What Type Of Energy Is Solar Energy

How Exactly Is Electricity From Solar Energy Produced

Solar panels are usually made from silicon installed in a metal panel frame with a glass casing. When photons, or particles of light, hit the thin layer of silicon on the top of a solar panel, they knock electrons off the silicon atoms.

This PV charge creates an electric current , which is captured by the wiring in solar panels. This DC electricity is then converted to alternating current by an inverter. AC is the type of electrical current used when you plug appliances into normal wall sockets.

How Many Types Of Energy Are There

There are six basic forms of energy: chemical, electrical, radiant, mechanical, thermal and nuclear.

What are the 7 types of energy? Energy exists in many different forms. Examples are: light energy, thermal energy, mechanical energy, gravitational energy, electrical energy, acoustic energy, chemical energy, nuclear or atomic energy and so on.

What Is Solar Power

Energy created by the heat and light of the sun is called solar energy. Solar power is produced when energy from the sun is converted into electricity or used to heat air, water or other substances. Solar energy can be used to create solar fuels such as hydrogen.

At the end of 2020, there was more than 700 GW of solar installed around the world, meeting around 3 percent of global electricity demand.

More solar PV energy is added each year than any other type of energy generation, thanks largely to the rapid cost reductions that have been achieved in recent years. Between 2010 and 2019, the global levelised cost of electricity for large scale solar dropped by 85 per cent.

The Future Looks Bright

However, there is light at the end of the tunnel. There are new forms of power plants being introduced that rely solely on solar power.

These power plants use the sun as a heat source and can do so in 3 different ways:

Parabolic-Trough System

This system captures the suns energy via long rectangular, curved mirrors angled toward the sun, enabling sunlight to focus its super rays onto a pipe that contains oil.

This oil is then heated and then used to boil water in a conventional steam generator to produce electricity.

Dish/Engine System

These systems use a large, mirrored dish that resembles your household satellite dish . This dish concentrates the suns heat onto a receiver. The receiver then absorbs the heat and transfers it to the fluid within an engine.

Heat causes this fluid to expand, pushing against a piston or turbine and producing mechanical power. Finally, mechanical power runs a generator or alternator to generate electricity.

Power Tower System

Power tower systems use large fields of mirrors that concentrate the suns sunlight onto the top of the tower. On top of the tower, there is a receiver containing molten salt.

The salts heat can generate electricity through a conventional steam generator . Molten salt effectively retains heat efficiently and can be stored for days until it needs to be converted into electricity. This means electricity can still be produced on cloudy days or even at night.

What Are The Most Common Types Of Solar Energy

Solar power technology is divided into two main categories: solar photovoltaic, which uses sunlight to create electricity, and solar thermal, which uses heat from the sun to create electricity. Solar photovoltaic technology is more common, but solar thermal technology has the potential to be more efficient in the future.

Solar photovoltaic technology is based on the principle of photoelectricity. When light hits a semiconductor, such as a solar cell, it causes electrons to be freed. These electrons can then be turned into electricity by an electric current.

Solar photovoltaic cells are usually made from silicon. The silicon is covered with a layer of silicon dioxide, which helps to prevent the cell from being damaged by the suns ultraviolet ays.

Solar photovoltaic cells can be installed on roofs, in windows, or on the ground. They can be small, like a credit card, or large enough to power a whole house.

Solar thermal technology uses the suns heat to create electricity. Solar thermal technology can be used to power homes, office buildings, and factories.

Solar thermal technology uses two main types of systems: direct thermal conversion and indirect thermal conversion.

Direct thermal conversion uses sunlight to heat a liquid or gas. The heat from the sun turns the liquid or gas into a hot liquid or gas, which can then be used to generate electricity.

How Is Solar Energy Changed Into Chemical Energy

Ok, so lets say you have a sunny day and you decide to take your laptop outside and enjoy the rays. As youre out there, you absorb the energy from the sun, converting it into heat. This heat then travels through your laptop and is used to turn the crank that powers the computer.

Now, imagine if you were outside during the night. The sun has already set, so all of the energy it provides is in the form of light. This light travels through the air and hits the ground, bouncing off of things and eventually reaching your eyes. This light is what we call sunlight.

When sunlight hits the ground, it starts to heat up. The heat from the sun is so intense that it can break down molecules that make up Earths atmosphere, called water vapor. When this happens, all of the water vapor in the air turns into a liquid form called water. This liquid water then starts to flow downhill, absorbing energy from the sun along the way.

This energy is turned into heat, which then travels back up to the ground. This heat is what heats up the water that was flowing downhill, and it eventually makes its way into our laptops.

