Increase in solar PV module price to moderate returns for solar projects developers: ICRA

  • This risk is especially significant for the capacity won by developers through the bidding route over the last 6-9 months at tariffs ranging between Rs 2.00-2.25 per unit
  • The solar bid tariff, after factoring in this dual impact (of BCD and rise in module prices), is still likely to remain below Rs 3/unit

New Delhi: The increase in imported photovoltaic (PV) solar module price level by about 15-20 percent over the last four-five months, to around 22-23 cents/watt, as on date, is likely to impact returns of solar power project developers. This price rise has been mainly driven by a sharp increase in the price of polysilicon, a key input for cell and module manufacturers. In a report published on Wednesday, ICRA said that given the import dependency for PV modules for a majority of the solar power installations in India, such hardening in the price of PV modules, if sustained, remains a near-term headwind. 

This risk is especially significant for the capacity won by developers through the bidding route over the last six to nine months (amounting to 4-GW) at tariffs ranging largely between Rs 2.00 per unit and 2.25 per unit, and the projects that are scheduled to be commissioned over the next 12-15-month period. This apart, the recent surge in metal prices is also leading to upward pressure on the overall capital cost for solar power projects.

BCD, module price increase to raise solar power tariff by 55-60 paise/unit

Commenting further, Girishkumar Kadam, Senior Vice President and Co-Group Head- Corporate ratings, ICRA, said, “Given that the solar PV module component comprises about 50-55 percent of the overall project cost, such increase in the module price level by about 4-5 cents/watt if sustained, is likely to moderate the debt service coverage metrics for the project developers by about 12-14 basis points. Alternatively, the tariff increase required to offset such a module price increase is estimated at about 20-22 paise/unit. This, along with the impact of the basic customs duty (BCD) on imported PV modules, is likely to result in the overall bid tariff to increase by about 55-60 paise/unit for the forthcoming auctions. Nonetheless, the solar bid tariff, after factoring in this dual impact, is still likely to remain below Rs 3/unit.”

As the BCD notification for cells and modules is effective from April 2022 onwards, there remains a possibility for a surge in demand for imported modules, particularly in the fourth quarter of the current fiscal in turn, supporting the elevated price levels for PV modules. In this context, both the module price behaviour and honouring of supply contracts by module OEMs from China in the near term continue to remain key monitorables for the solar power developers, said ICRA. 

Challenges ahead for solar power project developers

Further, the registration of module manufacturers outside India, in the Approved List of Models and Manufacturers (ALMM) issued by the Ministry of New and Renewable Energy (MNRE) in March 2021, remained affected due to the lockdown restrictions and procedural requirements so far, based on industry sources, said the report.


1. IREDA invites bids from module manufacturers under Rs 4,500-crore Solar PLI scheme

2. NDMC will procure 150 MW of solar power from SJVN’s CPSU scheme projects

As per the notification issued by the MNRE, the projects bid out under the standard-bidding guidelines, post April 10, 2021, are required to procure modules from the approved list. This, in turn, may pose near-term challenges for Indian developers for planning the procurement of imported PV modules, especially given the capacity constraints for domestic manufacturers.

Credit outlook on solar energy sector stable: ICRA

Vikram V, Vice President and Sector Head, Corporate Ratings, ICRA, said, “As a result, the uncertainty on the timelines for inclusion of module suppliers from China in the ALMM list may affect the incremental bidding activity in the solar power sector. Nonetheless, cumulative solar project awards as of date remain strong at ~28 GW (excluding the capacity pending for signing of PSA/PPAs and including hybrid projects), which provides healthy visibility on the capacity addition over the medium term.”

Notwithstanding the near-term headwind related to module price levels, the credit outlook on the solar energy sector remains stable, given the improved tariff competitiveness, supportive regulatory framework through must-run status for these plants, leading to satisfactory operating track record, as well as the availability of liquidity buffer (which is mix of debt service reserve account and access to working capital limits) for the issuers rated.
