PV (Photovoltaic), derives its name from the process of converting light (‘photo’) directly into electricity (‘voltaic’). A Solar PV system is a power station that generates electricity from sunlight. The major components of a Solar PV system are Solar panel, Inverters & Battery.

• Photovoltaic solar systems use cells, consisting of one or two layers of semi-conducting material, to convert solar radiation into electricity. The semi-conducting material is generally silicon, which is the second most abundant element on earth after oxygen.
• Light shines on the cell creating an electric field across the layers.
• This causes electrons to flow creating electricity.
• On its own each cell only creates a tiny bit of electricity, but connected together to form panels, which are linked together to form a system, they create useful amounts.
• Panels are mounted on a frame.
• An inverter converts the direct current (DC) to alternating current (AC – or mains equivalent) electricity which is suitable for running appliances.
• Grid connected systems can export electricity they don’t use to the grid, and import it from the grid when    there is not enough sunlight.
• The best use of solar energy is to consume it while it is being generated. If the requirement is to store this power and consume it in the non-sunny hours, then solar energy can be stored in batteries for later consumption.

It’s typically 4-5 acres of land for each MW. However, it depends upon various factors such as module technology, structure configuration, shape of land, terrain etc.

Open Access is a concept that enables industrial & commercial users with more than 1 MW connected load to buy power directly from the generator or from the open market. Customers can choose from a number of competitive power companies, rather than being forced to buy power from the local utility monopoly. It not only helps in ensuring regular electricity supply at competitive rates but also enhances the business of power markets. Open access helps consumers meet their Renewable Purchase Obligations (RPO) as well.

BESS is an electrical energy storage system which can provide power as and when required. When paired with PV Systems, it can offer various functionalities like DG Mitigation, Peak Shaving, thereby, increasing the potential savings of the clients. In addition to this, it enhances the flexibility of the client’s power supply, especially for critical facilities which commonly face grid outages.

Independent Power Producer

• Falling module prices and maturing technology
• Aggressive competition
• Economy of scale considering large capacity projects
• Increased focus of foreign investment in Indian solar industry
• Easy access to debt financing
• Supportive Govt policies & Incentives

Appx 5-6 Crs per MW. However, it depends upon various factors such as capacity, project configuration, site characteristics etc.

Solar power is much cheaper than the power from grid and diesel generators. Today average cost of power from solar is Rs. 4.5-5 per kWh (For commercial and Industrial segments) while the average cost of power from the grid is Rs. 7 per kWh and Rs 16 per kWh from a diesel generator. (A litre of diesel generates around 3-4 kWh).

Appx 40-50% of the total amount on yearly basis. Utility-scale is cheaper owing to economies of scale.

Following factors should be kept in mind:-

• Location and layout of the solar plant.
• Orientation and shade-free area.
• Quality of equipment
• Design of the solar plant.
• Maintenance of the plant.
