Energy Calculator.pdf

To calculate basic energy needs for a solar generator, follow these steps:

1. List Equipment: Identify appliances to be powered, noting quantity and wattage.
2. Calculate Power Per Appliance: Determine wattage either by researching the appliance's specifications or by calculating it using volts and amps (Watts = Volts Amps).
3. Estimate Hours of Usage: Estimate daily and nightly usage hours for each appliance, considering their load profiles.
4. Calculate Appliance Daily/Nightly Energy Use: Multiply the number of units, watts, and hours of operation, then divide by 1000 to get kilowatt-hours (kWh) per day or night.
5. Find Total Energy Load: Sum the kWh/day for all appliances to determine the total energy needed from the solar generator system.

Key considerations include:
- Wattage of Common Appliances: Reference a chart or research specific appliances for accurate wattage.
- Load Profile: Understand how often appliances are "on" versus plugged in but not operating.
- Vampire Load: Account for small power draws from appliances when turned off but still plugged in.
- Calculations: Use the formula # Units Watts * hrs/day ÷ 1000 = kWh/day for each appliance, then sum these values for the total energy load.
