look I reviewed you post history. I believe you are honest in asking this question.
I assume you post is in good faith, but it's not clear what you mean or how you want your question to be answered.

Solar energy is harvested whenever the sun is out.
Plants use that energy to create energy dense sugars.
What's exactly are you asking?
