1. What is Energy Consumption Calculation?

The energy consumption calculation determines how much electrical energy a solar panel system produces or consumes over time. It's measured in kilowatt-hours (kWh), which is the standard unit for electricity billing.

2. How Does the Calculator Work?

The calculator uses the energy formula:

Where:

• \( kWh \) — Energy in kilowatt-hours
• \( P \) — Power in watts (W)
• \( h \) — Time in hours

Explanation: The formula converts watt-hours to kilowatt-hours by dividing by 1000 (since 1 kilowatt = 1000 watts).

3. Importance of Energy Calculation

Details: Calculating energy consumption helps in sizing solar panel systems, estimating electricity costs, and understanding energy production potential.

4. Using the Calculator

Tips: Enter the power rating of your solar panel in watts and the number of hours it operates. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between watts and kilowatt-hours?
A: Watts measure power (instantaneous energy rate), while kilowatt-hours measure energy (power × time).

Q2: How can I estimate daily solar production?
A: Multiply panel wattage by peak sun hours in your location (typically 3-6 hours/day).

Q3: Why divide by 1000 in the formula?
A: To convert from watt-hours (Wh) to kilowatt-hours (kWh), the standard unit for electricity billing.

Q4: How accurate is this calculation?
A: It provides theoretical maximum. Actual production depends on panel efficiency, sunlight angle, temperature, and system losses.

Q5: Can I use this for battery sizing?
A: Yes, knowing your daily kWh needs helps determine battery capacity requirements.
