Energy Conversion Formula:
From: | To: |
The Watt to Unit conversion calculates energy production (in kilowatt-hours) from solar panels based on their power rating and operating time. This helps estimate potential energy generation for solar power systems.
The calculator uses the energy conversion formula:
Where:
Explanation: The formula converts watt-hours to kilowatt-hours by dividing by 1000, since 1 kilowatt equals 1000 watts.
Details: Accurate energy calculation is crucial for sizing solar power systems, estimating electricity production, and calculating potential savings or return on investment.
Tips: Enter the solar panel's rated power in watts and the expected operating time in hours. Both values must be positive numbers.
Q1: How accurate is this calculation for real solar systems?
A: This gives theoretical maximum. Real systems have efficiency losses (typically 70-90% of theoretical).
Q2: What's the difference between watts and watt-hours?
A: Watts measure power (rate of energy use), watt-hours measure energy (power × time).
Q3: How many kWh does a typical solar panel produce?
A: A 300W panel in full sun for 5 hours would produce 1.5 kWh (300 × 5 / 1000).
Q4: Can I use this for battery capacity calculations?
A: Yes, this helps estimate how much energy a battery needs to store for given loads.
Q5: How does this relate to my electricity bill?
A: Most utilities charge by kWh, so this helps estimate how much solar energy offsets your bill.
