Solar Energy Definition and Examples
In simple words, solar energy refers to the Sun’s radiant heat and light, which can be gathered in a variety of ways, including solar light energy, solar thermal energy, and water heaters.
On a much wider scale, solar thermal collectors can create energy for thousands of people at once. Solar-thermal power plants create electricity using a variety of methods. The sun’s energy heats water, which then powers a steam turbine, which provides electricity in the same manner that nuclear power plants or coal do.
Solar energy for kids
Solar energy has the benefit of being easily used by both residential and business customers because it does not require the same massive infrastructure as geothermal or wind power. Solar energy serves not just the individual owner, but also the environment.
10 Uses of Solar Energy
Solar Water Pumping – How well do solar water pumps work?
Solar energy is used to power irrigation pumps. Pumping water is most necessary during the hot summer months, when solar radiation is at its highest, making this technology perfect for irrigation.
Water pumping is also lowered during the winter, when solar radiation is low, because crop transpiration losses are lower.
Solar Battery Charging – Do solar battery chargers really work?
Using a solar photovoltaic (PV) panel configuration, almost any battery-operated device may be recharged using solar energy. Solar PV panels generate a DC output, that is the same as that used by most batteries.
Many low-cost solar panel systems feature connections for charging cell phones, tablets, and laptops directly.
What is a Solar Furnace?
In a solar furnace, high temperatures are achieved by concentrating the sun’s rays onto a sample using a variety of heliostats (turnable mirrors) set on a slanting surface.
Heating can be done without polluting the substance you want to heat, and the temperature can be easily controlled by shifting the focus position. In metallurgical and chemical operations, this is especially useful.
One major potential application of solar furnaces is the production of fertilizers and nitric acid from air.
Can you power a Home with solar panels?
Solar energy is capable of powering an entire home. Solar panels are actually a pretty basic concept despite their unfamiliar and technical appearance. Solar panels contain polycrystalline silicon which responds to sunshine by generating a mild electric current. These panels (usually located in an open area or on a roof) are oriented to face the sun in order to capture and convert its radiant energy.
The resulting direct current (DC current) is passed through an inverter, which transforms it to alternating current (AC current power). This alternating current power is fed into the main electrical switchboard, where it is used to power the lighting, appliances, and gadgets of the home in the same manner that utility electricity is.
What is passive solar heating?
Solar radiation can pass through a greenhouse’s transparent walls, but the heat radiation generated by the plants inside cannot. As a result, the heat is confined inside the greenhouse, causing the temperature to rise.
The air in the greenhouse traps CO2 since the greenhouse is closed off to the outside environment – good news for the plants that need CO2 to live. Because of the controlled transpiration, moisture loss is reduced. All of these factors influence plant growth during the day, night, and all throughout the year.
How does solar Water Heating work?
Water can be heated with solar energy as well. The majority of solar water heating systems produce hot water for domestic use. Solar water heaters use a rooftop cell to absorb heat from the sun and deliver it to a storage tank.
Solar energy can also be used to heat swimming pools. Before being pumped back into the swimming pool, water flows to a collector where it is heated by sunshine.
The payback period for solar water heaters is usually five to ten years.
What is the use of solar lighting?
Solar lights are increasingly popular, with uses ranging from home gardening to security lighting to street lights and road signage. Solar lighting systems for your home are generally inexpensive and readily accessible in a variety of styles, ranging from simple to high-end. They can be purchased through online retailers such as amazon.com or at your local hardware store.
What is solar water distillation?
In arid, semi-arid, and coastal areas, potable water is scarce. Because of the abundant sunlight, solar distillation can be used to convert saline water into drinkable distilled water in these areas. This method uses a clear airtight glass lid to transfer solar rays into a shallow darkish container with saline water.
What is advantage of solar water distillation?
Solar radiation penetrates the brine (impure salty water) through the covers, where it is collected and converted to heat, causing the water to evaporate. The vapors formed are condensed in the cool interior of the roof to produce pure water.
Condensed water flows off the sloping roof and collects in troughs at the bottom before being pumped into a water storage tank to provide drinkable distilled water for areas where it is needed.
Industrial Uses of solar power
Industrial sites require more electricity than residences and commercial functions due to the use of heavy equipment and machinery. Power can be generated using solar energy, reducing electricity costs. It can also be used to prevent corrosion in pipelines.
What is solar ventilation system?
Solar ventilation systems, such as solar attic fans, can be used to cool a home during the summer while also lowering the burden on the HVAC system. For those who are unable to install a solar PV panel system that can completely support their household’s electricity demand, this may be an alternative option.
Industrial and commercial applications also include solar ventilation solutions, which can preheat a building’s air in cold places while saving electricity.
Solar Energy Advantages and Disadvantages
Advantages of Solar Energy
- It is eco friendly.
Solar energy not only helps you minimize your carbon footprint, it is also environmentally friendly because it emits no toxic substances (like fossil fuels) and there is no noise pollution (like wind turbines).
- It is a renewable energy source.
Sunlight is a natural phenomenon that is impossible to deplete through use. Solar energy is a renewable energy source that may generate electricity as long as the sun is visible.
- It can be used in rural areas.
Solar energy is ideal for rural communities where installing powerlines would be difficult or expensive. To generate solar energy, solar panels can be placed wherever there is sunlight.
Disadvantages of Solar Energy
Solar is Weather Dependent
Even though solar energy can be collected on rainy or overcast days, the efficiency of the solar panel system is diminished. Solar panels should be exposed to the sun in order to effectively capture solar energy. As a result, even a few gloomy rain storms can do significant damage to the energy infrastructure.
Solar Panels Need a Lot Of Space
Solar PV panels occupy a large amount of space, and some rooftops aren’t large enough to accommodate the required number of panels.
How Does Solar Energy work?
In a solar cell, photons clash with atoms and knock the electrons loose. Connecting conductors to the negative and positive sides of a cell creates an electrical circuit. Electricity is generated when electrons pass across this circuit.
A solar panel consists of many cells, while a solar array is made up of many panels or modules. The greater the number of solar panels installed, the more electricity is created.
Simply said, solar energy collects the sun’s energy and converts it into clean, electrical power for homes and businesses.
Solar Energy Facts
- Solar energy is the most rapidly expanding energy source.
The number of solar systems installed in the United States topped 2 million in early 2019
- Since 1839, solar energy has been used to generate electricity.
The photovoltaic effect, or the capacity to generate an electric charge from the sun’s rays, was discovered in 1839 by Alexandre Edmond Becquerel.
- Solar panels can generate electricity even when there is no direct sunshine.
Even if the sun isn’t directly shining on the panels – or if it’s misty – the colors reflected from the sky are captured and used by the solar panel cells.
- Solar adds to the worth of a home.
Solar-powered homes have been shown to sell more quickly and for a higher price than conventional dwellings. According to a Zillow survey from 2019, solar-paneled homes are worth 4.1% higher than an average household lacking solar panels. Solar panels usage is also tax-free in most states.
- Solar cells are the quickest to install energy sources.
Solar power generation is quite simple and basic when compared to other types of energy collection.
What is solar energy in simple words? Solar energy is one of the most popular forms of renewable energy. Solar power is generated by using solar panels to convert sunlight into electricity.
Renewable energy is already becoming a more common part of our daily lives. Technology will continue to drive new uses for solar energy that has the capacity to improve our lives and contribute to a cleaner planet.
