PolyCrystalline or MultiCrystalline solar panels are solar panels that consist of several crystals of silicon in a single PV cell. Several fragments of silicon are melted together to form the wafers of polycrystalline solar panels. These solar panels are made of multiple photovoltaic cells. Each cell contains silicon crystals which makes it function as a semiconductor device.
Solar panels are the major component of a solar power system. Every solar panel is capable of absorbing energy from the sun and turning it into electricity that can be used to power lights and small appliances. The performance of a solar panel is measured in Watts peak (Wp). Maximum power (Wp), open-circuit voltage (Voc), short-circuit current (Isc), and maximum panel efficiency describe the performance of a solar panel. These factors determine the electrical characteristics of a solar panel. When all factors are optimal, the quality of a solar panel also tends to be higher.
Polycrystalline solar panels are also called multi-crystalline and are made of a semiconductor block of silicon crystal that is cut into wafers. The wafers are then made into photovoltaic cells with an anti-reflective coating to help the silicon absorb sunlight during sunlight hours. This type of panel produces DC voltage from sunlight so the system needs an invertor to turn it into AC voltage.
Polycrystalline Solar panels are often preferred over Monocrystalline solar panels for their smaller size and flexibility. Also, because these solar panels are made up of several silicon fragments, there is more silicon in each panel, which means that polycrystalline solar panels absorb more sunlight than monocrystalline solar panels.
Polycrystalline solar panels, also recognized as multi-crystalline silicon or multicrystalline silicon, are made from a raw material that is melted in a process called casting. These cells are formed through an extrusion process and subsequently cut into wafers. This type of solar panels are more popular due to it's less cost compare to other advance solar panels.
Silicon is the most commonly used material in solar technology. Polycrystalline solar panels are less efficient than monocrystalline panels, but they cost less to produce. Their performance is inferior to that of monocrystalline panels because most of the silicon content remains unused, but they are durable and widely used. Polycrystalline solar panels are popular due to their low cost and easy manufacturing process.
The crystalline silicon solar panels are the excellent choice for a wide variety of purposes: from large power plants to smaller applications. These high-efficiency solar panels can be used for commercial, industrial, residential and utility-scale solar power plants. This is the perfect alternative to on grid solar system,off grid solar system and some unique functions which cannot be achieved by other solar systems.
