Solar maintenance revenue loss calculator

Calculate lost production and lost production value with your own figures.

Your numbers

Use the units shown. Results update as you change valid inputs.

Choose the currency for these amounts. Changing it keeps your numbers and does not convert exchange rates.

Use lost production and lost production value to compare changes to your inputs. The method and limits below explain the scope.

Examples

Examples

Try the starting example

Expected interval production (kWh)
10,20,30,20
Outage fraction per interval (fraction)
0,1,0.5,0
Value of energy by interval (USD/kWh)
0.1,0.2,0.2,0.1
Lost production (kWh)
35
Lost production value (USD)
$7.00

Try another scenario

Expected interval production (kWh)
[10, 21, 30, 20]
Outage fraction per interval (fraction)
[0, 1, 0.5, 0]
Value of energy by interval (USD/kWh)
[0.1, 0.2, 0.2, 0.1]
Lost production (kWh)
36
Lost production value (USD)
$7.20
Calculation method

Calculation method

Lost production (kWh)

Apply supplied outage fractions to aligned production profile and value each interval.

Lost production value (USD)

Apply supplied outage fractions to aligned production profile and value each interval.

Symbols and units
a
Expected interval production (kWh)
b
Outage fraction per interval (fraction)
c
Value of energy by interval (USD/kWh)

Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.

Assumptions & limits

Assumptions & limits

  • User-supplied measurements and assumptions; Apply supplied outage fractions to aligned production profile and value each interval. Supported limits: Finite numeric values bounded to 1e9 magnitude; lists and tables contain 1–100 records unless a stricter bound is stated. Inputs use the units shown. Lists explicitly paired by a method must have matching lengths; independent polynomial coefficient vectors may differ. Respect stated physical, interpolation, policy and computational domain limits.
