Renewable energy platform company H Energy said it has cut the time from detecting abnormalities in solar power systems to taking action to as little as 4 hours using its AI-based solar power plant asset management platform, SolarOnCare. H Energy said on April 9 it will unveil the technology at the 2026 International Green Energy Expo in Daegu EXCO from April 22 to 24. The company said it currently operates and maintains 5,739 solar power plants nationwide totaling 712.9 MW, and will present indicators based on that operating data at the expo.

SolarOnCare identifies abnormal plants by grouping and comparing power plants with similar weather and equipment conditions. It said AI analyses panel current and voltage curves to classify 5 fault types with 90.9 percent accuracy, then combines fault history and weather data to estimate causes remotely and automatically draw up an action plan.

As the AI system runs the full process from anomaly detection to action plan creation, fault response time has been shortened from a previous average of 10.58 days to 4.18 hours. SolarOnCare-managed plants average 3.93 hours of daily power generation time, 17 percent above the market average of 3.3 to 3.5 hours. It has adopted a SaaS structure in which operating staff do not increase in proportion even as the number of plants grows.

H Energy said it will also run events for on-site experts during the expo. It will hold a partners meeting on April 22 and a conference for safety managers, DERlink, on April 23. DERlink is a safety manager conference being held for the first time this year, where solar and ESS safety managers nationwide will share on-site practical know-how and present operating cases using SolarOnCare. An H Energy official said, "We will connect safety managers, who are on-site experts, as key partners in the SolarOnCare platform ecosystem and continue to support them to strengthen competitiveness."

Chief Executive Ilhan Ham (함일한) said, "Solar power plants are long-term assets that must be operated for 20 years, but Korea does not have a systematic operations and maintenance market," adding, "SolarOnCare will help create an AI-based asset management standard."
