Solar Deployment, Markets and Policy
August brought significant solar deployment developments across major global markets, combining record capacity additions with new policy frameworks and expanding residential applications. From India and Europe to Egypt, these developments highlight the growing scale and diversity of global photovoltaic deployment.
1. India Adds a Record 27 GW of Solar Capacity
India installed a record 27 GW of solar capacity during the first half of 2026, representing a 50% increase from 18 GW in the same period of 2025. Solar accounted for 76% of all new power capacity added during the period, while India's cumulative installed PV capacity reached approximately 165 GW by the end of June.
2. India's Rooftop Solar Installations Reach 6.6 GW
India also recorded exceptional growth in distributed solar, installing 6.6 GW of rooftop PV during the first half of 2026, up 136% year-on-year. Residential systems dominated the market, supported by the PM Surya Ghar program, while rooftop solar accounted for around one-third of India's total solar installations during the second quarter.
3. Italy Allocates 10 GW of PV Under New FerX Scheme
Italy finalized its new FerX renewable energy support mechanism with a 10 GW allocation for photovoltaic projects. The scheme establishes a reference strike price of €80/MWh and provides additional incentives for selected applications, including floating PV installations and solar systems replacing asbestos roofing, strengthening Italy's framework for continued solar deployment.
4. Egypt Completes 1.1 GW Obelisk Solar-Plus-Storage Project
Egypt reached a major renewable energy milestone with completion of the 1.1 GW Obelisk solar project near Nagaa Hammadi in Upper Egypt. Developed by Scatec, the $590 million facility combines photovoltaic generation with a 100 MW/200 MWh battery energy storage system and is expected to generate more than 3,000 GWh of clean electricity annually.
5. Plug-In Solar Opens a New Residential Market in Britain
British households are set to gain access to plug-in solar systems, allowing smaller photovoltaic installations to connect directly to domestic electrical systems under a new regulatory framework. The approach could expand solar access for renters, apartment residents, and households unable to install conventional rooftop arrays, extending distributed generation to a broader residential market.

Solar Manufacturing and Industry Expansion
August highlighted major shifts across the solar manufacturing industry, with new factories, expanding production capacity, and deeper supply-chain integration across several markets. At the same time, persistent financial pressure in China showed the challenges created by intense competition and global PV oversupply.
6. Egypt Plans a $1 Billion Integrated Solar Manufacturing Complex
Egypt is considering a major $1 billion solar manufacturing complex in Zafarana designed to integrate several stages of the photovoltaic supply chain. The proposed project would use domestic quartz resources to support production through to finished solar panels, strengthening local manufacturing while reducing dependence on imported PV components.
7. SEG Solar Opens a 4 GW Module Factory in Texas
SEG Solar opened a new 4 GW photovoltaic module manufacturing facility in Texas as part of its expanding U.S. production strategy. The company also announced plans that could increase its total U.S. module assembly capacity to 10.6 GW by 2027, reflecting continued investment in domestic solar manufacturing.
8. Türkiye's PV Module Manufacturing Capacity Exceeds 13 GW
Türkiye's operational PV module manufacturing capacity has climbed to approximately 13.4 GW, strengthening the country's position within the international solar supply chain. The expansion reflects continued investment in domestic photovoltaic manufacturing as countries increasingly seek greater local production capacity and reduced dependence on imported solar equipment.
9. China's Major Solar Manufacturers Continue to Report Losses
Several leading Chinese photovoltaic manufacturers reported continued financial losses during the first half of 2026. Longi, TCL Zhonghuan, GCL Technology, Daqo New Energy, and Xinte Energy remained under pressure as manufacturing overcapacity, intense competition, and weak product prices continued to challenge profitability across China's enormous solar industry.
10. SLR Solar Expands TOPCon Manufacturing and Plans Further Integration
India's SLR Solar secured approval for 1.02 GW of TOPCon module capacity while outlining plans to expand further into solar cell and battery energy storage manufacturing. The strategy illustrates a broader industry trend toward vertically integrated production as manufacturers seek greater control over technology, supply chains, and future market opportunities.

Solar Technology and Next-Generation PV
Solar innovation continued beyond conventional silicon modules during August, with advances in next-generation PV efficiency, large-area perovskite technology, and stronger modules designed for harsh environments. These developments show how research is increasingly moving toward commercially scalable, durable, and higher-performance photovoltaic systems.
11. Tandem PV Reaches 30.4% Module Efficiency
Tandem PV reported a 30.4% efficiency for its perovskite-silicon tandem module as the company moves toward initial commercial sales later in 2026. The technology combines perovskite and silicon photovoltaic layers to capture a broader portion of the solar spectrum, potentially delivering substantially higher conversion efficiencies than conventional single-junction silicon modules.
12. Large-Area Perovskite Modules Achieve 24% Efficiency
Chinese researchers reported a certified 24.0% efficiency for an 810 cm² perovskite solar module, alongside 22.0% efficiency for a larger 0.72 m² module. The results are significant because maintaining high efficiency as perovskite devices increase in area remains one of the major challenges facing the technology's transition from laboratory cells toward commercial-scale modules.
13. Trina Solar Develops Typhoon-Resistant PV Modules
Trina Solar introduced photovoltaic modules and mounting solutions engineered for severe wind conditions, with modules designed to withstand mechanical loads exceeding 8,000 Pa. The development targets typhoon-prone regions where extreme winds can impose substantial structural loads on PV systems, making mechanical durability increasingly important as solar deployment expands into challenging environments.
