How does solar power work
For most of us who are considering to go solar want to gain as much information as they can to help them decide whether or not to make the switch. By understanding the process involved in solar energy production, you comprehend every aspect of it and realize its benefits to you and the environment alike. Read on to understand every step involved in solar solutions energy production.
The Primary Components of your solar solution system are:-
1-Solar panels, which are made of Photovoltaic cells
We use set out to shift to solar energy, this is the primary equipment that you would be investing in it. Solar solutions like solar batteries for storage of excess electricity are also available but since they are not yet extremely cost-efficient, not everyone invests in them.
Not only does the solar inverter help convert DC current to AC current, it also provides ground fault protection for the entire system. System stats such as the voltage of the current being produced, maximum power point tracking, AC and DC current voltages etc. Some people have rightly claimed the solar inverter to be the brain of the system.
All the current being received from the solar inverter needs to be connected to a bidirectional meter. This meter helps keep a track of how much current is withdrawn from the grid and how much current was sent by the solar system to the grid. You may now need to know why the current is being sent back to the main grid. This is because, during peak sunlight hours, your solar system produces a lot more energy than you require. Assuming that you have not installed a solar battery, the surplus energy is pumped by into the main electricity distribution grid. This exchange is recorded by the electric meter,
During days when you have an overcast or during nights, there is not enough electricity being generated by the solar system to meet your needs. You can then rely on the electricity from the grid and make use of the credits you earned when your solar solution system pumped excess power back into the grid.
In lay man’s language, When sunlight falls on solar panels, DC current is produced. To get into details you first need to know that every solar panel is made up of several Photovoltaic(PV) cells. These cells are made up of semiconductor material, more precisely crystalline silicone. These panels are coated with positive and negative layers so as to help create circuits that are helpful in the generation of electricity.
Hence, when the sun’s rays, composed of primarily photons, falls on solar panels, the electrons in the atoms of the semiconductor material are displaced from their orbits. The presence of positive and negative layers help complete the circuit and this helps create a Direct Current(DC).
But as we are aware, DC current is not used in our households and we have appliances compatible with only Alternating Current(AC). For this purpose, we have the Solar Inverters. All the DC current that has been generated is fed to the solar inverter. The output received by the inverter is then used by us to meet our energy needs.
This particular system of measuring and making use of electricity and credits interchangeably is called Net Metering. In this system, by making use of the bi-directional meter we can measure the amount of electricity you sent to the grid. This amount earns you credits. When you withdraw electricity from the grid, the meter also measures the amount that you have withdrawn. You can pay for the withdrawn amount of energy with the energy credits you have earned.
You can also invest in a solar battery and start storing all the surplus energy you produce. This can help you to reduce and possibly even end your dependency on the grid.
This is how a household energy system operates. The other aspects of solar energy, such as the consumption of solar electricity by appliances, remains the same as with traditional electricity.
