Mono solar panels are photovoltaic (PV) panels that use single-crystal silicon cells to convert sunlight into electricity. They are considered more efficient than polycrystalline solar panels, with higher power output per unit area, but they also tend to be more expensive. Monocrystalline solar panels also have a distinctive dark blue color and often have round cells. They are commonly used in residential and commercial solar systems.

The size of mono solar panels can vary depending on the manufacturer and model. Typically, they range in size from around 0.5 square meters to around 1.6 square meters. The size of the panel will affect its power output, with larger panels typically producing more. The standard size for a most residential solar panels is around 1.6 square meters. Commercial solar panels are usually larger, around 2 square meters and above.

It is important to note that the size of the solar panel is not the only factor that determines its power output; the efficiency of the solar cells and the quality of the manufacturing also play a role. And also the location, the angle of the roof, the shading, etc. All of these factors should be taken into account when determining the appropriate size for a solar panel system.
