Components of a photovoltaic system




Solar energy has become one of the most preferred choice of renewable energy source due to its various benefits including accessibility, fast deployment and scalability 

In this blog, let us understand what are the different parts or components of a solar panel system or photovoltaic system


Photovoltaic System:


The solar system installed at home is also known as PV system or photovoltaic systems which derives its name from photovoltaic  effect which is the generation of electricity by certain  materials when they are exposed to light. Besides the very much visible solar panels there are certain other important components that come together and work in harmony to maximize the benefit of solar power for your home.


The main parts of a solar panel system at home:



1.Solar Panels :


These are the most identifiable components associated with solar power. The solar panels look like a blue or black colored flat part which is normally rectangular in shape. The solar panels are an array of many solar cells joined together in series to offer high voltage output. All these cells convert the sunlight into electricity through the photovoltaic effect. These solar panels are usually covered with a thin layer of plastic or glass for protection.



2.Mounting Structure: 


To secure the solar panels on any surface a mounting structure is needed. These also help to position the panels towards the sunlight to optimize their efficiency. These racks on which solar panels are mounted are made of strong metals and provide stability to solar panels 



3.Inverter: 


The solar panels generate electricity in the form of DC current which is converted to AC current by the inverter as the household appliances run on AC current and not on DC current.


4.Solar battery:


Solar battery is an additional component of the solar system but it is an essential part which helps to store the excess electricity produced to be stored for later use. In a way it helps to get maximum benefits from solar power by offering a reliable source of power on the days when there is less sunlight like on cloudy or rainy days. The solar battery also provides uninterrupted power to homes in situations when electricity from the grid is not available.



4.Net Meter:


If the solar system is grid tied then a net meter is also installed. It measures the amount of electricity that the home takes up from the grid and feeds back to the grid. It allows for the calculation of the compensation received for the extra energy that is sent back to the grid.


Apart from these components, there are other important parts like monitoring systems. Wiring and accessories and breaker box. They help in various functions of the PV system like offering real time data of the energy provided,  carrying electricity supply to various parts of the home,etc.


Summary

Solar or PV system has many different parts that perform different functions to help your home get a steady power supply. The size and configuration of each of them varies according to the location.

Understanding Types of Solar PV Systems

Image
Solar panels harness the sunlight to generate electricity for various applications. The solar system or Photovoltaic System installed at residential or commercial settings, are made up of different components including inverters, batteries, mounting structures, and electrical connections. They can be of three types – grid-tied, grid-tied with battery back-up and off-grid system. In this blog let us understand the types of solar PV systems: What are Types of Solar PV Systems: 1. Grid-tied or On-grid system: Grid tied PV system means integrated with the grid. The conventional electricity infrastructure is called the grid. Out of the three modes this is the most affordable one. Here the electricity is derived from the grid as well as the PV system. The extra electricity generated is sent back to the grid and the rebates are awarded as per the incentives set by the government.  The advantages include power delivery from both the grid and PV system . On the days when days are cloudy an...

Understanding Battery Capacity: Decoding Ah, VAh and C-rating

  In the world of batteries, understanding capacity is essential for making informed decisions about the right battery for your specific needs. Emiko, a leading battery manufacturer in India , is dedicated to providing reliable and efficient battery solutions. In this blog post, we will unravel the mysteries of battery capacity such as: Ah (Ampere-hour), VAh (Volt-Ampere-hour) and C-rating, to help you make the best choices when it comes to selecting the ideal battery for your requirements. 1.Ampere-hour (Ah) - The Measure of Stored Energy: The unit Ah, shows how much energy a battery can store and supply over a certain time. It tracks the rate at which electric charge moves over time.  For example, a 100Ah battery can theoretically supply a current of 1 ampere for 100 hours or 2 amperes for 50 hours. Higher Ah ratings typically indicate longer battery runtime. 2.Volt-Ampere-hour (VAh) - The Total Energy Delivered: VAh is a unit of measurement used to describe battery capacit...
