Solar Storm Warning: Installers Should Spare A Thought For EMP ...: Severe solar storms may result in terrestr...

In July of this year, a massive solar flare narrowly missed the Earth, and thus, we dodged the resulting electromagnetic pulse (EMP) that could have caused worldwide power outages. In the words of one nuclear weapons expert , the world escaped an EMP catastrophe. Severe solar storms may result in terrestrial geomagnetic storms that could cause power loss on a global basis for an extended period due to DC-like currents in unprotected large, AC high-voltage transformers. Basic solar panel installations are resistant to the severe solar storm threat because an EMP is only a threat to equipment such as the large transformers at central generating stations and substations. Distributed power systems, such as grid-interconnected solar, could keep the local power grid partially operational during a severe solar storm as long as sufficient solar power is available to the grid.
