Costs

Cost is established in cost-per-watt and in cost-per-watt in 24 hours for infrared capable photovoltaic cells. Manufacturing costs are also calculated including the energy required for manufacturing of the cells and modules in a kWh basis. These figures are added to the end price for solar investors and the energy payback is calculated from the point of power plant initialization or connection to the grid. another method of calculating the payback is to use the feed in tariff mechanism in place for power plant remuneration. Solar-specific feed in tariffs vary worldwide, and even state by state within various countries. The energy payback time will vary depending on the country of application and the level of the feed in tariff.
