JinkoSolar is the latest manufacturer to unveil a 500W+ solar panel â€“ and it boasts significantly more capacity than others recently announced.
The Tiger Pro module series was unveiled through a virtual product launch last week. Four models will be available, with the Tiger Pro 78TR Monofacial offering 580 watts capacity, a conversion efficiency of 21.6% and a temperature coefficient of -0.35%/Â°C. Temperature coefficient refers to how much power is lost for everyÂ Â°C the panel is hotter than 25Â°C â€“ and -0.35%/Â°C is pretty good.
â€śWith various types of modules, Tiger Pro series enables the construction of more powerful and efficient solar power farms that will bring higher return on investment for projects with larger technical and efficiency requirements,â€ť saidÂ Kangping Chen, CEO of JinkoSolar.
Mass production of the Tiger Pro series is expected to commence in the third quarter of 2020. You can find out a bit more about the Tiger Pro here; but you may need to scroll down the page a bit â€“ on my system there was a large amount of white space at the top of the page.
Other manufacturers that have recently unveiled 500 watt solar panels include Risen Energy and Trina Solar (Tallmax, DuoMax and Vertex). Trina is already talking about manufacturing a 600W version of the Vertex by adding an extra column of cells.
In all cases, these panels have been designed for use in large commercial solar and utility scale PV installations. The panels are not only big on power, but also in size. A conventional 60-cell solar panel is around 1m x 1.65m and a conventional 72-cell module is approximately 1m x 2m. I wasnâ€™t able to find confirmed dimensions, but the new generation of 500W+ solar panels are even larger than this. While 72 cell panels can be installed on residential rooftops, extra care needs to be taken and these even bigger panels might be pushing things a bit.
However, some of the technology used in developing the modules may also be applied to panels for the residential market, so higher capacity solar panels for home use are certainly on the horizon. There are already smaller-format 400 watt panels available in Australia for residential use, manufactured by SunPower â€“ the Maxeon 3 (1.69m x 1.04m, weight: 19kg). It looks like Seraphim also has a 400W module available here, the Blade, but that is 2m x 1m and weighs in at 23kg.
