What is the energy payback time for thin film PV systems?

Knapp and Jester studied an actual manufacturing facility and found that, for single-crystal-silicon modules, the actual energy payback time is 3.3 years. This includes the energy to make the aluminum frame and the energy to purify and crystallize the silicon. What is the Energy Payback for Thin-Film PV Systems?

How does electricity affect solar payback?

The amount of electricity your household uses monthly, as well as the cost of electricity in your area significantly influences your solar payback period. The higher your electric bill, the greater the savings and the faster you’ll reach your payback period.

Is photovoltaic energy payback a good idea?

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.

Can PV pay back its energy investment?

With assumed life expectancies of 30 years, and taking into account the fossil-fuel-based energy used in manufacture, 87% to 97% of the energy that PV systems generate won’t be plagued by pollution, greenhouse 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.

How do solar energy costs affect your return on investment?

Specific energy costs in your area also directly impact your return on investment (ROI) from your solar power system. The higher your monthly electricity bill, the more quickly you tend to recoup your investment because it shortens your payback period.

How does a PV module pay back?

Most of the energy that goes into manufacturing a PV module is in the form of electricity (kWh). Payback calculations are based on paying back this electricity with PV electricity produced by installed modules.
