Half cell Solar Panel 340w | 5BB PERC | Monocrystalline | Dimension: 1708x1000x35mm
Prostar PMS340M-120 mono perc half cell solar module 340w 120 cells is increased efficiency of half cut solar cells produce higher power output compared to a traditional solar module. This in turn increased the overall efficiency of the entire solar power system – be it solar power packs, rooftop solar power plants and land based solar power plants.
Smaller cells experience reduced mechanical stresses, reaching a decreased opportunity for cracking. Prostar PMS340M-120 mono perc half cell solar module 340w 120 cells has higher output ratings and are more reliable than conventional solar panels.
Today new solar module generation technology has increased the module output of up to 15 watts per module, compared to standard solar modules. Boasting the efficiency of up to 19.99%.
Prostar PMS340M-120 mono perc half cell solar module 340w 120 cells consists of conventional 158.75×158.75mm monocrystalline silicon cells cut in half. So 60-cells standard PV module becomes 120-cells half-cell PV module. As a result, new half cells have shorter bus bar conductors. The shorter conductors mean less amperage, thus, lower resistance. Lower resistance reduces power loss to 6% and increase the output power from 5W to 8W per module. It means 16.5% lower risk of hot-spots due to lower temperature in partially shaded cells compared to standart full cell modules.
-1- 5 busbar cell design improves module efficiency and offers better aesthetic appearance for rooftop installations
-2- IP68 junction box for long-term weather endurance
-3- Limited power degradation of Eagle module caused by PID effect is guaranteed under strict testing condition (85℃/85%RH,96hours)for mass production
-4- Higher module conversion efficiency thanks to half-cut cell design
-5- LOW hot spot temperature risk
-6- Excellent space utilization performance, increasing power density effectively and reducing costs of solar panel
-7- Lower temperature coefficient, zero depth reflection increasing
-8- High salt mist and ammonia resistance certified by TÜV NORD
Solar cells are cut in half to reduce the cell-to-module losses during assembly. Power loss is generally proportional to the square of the current times resistance.
Splitting the cell into two halves the current (not the voltage) of the cell, so when you apply this change to the equation the losses are reduced by 75%. The overall panel efficiency increased by 1,5-3% and this results in a reduction in panel heat production.
Panels with half cut solar cells can have junction boxes that are split into three, as you can see in this picture of half cut panel. The middle box is for the middle bypass diode.
A split junction box leads to lesser metallization than a standard panel in comparison to poly or mono panels and creates lesser internal resistance which saves space.
