3. Introduction:-
A photovoltaic system, also PV system or solar power system, is a power
system designed to supply usable solar power by means of photovoltaics.
The energy that can be produced by a solar cell basically depends on the intrinsic
properties of the cells and the amount of solar radiation which falls on the panel.
The typical size of the solar array as well as AC inverter required for solar PV
applications depends on the type of loads connected.
The energy from the panel can also be stored by using battery storage for later use.
4. Types of Solar PV System:-
Grid Connected Solar PV System:
Most systems today are Grid tied, meaning no battery back up involved.
The typical system includes the panels on the roof, which generate Direct Current from the sun’s rays.
This D/C current is carried by a conduit to an inverter, which converts the D/C power to A/C for use in
homes and business.
From the inverter, the electricity flows into the service panel, with excess power flowing back to the
Grid.
Grid Tie System is the simplest and most cost effective way to connect PV modules to regular utility
power.
Grid-Connected systems can supply solar power to your home and use utility power as a backup
As long as there is enough electricity flowing in from your PV system, no electricity will flow in from
the utility company.
If your system is generating more power than you are using, the excess will flow back into the grid,
turning your meter backwards.
6. Stand Alone- Off Grid System:
Stand-alone PV systems are designed to operate independent of the electric utility
grid, and are generally designed and sized to supply certain DC and/or AC electrical
loads.
Common applications are direct power to DC loads, water pumping and
telecommunications.
With an inverter it can also power AC load.
For systems with no battery the energy is used immediately; only works when it's
sunny.
Compents are Modules, charge controller, batteries, and may or may not have an
inverter which converts DC power to A/c power
10. Comparison of Different Solar PV System:-
S.No Grid connected System Off Grid System
1. You still have to pay the basic utility
bill, just not for whatever power
you’ve produced.
No power bills.
2. Eliminates need for batteries and /or
generator
Batteries can only store power for a
few days and have a maximum
capacity.
3. Provides seasonal storage if a net
metering or Feed-in Tariff program is
available.
No seasonal storage
4. Maintenance free for a solar power
system
require regular maintenance
11. Advantage:-
PV panels provide clean – green energy. During electricity generation with PV panels
there is no harmful greenhouse gas emissions thus solar PV is environmentally
friendly.
Solar energy is energy supplied by nature – it is thus free and abundant!
Solar energy is especially appropriate for smart energy networks with distributed
power generation – DPG is indeed the next generation power network structure!
Photovoltaic panels, through photoelectric phenomenon, produce electricity in a
direct electricity generation way
Residential solar panels are easy to install on rooftops or on the ground without any
interference to residential lifestyle
13. Future Scope:-
It receives solar radiation almost throughout the year, which amounts to 3,000
hours of sunshine. This is equal to more than 5,000 trillion kWh. Almost, all
parts of India receive 4-7 kWh of solar radiation per sq metres.
The Jawaharlal Nehru National SolarMission (JNNSM) launched by the
Centre is targeting 20,000 MW of solarenergy power by 2022
Thar Desert has some of India’s best solar power projects, estimated to
generate 700 to 2,100 GW.
