As the name implies, monocrystalline solar panels are made from a single crystal structure. They are the oldest of the technologies and the solar cells have a uniform flat color. Monocrystalline solar panels are a little more efficient and more expensive. You can install fewer high-efficiency mono panels, but the cost per watt is more expensive.

Making polycrystalline panels is cheaper and it’s a newer technology. The silicon cools unevenly and creates many different crystals giving it a less uniform appearance. Polycrystalline solar panels tend to be the most affordable, but they also put out a little less power. Even so, poly panels are gaining in efficiency and will usually have the lowest price per watt.

72 Cell Solar Panels

72-cell panels are commonly used for larger systems, especially utility-scale but also residential and commercial projects. Most 72-cell panels measure 77×40” with power output in the range of 325-400 watts. 72-cell panels are ideal for larger systems because the bigger size reduces the total number of connections and components, making for an easier installation with less maintenance.

60 Cell Solar Panels

60-cell solar panels tend to be the most common for residential and commercial systems. Most 60-cell panels measure around 66×40”, with power output ranging from 270-320+ watts.

36 Cell Solar Panels

36-Cell solar panels for for RVs, boats, and remote off-grid power systems. 12-volt panels are available in sizes from 5-160 watts. There are also small 24-volt panels available in a few sizes up to 190 watts. These solar panels have a nominal output of either 12 volts or 24 volts, which means they are designed for off-grid use and can’t be used in grid-tied PV systems. A few manufacturers offer flexible solar panels for RV, Marine and camping which are exceptionally lightweight and easy to install.
