Let's break down the problem step by step.

Given Information:

• Solar power generated: 1.6 kW for 3.0 hours.
• Power usage during the same period: 2.2 kWh.

Step 1: Calculate Solar Energy Produced

The energy produced by the solar panels is given by the formula: $\text{Energy} = \text{Power} \times \text{Time}$ Using the values provided: $\text{Energy produced} = 1.6 \, \text{kW} \times 3.0 \, \text{h} = 4.8 \, \text{kWh}$

Step 2: Compare with Power Used

The total energy used during the period is 2.2 kWh. Since more energy is produced (4.8 kWh) than used (2.2 kWh), the meter will run backward.

Step 3: Calculate the Change in Meter Reading

The change in the meter reading will be the difference between the energy produced and the energy used: $\text{Change in meter reading} = \text{Energy produced} - \text{Energy used}$ $\text{Change in meter reading} = 4.8 \, \text{kWh} - 2.2 \, \text{kWh} = 2.6 \, \text{kWh}$

Final Answer:

The change in the meter reading will be 2.6 kWh (rounded to the nearest tenth).
