Solar Energy Production Calculator vs Solar Panel Degradation Calculator
Two calculators for the same neighbourhood of questions. Here is what each measures, what you feed in, and where you'd reach for one over the other.
Solar Energy Production Calculator
Estimate how many kilowatt-hours your solar system will produce each year, accounting for efficiency losses and panel aging. Ideal for sizing a system or projecting long-term energy output before purchase.
- Answers
- Annual Energy Production (kWh)
- Inputs
- System Size, Peak Sun Hours, System Efficiency, Annual Degradation, System Age
Solar Panel Degradation Calculator
Project how much energy your solar panels will produce in any future year as their output gradually declines with age. Use it to model long-term performance, verify warranty compliance, and forecast lifetime energy generation.
- Answers
- Production After Degradation (kWh/year)
- Inputs
- Initial Annual Production, Annual Degradation Rate, Years of Operation
