					</table><a href="https://www.mercomindia.com/maharashtra-tamil-nadu-karnataka-lead-q1-solar-open-access-installations" target="_blank" rel="noopener">India added 1.1 GW of solar open access capacity in the first quarter (Q1) of 2025, down nearly 48% from 2.1 GW in Q4 2024</a>. Installations were down 47% year-over-year (YoY) from over 2 GW, according to the Q1 2025 Mercom India Solar Open Access Market report. Domestic solar modules were scarce due to the rush to commission before the end of the financial year. The quarter saw a slowdown in the commissioning of solar open access projects due to a shortage of transmission infrastructure, delays in the clearance procedure for connectivity, and uncertainty regarding the interstate transmission system (ISTS) waiver.
<a href="https://www.mercomindia.com/indias-solar-exports-up-26-imports-surge-80-2-qoq-in-q1-2025" target="_blank" rel="noopener">Indian solar module and cell exports increased 26.1% quarter-over-quarter (QoQ) to $267.6 million (~₹23.1 billion) in Q1 of 2025</a> from $212.2 million (~₹17.92 billion), according to recent data published by the Department of Commerce. However, module and cell exports declined 59.9% YoY to $666.7 million (~₹55.37 billion). Solar exports in the quarter were dominated by photovoltaic modules, which accounted for 98.7% of the total shipments, while solar cells made up the remaining 1.3%. The U.S. was the primary destination for Indian solar cell and module exports, accounting for 99.5% of the total in Q1 2025.
<a href="https://www.mercomindia.com/vppas-in-india-not-gained-momentum-cerc-guidelines" target="_blank" rel="noopener">Virtual power purchase agreements (VPPAs), a financial tool for energy-intensive industries seeking to meet their renewable energy obligations</a>, have not gained momentum in India despite their seemingly promising nature. The Central Electricity Regulatory Commission recently released draft guidelines to enable designated consumers to meet their renewable commitments. Under these guidelines, a VPPA or a designated consumer may enter into long-term bilateral virtual agreements with a renewable energy generator at an agreed-upon price.

<a href="https://www.mercomindia.com/monsoon-winds-weak-links-rooftop-solar" target="_blank" rel="noopener">As solar systems proliferate on India’s rooftops, a silent crisis is unfolding. The promise of clean energy and cost savings is being increasingly undercut</a> by poor engineering practices and subpar installations, many of which cannot withstand the monsoon winds and cyclonic conditions common in several parts of the country. Recent weather incidents in cities like Bhilwara, Gwalior, Indore, Mira Road, Kanpur, and Lucknow have highlighted this issue.
<a href="https://www.mercomindia.com/average-cost-of-large-scale-solar-projects-rose-marginally-in-q1-2025" target="_blank" rel="noopener">Large-scale solar project costs in India increased for the second consecutive quarter, according to Mercom’s Q1 2025 India Solar Market Update</a>. Average project costs rose 3% QoQ and 1% YoY. The average selling price of Indian-made DCR-compliant modules increased in Q1 2025, fueled by strong demand from government programs like PM Surya Ghar and PM KUSUM and rising component costs. With developers scrambling to secure limited production slots, pricing pressure increased further.
<a href="https://www.mercomindia.com/solar-open-access-capacity-additions-in-india-slump-48-qoq-in-q1" target="_blank" rel="noopener">India’s solar open access capacity additions dropped 47% YoY to 1.1 GW in the Q1 of 2025 from over 2 GW</a>, according to Mercom India’s Q1 2025 Solar Open Access Market Report. Solar open access capacity additions also dropped 48% QoQ from 2.1 GW in Q4 2024. According to Priya Sanjay, Managing Director of Mercom India, the numbers appear down, especially since the comparative quarters recorded high-capacity additions last year due to different reasons.

					</table>The Central Pollution Control Board (<a href="https://cpcb.nic.in/" target="_blank" rel="noopener">CPCB</a>) has issued draft guidelines for the collection and storage of waste from solar modules and cells.
Stakeholders can submit comments and suggestions to CPCB by June 25, 2025.
Solar waste refers to end-of-life solar modules or cells that are discarded whole or in part as waste. It includes rejects and waste generated during manufacturing, refurbishment, and repair processes.  It also covers solar modules that were damaged during transportation, handling, storage, and installation.
Under the E-Waste (Management) Rules, 2022, solar waste is categorized as electrical and electronic equipment waste. The rules place the onus of managing solar waste on the manufacturers of solar components. Manufacturers must store solar waste up to the end of the financial year 2035.
Collection
Manufacturers of solar cells and modules must devise a collection mechanism to collect waste from both individual and bulk consumers. They must publicize details about the collection points for solar waste or any take-back programs available.
Transportation of solar waste must be done in covered trucks and preferably in trucks authorized for the transportation of hazardous waste.
According to the CPCB, solar waste must not be disposed of or dumped in open areas, as it could release toxic chemicals into the environment. The solar waste must not be sold to unauthorised entities.
Storage
The solar waste must be stored safely to prevent breakage of the waste. It must be kept away from sharp objects that could damage the modules.
The storage facility must have at least 19.5 m3/ton of space.
Storage of solar waste must be carried out in a manner that allows for reuse after refurbishment, recycling, or recovery of materials.
The solar modules must be stored in a covered, dry, and ventilated area.
Storage racks or containers used for storing solar waste must be clearly labeled, indicating the type of waste they contain, to facilitate identification and sorting during recycling processes.
The stored solar waste must be periodically inspected and recorded to check for any damage.
The floor of the storage facility must be non-leachable, considering the leaching potentials of metals from solar waste such as antimony, cadmium, arsenic, lead, and selenium.
Solar modules that are part of solar waste must not be stacked in more than 20 layers or to a maximum height of 2 m above the ground.
The storage facility must be equipped with a fire protection system with adequate firefighting arrangements, an escape route for emergency exit, and an emergency response plan.
In December 2024, in response to a letter petition from a resident of Sapai village, Kanpur, Uttar Pradesh, the National Green Tribunal <a href="https://www.mercomindia.com/green-tribunal-seeks-government-response-on-disposal-of-used-solar-modules" target="_blank" rel="noopener">sought</a> responses from multiple government agencies on a plea regarding the improper disposal and recycling of photovoltaic solar modules.
In May 2025, the Gujarat Energy Development Agency <a href="https://www.mercomindia.com/gujarat-invites-eoi-for-study-on-material-recovery-from-solar-e-waste" target="_blank" rel="noopener">invited</a> expressions of interest for a research study to recover valuable materials from solar and electronic waste. The project aims to assess the feasibility of material recovery methods and develop an implementation roadmap to aid Gujarat’s renewable energy and waste management sectors.
