Solar Photovoltaic (PV) Power is emerging as the major resource. The growth and use of this green and clean energy across the globe have increased tremendously. Due to the increasing demand for solar energy and power, remarkable advancement has been made in the research and development of solar PV Modules and technology. It is a reliable source of energy and hence, photovoltaic effect is given more importance.
Solar PV module price trends have changed a lot in the last few decades. To have a brighter and cleaner future, Solar PV module cost is steadily going down. Solar PV module price is now reasonable so as to fit in everyone’s budget. For encouraging the use of green energy and energy independence, solar PV module price is kept affordable.
Solar PV modules work on the photovoltaic effect. In this, a Photovoltaic cell converts the sun’s radiation into electricity. When sunlight shines on a PV cell, the light gets absorbed, reflected or passes through it. This absorbed sun’s radiation generates electricity.
Monocrystalline Silicon Solar PV: It is the most efficient module. The Monocrystalline silicon solar PV module is the best as this technology aims to deliver efficiency. It is measured by wattage output based on the size of the panel. However, this silicon solar PV module is costly. Other types of solar PV modules like polycrystalline silicon provide efficiency levels that are very close to these types of monocrystalline modules which are available at half the cost.
A monocrystalline solar module is one of the best solar PV modules and is made by growing an oval-shaped single crystal. These panels are cut into various unique and distinctive patterns. In this type of module, the crystal framework is even that makes a steady blue color without any grain marks. Thus, it becomes best in purity and offers highest efficiency levels.
Polycrystalline Silicon Solar PV: This module is made by casting method. Molten silicon is poured into a cast. The crystal structure in this type of module is imperfect and has boundaries where the crystal formation breaks. Because of its method of construction, this module has a grainy appearance.
Some impurities may be present in this type of crystal and hence, the polycrystalline silicon solar PV module is less efficient when compared to the best solar PV modules like monocrystalline ones. However, its manufacturing process uses fewer materials and energy and hence, this module becomes cost-effective.
Thin-Film Solar PV: These are portable and lightweight. Thin-film modules are best for certain projects which need less power but demand portability. These films are made from a plethora of materials. The popular options are amorphous silicon, copper indium gallium selenide and cadmium telluride. As this technology is still emerging, these types of modules are cheap.
For the majority of applications, a monocrystalline or polycrystalline solar PV model is generally the best option. These technologies are well- established and offer the right balance of price, quality, efficiency, and reliability.
