Different Types of Active Solar Energy

Solar energy is one of the most abundant and accessible sources of renewable energy. The sun provides light, warmth, and mobile nutrients for all living things. By simply changing a few habits and wearing more sun protection, you can harness the power of the sun to generate electricity that you can use anywhere you go.

There are many different types of solar energy, and it can be used for a variety of different purposes. Some people prefer to use solar energy for heating their homes, while others use it to power computers or charge electronic devices. Sometimes, people use it to power cars and other vehicles. Although each one of these applications requires a different type of solar energy system, the basic principles behind them are all the same.

Direct Use

If you are unable to purchase or build a dedicated solar energy system for one purpose, you can use it for a variety of different tasks. The most basic form of solar energy is direct use. With this type of setup, you are relying on the sun to directly provide the energy your device needs. It is a very simple and straightforward system, and it is highly dependable. You can use it for powering electronics, lighting, and small appliances. It is also great for pumping water because it does not require any additional energy to operate.

Indirect Use

If you have a larger space that you want to utilize, or if you want to be able to use solar energy at multiple locations, you can incorporate an indirect use system. This system uses a central server or powerhouse to store and/or manage the energy that is generated at the individual locations. The remote units (solar panels) connected to the server have a variety of functions; however, they all work together to generate power and heat as the sun moves across the sky.

This type of system is very reliable because it has a backup power source in the event of a temporary blackout. When the sun is shining, the units generate electricity, and when there is no sun, they begin to lose energy, but still provide some heat. The more solar panels you have, the harder it will be for the system to lose energy. When the sun is directly overhead, it will be challenging to generate any power at all without capturing at least a little bit of heat. The more solar panels you have, the higher the chance of capturing some heat energy when the sun is directly overhead. An indirect use system can also be integrated with a chiller, and when combined with a heat pump, you can utilize the power of the sun to create a more efficient and comfortable indoor climate.

Pelagic

This type of system is generally used in areas where there is a lot of water and no electricity available. The units are mounted on towers or stilts above the water, and the water is used to cool the devices during the day. When the sun begins to set and the water becomes a bit cooler, the devices switch to night mode, and they begin to generate electricity as the water gets colder. The disadvantage of this type of system is that you need to live somewhere near a body of water for it to be effective.

Reflective

The reflective type of solar energy system is very similar to the pelagic system, but instead of putting the devices on stilts, you would place them on the ground and cover them with solar protection material. Most commonly, this material is made of tilted panels that are covered with aluminum foil or some other reflective surface. This type of system is very effective because it does not require any additional energy to operate. It simply reflects back at least some of the energy that is naturally available from the sun.

Thermal

These systems are used for generating steam or hot water, and the heat can be utilized for various purposes. A thermal solar energy system usually consists of a boiler, a heat exchanger, and a fan. The boiler is where you generate the steam, and it is usually associated with a solar chimney or tower. The boiler’s function is to take the heat from the sun and turn it into steam that can be used to power various appliances and machines. The disadvantage of this type of system is that it is very noisy, which makes it difficult to use in private homes.

Ocean Thermal

This system incorporates a heat exchanger, a boiler, and a fan to create a loop, and it utilizes the temperature change in sea water to generate electricity. For it to be effective, you need to be at least a few hundred meters from the coast, as the temperature of the water gets significantly lower the farther you get from the coast. The advantage of this type of solar energy system is that it is very reliable because most of the components are made of steel or other durable materials and it does not require any additional maintenance. The disadvantage of this system is that it needs a lot of space to be effective, as you need to incorporate a large tank to store the heat absorbed by the sea water. Additionally, this system is not suitable for generating electricity for private use.

Off-Grid

This type of solar energy system is generally used in areas where there is no power grid available or if the power grid can’t supply the energy needs of a home or business. Off-grid solar energy systems usually incorporate a storage unit that is connected to a microgrid, which is in turn connected to multiple remote units. These remote units make up the entire system, and they are usually associated with a wind turbine or water turbine. When the wind or water is blowing, the units turn on and generate electricity. When there is no wind or water flow, they switch off and begin to lose energy. The disadvantage of this system is that if there is no power grid available, you will need to generate your own electricity using other energy sources, such as fuel oil, gas, or wood. The advantage of this system is that it can be used for various tasks and in various locations because it does not require any additional connections or maintenance. Additionally, it is reliable because it does not require any additional energy to operate.

Hybrid

This system is like a combination of the above, incorporating aspects from different systems to create a unique solution. The remote units of a hybrid solar energy system are usually made of a gear pump, a turbine, and a generator. The purpose of the gear pump is to take the energy from the turbine and transfer it to the generator. The generator’s function is to produce electricity from the energy transferred by the gear pump. The disadvantage of this system is that it is very expensive to purchase and install, and it requires a lot of maintenance. The advantage of this system is that it can utilize several different types of energy, which makes it more flexible than other types of solar energy systems.

Converter-Charger

This type of solar energy system is also known as an additive hybrid solar energy system because it can store energy in both a chemical and an electrical form. The solar panels of a converter-charger system are usually connected to an inverter, which changes the direct current (DC) voltage output of the panels to an alternating current (AC) voltage that can be utilized by an electronic device. For example, the inverter could change a 200-volt DC source into an alternating current of around 22 volts, which is suitable for powering small electronics and appliances. The disadvantage of this system is that it requires a large storage battery to operate, which can be problematic if there is no AC power available at the time, such as in the case of a dead battery or a brownout. Additionally, this system takes up a lot of space because of all the extra components it requires.

The above are just a few examples of different types of solar energy systems. There are multiple other variations and combinations of these systems that can be used for various purposes. If you want to utilize the power of the sun for electricity generation, there are a variety of different ways to do it. It depends on your budget, needs, and where you want to put the equipment.
