Weekly Solar Industry Insights: February 17th – February 23rd, 2025

U.S. Solar Industry Adds Nearly 50 GW of New Capacity in 2024

The U.S. solar industry added nearly 50 GW of new capacity in 2024, including 39.6 GW of utility-scale and almost 10 GW of rooftop solar. Despite challenges, like supply chain issues and rising costs, solar remains cost-effective, with Texas leading in new installations. The year also saw increased solar cell imports and investments in reshoring renewable energy production, though concerns about manufacturing and interconnection backlogs persist.

U.S. EPA Seeks Immediate Termination of $20 Billion in Clean Energy Grants

The U.S. EPA plans to terminate $20 billion in clean energy grants from the Biden Administration’s Greenhouse Gas Reduction Fund (GGRF), citing concerns over transparency and oversight. The GGRF, part of the Inflation Reduction Act, funds clean technology, solar energy for low-income households, and projects in disadvantaged communities. The decision has sparked controversy and legal disputes, with some defending the grants' transparency and economic benefits.

Trump Reinstates 25% Tariffs on Imported Steel and Aluminum, Impacting Solar Industry

On February 17, 2025, President Trump reinstated 25% tariffs on imported steel and aluminum, which will impact the solar industry. These materials are essential for solar panel frames, rooftops, and ground mounts. The tariffs are intended to boost domestic production but are expected to raise costs for residential and utility-scale solar projects. Aluminum alone accounts for 14% of solar panel production costs, making the tariff increase significant for the industry.

Global Solar Generation Surges by 30% in 2024, Exceeding 2,000 TWh

Electricity 2025 report reveals that global solar generation grew by 30% in 2024, reaching over 2,000 TWh for the first time. Solar accounted for 7% of global electricity generation, up from 5% in 2023, and is expected to meet half of the global electricity demand growth by 2027. This surge is getting driven by policy support, cost reductions, and significant contributions from China. The report also notes that solar surpassed coal in the EU’s energy mix and forecasts further growth in China, the USA, and India.

Polysilicon Market Holds Steady Amid Policy Uncertainty

The global polysilicon market remains stable at $20.360/kg. While Chinese exports surged by 46%, especially to Malaysia, U.S. trade policies, including potential tariffs on solar imports, may impact prices. Chinese production is steady but hampered by high electricity costs, and efforts are underway to address market oversupply.

Indian Scientists Design 31.16%-Efficient 2D-3D Perovskite Solar Cell

Indian scientists have developed a 2D-3D perovskite solar cell with a simulated efficiency of 31.16%. Combining a Dion-Jacobson (DJ) 2D layer with a 3D lead-free halide perovskite, the design enhances stability over traditional perovskite cells. The optimal configuration includes a 2D PeDAMA4Pb5I16 layer and a 3D CsGeI3-xBrx layer, using silver contacts and a cuprous oxide hole transport layer, making this innovation a promising solution for future solar applications.

Solar Module Capacity Under ALMM Drops to 67.1 GW

India's solar module manufacturing capacity under the Approved List of Module Manufacturers (ALMM) has decreased to 67.1 GW due to expired registrations, however, two new manufacturers were added, bringing the total to 92. ALMM continues supporting domestic solar growth, with plans to include solar cells by June 2026.

Rajasthan Increases Free Electricity Units with Rooftop Solar Projects

The Rajasthan government has increased free electricity units from 100 to 150 under the Chief Minister Free Electricity Program. This initiative, part of the PM Surya Ghar: Muft Bijli Yojana, provides free rooftop solar systems to eligible households. Community rooftop solar projects will also benefit low-income groups without rooftop access. The state aims to install 10 GW of renewable energy and expand agricultural and domestic electricity connections.
