Define Solar Energy
Photovoltaic (PV) solar energy harnesses solar energy to generate electricity that doesn’t harm the environment. Most PV panels use silicon or polycrystalline cells, which have been refined into materials that convert light from the sun’s visible spectrum into electricity. These materials are commonly called photovoltaic materials.
The PV effect occurs when photons from the sun hit these cells and free electrons from their atoms. These electrons can then flow through semiconductors materials to create an electric current. The PV solar cells used in modern technology do not use silicon alone but a combination of materials such as silicon and oxygen.
This method uses both photoelectric effect and photochemical processes to generate electrical energy. This is done by creating a gap between semiconductor layers letting tiny electrons move from one layer to another and join with hydrogen at an electrode of the solar cell, which is used as a source for current.
N-type and P-type semiconductors can generate electricity because they each have different electrical charge carriers; positive holes (P-type) and negative electrons (N-type). When photons hit the solar cell, they excite these charge carriers to move away from their respective atoms. As they try to return to their original state, the carriers travel in opposite directions, creating electricity. PV cells can convert some of the invisible or infrared light and ultraviolet light to electricity.
Types of solar energy
Photovoltaic Solar Energy
Photovoltaic cells are one of the most popular methods of harnessing solar energy for electricity. These silicon semiconductor panels can convert light from the sun or any other source that emits photons into electricity by letting loose electrons whose natural state is being attached to their atoms. Photons hit these cells and excite electrons by removing them from their atoms, allowing them to flow freely. This method does not harm the environment and is currently becoming one of the more popular harnessing solar energy.
Solar panels make use of photovoltaic cells in direct current (DC) power generation, which converts photons into electricity using semiconductors called N-type and P-type semiconductor materials. An N-type semiconductor material has an abundance of negative electrons, whereas P-type semiconductor material is rich in positive holes. These two semiconductors are the foundation for most modern technologies that use solar energy to harness electricity.
Solar Thermal Energy
Solar thermal energy is another requirement for harnessing solar energy that does not harm the environment. This method uses the fact that certain objects emit light when heated to extreme temperatures, which can be used to generate electricity in a process called the photothermal effect. Solar thermal cells can convert infrared rays into electricity using what are called thermoelectric cells. These solar thermal cells are composed of a type of semiconductor sandwiched between metal plates or bars to create a P-N junction. As the object heats up, electrons move from one end to another, used as direct current electricity.
Concentrated Solar Energy
Concentrated solar energy is another method that harnesses the sun’s rays. These panels consist of many individual photovoltaic cells jutted out in a fully automated robotic fashion to track the sun’s path across the sky throughout the day. This method can utilize all wavelengths of light emitted by the sun to create more significant energy than individual cells. The concentrated solar energy method is currently being used in many technology projects worldwide to harness the power of the sun’s rays.
Water Heating Solar Energy
Water heating solar energy is another method of harnessing solar energy. This process uses heat-resistant black paint to absorb the sun’s rays to heat water for various space heating or even cooking applications. These water heater panels can be placed in series or parallel to create even more significant energy than if the solar cells were used alone. This method is currently being used around the world to provide developing countries with clean, inexpensive electricity.
Solar Pool Heating
Solar pool heating uses similar technology to water heating panels, but the product is much smaller. These photovoltaic cells can be placed directly into a swimming pool or spa and then generate enough electricity to replace themselves over time continually. This particular method can provide an alternative for those who do not have access to conventional energy sources such as coal or natural gas and help save money by cutting down on the amount of electricity needed to heat a pool.
How does solar energy work?
To use solar energy, we first need to understand what it is and how it works.
Sunlight activates the panels
As sunlight activates the panels, they absorb it, and the solar energy knocks electrons loose from their atoms. This process of converting light (photons) to electricity (voltages) is called the photovoltaic (PV) effect. The solar cells are also connected in a circuit. When activated, these cells allow electrons to flow through them to produce electricity.
The cells produce electrical current
The solar cells are connected in a circuit, and when activated, they allow electrons to flow through them to produce electricity. Solar panels convert the sun’s light into usable solar energy. Solar panels convert most of the visible light spectrum and about half of the ultraviolet and infrared light spectrum to usable solar energy.
The electrical energy is converted
The electrical energy is converted into alternating current through the use of a power inverter. This energy is then supplied to homes where it can be used to power appliances that require alternating current. Solar panels can produce electricity even when the sun isn’t shining. As long as the sun’s rays can reach the solar panels, electricity can be made.
The converted electricity powers your home
An electrical inverter converts energy from a solar panel into an alternating current. This converted electricity powers your home and carries electricity to be used by any appliance that requires ac power. The inverter converts the energy from your home’s direct current (dc) electricity to alternating current (ac). Before it enters your residence, ac electricity is stepped up or down in voltage using a transformer. This process increases the voltage and decreases its potential energy to be used by appliances like lights and TVs.
A net meter calculates usage
Your net meter measures electricity usage at your residence, including the solar energy that you generate. When you use solar energy to power appliances within your home, the meter’s dial will run counterclockwise. If you use more electricity than what was produced by your solar panels during the day, the dial on your net meter will turn clockwise. If your home uses more electricity than it makes, you will have to pay for the difference.
Solar energy advantages
Solar energy is a type of radiant energy produced by the sun. It can be used for heating homes and other buildings, lighting, and the production of electricity. There are as many as five reasons why one should consider using solar energy as an alternative to traditional sources of power:
- Solar cells produce zero carbon emissions, which means that, unlike fossil fuels, they do not cause global warming.
- Solar cells are renewable energy sources since they will never run out of fuel like oil or natural gas, which means the supply is almost endless.
- Solar energy is available in abundance throughout the earth, making it an inexhaustible source of power.
- One can harness the power of the sun at any time.
- Solar energy is an easily accessible source of power since it does not need to be mined or processed before usage.
Frequently asked questions
How much does solar energy cost?
Solar energy is an affordable source of power. It costs less than other sources of energy, such as coal or oil. Even though the initial cost of installing solar cells may be high, they save in the long term.
How do I use solar energy?
One can use solar energy in several ways for heating, lighting, or producing electricity. The most common method is through photovoltaic technology that uses the PV effect to create an electric current. This current can then be converted into proper forms of power.
Can I use a meter to measure solar production?
Yes. Solar panels produce more energy during the day, and this can be measured through a meter called a charge control device (CCD). This is important to ensure that the batteries are not overcharged or undercharged.
Is solar power expensive to set up?
Solar power is expensive to set up initially, but it saves in the long run. Therefore it can prove to be a good value for your money.
What is the solar energy storage system?
Solar storage systems are another alternative for those who do not have access to conventional energy sources such as coal or natural gas. The system consists of a solar array, a battery, and an inverter. When solar panels produce more electricity than needed, the excess will be stored in the battery, and then it’s ready for use when we need it most. Solar storage systems can help you save money by cutting down on the electricity required to power your home.
Can I sell the electricity generated by my solar cells?
Yes. You can sell any excess power that your panels produce back to your power company through net metering. This billing method credits solar customers for the electricity they add to the grid. However, check with state or local laws regarding this issue because net metering policies are constantly changing.
What is the impact of radiation on batteries?
One should not leave their batteries exposed to direct sunlight because this can reduce battery life. Most batteries should be stored at a temperature of 15°C (59°F); the greatest permissible temperature is –40°C to 50°C (–40°C to 122°F) for most chemistries.
