Solar electricity calculator

The calculator assesses the savings and payback for a simple domestic solar PV system only – at present it is not configured to assess the impact of including storage technologies such as an immersion diverter or a battery. Factoring in the costs and savings arising from these additional technologies will change the savings and 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.

How do you calculate a payback period?

The simplest way to model the payback period is to divide the project''s costs by the expected annual production number offered by the calculator. That''s a good start, but it probably won''t tell us the whole story. Your actual payback period will need to consider tax credits, net metering, and state incentives.

Solar Cells : Energy Payback Times and Environmental Issues

Energy payback time (EPBT) is a basic metric of this performance: The lower the EPBT, that is the time it takes for a PV system to generate energy equal to the amount used in its production, the lower will be the emissions to the environment because emissions mainly occur from using fossil fuel–based energy in producing materials, solar cells

How do you calculate energy payback?

Payback calculations are based on paying back this electricity with PV electricity produced by installed modules. Thus, the equation energy payback is simply: Energy used to make system (in kWh/unit area) ÷ Energy produced by system (in kWh/unit area-time).

Solar Payback Period

The payback period is the amount of time it takes for solar system owners to recoup their solar investment, usually expressed in years. The customer''s financial savings from the system are factored in, such as net metering credits on utility bills, the federal solar tax credit, utility solar incentives, and solar renewable energy certificates (SRECs).
