What are the major types of solar PV modules?

There are three major types of solar PV modules. Mono-crystalline Poly-crystalline (also known as multi-crystalline) Thin-film Each solar PV module type has its own unique features. These PV modules also vary based on how they’re manufactured, their appearance, performance, costs each are best suited for. Mono-crystalline and Poly-crystalline solar PV modules Both mono-crystalline and poly-crystalline solar PV modules have cells made of silicon wafers. To build a mono-crystalline or poly-crystalline module, wafers are assembled into rows and columns covered with a glass sheet, and framed together. Poly-crystalline cells are square-shaped whereas mono-crystalline cells are square with missing corners. While both of these types of solar PV modules have cells made from silicon, mono-crystalline and poly-crystalline modules vary in the composition of the silicon itself. Mono-crystalline solar cells are cut from a single, pure crystal of silicon. Alternatively, poly-crystalline solar cells are composed of fragments of silicon crystals that are melted together in a mold before being cut into wafers. Mono-crystalline modules typically have the highest efficiencies and power capacity. Thin-film solar PV modules Unlike mono-crystalline and poly-crystalline solar PV modules, thin-film modules are made from a variety of materials. The most prevalent type of thin-film solar module is made from cadmium telluride (CdTe). To make this type of thin-film module, manufacturers place a layer of CdTe between transparent conducting layers that help capture sunlight. This type of thin-film technology also has a glass layer on the top for protection. Other materials used to manufacture a thin-film PV module are amorphous […]

Why should I install a Rooftop Solar System?

The solar rooftop system is a photovoltaic system that employs solar panels on the rooftops of the buildings which convert solar energy to electricity. The electricity which will be generated will cater to your internal energy requirements. By Installing a Rooftop Solar System you can: Reduce your electricity bill. Make effective use of the idle rooftop area. Contribute to sustainability and ensure the reduction of carbon footprint. Avail government subsidies and subsidized credit options Ensure maximum efficiency with minimal maintenance.   To install a rooftop solar system you may submit your interest form by contacting your local electricity distribution company or click the button “Install PV”. To learn more about the rooftop solar technology, click the button “Know more”.
