WHAT IS SOLAR ENERGY & HOW SOLAR PANELS WORK?

Hey! Are you bored with the technicalities behind the term “SOLAR ENERGY” & “SOLAR PANELS” Not an issue, if you are not a technical bird then this blog is for you, my friend..!! Are you searching for “What is solar energy?” and “How solar panels work?” Then, let me introduce you to it…!!

WHAT IS SOLAR ENERGY?

Do you know that the Sun is the most plentiful source of energy that we have? It’s about 4.6 billion years old with another 5 billion years of Hydrogen fuel to burn in its lifetime. Yes, you heard it right..!! 

Having such a plentiful source of energy is truly a renewable source that won’t run out a lifetime. Solar energy works by capturing the Sun’s energy and heat (sun rays), converting it into electricity.

This conversion takes place without releasing any harmful by-products or greenhouse effects. We can use this electricity for our home. Some residential uses of solar energy include lighting, water heating, charging, hot water, cooling, and many more, saving a lot of electricity bills.

Okay, clear about what is solar energy & saving electricity bills? Let’s move on to understand “How solar panels work?” or some might have a question that may seem “How solar rooftop energy works?” I hold the answer to your question..!! Let’s begin.

HOW SOLAR PANELS WORK?

There are a few steps to understand how solar panels work?

Step-1: Sun’s energy is collected.

Just as a human, you need the energy to work and so you collect energy into your body by consuming healthy foods. Similarly, solar panels firstly receive sunlight. 

The solar panel contains Photovoltaic cells/solar cells. Here, you might be wondering how a visible light turns into electricity? This conversion is done by Photovoltaic cell/solar cells. A photovoltaic cell is a specialized semiconductor diode that converts the visible light into direct current (DC).

Step-2: Transforming DC to usable electricity.

But wait..!! Can a DC power your electricity? No, it can’t so what the next amazing thing that converts solar energy to usable electricity is?

Converting Dc into usable electricity is done by Inverters. Inverters convert DC electricity that is generated by solar panels, into AC (Alternating current) efficiently.

That’s a great principle that powers your residence.

But what’s next? Let’s have a glimpse in the next step.

Step-3: Electricity flows through your home with a solar meter.

Electricity flows from inverter to your residence through a solar meter. With the installation of solar panels, a solar meter will also be installed.

This Solar meter ensures and grabs any unwanted issues, measures the production, accesses the produced power, and for sure controls your power production. But what if it’s not a sunny day? What if it’s a rainy day? How will the solar panel catch the sunlight & will render power to our home?

Indeed, we have the answer to this..!! Gaze next.

Step-4: The electrical grid connections to the home.

As we all know, solar panels can capture the sunlight, converts and powers it during day time. We use electricity for the whole day..!! So, you might be questioning “How our residence gets electricity at night?” or “What if it’s a cloudy or a rainy day?”

That’s what we call a grid connection. Solar meters are connected to the grid. When solar power is overproduced or when it is a sunny summer day, it’s pretty apparent that solar energy produces more power than you use. What to do then?

The unwanted solar energy is sent to the grid connection of whatever company you use. The grid connection helps us to use electricity even at night when we’re not producing electricity. Also, we can use the stored solar energy at other times when we’re in need.

Examining the most common issues that people hold about solar adoption, offering a solution to this is a game-changer nowadays. Solar meter and a grid connection help you fix your obstacles…!!

WHERE TO HARNESS SOLAR ENERGY? And WHAT are the TYPES OF SOLAR SYSTEMS?

Got an idea of what solar energy is and how solar panels work? Now, you might be wondering where to harness the solar system in my residence? Let I answer you..!!

There are millions of homes and commercial buildings that have rooftops and receive abundant sunlight every day. But, still, they are paying electricity bills, wasting their money and the space on their roof. 

Rooftops are ideal for harnessing a solar energy system for your home or a commercial building. Utilize the space & the sunlight at this moment.

Wait, do you think about the types of solar systems available? Let me introduce the types to you.

WHAT ARE THE TYPES OF SOLAR SYSTEM?

There are three types of solar systems: ON-GRID, OFF-GRID & HYBRID SYSTEM. Might be thinking how to decide which one to use? Let your eye run down and you’ll get your answer.

In an ON-GRID solar system, the access power generated by the solar panel is fed to the utility grid-connected to the panel which helps you to use the electricity at night or in any undesired circumstance and also helps you to divide the power amongst people in your area. However, these systems are cost-effective and do not require additional expense.

While in the OFF-GRID solar system, batteries are used to store the access power. These systems render power for critical load in rural and remote areas and the areas with frequent electricity cut-offs. However, these practices require functional pieces of machinery, which are not cost-effective at all.

Whereas, in HYBRID solar systems which is a combination of ON-GRID and ON-GRID solar system where off-grid owns a utility back up power and on-grid holds battery bank. But these systems are more costly and also limit the usage of devices depending on the capacity of hybrid inverters.

Because of the analyses and complexities of different solar systems, when it comes to installing a rooftop solar system, On-grid solar system is forever acknowledged to be the best one with high utility backup and cost-effectiveness.
