The environmental benefits of solar energy have become more apparent in recent years.
One of the major disadvantages of polycrystalline cells is the inherent inefficiency. This is caused by the electrons not holding onto the energy long enough. If the electrons are not able to hold onto the energy for a sufficient length of time, it will be lost as heat.
Besides its efficiency, monocrystalline panels also have the advantage of having a sleek, black look. While a polycrystalline panel is often blue marbled, monocrystalline panels are a more uniform color. Similarly, the gap between the cells is smaller. Thus, there is more room for an electric field when the sun shines.
