The energy payback time (EPBT) of a power generating system is the time required to generate as much energy as is consumed during production and lifetime operation of the system. The past decade the energy payback time for solar PV systems has been reduced drastically.
The energy payback time is influenced by the following three factors: 1. Energy payback time and materials used Over the past years, manufacturers of silicon wafers have been able to reduce the thickness of the wafer and therefore reduce the costs of the solar cell significantly.
Producing electricity with photovoltaics (PV) emits no pollution, pro-duces no greenhouse gases, and uses no finite fossil-fuel resources. The environmental benefits of PV are great. But just as we say that it takes money to make money, it also takes energy to save energy. The term “energy payback” captures this idea.
The most accurate payback period will also take into account external factors, such as the long-term trend for electric rates to increase and the degradation of your solar panels production over time. Consider a 6.4kw solar project scheduled to be installed on a sunny site in eastern Massachusetts.
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 environmental benefits of PV are great. But just as we say that it takes money to make money, it also takes energy to save energy. The term “energy payback” captures this idea. How long does a PV system have to operate to recover the energy—and associated generation of pollution and CO2—that went into making the system, in the first place?
Energy Payback Time
Energy payback time (EPBT) is defined as the time required for the solar PV system to generate the same amount of energy used in its entire life cycle starting from raw materials extraction up to construction and decommissioning phase [101].
