1. What is a Solar System Usage Calculator for Home?

Definition: This calculator estimates the energy consumption of home appliances in kilowatt-hours (kWh) based on their power rating and usage time.

Purpose: It helps homeowners understand their electricity usage and plan solar power system requirements accordingly.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( E \) — Energy consumption (kWh)
• \( P \) — Power of appliance (watts)
• \( t \) — Usage time (hours)

Explanation: The power consumption in watts is multiplied by usage time in hours, then divided by 1000 to convert to kilowatt-hours.

3. Importance of Energy Calculation

Details: Accurate energy calculations help in sizing solar systems, estimating electricity costs, and identifying energy-saving opportunities.

4. Using the Calculator

Tips: Enter the appliance power in watts and daily usage time in hours. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Where can I find an appliance's power rating?
A: Check the label on the appliance, user manual, or manufacturer's specifications (usually in watts or kW).

Q2: How do I calculate monthly consumption?
A: Multiply the daily kWh result by 30 (or actual days in month) for monthly usage.

Q3: What's a typical power rating for common appliances?
A: LED bulb (10W), refrigerator (150W), TV (100W), AC (1000W), laptop (50W).

Q4: Should I use peak or average power?
A: For most appliances, use the rated power. For devices with variable loads, use average power if known.

Q5: How does this relate to solar system sizing?
A: Total your daily kWh needs across all appliances to determine the required solar panel capacity.
