Solar energy is harness through Solar Photovoltaic (PV) technology which turns sunlight ( radiation) into electricity through the use of semiconductors. When sunlight hits the semiconductor inside an PV cells. The electrons become released and bus bars absorb the moving electrons, which result in electrical current. When we put Solar panels that are connected in a planned manner in the sun, they start producing voltage and current as Direct current (DC) however in the majority of the nations in the world, Best Solar Panel Company in Pakistan appliances and other equipment operate on Alternate current (AC) which is why we have to connect every panels with an inverter which transforms DC to AC for use at home.
1: Off-grid Solar Power System / Grid Interactive System
This kind of system is employ in situations where you wish to lower the cost of electricity. In this kind of system, you can save on the cost per unit multiplied by the units generated by power. When your home’s electric consumption is low. And the power is strong, the r system will transfer the extra energy to the grid or the electricity company. If your electricity consumption is high, and power is low. Your Solar system will absorb the surplus energy from the grid or electricity company and transfer it to your home.
2: Off-grid Solar Power System / Standalone System
This method is employ in the event that electricity or grid is not available or when a person requires backup power to protect against power outages. In some instances the user may want to produce himself green energy! (No govt. involvement is necessary in this instance) It is a battery-power system, which means that the energy produce by the panel’s cells is store into batteries that are link to this system . run some of the essential equipment or devices directly from this system during the moment of grid inaccessibility or no sunlight hours and also
3: Hybrid Solar Power System
The one that is this is the combination of an off-grid and on-grid systems. The consumption of electricity of your house is less than the energy produced by the Solar system, contact Best Solar Companies in Pakistan the excess energy is stored in batteries which are part of this system. If the consumes more electricity than the solar energy production the excess demand will met by batteries. If the consumption of electricity in the home is less than the energy produce by panels. And batteries that are fully charge.Then the extra energy generate will be deposite to the grid/electricity department.
The Science Behind Solar PV Cells
Solar PV panels consist of numerous small photovoltaic cell which means they turn sunlight into electrical energy. They are construct of semi-conductive materials, which is most of the time silicon, which is a material that conducts electricity, and maintain the imbalance of electricity require to produce electricity.
How Panels Work
When sunlight strikes the semiconductor of the solar PV cells (step 1 of our high-level overview) the energy of the sunlight which is in the form photon capture by the semiconductor, scattering electrons that then move free in the cell. .
