That's true during the hotter months, but that's a benefit of why renewable energy comes from different sources. When it's not very sunny, it may be windy, the tide might be changing, the rivers are still flowing, the ground is still warm. The same applies to nuclear, or when there's a shortage of oil or coal. You can't run one generator at full output, so you can increase the output of another.
