The company has expanded its production footprint significantly, with operational capacity across facilities in Zhuhai and Yiwu, and plans to ship more than 20 GW of modules annually in the near term. BYD is a Chinese industrial conglomerate founded in Shenzhen in 1995, originally as a battery producer; it entered the photovoltaic module business in 2009 and also carries Bloomberg NEF Tier 1 status. BYD operates panel manufacturing plants in China and Brazil, though its dedicated solar production scale is considerably smaller than AIKO's, reflecting that solar remains one division within a much larger enterprise. On institutional footprint and technology focus, AIKO carries more weight as a pure-play solar specialist. AIKO's product lineup is built almost entirely on ABC technology, delivering module efficiencies that comfortably exceed those of conventional TOPCon competitors, with the Neostar series reaching confirmed figures above 24 percent. That performance comes at a price premium of roughly 20 to 30 percent over mid-tier Chinese brands, making AIKO most compelling for constrained residential rooftops where every square meter counts. BYD's panel range spans from around 395 W to 650 W, targeting both residential and commercial-scale projects. Its module efficiencies are competitive but more modest, and its 12-year product warranty is notably shorter than the 25-year product warranty AIKO offers, even though BYD's performance guarantee runs to 30 years. For a buyer in 2025 with limited roof space and a long investment horizon, AIKO's higher efficiency and stronger product warranty make it the more defensible choice despite the cost premium. BYD suits buyers who prioritize a lower upfront price and are comfortable with the trade-offs on warranty depth and efficiency ceiling. The two brands are not interchangeable - they occupy distinct positions on the performance-versus-cost spectrum. \---LINKS--- \- https://www.pv-tech.org/aiko-capacity-upgrades-abc-cell-technology/ \| Aiko steps up ABC transition with 11GW capacity upgrade \| article \- https://www.pv-magazine.com/2025/01/10/chinese-pv-industry-brief-aiko-solar-starts-making-back-contact-pv-panels/ \| Aiko Solar starts making back contact PV panels - PV Magazine \| article \- https://www.solarquotes.com.au/panels/aiko-solar-review.html \| Aiko Solar panels review - SolarQuotes \| review \- https://www.solarquotes.com.au/panels/byd-solar-review.html \| BYD Solar panels review - SolarQuotes \| review \- https://www.solarchoice.net.au/products/panels/byd-solar-panel-review/ \| BYD Solar Panels - Independent Review by Solar Choice \| review Sources: \- \[Aiko steps up ABC transition with 11GW capacity upgrade - PV Tech\](https://www.pv-tech.org/aiko-capacity-upgrades-abc-cell-technology/) \- \[Aiko Solar starts making back contact PV panels - PV Magazine\](https://www.pv-magazine.com/2025/01/10/chinese-pv-industry-brief-aiko-solar-starts-making-back-contact-pv-panels/) \- \[Aiko Solar panels review - SolarQuotes\](https://www.solarquotes.com.au/panels/aiko-solar-review.html) \- \[BYD Solar panels review - SolarQuotes\](https://www.solarquotes.com.au/panels/byd-solar-review.html) \- \[BYD Solar Panels - Independent Review by Solar Choice\](https://www.solarchoice.net.au/products/panels/byd-solar-panel-review/) Written by claude-sonnet from the figures above. ## Other comparisons - [AIKO vs A.B.
