Quarterly Analysis of Solar PV Installed Capacity in India: Q1 2021 to Q3 2023

The period from the first quarter of 2021 to the third quarter of 2023 has witnessed substantial transformations in India’s solar photovoltaic (PV) sector, significantly contributing to the nation’s renewable energy objectives. This column provides an in-depth analysis of the quarterly fluctuations in solar PV installed capacity during this timeframe, highlighting pivotal trends, challenges, and policy dynamics that have molded the sector.

In Q3 2023, the installed solar PV capacity experienced a notable decline of 44% year over year compared to Q3 2022, encompassing both rooftop and utility-scale installations. Despite this decline, the overall trajectory over the analyzed period shows consistent growth, reflecting India’s commitment to renewable energy goals.

The first quarter of 2022 marked a milestone with an installed solar PV capacity of 4.5 GW. This growth was attributed to the implementation of large-scale projects and the government’s dedication to renewable energy, exemplified by initiatives like the National Solar Mission. In 2022, the total installed solar PV capacity (including rooftop and utility) reached 13.2 GW, aligning with the final year target of 100 GW by 2022 set by the Jawaharlal Nehru National Solar Mission (JNNSM). The off-grid segment also contributed around 450 MW in the culmination of the JNNSM target.

Policy interventions played a pivotal role during this period, incentivizing solar investments and streamlining approval processes, thereby fostering the sector’s expansion. Accelerated growth was observed in Q3 and Q4 of 2021, driven by increased investor confidence and technological advancements. The adoption of cutting-edge PV technologies, along with a supportive policy environment, solidified India’s global leadership in solar energy adoption.

Despite facing challenges such as delays in project approvals and regulatory uncertainties; the solar PV sector continued its upward trajectory in 2022. Supply chain disruptions posed additional obstacles, slowing down installations in Q2, Q3, and Q4 of 2022. However, technological innovations and increased collaboration between the public and private sectors sustained growth, resulting in a total solar PV installation of over 13.2 GW in 2022.

The third quarter of 2022 brought about a stabilization of the market, with quarterly variations indicating a more measured pace of growth. Challenges related to grid integration and infrastructure gaps became apparent, necessitating strategic interventions for the smooth integration of large-scale solar projects into the national grid.

The analysis of the first three quarters of 2023 reveals intriguing developments, with a continued emphasis on innovation. Emerging trends include floating solar installations and advancements in energy storage technologies. However, regional disparities in installed capacity growth have become more apparent, necessitating targeted interventions for inclusive and equitable development.

In the first three quarters of 2023, the total installed solar PV capacity exceeded 8 GW (rooftop and utility). However, there was a quarter-over-quarter decrease in solar PV installations, with Q1 recording 3.3 GW, followed by 3.2 GW in Q2, and 1.56 GW in Q3.

The country has achieved an installed solar PV capacity of ~72 GW, comprising ~58 GW from utility-scale, 11.08 GW from rooftop installations, and 2.68 GW from off-grid solar.

Various factors influenced quarterly variations in solar PV installed capacity, including pivotal government policies, incentives, subsidies, and regulatory frameworks. Technological advancements, particularly in the efficiency of solar panels and energy storage solutions, played a crucial role in sustaining growth.

Despite the overall positive trajectory, challenges persist, including regulatory uncertainties, delays in project approvals, and infrastructure gaps. Addressing these challenges requires a comprehensive approach involving policy reforms, infrastructure development, and international collaborations.

In conclusion, the quarterly analysis of solar PV installed capacity in India from Q1 2021 to Q3 2023 underscores a dynamic and evolving sector. While significant strides have been made in harnessing solar energy, challenges and opportunities coexist. Collaborative efforts from policymakers, industry stakeholders, and investors are crucial to navigating these complexities and ensuring a sustainable and resilient future for solar energy in India.
