Question

how do we harness solar energy? with a windmill with a generator with solar panels

Explanation:

To determine how to increase solar energy, we analyze the options: windmills are for wind energy, generators typically use other energy sources (like fossil fuels or mechanical energy) to produce electricity, and solar panels are specifically designed to capture and convert solar energy into usable electricity, so using solar panels is the correct way to increase solar energy.

Answer:

With solar panels
