Energy payback time (EPT) is the time required for a generation technology to generate the amount of energy that was required to build, fuel, maintain and decommission it. The EPT is closely linked to the energy payback ratio and depends on assumptions made on the lifetime of a technology [59,70–73].
The EPT is closely linked to the energy payback ratio and depends on assumptions made on the lifetime of a technology [59,70–73]. EPT also exists as a criterion for LCA analysis of different technologies. Table 3 lists the EPT of different power system technologies . Table 3. Energy payback time of electricity generating technologies .
The energy payback time (EPBT) is an index used to determine the time required for a system/design to recover the energy used during its manufacturing and production process.

The Payback Period (PBP) is an indicator that aims at expressing the time to recover the investment in a project. The PBP is the number of years or months necessary for the gross value of the inputs and outputs to be equal . PBP can be used with or without considering the time value of money.
It is based on a non-dimensional scale while NPV represents a monetary quantity. The Payback Period (PBP) is an indicator that aims at expressing the time to recover the investment in a project. The PBP is the number of years or months necessary for the gross value of the inputs and outputs to be equal .
Another LCA study presented at the 21st European Photovoltaic Solar Energy Conference in Germany in 2006 resulted in an energy payback time of 2 years in Southern Europe and 3–3.5 years in Middle-Europe with little variation between mono- and polycrystalline cells.
