Solar panels absorb the sun's energy throughout the day and convert it into direct current (DC) electricity. Businesses run on alternating current (AC) electricity, so the DC electricity is then passed through an inverter to convert it to usable AC electricity. At that point, you either use the electricity at your business or send it back to the electric grid. The amount of power your solar energy system can generate is dependent on sunlight. As a result, your solar panels will produce slightly less energy when the weather is cloudy, and no energy at night.
