We receive a lot of enquires about our Jinko PERC mono panel series - many of our customers are interested by the PERC technology and it's ability to perform well in low-light situations.
To give you a better understand of how these technologies work, I've shared an expert review from powerfromsunlight.com about the Jinko Solar JKM PERC mono series.
We will provide a breakdown of powerfromsunlight's blog on Jinko Panel review.
As a Tier one solar panel manufacturer, Jinko Solar produces all individual pieces of their PV module, including frames and solar PV cells.
2. Nominal Power and performance tolerance
Jinko Solar's JKM PERC mono series has a positive power tolerance of 0 ~ +3%. means that the solar panel will always have a static maximum rated power greater or equal to the specified value (e.g Max 324w - 315w).
3. Solar panel efficiency
Good efficiency range: 17 - 20%
4. Temperature Coeffienct, NOCT
The temperature coefficienct of Pmax for the JKM PERC mono series is -0.39%. The closer to zero, the better it is. This figure tells us how much power the panel loses for every degree Celcius that the panel is hotter than 25°C.
The panel will lose 0.39% of its maximum power for every degree above 25, which is considered very minimum loss.
It takes into account the temperature factor which affects the performance of the solar panel.
5. California Energy Commission (CEC), PTC
Certified by California Energy Commission and Photovoltaics for Utility Scale Application Test conditions.
6. Number of Solar Bypass diodes
The JMK PERC mono series is a 60-cell solar panel with three bypass diodes, every bypass diode is installed to have 20 Solar PV cells.
7. PV Junction Box
PV Junction with IP67 rating, protected from dust and will properly function after temporary immersion in water.
8 Solar panel frame
Frame thickness of the JKM PERC mono series are 35mm. its made of anodised aluminium, perfect for corrosion resistance. Certified with IEC61250, IEC61730 and UL1703.
9. Solar Panel Glass
The JKM PERC mono series are made from low iron anti-reflective (AR) Coated tempered glass. Most of the glasses contains iron impurities, which reduces the quantity of iron content, that improves the transmission of light.
Anti-reflective coating on glass surface increase the share of sun irradiance effectively used for generating power.
PERC MONO technology: The JKM PERC mono series consists of mon-crystalline PERC solar cells, which stands for 'passivated Emitter Rear Cell', The PERC cell increases solar cell efficiency and prevents loss.
10. Solar backsheet
TPT backsheet - one of the best solar backsheet material
11. Solar panel weight
12. Solar panel dimensions
1650 x 992 x 40 mm
13. Solar connector type
14. Mechanical Load Pressure
Certified with UL1703/IEC 61215 to withstand harsh environmental conditions.
UL1703: PV modules can meet a maximum positive pressure of 3600PA and negative pressure of 1600Pa
IEC 61215: Meet Positive pressure of 5400Pa and negative pressure of 2400Pa
15. Fire Performance Warranty
TUV certified fire-resistance rating for their ability to withstand fire exposure.
16. The Test certificates
IEC 61701: Salt Mist corrosion Resistance, can be utilised trouble-free near sea which high salt content in the air.
IEC 62716: Ammonia Corrosion, can be safely installed in wet atmospheres of high concentration of dissolved ammonia such as farmhouses.
IEC 60068-2-68: Dust and sand resistance, can be installed in desert regions and operate under sandstorms.
IEC 62804: PID Free certificate, passed Potential Induced Degradation (PID) resistance test which test and evaluate the durability of PV modules under high voltage stress.
17. Warranty Period
Energy production warranty: Jinko Solar's JKM PERC mono series has a maximum performance digression of 0.82% p.a over the course of 25 years.
Material and workmanship warranty of 10 year product warranty - industry standard.
