There exist sophisticated electronic load balancing systems that handle these sort of power management functions. In essence, they can bring in power from whatever source is available to meet the demand your home is placing on it. They can even decide which is most efficient, based on solar intensity, current wind speeds, etc. If you are in an area with net metering and can sell excess power BACK to the grid, they can handle that, too. They come with a steep price tag still, but they exist. The lowest cost residential systems of this nature that I’ve seen are still over US$10,000.
