Which of the Following Is Used to Harvest Solar Energy
Harvest solar energy efficiently with photovoltaic cells, solar panels, and concentrated solar power systems – renewable energy sources to meet your energy needs.
Reduce your electricity bills by 90%
Did you know that one hour of sunlight can power the world for a year? This shows how powerful solar energy is, as it’s clean and endless. We use different technologies to capture this abundant energy from the sun.
There are several ways to collect solar power. These include using photovoltaic cells and capturing heat energy. Solar water heaters and special power plants are also common. Photovoltaic cells turn sunlight into electricity. At the same time, heat-capturing methods use the sun’s rays to warm up surfaces, particularly useful for heating water.
To heat water, solar panels with black surfaces are used. Vacuum tube systems also help efficiently move solar heat into water tanks. For producing electricity, molten salt power plants reflect sunlight onto a central tower. This process heats up salt to create steam, turning turbines that make electricity.

Introducing Solar Energy Harvesting
Solar energy harvesting means capturing the sun’s energy and turning it into electricity or heat. It’s a key part of renewable energy. It helps us use less fossil fuel and is better for the planet.
What is Solar Energy Harvesting?
Solar energy harvesting uses the sun’s energy to make power. It includes solar panels, systems that heat water, and big solar plants. They change sunlight into power we can use.
Why is Solar Energy Harvesting Important?
Solar harvesting gives us a clean, endless source of power. It’s key as we work to cut pollution and switch to green energy. Solar power lets us reduce the use of fossil fuels and protects our planet.
Photovoltaic Solar Panels
Today, photovoltaic (PV) solar panels are the leading way to gather solar energy. They use PV cells, which are made of two types of semiconductor wafers. These wafers can create electricity when light hits them. This happens across all PV cells, leading to a lot of electricity being produced.
How Photovoltaic Cells Work
The photovoltaic effect is key in turning sunlight into electricity. When sunlight hits a PV cell, it makes the cell’s electrons move freely. This movement creates an electric current. We can then capture this current and use it as power.
Types of Photovoltaic Cells
There are two main types of PV cells: monocrystalline and polycrystalline. Monocrystalline ones come from a single silicon crystal and work a bit better. Polycrystalline cells come from many silicon crystals and are a bit less efficient. Despite being more costly, monocrystalline cells are known to perform better.
Advantages of Photovoltaic Solar Panels
PV solar panels offer many benefits. They make clean energy without polluting. This is great for the planet. They can also grow with your needs because of their design. This means you can start small and add more panels later.
Another big plus is their low upkeep. With no moving parts, they are quite durable. They can keep making power for many years with little maintenance. This saves you money in the long run.
Thermal Energy Harvesting
Aside from solar panels, the sun’s heat can be harvested. This method uses the sun’s heat by using its infrared radiation. This energy is then absorbed by certain materials.
Black Body Radiation
“Black bodies” are materials that absorb and emit all wavelengths of sunlight. They are key to understanding thermal energy harvesting. This is because they efficiently absorb and emit radiant heat.
Applications of Thermal Energy Harvesting
For centuries, people have used thermal energy in heating systems. This includes Roman baths and Ancient Egyptian houses. Today, we use it in things like solar panels for heating water.
While it’s not great for large energy production, it helps at home. It works well with solar panels, giving us a more complete use of solar power.
Solar Water Heaters
Solar water heaters are used a lot in areas with lots of sun. The basic model has a pump moving cool water through a dark panel. This panel absorbs the sun’s heat well, warming the water. The water keeps moving through the system, staying warm thanks to the sun’s energy. With some designs, a pump isn’t needed. The warm water naturally rises, and the cold water sinks, moving by itself in a cycle.

Fenice Energy is dedicated to offering sustainable energy. In India, they help both homes and companies switch to solar water heaters. This move saves money over time and helps the environment.
Vacuum Tube Solar Water Heaters
Vacuum tube solar water heaters are innovative and efficient. They use advanced systems like self-contained heat pipes. These heat pipes move heat to a different tank. Radiant energy enters through the vacuum, but it stays there as thermal energy. The heat pipe then moves this heat to a big water tank. This way, they work well even in the cold. They keep almost all the heat and use it to warm water.
How Vacuum Tube Solar Water Heaters Work
These heaters work by capturing and keeping thermal energy really well. A vacuum inside the tubes stops heat from escaping. So, the solar energy they catch goes straight to heating water. This feature helps them stay hot, even when it’s cold outside. Hence, they’re great for places with changing weather.
Benefits of Vacuum Tube Solar Water Heaters
Vacuum tube solar heaters do more work and use less energy. They’re better at turning sunlight into hot water. This means more shower time and less money spent on electricity. The design of these systems also helps them survive rough weather. They last longer and need less upkeep. All these benefits have made them a top pick for homes and businesses. They help grow the use of clean energy in places like India.
Molten Salt Solar Power Plants
Recent advancements in molten salt systems have greatly improved solar power generation. These plants use sunlight to heat salt until it’s a liquid. This hot liquid then heats water, turning it into steam that powers a turbine to create electricity.
The Process of Molten Salt Solar Power
The Ivanpah Solar Plant and others work by concentrating sunlight with many mirrors onto a central tower. At this tower, the heat from all the mirrors melts the salt. This molten salt can then be stored and used to create energy, even at night.
Examples of Molten Salt Solar Power Plants
In California, the Ivanpah Solar Plant has 173,500 mirrors focusing sunlight onto three towers. This process generates 392 megawatts of electricity by melting salt to power the turbines. In Morocco, the Noor III plant can make 150 megawatts using a similar setup.
Concentrated Solar Power Systems
Concentrated solar power (CSP) systems are a new way to use the sun for making energy. Instead of changing sunlight into electricity directly, they use big mirrors or lenses. These focus a lot of sunlight onto a small area. Then, that area gets very hot and creates steam. This steam runs turbines to make electricity.
How Concentrated Solar Power Works
The core idea of CSP is to turn sunlight into very hot heat. This heat powers a traditional generator through steam. By gathering sunlight over a large space and putting it onto a tiny spot, temperatures can get really high. We’re talking about 400 to 800 degrees Celsius (750 to 1,470 degrees Fahrenheit).
This way, the steam created can power turbines to make electricity. It’s a lot like how regular thermal power plants work.
Types of Concentrated Solar Power Systems
There are a few kinds of CSP systems, each working in its way. Let’s look at them:
| Type of CSP System | How it Works | Key Features |
|---|---|---|
| Parabolic Trough Collectors | Curved mirrors focus sunlight onto a receiver tube containing a heat-absorbing fluid, such as oil or molten salt. | Widely deployed, cost-effective, and can store thermal energy for use during cloudy periods or at night. |
| Power Tower Systems | A field of mirrors (heliostats) reflects sunlight onto a receiver at the top of a central tower, where the heat is used to generate steam. | Able to reach higher temperatures and achieve greater efficiency, but require more complex engineering and tracking systems. |
| Dish-Engine Systems | A parabolic dish-shaped concentrator focuses sunlight onto a receiver at the dish’s focal point, which powers a small electrical generator. | Highly efficient and modular, but more expensive and less scalable compared to other CSP technologies. |
