Rune builds 1 MW solar-powered data center in Texas with 50 RELIC modules

Startup Rune built a 1 MW data center in Texas using 50 RELIC modules connected directly to a solar farm without new power plants or grid connection. The company raised $40M Series A led by Spark Capital and claims 90% cost reduction per megawatt.

• RELIC modules use DC power directly from solar panels, no transformers
• 1 MW data center with 50 modules assembled in one hour using a forklift
• Solar stations lose up to 20% output; California lost 3.5M MWh in 2025
• Rune plans to deploy 100 MW on solar farms in a year
