- Monocrystalline solar panels
- Polycrystalline solar panels
- Amorphous silicon solar panels (most known as thin-film solar panel.)
What are Monocrystalline solar panels?
Pros: Highest efficiency
Cons: Highest cost
Shape: Squares with the corners cut off
Material: Each solar cell contain a silicon wafer that is made of a single crystal of silicon.
Performance: It has the highest efficiency and power capacity among all types of solar panels due to it’s purity of silicon.
Monocrystalline panel efficiencies can range from 17% to 22%, it will have a higher power output rating than other solar panels.
What are Polycrystalline solar panels?
Pros: Lower cost
Cons: Lower efficiency
Color: Dark blue
Material: Each solar cell contains multiple silicon crystals.
Performance: Polycrystalline panel efficiency ratings will typically range from 15% to 17%, with the developing of new technology, its efficiency is closer to monocrystalline solar panel.
What is Amorphous silicon solar panels?
Pro: Lowest cost, Highest sensitivity of light.
Cons: Lowest efficiency
Color: Common colors are Grey, brown and black
Shape: Amorphous silicon thin-film cells are the oldest and most mature type of thin-film.
Material: They are made of noncrystalline silicon, unlike typical solar-cell wafers.
Performance: It efficiencies can range from 6%-7%. But it has the highest sensitivity of light among all three types of solar panels. So it has used in many indoor designs.
Amorphous silicon has been used as a photovoltaic solar cell material for devices which require very little power, such as pocket calculators, because their lower performance compared to conventional crystalline silicon (c-Si) solar cells is more than offset by their simplified and lower cost of deposition onto a substrate.
