Mono-Crystalline
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 17% and 20% versus 15% for the 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 (one of the largest Tier 1 manufacturers in the world with vertically integrated production line) we also provide to our customers the latest technology with 25 year warranty on performance.
- Monocrystalline are 2% more efficiency compared to polycrystalline
- Monocrystalline panel in standard 60-cell framce produces 310W and poly-crystalline 285W
- For 5kW system we need only 16 monocrystalline panels 310W but 17 polycrytalline panels, so more space is required.
- Monocrystlaline panel handle the heat better, that means it the loose less power as the ambient temperature raises.
With temperature coefficient 0.04%/K, if it is 20 oC hotter on the roof compared to standard test condition, mono- panels will loose only 0.06 Ams out of rated 8Amps. The poly-sillicon 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.
