Challenges for Solar Energy

India faces several key challenges in scaling up solar energy production and integration into the electrical grid. Land acquisition has proven difficult due to competing uses for land as well as administrative issues in acquiring and transferring land titles (https://www.linkedin.com/pulse/what-main-challenges-opportunities-indian-solar-singh-yks-/). Large-scale solar projects require significant land area with optimal sun exposure and proximity to transmission infrastructure. With other demands on land for agriculture, residential use, and industry, available lands may not align well with solar project siting needs.

Integrating solar power into the electrical grid also poses technical challenges. Solar generation varies throughout the day and seasons, so grid operators must balance this fluctuating supply with other generation sources. Upgrades to transmission infrastructure are needed in areas with high concentrations of solar farms to handle power flows (https://www.eai.in/ref/ae/sol/cs/spi/kc/key_challenges_in_the_growth_of_solar_pv_technology_in_india.html).

Cost competitiveness of solar compared to coal and other power sources has also been a barrier. However, costs have declined dramatically, and solar is now cheaper than coal in many cases. But further cost reductions through research, manufacturing improvements, and scale will be important for continued growth (https://enphase.com/en-in/blog/homeowners/solar-experience/indias-solar-energy-sector-challenges-opportunities-and-way/).


As noted in earlier sections, Rajasthan is currently the largest producer of solar energy in India. The state accounts for almost 25% of the country’s solar energy capacity, thanks to abundant land availability and high solar irradiance. With over 7,500 MW of solar power generation capacity, Rajasthan is significantly ahead of other leading solar states like Gujarat, Madhya Pradesh, Andhra Pradesh, and Karnataka.

The future outlook for solar energy in India is quite positive. The government aims to achieve 100 GW of solar capacity by 2022 as part of the country’s renewable energy goals. To meet this target, solar energy generation will need to grow rapidly not just in Rajasthan but across all states. Rajasthan is expected to maintain its dominance, given its natural advantage and proactive policies. But other states are also ramping up solar parks and facilities and could emerge as major contributors. Overall, solar power is poised to become a vital part of India’s renewable energy mix and reduce the dependence on fossil fuels.
