Solar manufacturing growth, seaweed biomethane contract, and Tunisian storage tenders
India's list of qualified solar cell makers grew to roughly 37.8 GW after adding 402 MW of annual capacity from Gopin Semicon's Gujarat site, which produces n-type TOPCon cells. SmartestEnergy will purchase renewable gas from Zenco Group's planned seaweed-based digestion plant, which is designed to yield as much as 420 GWh of biomethane each year starting in 2028. Tunisia's state utility STEG has begun tenders for a 50 MW solar farm with battery storage in Tataouine and a separate 300 MW/600 MWh battery scheme.
India's approved cell capacity under ALMM List-II now stands near 37.8 GW. The October 8, 2026 update added 402 MW from Gopin Semicon's Gujarat plant, which makes n-type TOPCon cells averaging 25.57% efficiency. The framework began in July 2025; approved module capacity under List-I is about 225.5 GW.
SmartestEnergy's long-term deal with Zenco Group covers biomethane from a planned seaweed-fed anaerobic digestion facility. Output may reach 420 GWh yearly, with operations targeted for 2028. Phase one feeds the UK gas network; phase two adds renewable fuel. STEG's tenders cover Tataouine solar-plus-storage and a 300 MW/600 MWh battery program.
These moves could affect solar developers and manufacturers in India by widening approved supply options. UK gas users and related supply chains may see more renewable gas if the seaweed project proceeds. Tunisian electricity customers and grid operators may benefit from added storage and solar capacity, though outcomes depend on tender execution, costs, and grid integration.
