Runergy vs Solarspace - solar panel manufacturer comparison
Runergy has the broader catalog (124 vs 82 models). Runergy leads on peak efficiency at 24.10%. Solarspace leans bifacial (93% of lineup).
Both catalogues are read from the manufacturers' own datasheets. A brand is not scored against the market here, only against the other brand on this page.

Catalogue against catalogue
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
I have enough sourced information now.
Runergy is a Chinese solar manufacturer headquartered in Jiangsu, with additional production facilities in Thailand, Vietnam and the United States. It has been recognized by BloombergNEF as a Tier 1 PV module manufacturer for six consecutive quarters through Q1 2025, and by the end of 2023 the company had shipped over 65 GW of solar cells, indicating substantial upstream cell-manufacturing scale. Solarspace has also appeared on BNEF's Tier 1 list, rejoining it in Q2 2024 after a prior absence, and operates six manufacturing bases across Cambodia, Laos and China with a global sales network spanning the Americas, Europe, Asia, Australia and the Middle East. Runergy's longer, uninterrupted Tier 1 streak and its large cell-shipment volume suggest a somewhat stronger and more consistent institutional footprint than Solarspace, whose Tier 1 status has been less continuous.
Both brands center their product lines on n-type TOPCon technology. Runergy markets bifacial dual-glass TOPCon modules such as the HY-DH144N8 for utility-scale ground-mount projects, alongside all-black TOPCon modules like the HY-DH108N8B aimed at residential and commercial rooftops; its latest TOPCon 3.0 cells have reached certified efficiencies above 26 percent, verified by Fraunhofer ISE. Solarspace's panels span a wide power range, roughly 400 to 720 watts, with efficiencies cited between 20 and 23 percent, positioning the brand in the medium price segment and covering both rooftop and larger installations; its modules have also received independent testing endorsements from RETC and PVEL. Solarspace's warranty terms are reported as relatively short, around 12 to 15 years, which buyers should weigh against typical industry norms of 25 to 30 years.
For a typical 2025 buyer prioritizing bankability and continuous Tier 1 standing, Runergy currently presents the stronger default choice, backed by its longer unbroken BNEF streak and high-efficiency TOPCon 3.0 technology. Solarspace remains a credible Tier 1 alternative, particularly where its RETC/PVEL-tested products and wide power range fit the project, but its shorter warranty and less continuous Tier 1 history warrant closer due diligence.
