 0.06 Ams out of rated 8Amps. The poly-silicon cells will loos 0.051%/K that is 0.08Amps. The loss is negligible between the two technologies. 

Finally, the monocrystalline panels behave better in less than perfect lighting conditions. Using micro-inverter and Tigo optimisers you can eliminate shadowing effect and increase the performance of your solar panels.
