Dive into the below sections to understand better.

What is Solar Energy and its Advantages?

Solar Energy Basics

Solar energy is a powerful renewable source of energy extracted from the sun. It primarily powers up electrical appliances in residences and commercial places. When solar energy falls on the earth within an hour, it is utilized by everyone on the earth. With technological innovations and advancements, solar energy was trapped to convert into usable energy for buildings. The solar energy systems were designed with supportive energy efficiency features to supply power seamlessly. Two major types of solar energy systems are Photovoltaic Systems and Concentrated Solar Power Systems.

Types of Solar Energy Systems

1. Photovoltaic (PV) Systems

Photovoltaic PV systems are non-mechanical devices that convert solar energy directly into electric energy. Photovoltaic cells are known as solar cells. It converts the sunlight into electric power. The semiconductor materials of the cells get exposed to light. It further absorbs the sun’s energy and converts it into negatively charged particles or electrons. The energy captured lets the electrons flow through the semiconductor material to form an electrical current. Photovoltaic Systems are commonly used for residences and commercial places. Its passive solar design is suitable for heating and cooling.

2. Concentrated Solar Power (CSP) Systems

The CSP system is a solar energy technology that utilizes mirrors to reflect the sunlight and concentrate it onto a receiver. The energy extracted from the concentrated light heats up the high-temperature fluid. This process is known as thermal energy. It is further used to power up an engine or spin the turbine for electricity generation. This solar energy system is used for heavy utility-scale projects.

Advantages of Solar Energy

Solar energy has endless benefits for mankind and the environment. It is completely eco-friendly, aiding the ecosystems. Apart from being energy efficient, there are other advantageous features of solar energy.

As discussed earlier, being a renewable energy source, it will reduce carbon emissions. Carbon monoxide and carbon dioxide will no more affect the environment. High energy bills are a major concern with the usage of multiple electronic appliances. In such cases, solar energy will be a great aid. With the help of the solar energy system, when your electric appliances are powered, the energy bills will be dropped. Therefore, it is a cost-effective solution.

However, the money you will save depends on the solar system size and electricity usage. Especially for commercial places, it will be a great benefit. The larger the solar energy system, the maximum amount of money will be saved on your energy bills.

Solar energy systems have diverse applications. It can be utilized to generate electricity in remote areas where there is no access to energy grids. Solar energy will help to supply clean water in different regions and also helps to power up satellites in space. Moreover, solar panel installation will improve the home’s value. Solar energy systems also don’t require high maintenance. Regularly cleaning the system and yearly checkups are enough to enhance its life span.

The Need for Solar Energy Storage

The need for solar energy storage is vast. With the evolving generation, the importance and demand of solar energy are rising. The global solar energy storage market reached USD 9.8 billion in 2021. It is expected to reach USD 20.9 billion by 2031 with a CAGR of 7.9%. The demand is rising high due to the below reasons.

Energy Demand and Supply Variability

Solar energy systems are noticing massive demand. The electricity is still generated even when the sun is not shining. The storage system still allows the energy to convert into electricity. It smooths out variations to let the energy flow on the grid. The variation is based on the system type, whether it is photovoltaic panels or concentrated solar-thermal power systems. These systems are the two major variabilities that have their own working mechanism.

Increasing Renewable Energy Penetration

A major increase in renewable penetration has been noticed since 2005 due to the use of solar PV. As the penetration of solar energy generation progressed, it resulted in economic benefits and emissions savings. It has contributed to zero greenhouse gas emissions and reduced air pollution.

Enhancing Grid Stability and Reliability

Solar energy storage with cutting-edge technology controls the impact of solar energy on the grid. It helps the system to function with reliable measures and preserve grid stability. The storage devices store sufficient solar energy and deliver it efficiently to the grids when energy output slows down. It further helps in managing the grid’s frequency and voltage.

Maximizing Self-Consumption

Solar self-consumption can be maximized by pairing a solar panel system with a battery setup. With battery usage, the excessive energy amount generated by the solar panels is stored safely to use later.

Selecting the Right Solar Energy Storage Solution

It is important to choose the right solar energy storage system which meets your energy demand all day. For residences and commercial places, the energy needs will vary with huge consumption differences. Commercial sites need specialized storage systems to meet their energy needs. Before investing in a solar energy storage solution, here are the factors to consider.

1. Storage Capacity

The storage capacity depends on the system’s size. You will get a variety of options in capacity. It is the amount of electricity stored and supplied to your place. You have to decide the system type and size based on your energy needs.

2. Depth of Discharge (DoD)

Depth of Discharge is another important factor to consider before installing the storage system. It is the battery’s percentage discharged relative to the total capacity.

3. Round-Trip Efficiency

It is the percentage of electricity stored in the energy system which can be retrieved later. Go for a storage system with higher round-trip efficiency to control the energy loss in the process.

4. Life Cycle and Degradation

The life cycle varies based on solar energy storage systems. The operational lifespan of a PV system is around 30-35 years. At the same time, concentrated solar energy storage can last around 20-25 years.
