Polysilicon is right at the beginning of the Solar PV chain. It is the feedstock material for the production of solar cells. Polysilicon, as the name goes, consists of multiple small silicon crystals. It is technically industry-grade silicon. Such industry-grade…

The majority of PV cells produced today use crystalline silicon (c-Si) as it is a light absorbing semiconductor. A polycrystalline cell (also called multi-crystalline) is cut from a multifaceted silicon crystal. Polycrystalline solar panels are one of the most popular…

Output of a solar power plant depends on multiple aspects but mainly on the capacity of the solar panels and the amount of sunlight available at the location. A solar PV power plant generates between 3-5 kWh (units) per kW…

On-grid solar is the connection of the PV system to the main electricity supply such that excess energy generated by the system can be exported to the grid, and electricity can be drawn from the grid in times of a…

Consider a scenario where a farmer living in an isolated rural community needs access to electricity. But the community is miles away from grid access. It is in this situation that that the concept of off-grid gains prominence. The term…

Net metering is a metering mechanism in which the utility meters the amount of excess electricity (typically solar power produced on the consumer’s rooftop) that the consumer exports to the grid. Net Metering is measured with a bi-directional meter. Net…

Megawatt-hour, represented as MWh, is a unit of energy. A Megawatt-hour (MWh) is equal to thousand kilowatt-hours. 1 KWh is the one unit of electricity. So, 1 MWh is thousand units of electricity or a million watt-hours. A 1 MW…

Multi-junction solar cells are solar cells with multiple p–n junctions made of different semiconductor materials. Multi-junction cells with more than one p-n junction have much higher efficiency than single-junction cells, but are also much more expensive.

Solar panels are mounted on iron fixtures so that they can withstand wind and weight of panels. The panels are mounted to face south in Northern Hemisphere and north in the Southern Hemisphere for maximum power tracking. The tilt angle…

The majority of Photo Voltaic cells produced today use crystalline silicon (c-Si), a light absorbing semiconductor. Mono-crystalline technology uses thin wafers sliced from a single, pure crystal silicon ingot. Mono-crystalline solar panels have the highest efficiency rates since they are…