What Is The Difference Between Active And Passive Solar Energy

Solar Energy is what we receive from the sun. Its a free and abundant source of energy that can power our homes, businesses, cars, etc

The difference between active and passive solar energy is that active Solar Energy uses technology to capture solar radiation in order to produce electricity while Passive Solar Energy simply captures sunlight through certain materials or designs so it can be used for other purposes such as heating or cooking.

Costs And Integration Of Solar Water Heating Systems

Households and commercial spaces with installed solar water heaters have seen a drop of 50-80% in their water heating bills. Also, there are less likely to be any price hikes or fuel shortages because the sun is free. The average cost of installing a 100-gallon solar water heater is around $8000 to $10,000.

Is Solar Energy The Same As Light Energy

When people talk about light energy, they are referring to the energy that humans can see. This type of energy is called visible light. Visible light is made up of waves with a frequency that humans can see.

Other types of energy, called invisible light, are waves with frequencies that are outside of the visible light spectrum. Even though we cant see them, these waves are still out there!

Sometimes, when people talk about solar energy, they are referring to the energy that comes from the Sun. This type of energy is called solar light. Solar light is made up of waves with a frequency that is in the visible light spectrum.

So, solar energy is basically light energy, only with a different frequency.

Solar Energy Advantages And Disadvantages

Solar energy, as a green energy source, has undoubted attractions over fossil fuels, irrespective of the solar energy technology used photovoltaic or CSP.

These are the most important advantages of solar energy:

• Solar energy is a truly free and renewable energy source accessible from anywhere in the world, is available to some extent every day, and will never run out.

• Solar energy can be used to produce electricity in areas without grid access, and to power satellites in space. It emits no pollution into the atmosphere.

• Solar energy systems do not generally require much maintenance, with solar panels typically requiring cleaning a couple of times a year. They usually carry a 20 25 year warranty. Inverters may need changing after five to 10 years as they operate continuously, and cables also need maintenance.

• Technology in the solar panel industry is constantly advancing. Innovations in quantum physics and nanotechnology can potentially increase solar panels effectiveness and double, or even triple, their electrical output.

But there are also some solar energy disadvantages:

• Solar panel system costs remain high, although their price is dropping and can be expected to drop further.

• Also, their output levels depend on the strength or presence of sunlight, so are unpredictable. This can be mitigated by storing energy in large batteries, but battery systems are expensive to install and require maintenance.

• Some CSP systems are inefficient in their water usage.

Which Type Of Solar Energy Should You Use

The type of solar energy harvesting system you should use depends on your needs. Following are some quick questions that you should ask yourself to make a choice.

• Is a storage unit required?
• How much energy do I need on a regular basis?
• Am I ready to go full solar?
• Are my requirements commercial or personal?

These questions will help you understand your core requirements for a solar energy setup.

Types Of Solar Energy

There are many different types of solar energy systems.

Some are strictly for home use, some for large-scale commercial use, some create heat, and some create electricity.

It is easy to spilt the categories of the many types of solar energy systems in two ways: if the suns direct energy is harnessed into a heat energy form, or if the suns energy is converted into an electrical energy form.

When the suns energy is harnessed into heat energy, we mean that the the sunlight is essentially gathered and used for heating. For example, when you leave a parked car in the sunlight all day and the inside collects heat, or when the shallow end of a swimming pool becomes noticeably warmer as it harnesses the sunlight on a hot day. These examples of harnessing the suns heat can then categorized into two different solar energy types:

Passive Solar Energy: is the use of strategically oriented walls, windows, and architectural features usually of a home that are designed to absorb and deflect the suns energy without the use of any mechanical or electrical devices.

The goal of passive solar heating is to reduce the cost of electrical heating during colder months of the year, while also keeping a home cooler during the warmer months of the year.

The diagram below is a simple model of a home designed for passive solar energy.

Thermal Energy Storage Device

Thermal energy storage devices include sensible heat and latent heat storage devices while this sensible heat storage device includes water storage and pebble bed storage. When the material is heating, melting, or vaporized then the energy can be stored, we can heat a certain kind of material that is metal or liquid and store this heat energy inside that material when this process is reversed this heat can be extracted from such materials. When solid is heated and then melted then it has risen further in temperature so one solid material can store the sensible heat and latent heat at the same time.

Ratification Of The Kyoto Protocol

Australia ratified the Kyoto Protocol in December 2007 under the then newly elected Prime Minister Kevin Rudd. Evidence suggests Australia will meet its targets required under this protocol. Australia had not ratified the Kyoto Protocol until then, due to concerns over a loss of competitiveness with the US, which also rejects the treaty.
