The process of collecting and storing energy generated by solar panels or solar photovoltaic (PV) systems for later use is referred to as solar energy storage. Solar energy is a renewable & sustainable, and environment-friendly energy source, although it is intermittent and is affected by weather and time of day. Solar energy storage systems are intended to solve this intermittent nature by storing extra energy when the sun shines and making it available for use when the sun is not producing electricity, such as at night or on cloudy days.
The forthcoming years are expected to influence the energy storage market due to the progression of the renewable energy domain, favourable government policies and programs for energy storage systems (ESS), and improved economics of energy storage.
However, a potential impediment to market growth soon is the discord between the demand and supply of essential raw materials like cobalt, lithium, and graphite.
Additionally, in the (C&I) sector, the adoption of renewable energy sources for powering buildings is rising. Yet, the intermittency of renewable energy poses reliability challenges for the C&I sector's energy needs, leading to underutilizing these resources. This trend is likely to drive the increased adoption of energy storage systems within the C&I sector, aiming to enhance the integration of renewable energy. This shift creates substantial opportunities for energy storage system providers in the forthcoming times.
