Solar Panel Technical SpecificationMaximum Power (Pmax): 50WMaximum Power Voltage (VMP): 18.56VMaximum Power Current (IMP): 2.70AOpen Circuit Voltage (VOC): 22.27VShort Circuit Current (ISC): 2.91AWeight: 2.6 KGSize: 660 x 395 x 25mmCell Quantity 32Power Tolerance: +/-3%Maximum System Voltage: DC1000VIn the event that the solar panel is in shade for a prolonged period, our solar panels either have one or two built-in bypass diodes which will enable the panel to continue generating.Half cut solar cells Solar Panels with half -cut solar cells and 9 to 12 buzz bars connecting the cells are 8-10% Smaller than typical square cell panelsSolar Panels with half -cut solar cells and 9 to 12 buzz bars connecting the cells are 3% higher effiiency than typical square cell panelsFull silicon solar cells used to be square, sometimes with the corners cut off, but now the mainstream trend with all the big solar manufacturers is for half cut, small rectangular silicone cells, due to their higher efficiency.Solar panel technology has moved on considerably in the last few years with the introduction of half cut solar cells which can provide 2 to 3% more efficiency and higher watts per square metre. This means that the same power solar panels used in the past can now be 8-10% smaller. Alternatively you can have bigger solar panels with higher power output, but don’t take up as much space.This works by doubling the number of solar cells and increasing the number of ribbons, (BB’s / buzz bars) which connect the silicon solar cells together within the panel. This helps to lower resistance in the panel, which in turn reduces tiny voltage drops in the many panel connections. Overall this provides more power output. The smaller cells are also less likely to have microfracture issues and with improved cloudy day performance.
