Sizing Your Solar System. How much does one solar power battery hold. Watts Used by Appliances & Tools - DonRowe.com. How Many Watts Do You Need?
To select an inverter from DonRowe.com that has enough power for your application, add the watts for items you may want to run at the same time. Use the total wattage, plus 20%, as your minimum power requirement. Note: The wattage's given below are estimates. The actual wattage required for your appliances may differ from those listed. Check the nameplate on the appliance to determine the actual wattage required. * Appliances and tools with induction motors (marked * in tables) may require from 3 to 7 times the listed wattage when starting. F.Y.I. ..... Common Appliances Common Tools Pumps and Air Conditioners. Estimating Appliance and Home Electronic Energy Use. If you're trying to decide whether to invest in a more energy-efficient appliance or you'd like to determine your electricity loads, you may want to estimate appliance energy consumption.
Formula for Estimating Energy Consumption Use this formula to estimate an appliance's energy use: 1 kilowatt (kW) = 1,000 Watts Multiply this by the number of days you use the appliance during the year for the annual consumption in kWh per year. Estimating Annual Cost to Run an Appliance Multiply the annual consumption in kWh per year (that you calculated above) by your local utility's rate per kWh consumed to calculate the annual cost to run an appliance. Examples: (200 Watts × 4 hours/day × 120 days/year) ÷ 1000 = 96 kWh × 11 cents/kWh = $10.56/year [(120 Watts + 150 Watts) × 4 hours/day × 365 days/year] ÷ 1000 = 394 kWh × 11 cents/kWh = $43.34/year Wattage You can usually find the wattage of most appliances stamped on the bottom or back of the appliance, or on its nameplate.
Aquarium = 50–1210 Watts. How much electricity does an average 2-story 3-bedroom house use per day per month or per year. As an electrical engineer for a power company I see on average a house that is 1600-2000 square feet and having electric appliances except for the furnace use an average of 1500Kwatt-hours per month making 50 Kwatt-hours per day and a total of 18,000 Kwatt-hours per year.
If one is trying to determine usage as part of a plan for creating an alternative energy system for the house, one really needs to find out the actual usage for the house. Average numbers can be very misleading. Nova ran a story about a couple that installed a solar based 6 kWatt system who were generally running a surplus. No data is provided for actual consumption and converting the rating of a solar system back to Kwatts/day is moderately complex. On the other side of the spectrum, it has been reported that Al Gore's mansion uses about 221,000kWh per year.

This is a simplified, "lay persons'" overview of how solar energy systems calculations are made.
General Terms Photovoitaics (PV) is the direct conversion of light into electricity. What is a solar rating? The solar rating is a measure of the average solar energy (also called "Solar Irradiance") available at a location in an average year. The total daily Irradiation (Wh/sq-meter) is calculated by the integration of the irradiance values (W/sq-meter).
