Solar payback: Estimate annual solar production, electricity savings and a simple payback period.

Age 5 Explain it to a 5-year-old Start with a picture

Imagine measuring a room or household project before buying supplies or comparing running costs. Estimate annual solar production, electricity savings and a simple payback period.

Age 15 Explain it to a 15-year-old Connect it to the formula

Estimate annual solar production, electricity savings and a simple payback period. System size times annual production per kilowatt estimates energy output. Avoided electricity cost minus annual maintenance gives simple annual savings; financing, degradation and tax effects are excluded. Change one input or choice at a time and compare the result to see which part of the rule it controls.

College Explain it at college level State the model precisely

The browser applies the stated household-project or energy formula to the measurements and assumptions supplied. System size times annual production per kilowatt estimates energy output. Avoided electricity cost minus annual maintenance gives simple annual savings; financing, degradation and tax effects are excluded. Entries and results remain in this browser. Important results should still be checked against the records, standards, or rules that govern the real situation.
