Difference between On-Grid and Off-Grid Solar Power Systems

Solar Power Systems used in residential and commercial loads can be distinguished as On-Grid and Off-Grid Solar Power Systems.

Difference between On-Grid and Off-Grid Solar Power Systems

To understand the difference between On-Grid and Off-Grid Solar Power Systems we can refer to their respective definitions:

On-Grid Solar Power System

On-Grid Solar Power Systems as the name suggests are Grid Tied or On-Line Solar Power Systems where Solar Electrical Energy is used in conjunction with main electrical supply. Grid Tied Power Systems receive power from Solar Panels Setup and also regular electrical supply by companies.

There is a provision in this kind of Solar Power Plant to switch back and forth between Solar Supply and Regular Supply.

During the night time or when there is cloudy weather and Solar Panels aren’t generating enough electricity to serve electrical loads you can switch back to your regular supply.

Solar Panels produce DC electricity and hence they are connected to a inverter which converts DC to AC and serves residential or commercial load.

Net-metering services are becoming common now a day where users have to pay only for electrical usage that is done when Solar Panels are unable to deliver required power. If consumers generate more electrical power from Solar Panels than their regular load consumption then they can supply that extra power to Electrical Grid and they will be paid as per the tariff rates.

In an On-Grid Power System there is no option to save the electricity from Solar Panels.

Off-Grid Solar Power System

Off grid solar power system is same as on grid system but you can store electricity generated by Solar Panels in batteries here.

In an off grid solar power system Solar Panels are connected to Solar Charge Controllers which are connected to Solar Batteries to store Electricity.

Off-Grid Solar Power System may or may not be connected to electrical supply mains.

Solar Batteries are connected with electrical inverters to serve AC loads.

Technical Specification of Batteries, Inverters and Solar Panels depend upon the Electrical Load Consumption.

Conclusion: On-Grid Solar Power System is without any power saving device and serves electrical load On-line when Sun is bright and an Off-Grid Solar Power System can be used to serve the load online as well as save power in batteries for later use when sunlight would fade.

What is the importance of Solar Energy ?

Importance of Solar Energy

Importance of Solar Energy

Before understanding what is the importance of solar energy we must understand what solar energy is ?

What is Solar Energy ?

Solar energy is the energy coming from sun that falls to earth surface. These light rays are a source of energy that can be used to generate electrical power. If a person stands without a shed in a bright sunny day he can feel the thermal energy of the sun. Hence this energy must be stored somewhere so that it can be used for the process of power generation and that can be done with the help of solar cells .Solar energy is a pollution free source of energy that can be used to charge these solar cells and transform it to be used as electricity.

Solar energy is one of the most important element for existence of life on our planet. Humans, Animals & Plants; all are dependent on Solar Energy. We can now harness this energy to use it for various other purpose such as electricity generation and geysers.

Importance of Solar Energy ?

Solar Energy is also important for Photosynthesis to take place. It is one important source of Vitamin D as well.

Solar energy is important as it is a clean and pollution-free source of energy.

The power generated from solar energy id Versatile considering its applications.

It can be used in Watches , calculators , vehicles , residential electric loads , commercial electric loads and entire city’s power supply.

Solar Energy is readily available free of cost to everyone. We can install Solar Power Plants to convert this energy into electrical energy. Solar Power Plants have Solar Panels, Solar Charge Controllers, Solar Inverters, Solar Batteries and Thermal Reflectors etc. as key elements.

Why are Solar Panels useful for our society.

Solar Panels

Work on Either

Photovoltaic model


Solar-Thermal model.

Solar Panels are electrical devices that can convert Solar Energy or the Light falling from Sun into electrical energy. The fuel cost is zero, the cost of generation is mainly the operation cost. Sun light is available upto and average of 10 hours a day in many countries and hence solar energy can be a useful source to generate electricity and such a source that is free of cost and naturally available. One of the most important factors of using solar energy is that it is a pollution free energy source that is readily available to us, the cost of generation is also low as compared to some other sources.

With the use of Solar Energy the need of Nuclear power will be considerably less as the generation of electricity by means of Nuclear Power produces harmful wastes.

Sometimes Fuel is required from other countries and hence countries have to pay the suppliers huge amount of money in order to fulfill the fuel demands to generate electricity. Solar Energy is available to every country and hence there is no need to be dependent on other countries.

Working Block DIagram of Solar Cell Used in Solar Panels

How Solar Panels Work

Solar Panels are constructed from solar cells , when energy in form of Sun Light ( Photons ) falls on the surface of solar cells electricity is generated by Photovoltaic Effect. The majority of modules use wafer-based crystalline silicon cells or thin film cells based on cadmium telluride or silicon. The electricity thus generated is in DC and it is used to charge the batteries , the power from these charged batteries is taken out and can be fed into the DC power driven appliances based on the rated voltage, if the appliances run on Alternating Current ( AC ) Inverters Solar are used along with batteries to convert the DC into AC. The inverters of rated capacity are used to serve the loads.
MPPT charge controller and Hybrid Inverters are used to maintain the efficiency of Solar Panel Systems.

A complete system consists of A Solar Panel ( Array ) , Inverter , Batteries , Mounting Structure and Wires.

Working Block DIagram of Solar Cell Used in Solar Panels

For complete understanding of How Solar Panels Work you can refer to this working block Diagram of Solar Cell.

In this block diagram you can see a Glass Lens Place that is mounted on the top of solar cell and below that glass layer there are three more layers:

  • Layer with N-Type Silicon
  • The Depletion Layer
  • Layer with P-Type Silicon

The N-Type Silicon Layer consists of Negatively Charged Electrons. The P-Type Silicon Layer Consists of Positively Charged Holes.

The Depletion layer of this PN Structure stops Electrons. Electrons must jump from valence band to conduction band for current flow. They need energy to cross this depletion layer and that energy is supplied by the Power in Sun Lights. When sun light fall on the surface of this Solar Photo-Voltaic Cell the electron flow occurs and hence we get the necessary electricity in DC ( Direct Current Form ). The voltage produced by these cells is of magnitude .58 Volts Approximately.

Metallic Strips are mounted on the structure to complete the circuit and get electrical output.

You can connect these cells in arrays to form a bigger structure and get Voltage and Current as per power requirement. A Solar Panel is an array of similar cells explained above.

Many Solar Panels can be connected in Series or Parallel or a Combination of Series and Parallel to get Required Electrical Power.
