SOLAR STRATEGIES

India’s solar ambitions have expanded significantly, demonstrated by the recent REINVEST meeting in Gandhinagar, which attracted investment proposals worth USD 386 billion.

The country aims to achieve 570 GW of solar power capacity by 2030, exceeding its global commitment of 500 GW non-fossil fuel capacity.

However, to fully realize its estimated solar potential of 749 GW, India must accelerate its annual capacity additions.

Beyond clean energy, this solar push has strategic and geopolitical implications, as it reduces dependency on imports and strengthens domestic manufacturing through policy initiatives such as production-linked incentives.

    

Significance of Solar Energy Dominance for India

Energy Independence

• Solar energy is key to India’s vision of achieving energy independence, especially as the country imports more than 80% of its oil requirements.
• Solar energy helps reduce this dependency, contributing to India’s goal of 500 GW of non-fossil fuel capacity by 2030, with solar as a major player.
• The REINVEST summit, which attracted USD 386 billion in investment proposals, marks the growing importance of solar energy in securing a stable energy supply.
• Solar energy also provides insulation from the volatility of global oil prices, offering long-term economic stability.

Economic Growth

• The solar sector is becoming a major driver of economic growth in India.
• The solar industry is expected to create 3.26 million jobs by 2050. As of 2021-22, over 29,000 individuals were already employed in this sector.
• The government’s Production Linked Incentive (PLI) scheme, with a budget of ₹24,000 crore, is set to boost solar manufacturing capacity, positioning India as a potential global manufacturing hub.
• This growth not only generates employment but also strengthens India’s manufacturing sector, promoting self-reliance.

Climate Change Mitigation

• Solar power plays a central role in India’s climate change strategies.
• India’s installed solar capacity grew from 2820 MW in 2014 to 72,002 MW in October 2023, marking a 25.54 times increase, making India the fifth-largest solar power producer globally.
• The introduction of India’s Carbon Credit Trading Scheme is expected to further boost solar energy adoption, positioning the country as a leader in global climate action among developing nations.

Rural Electrification

• Solar energy is playing a transformative role in rural electrification across India.
• The Pradhan Mantri Kisan Urja Suraksha evam Utthaan Mahabhiyan (PM-KUSUM) scheme aims to add 30.8 GW of solar capacity by 2026.
• Initiatives like the Solar Charkha Mission empower rural communities by providing clean energy and supporting local economies, narrowing the urban-rural development gap.

Technological Innovation

• India is making significant strides in solar energy technology.
• Indian scientists have developed carbon-based perovskite solar cells that are low-cost and highly stable.
• The National Institute of Solar Energy (NISE) focuses on research and development, contributing to innovations that drive down costs and enhance efficiency.
• In 2022, the cost of solar cells and modules fell by 65% and 50% respectively, making solar power increasingly competitive.

Major Challenges in India’s Solar Sector

Land Acquisition

• Land acquisition for large-scale solar projects remains a significant challenge.
• Solar power plants require about 5 acres per MW of output. India’s target of 500 GW of renewable energy by 2030 could demand over 1.5 million acres, which often conflicts with agricultural and residential needs.
• For instance, the 5000 MW Dholera Solar Park in Gujarat faced opposition from farmers, leading to delays.
• The complexity of India’s land ownership laws further complicates the issue.

Grid Integration

• India’s grid infrastructure, designed for conventional power sources, struggles to handle the variability of solar power generation.
• Transmission losses in India are about 16.4%, much higher than the global average.
• Grid failures, such as the 2020 Mumbai blackout, reveal the vulnerabilities in the current system.

Financing and Investments

• While there has been an influx of investment proposals, securing consistent financing for solar projects is a challenge.
• As of May 2023, electricity discoms owed ₹93,000 crore, causing liquidity issues and raising risks for investors.
• Although green bonds are emerging, with India’s first sovereign green bonds raising ₹16,000 crore, scaling up these mechanisms is necessary to meet the sector’s demands.

Manufacturing Gaps

• India’s solar sector heavily depends on imports, particularly from China, for critical components.
• Despite the introduction of import duties and the PLI scheme, the domestic manufacturing capacity for key inputs like wafers and ingots remains insufficient.
• The global price of polysilicon surged sixfold between 2020 and 2021, highlighting India’s vulnerability to supply chain disruptions.

Storage and Round-the-Clock Power

• India’s limited energy storage capacity hinders the solar sector’s full potential.
• Current battery storage capacity stands at 20 MWh, far below the projected requirement of 74 gigawatts by 2032.
• The high cost of storage makes 24/7 solar power economically challenging.

Environmental and Social Impacts

• Large-scale solar installations can cause habitat destruction and biodiversity loss.
• The Bhadla Solar Park in Rajasthan, one of the largest globally, has raised concerns about its impact on local ecosystems.
• Additionally, the lack of recycling policies for solar panels could result in significant waste generation by 2030.

Steps to Improve India’s Solar Sector

Streamlined Land Acquisition

• A centralized land bank system should be implemented to identify and clear non-agricultural lands for solar projects.
• Agrivoltaics, which allows for dual-use land (agriculture and solar), should be incentivized to address land use conflicts.
• The use of brownfield sites, such as abandoned mines, can be promoted for solar installations.

Grid Modernization

• India must invest in smart grid technologies to manage the variability of solar energy.
• Upgrading transmission infrastructure, with a focus on high-capacity interstate lines for renewable energy, is crucial.
• The deployment of microgrids and distributed energy systems should be incentivized to reduce transmission losses.

Innovative Financing Solutions

• A dedicated Green Bank can offer low-interest loans and risk mitigation tools for renewable energy projects.
• Solar-specific green bonds can attract international investments, tapping into sustainable finance markets.

Domestic Manufacturing

• India should establish joint ventures with global leaders to improve its solar manufacturing capabilities.
• The entire solar value chain, from polysilicon production to module manufacturing, should be strengthened.
• Increased R&D funding for next-generation solar technologies will help bridge the manufacturing gap.

Energy Storage Solutions

• A national energy storage mission with incentives for different storage technologies should be developed.
• Regulatory frameworks should recognize and reward the role of storage in grid stabilization.

Skill Development

• Skill development programs for solar technology should be established, particularly in rural areas.
• Solar technology courses should be integrated into technical institutions, creating a workforce for future solar projects.

Water-Efficient Practices

• Robotic dry-cleaning systems for solar panels in water-stressed areas should be mandated.
• Research into water-saving technologies for solar cleaning must be prioritized.

Conclusion

India’s solar goals are not just about energy independence—they are a path to economic growth, climate action, and technological innovation.

By addressing challenges such as land acquisition, grid modernization, and financing, India can unlock the full potential of its solar sector and establish itself as a global leader in renewable energy.

A comprehensive, sustainable approach is necessary to ensure the long-term success of India’s solar energy ambitions.
