The advantage solar power brings is that peak usage is during the day, which happens to be just exactly when solar power is being produced. So, the coal powered plants don't have to work at as high of an output, and during the night, it still operates normally (in most areas, traditional plants operating at minimal levels (they can't be fully shut down on a nightly basis) produce more than enough electricity to meet night demands). Solar plants, unless combined with a storage mechanism (hydrogen production, batteries, etc.) do not replace traditional power, but instead augments it.
