The Workings Of Solar Energy

We know that the heat from the sun is good for our bodies and plants. So, how is solar energy harnessed? One thing that comes to mind is solar panels. 

The solar panel has a layer of silicon cells, a glass casing covered by a special film, a metal frame, and wiring. Most factories that utilize solar energy combine an array of panels on the rooftop or large outdoor spaces.

Sun rays hit the solar panel cells (photovoltaic cells), and the PV absorbs this light during the day. Each PV has a thin semiconductor made from two silicon layers. Since one layer is negatively charged and the other is positively charged, they create an electric field.

As the light energy from the sun hits the photovoltaic solar cell, it charges the cells, thus loosening electrons from the atoms in the semiconductor. 

The electronic field sets the loose electrons into motion to create a direct electric current. However, direct current is not the electricity used in homes.

So, how is solar energy converted to alternating current (or AC)? You can use an inverter to convert DC electricity to alternating current electricity. With modern solar systems, you can configure one inverter to handle the entire system or use individual microinverters behind the solar panels. 

After converting solar energy from DC to AC electricity, the power can be distributed through your home electrical wiring to power your appliances. It works similarly to electricity generated through the grid by the local power companies. 

Furthermore, solar panels can work together with the traditional power company, which means that if the solar energy fails due to unfavorable weather, you can turn to the power grid.

You can also store excess energy using batteries, especially when you are not home. This stored energy can be used at night or during unfavorable weather conditions. 

What Are The Advantages Of Solar Energy

When you Google the strength of solar energy, you will find many resources that have discussed this subject.

This article adds to the previous voices that encourage a shift to solar energy for the future of our planet. 

1- Solar Energy Is a Renewable Source Of Energy

Unlike fossil fuels that are extracted in specific locations and can be depleted with time, solar energy is a renewable energy source. You can harness solar energy anywhere if the sun is shining. 

Since the sun is here to stay for as long as the earth exists, you can use solar energy without fear of depletion. The earth will not run out of the sun’s radiation! 

Some scientists estimate that the earth will continue to enjoy the sun’s heat for 5 billion years, which means solar energy is here to stay.

2- Solar Energy Reduces Electricity Bills

Recently, power bills have been rising, and households are filling the pain. The cost of living has continued to rise in the recent past.

And with the biting cold during winter and scorching heat in the summer, electricity bills for heating and cooling living spaces have skyrocketed. 

How can you lower your power bills? That is where solar energy comes in. supplementing your energy needs with electricity from solar systems will significantly reduce your energy bills. 

How much of your bills you can save depends on the size of the solar system and your heat usage. 

For instance, if your business shifts to commercial solar panels, you can cover a huge chunk of electricity bills. 

3- Diverse Applications

You can utilize energy from solar panels for various purposes. For example, you can use solar energy to generate electricity without a traditional power grid. And you can also use solar energy to distill water in areas with no clean water and power grid. 

Modern technology has made it easy to install solar panels, with some replacing traditional roofing materials.

Therefore, you can use your roofing budget and invest in solar panels so that each single on the roof is generating electricity.

4- Low Maintenance Costs

Solar panels do not require regular maintenance. You should only keep them clean by wiping dust ad debris off their surfaces a few times a year. 

However, if you are cautious about your safety when cleaning your solar systems, you can hire the services of a reputable and specialized cleaning company to do the job for you. 

Most manufacturers provide their customers with a 20–25-year warranty on solar panels, which means they are long-lasting.

Maintenance cost is also kept low because the system has no moving parts, which could have contributed to wear and tear. You will only need to change the inverter after 5-10 years. 

Changing the inverter is important because it continuously converts solar energy to electricity and heat. Besides the inverter, you will also pay attention to the cables to ensure maximum efficiency. 

5- Technology Development

The solar power industry is taking advantage of technology to expand. The industry will continue to improve with intensity with technological advancements.

Scientists are considering innovations in nanotechnology and quantum physics. And these innovations will enhance the effectiveness of solar panels. 

6- Lucrative Tax Incentives

Some governments offer tax holidays and rebates to individuals or companies that have installed solar systems in a bid to support the green initiative. For instance, New York State provides a $5,000 tax credit to homeowners who have installed solar panels (About 25% of any qualified solar energy system equipment costs, and it is limited to $5,000)

These incentives are easy for homeowners to register a return on investment from the initial solar power expenditure. 

Solar energy could be about 40% of the U.S electricity supply by 2035 and 45% by 2050 and employ about 1.5 million people in the process, according to a study issued by the DOE solar energy.

Additionally, solar systems have created jobs for many people. However, you should not wait to install a solar system in the future since these incentives often have expiry dates. 

7- Solar Energy Is Environmentally-Friendly

Many companies and households across the globe are fascinated by environmentally-friendly ways of consumption. Solar energy is an ideal way to go green and support the environment. 

Unlike fossil fuels that emit greenhouse gases into the atmosphere, solar energy does not spew dangerous gases to the environment since it uses the sun to generate electricity. You can minimize your carbon footprint by installing a solar system. 

How About The Disadvantages of Solar Energy?

Solar energy faces several problems that make it lag. What are some drawbacks of this sterling source of renewable energy?

8- Solar Energy Has High Initial Cost

Although the prices of solar systems have reduced tremendously over the last decade, installing them is still not cheap. The cost of these panels is considerably high because you will reduce your energy bill for the next 25+ years. 

While you will greatly save by installing solar panels, not everybody can afford the initial investment.

9- Getting Permission Might Be Time-Consuming

Before installing your solar system, you may be required to seek necessary permission from the local government offices. Getting government approvals can take a toll on the project. 

The bureaucracy of obtaining a permit can be discouraging and costly for some people unless you hire professionals to deal with government officials

10- It Depends On Weather Conditions

Solar energy relies on the sun’s rays to generate electricity, which means you may produce limited or no electricity on a cloudy or rainy day. If the cloud is dense throughout the day, your solar panels may produce less electricity to satisfy limited home usage.

You can overcome this problem by storing electricity in solar batteries, but they require huge space, which most people do not have

11 – Not All Roofs Are Suitable For Solar Panel Installation

Is your home suitable for solar panels? You need a space on the roof, good orientation, direct access to sunlight from the top, and adequate materials to install solar panels on the roof

For instance, you need a large south-facing roof with direct access to sun rays to maximize your solar energy harvesting.

However, if your roof is west-facing and surrounded by tall trees, you may not produce enough energy for your home or business. 

Does Solar Energy Cause Pollution?

Solar energy does not generate pollution or greenhouse gases. Using solar energy can positively and indirectly affect the environment. Solar power is energy from the sun converted into thermal or electrical energy. Even though solar energy is a little unpopular, it is the most abundant, cleanest, renewable energy source available.
