What is a Mono solar panel?
Monocrystalline solar panels contain cells that are cut from a single crystalline silicon
ingot. The composition of these cells is purer because each cell is made from a single piece of silicon. As a result, mono panels are slightly more efficient than poly panels.
Polycrystalline panels have lower efficiency rates typically in the 13-16%
range. Monocrystalline panels have higher efficiencies in the range of 15-20%.
Because of the lower efficiency rate they are not as space-efficient since they
produce less power per square foot.
Solar panels in series are optimal in unshaded conditions. If shade covers a
single panel of your series array, it will bring down the whole systems power output. Each panel in a series connection is critical. Solar panels in series are also best if you need a low-amperage system.
