The manufacturing process involves cutting cylindrical silicon ingots into thin wafers, minimizing wasted material. Monocrystalline panels boast a distinctive black hue and high heat tolerance, making them efficient even in high-temperature environments. 

Their efficiency and longevity make them a preferred choice for residential and commercial installations.

2. Polycrystalline Solar Panels

Polycrystalline solar panels are recognizable by their characteristic blue-speckled appearance. They are made by melting multiple silicon fragments, resulting in a less uniform crystal structure than monocrystalline panels. 

Despite a slightly lower efficiency range of 13-16%, they are cost-effective due to the simpler manufacturing process. Polycrystalline panels are durable and perform well in various conditions, making them popular for residential and industrial applications.

3. Thin-Film Solar Panels

Thin-film solar panels are distinct for their thin and flexible design, allowing for versatile applications. They are manufactured by depositing thin layers of photovoltaic material onto a substrate such as glass, plastic, or metal. 

Three main subtypes of thin-film solar panel are:

i. Amorphous Silicon (a-Si)

Amorphous silicon panels have a disordered atomic structure, making them flexible and lightweight. While they have the lowest efficiency (around 7-9%), they perform better in low-light and high-temperature conditions, making them suitable for specific applications like calculators and watches.

ii. Cadmium Telluride (CdTe)

CdTe panels are cost-effective and efficient, with an efficiency range of approximately 9-11%. They are the most widely used type of thin-film panels. CdTe panels perform well in real-world conditions and have a faster energy payback time than other technologies.

iii. Copper Indium Gallium Selenide (CIGS)

CIGS panels offer a higher efficiency range of 10-13% and better performance in low-light conditions. They are flexible and lightweight, making them suitable for integration into building materials and portable applications.
