Solar Production Calculator – Forecast Your Energy Generation
Estimate daily, monthly, and yearly solar energy production based on your system size and sun hours.
Our interactive calculator helps you predict how much electricity your solar system can produce. Enter your system details and location profile to see accurate production estimates.
Why Calculate Solar Production?
Knowing how much energy your solar system can produce helps you make smarter decisions before and after installation. This calculator gives you:
- Daily, Monthly & Annual production forecasts
- Customized results based on sunlight profile or exact sun hours
- Charts & insights for better planning
- Comparison of production vs losses
How Our Solar Production Calculator Works
- Enter System Size (kW): Add the capacity of your solar system.
- Select Sunlight Profile (Good, Average, Poor): Quick estimate based on general conditions.
- Or Enter Custom Sun Hours: If you know your location’s average daily sunlight, enter it — it overrides the profile.
- Adjust Performance Ratio: Default 0.75 accounts for inverter, wiring, and dust losses.
- View Results Instantly: Get daily, monthly, and annual energy production with clear charts.
