What's the difference between a 60-cell and 72-cell solar panel?
Popular for commercial and ground-mounted installations, 72-cell solar panels tend
to cost less per watt and may reduce installation time by
requiring fewer modules than 60-cell modules. 72-cell solar panels appear similar to 60-cell solar
panels yet feature an extra 2 rows of solar cells added to the length of the module. This lowers
overall module production cost per watt, passing savings on to the end-user. A 72-cell solar
panel will typically have a higher voltage, weigh
more and of course have a longer length than their 60-cell
These solar panels are available with monocrystalline and
multicrystalline technologies. Monocrystalline solar PV arrays are desirable by
those requiring as much solar power harvest possible for a limited area. Modern
multicrystalline technologies are very efficient, approaching those of monocrystalline, at a lower
price per watt on average. 72-cell solar panel system arrays composed of
multicrystalline (also known as polycrystalline) solar panels may require more installation area
than an equivalent mono solar panel system.
