Answer 1

Correct answer: "Energy from the sun might be greater than the energy needs of the house, so some energy will be stored and/or wasted."

Explanation: The sun can deliver more power than the house needs at times; the excess can be put into batteries or sent to the grid, or simply wasted (curtailed). Energy is conserved — it is not destroyed — but it can be converted to unusable forms (e.g., heat) or unused.
