LONGI LR4 72 HPH perc 450W solar panel

The LONGi LR4 72HPH 430W solar module featuring a anodized frame and TPT back sheet has been designed with improved technology. Thanks to the use of highly conductive wires, it now performance well in efficiency. Its powerful design will fit in your green home.

9bb (busbar) Busbars distribute electricity with greater ease and flexibility.  It is a thin strip of copper or aluminium between cells that conducts electricity which is called a busbar.  It separates solar cells and conducts the direct current the cells collected from solar photon to the solar inverter, which converts the direct current into the useable current.

HETECH full black color pv modules with 9bb perc mono solar cells, manufacture by perc half pv technology ,black solar panel , high efficiency solar panels 440w 445w 450w commonly used for solar power system and commercial solar plant, single solar panel power range 440w-450w based on 144 half cells.

Big Size PV modules, are rational designed, excellent in workmanship, and have a stable performance MBB solar panels,power range covers 600W,  are widely used in photovoltaic power stations.

HETECH black frame solar pv modules with 9bb perc mono solar cells, manufacture by perc half pv technology , high efficiency solar panels 360w 370w commonly used for solar power system and commercial solar plant, single solar panel power range 360w-370w based on 120 half cells.

We configured solar panels with high conversion rate for this system.Solar power generation only requires some level of daylight to extract the sun’s energy, meaning this solar power system can still harness solar power during our frequent overcast and rainy days.

The HETECHSOLAR 72 HET-400M72AH solar panel features 144 5-busbar  Mono PERC half-cells that are PID Free and shade tolerant. They are certified for high snow (5400Pa) and wind (2400Pa) loads and have an IP67 Rated Junction Box for longevity in outdoor environments. The panels features high-voltage 1500V capability with UL & IEC certification, you can run longer strings with lower balance of system costs and better LCOE. HETECHSOLAR 72 HET-400M72AH solar panels include a 10-year workmanship warranty and a 25-year linear power warranty.
