What Is Solar Energy?

Solar energy is produced by the nuclear fusion reactions occurring at the sun's core. Intense heat and pressure lead to proton collisions, resulting in the formation of helium through nuclear fusion. This process has a vast amount of energy in the form of electromagnetic radiation, which is delivered to Earth as photons.

Solar technologies catch this radiation and convert it into proper forms of energy, which led to the development of photovoltaic solar panels, which can play an essential role in transitioning away from fossil fuels and traditional power plants.

Solar does not create power at all times, but it does so when it is most needed, such as throughout the day and during hot sunny periods when electricity consumption is highest. Australia is one of the world's sunniest countries, making it ideal for putting the sun to work, especially during peak seasons.

When Was Solar Energy Discovered?

Humans first employed solar energy in the 7th century BC to light fires by reflecting the sun's beams onto shiny things. In the 3rd century BC, the Romans and Greeks used mirrors and light torches to harness solar power during religious events.

French physicist Edmond Becquerel discovered the photovoltaic phenomena in 1839 at 19 while experimenting with a cell composed of metal electrodes in a conducting fluid. He observed that the cell produced more power when exposed to light; it was a photovoltaic cell.

In 1954, Daryl Chapin, Calvin Fuller, and Gerald Pearson invented the silicon solar cell at Bell Labs, the first PV cell capable of converting the sun's energy into electricity to operate standard equipment. Today, solar energy powers satellites, which orbit the Earth.

What Are The Advantages of Solar Energy?

Solar energy is clean and renewable, and there are numerous reasons why you should use it instead of gasoline or diesel.

  • Easy to Obtain: Solar electricity is available everywhere. It turns energy into a usable type of electrical current open to all. The sun gives us more power than we could ever utilise, and no one can monopolise it. 
  • Save Money: Installing solar panels or a solar electric system has become more affordable in recent years, saving you money. Some people may still be intimidated by the upfront cost of solar energy. However, it is essential to note that installation is a one-time operation. Paying for conventional power is a regular, continuous, and costly commitment, especially when electric rates climb. 
  • Environmentally Friendly: A clean, renewable energy supply helps us transition from polluting and unsustainable sources. Solar electricity is a practical approach to lower your carbon impact. Solar electricity has no adverse effect on Mother Nature. Solar power emits no greenhouse gases and, other than requiring a source of clean water to run, consumes no other resources. 
  • Economic Growth: As more people choose solar, there will be a greater demand for solar panel installation services. This produces more jobs for skilled workers, keeping the economy going.
  • Energy Independence: Energy independence means not relying on the power grid. This strategy exposes you to price increases and makes you susceptible to outages. With no other method of powering your home, you may encounter several problems in the event of harsh weather or damage to power lines.

How Solar Energy Works?

Do you have any questions on "how solar energy works?" Sun panels produce solar energy. A solar panel generates electricity when sunshine particles, known as photons, knock electrons loose from atoms and start them in motion. Electricity is the movement of electrons, and solar panels are created to capture and transform it into usable electric current. This mechanism is known as the photovoltaic effect, and it is the fundamental chemical and physical process that drives the great majority of solar technology.

Solar Cells & Photovoltaic Effect

A photovoltaic (PV) or solar cell has three possible responses to light: reflection, absorption, and transmission. The PV cell comprises a semiconductor material with intermediate electrical conductivity between insulators and conductors such as metals. Photovoltaic cells can be constructed using a range of semiconductor materials.

The semiconductor absorbs light energy and transfers it to electrons in the substance. This surplus energy allows electrons to move as an electric current throughout the material. The electricity is collected via conductive metal contacts on the grid-like lines of solar cells and subsequently utilised to supply power to your home and the electric grid.

The efficiency of a photovoltaic (PV) cell is the ratio of electrical power generated by the cell to the energy received from incident light, reflecting the cell's ability to convert energy from one form to another. The amount of energy produced by PV cells is determined by the properties of the available light (such as intensity and wavelength) and the cell's many performance factors.

solar cells
  • Solar cells are powered by sunlight, which energises and moves electrons.
  • Electrons flow from the junction between cell layers, generating electrical current.
  • Metal plates and wires trap electrons, generating power.

Solar Panels Capture Solar Energy

First and foremost, you should understand how solar energy is produced. Solar panels transform solar energy from sunlight into electrical power for your home, as previously stated in terms of the photovoltaic effect. The more sunlight the solar panels receive, the more electricity they produce. 

During peak sun hours, your solar array's panels receive the highest concentration of sunshine, allowing them to convert sunlight and generate the most electricity. The three most popular semiconductors in solar panels are monocrystalline silicon, polycrystalline silicon, and thin-film solar cells.

Solar Inverters Convert DC to AC

Solar panels generate DC power, meaning they flow exclusively in one direction. However, your household appliances operate on alternating current (AC), which implies that electricity flows in both directions.

Thus, the solar electricity your panels generate must be converted from DC to AC before being used in your home. To convert DC power to AC power, you'll need an inverter, the type of which is determined by the size and design of your home solar system.

The inverter is necessary to provide power. It also allows you to link your solar panel system to the internet, giving you access to information regarding its performance. This will enable you to compare your solar energy production and household energy usage to determine whether the system is performing effectively and supplying your electrical load as needed.

Solar Charge Controller to Protect System

Solar inverters feed the converted AC electricity into your home's electrical panel. From there, energy is sent throughout your home to all of your outlets, ensuring that when your devices need to be plugged in, there is a functional electrical current accessible. If a fault or surge occurs, the solar charge controller can also turn off the flow of electricity to an electrical circuit to prevent overload in electrical lines, which can cause damage.

A charge controller is a tool that regulates voltage and current to prevent batteries from being overcharged. It controls the voltage and current that move from the solar panels to the battery. "12-volt" panels typically generate voltage ranging from 16 to 20 volts. Without regulation, overcharging can damage the batteries. Batteries usually need around 14 to 14.5 volts for a full charge.

Utility Meter Records Consumption & Production

The electric meter in your home is a device used by your utility company to measure your electricity consumption so that they can bill you correctly each month. However, if you use solar energy, you can use electricity from your solar panels, reducing the amount of electricity you need from the grid. Then, you save money by not paying for electricity from the utility provider. As a result, smart metres are installed in the majority of solar-powered households.

Batteries Store Excess Energy

Installing solar battery storage is critical for realising the long-term benefits of choosing solar. Excess energy generated by solar PV panels can be stored in a solar battery. Electricity will be available when the sun sets or it rains.

A solar battery is a beneficial component of any solar energy system. It allows you to store excess electricity for usage when your solar panels aren't producing enough energy, giving you more alternatives for how to power your home. Lithium-ion batteries are the predominant solar battery type in use today. This is the same technology used in cell phones and other high-tech batteries. Jackery Portable Power Stations use lithium-ion batteries to provide a smooth and efficient charging experience.

How Does A Solar Generator Work?

The solar generator works on the same basis as solar energy. Solar generators can produce off-grid energy constantly for long periods, requiring nothing but the sun's power. A portable solar generator consists of a power station and a solar panel. The power station stores energy in batteries, while the solar panel turns sunlight into electricity. The solar generator can provide power during disasters or unforeseen events.

Solar generators are gaining popularity as a portable power source since they are clean and renewable. Solar generators may power tiny appliances like lights, phone chargers, and larger goods like televisions and refrigerators.

During power outages, they are also becoming popular backup power sources for homes and businesses. Solar generators can be utilised in various applications, making them ideal for portable electricity.
