Can PV pay back its energy investment?
With energy paybacks of 1 to 4 years and assumed life expectancies of 30 years, 87% to 97% of the energy that PV systems generate won’t be plagued by pollution, green-house gases, and depletion of resources. Based on models and real data, the idea that PV cannot pay back its energy investment is simply a myth.
Why is the integrated photovoltaic-energy storage-charging station underdeveloped?
The coupled photovoltaic-energy storage-charging station (PV-ES-CS) is an important approach of promoting the transition from fossil energy consumption to low-carbon energy use. However, the integrated charging station is underdeveloped. One of the key reasons for this is that there lacks the evaluation of its economic and environmental benefits.
What are the benefits of a photovoltaic-energy storage-charging station (PV-es-CS)?

What is energy payback?
Producing electricity with photovoltaics (PV) emits no pollu-tion, produces 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.
How does a PV system impact its life cycle?
Impacts over the life of PV systems are quantified using life cycle assessment (LCA) methods and can be used to estimate energy and carbon payback times. Energy payback time (EPBT) is the time required for a PV system to generate the same amount of energy used during system manufacturing, operation, and disposal.
