To make things easier
We have organized the solar electric panels that we offer into, by Manufacturer and Solar Panel Watts, Please click manufacturer or Watts filter buttons to the left to choose from our extensive, hand-picked selection of larger solar panels ranging in size from 250 watt to well over 500 watt output.
We also carry a great variety of small solar panels ranging from 5-watt output to 195-watt. Solar Biz is here to help you! We offer a large variety of the world’s top manufacturers of solar panel mounting equipment.
The solar panel mounting, and installation equipment is in its own category. Please use our website as an up to date catalog and learning center!

What’s the difference between 60 /120 Split Cell and 72/144 Split Cell Solar Modules?
72-cell or 144-split-cell solar panels (modules) are generally the same width as 60-cell or 120-split-cell solar panels allowing the same number of rails for racking, but they feature 2 extra rows of solar cells which add to the length of the module.
The extra two rows lower overall module production cost per watt, therefore 72-cell solar panels tend to cost less per watt and will reduce installation time by requiring fewer modules than 60-cell modules.
Solar modules are generally around ½ Volt per cell, so a 72-cell solar module will typically be 6 volts or so higher in voltage, and weigh 6 to 10 Lbs. more than a 60 cell module.
Both 60 and 72 cell modules are available with monocrystalline and polycrystalline technologies. Monocrystalline PV arrays are somewhat more desirable in cooler less sunny environments by those requiring as much power harvest possible given a limited area.
In hot sunny areas, (Arizona and New Mexico come to mind) mono modules suffer, because they’re black and extra heat causes less efficiency and output. Current polycrystalline technologies are also quite efficient, approaching efficiencies of monocrystalline, at a somewhat lower price per watt on average.
