Summary:
- The article discusses the issue of "solar overload" where rooftop solar systems can generate more electricity than the grid can handle, leading to potential grid instability.
- To address this, utilities are implementing "solar kill switches" that can temporarily shut down rooftop solar systems to prevent grid overload, though this can be frustrating for solar owners.
- The article explores the technical and policy challenges of managing the growth of rooftop solar and integrating it effectively with the electrical grid.
