An average over a catalogue describes the range a manufacturer publishes, not the module you would buy. A brand with two flagship panels and eighty older ones averages worse than one that has retired its back catalogue.

Written summary

LONGi Solar, formally LONGi Green Energy Technology Co., Ltd., is a Chinese solar manufacturer headquartered in Xi'an, founded in 2000. It ranks among the world's largest PV module producers by shipment volume - in the first nine months of 2025 the company shipped more than 63 GW of cells and modules, representing nearly 24% year-on-year growth. LONGi holds BloombergNEF Tier 1 status consistently and in Q1 2026 was named a BloombergNEF Tier 1 energy storage manufacturer for the first time as well. Waaree Energies is an Indian solar manufacturer founded in 1989 and headquartered in Mumbai, with a long track record in the renewable energy sector. The company has maintained BloombergNEF Tier 1 status for 35 consecutive quarters and in February 2025 became the first Indian PV module manufacturer to receive a ModuleTech Bankability 'A' rating from PV Tech. According to available sources, Waaree operates approximately 22.3 GW of global module manufacturing capacity across facilities in India and the United States, alongside 5.4 GW of solar cell capacity. By global scale and institutional reach, LONGi currently carries the stronger footprint of the two.

LONGi's European product strategy centres on the Hi-MO X10 series, built on its proprietary second-generation back contact technology (HPBC 2.0) and the newer HIBC architecture that pairs heterojunction passivation with a full back-contact structure. Modules in this series target both residential rooftop installations and commercial C&I projects, and have been formally launched in the UK, Benelux, and the Iberian Peninsula. Higher-wattage configurations in the same family address utility-scale ground-mount demand. Waaree's portfolio spans residential, commercial C&I, and utility-scale segments, with recent product efficiency figures cited at up to approximately 22.79-23.5% depending on the series. The company has been predominantly active in India and is expanding US manufacturing; its European push is planned to accelerate from 2026 under the EU Net-Zero Industry Act framework, which may favour non-Chinese suppliers in European procurement.

For buyers evaluating the European or Polish market today, LONGi is the more readily accessible choice, with an established distribution presence and actively rolling out new module generations across the continent. Waaree is a credible, bankable manufacturer - particularly well positioned for Indian and North American project pipelines - and is a brand to watch as its European distribution develops. Buyers with a longer procurement horizon and an interest in supply-chain diversification away from Chinese manufacturers may find Waaree an increasingly compelling alternative in the medium term.
