Solar Rooftop Power Plant Commercial Scheme

For Commercial/Industrial use, Solar power system is one of renewable energy systems which uses PV modules to convert sunlight into electricity. The electricity generated can be stored or used directly, feedback into grid line or combined with one or more other electricity generators or more renewable energy source. Solar PV systems are a very reliable and clean source of electricity that can suit a wide range of applications.

Components Of Solar Rooftop System

Solar Panel
Solar panel is assembly of numbers of photovoltaic cell and it is used as a component of a rooftop system to generate and supply DC Electricity.
Solar Array
Multiple solar panel connected together and form a solar array.
Junction Box
An electrical junction box is container for electrical connections, usually intended to conceal them from sight and tempering.it also includes terminals for joining cables, its protection degree should be ip65.
Inverter (Grid connected Power Conditioning Unit)
The power conditioning unit (PCU) used in grid connected SPV system consists of an inverter and other electronics for MPPT, synchronisation and remote monitoring.The inverter is the most complicated part of the PV system.It has to act as an interface between the PV array and the Grid, it needs to trip the frequency of voltage or current goes outside acceptable ranges.
Net Metering Systems
In case of rooftop solar PV systems, the metering system is of net metering and focus would be on consumption.within the rooftop owners installations(with the grid acting as an energy Bank), in such case existing utility metre is to be replaced bi-directional (or import - Export Metre).

Features

  • PV System Scheme Of GoG & MNRE
  • Allowed solar capacity: Residential consumer up to 100% trust & social sector-up to 50% commercial MSME up to 100%
  • Meter: Bi-directional Metre and solar generation Meter
  • Surplus generation to be paid by DISCOM at APPC (Average Poll Purchase cost of the year of installation of system).
  • Banking of Energy: for one billing cycle
  • Wheeling/Transmission charges: No charges
  • Renewable purchase obligation (RPO): credited to DISCOM

Informations

  • A 1 kw photovoltaic system would generate an average of 3-4 units (kWh) per day,320 days are considered sunny days in Gujarat/other states and hence 1 kW photovoltaic system would generate around 960-1500 units of electricity per year. (*solar module cleaning twice a week regularly & 365 days availability of electricity).
  • Ministry of New and Renewable energy provide subsidy (CFA)
  • State government provides subsidies.
  • Connectivity charges of DISCOM and DISCOM agreement, Net meter charge as actual paid by customer.
  • If the required structure is more than 1 feet high then the customer pays extra structure cost.
  • Company gives 5 metres cable AC side and DC cable 50 metres only if they need more than cable customers pay extra cable Charge.

Electricity Generation By Solar Rooftop System:

A 3.2 kW photovoltaic system would require about 320 sq.feet of shadow free route of area.Large photovoltaic system would require proportionally more space to absorb more sunlight. Hence for example, a 5 KW system would require 500 sq.feet area.
