It is too simple. If everyone had solar panels the power companies would go broke, unless they jacked up their connection fees. But, that would unfairly impact people who can't afford to put solar panes on their roofs. It would be better if power companies bought the power from homeowners at wholesale costs during peak production hours and sold them power at normal retail prices when the sun is down. Net-metering, like the system you describe, is codified in many state's laws, including Hawaii, but I don't think it will be sustainable as solar panels become more common.
