Solar Battery Market Growth Factors

Supportive government regulations for the use of photovoltaic technology

According to the US Solar Energy Industries Association (SEIA), the government has implemented laws, such as net metering and commonly solar, to promote photovoltaic technology to generate electricity. Consumers can utilize photovoltaic energy for their own electricity needs and sell the remaining solar power they do not use in countries like the US, Spain, and France. The Chinese solar photovoltaic industry has witnessed significant growth compared to other countries.

According to the China Photovoltaic Industry Association, China's capacity for photovoltaic energy grew by 34% year-on-year in 2018. Total installed PV capacity surpassed 170 gigawatts at the end of 2018 compared to 136 gigawatts in 2017. These regulations promote the use of photovoltaic technology. Therefore, these regulations are expected to impact the solar battery market positively. In addition, the demand for solar batteries is expected to rise significantly with the increased use of photovoltaic technology.

Increasing focus on renewable energy storage solutions

As per the International Energy Agency (IEA), the need for renewable energy has risen since 2015.

• For example, the annual solar PV capacity in 2017 reached 100 GW, showing an increase of 31% from 2016. The increased demand for PV technology is accredited to the rise in demand for sustainable energy resources, minimized carbon emission reduction, and dependency on conventional fuels. Furthermore, in 2019, solar PV witnessed a growth rate of 22% among other renewable energy sources like wind and hydro energy, owing to the rising demand for energy from developing countries like India, China, and Thailand. The increasing demand is attributed to rapid industrialization and urbanization.

In addition, the implementation of stringent government regulations to reduce carbon emissions produced due to the usage of conventional fuels has led to an increase in the performance of photovoltaic technology for electricity production. The need for solar energy is predicted to increase with the rise in demand for renewable energy. Therefore, the market for solar batteries is expected to increase.

Restraining Factors

Costly initial installation

Solar batteries are generally costly, which is a threat to the market. Solar power has to be used right away while stored in large batteries. These batteries, utilized in off-the-grid solar systems, can be charged throughout the day to use the energy at night. However, energy demand is generally higher during the day, and there is a need for installation and proper storage of solar energy. The cost of energy storage is relatively high and can quite quickly increase the cost of solar PV systems substantially. Therefore, installing an energy storage system depends on the consumption tariff rate.

Market Opportunities

Breakthrough in energy backup systems

Shortage of solar radiation and foggy weather can impact the efficiency of solar storage. However, the backup system as a part of the solar collector aids in the additional storage of solar heat during cloudy or foggy weather. It maintains the same performance as a solar battery even on cloudy days and overcast weather. Hence, such advancements are expected to create lucrative opportunities for market growth.

Regional Insights

Asia-pacific: dmonant region

Asia-Pacific dominates the regional market with more than 40% revenue share. It is estimated to reach an expected value of USD 215 million by 2030 at a CAGR of 17.5%. This is attributed to a rise in concern from governments across emerging nations, such as China, India, and South Korea, regarding zero-emission norms. However, China, the largest producer of solar power, is expected to foster the market's growth in Asia-Pacific further. In addition, the growing number of investment opportunities in new solar power projects will further influence the market growth in this region. For instance, in March 2021, VRB Energy signed an agreement with Xiangyang Municipal Government to build a 100 MW solar plant with a vanadium flow battery.
