Production costs for Electricity with Photovoltaics

Simple calculator for the electricity generation costs for a photovoltaic system. The production costs indicate how much it costs to produce electricity. The total costs of the system are divided by the amount of electricity generated over its entire lifespan. Of course, these values can only be known exactly in retrospect. In order to find out the production costs before the system is constructed, the values must be estimated. Fortunately, this can be done quite well with photovoltaics; the system itself lasts a very long time, only estimating the expected lifespan of the inverter is more difficult. The annual yield is also easy to plan.
Please enter the total costs of the photovoltaic system and the service life and annual yield or total yield. The production costs for one kilowatt hour and for any amount of electricity will be calculated.
The production costs are better, the lower they are. To put it simply, a photovoltaic system is worthwhile if the production costs are below the price of electricity.

Total cost: €, $
Lifespan: Jahre
Annual yiels: kWh
Total yield: kWh

Production costs per kWh: cents

Production costs per :

Example: if the system, including replacing the inverter after 15 years, costs €12,000, lasts for 30 years and generates 5,500 kilowatt hours per year, then 165,000 kilowatt hours of electricity will be generated over its lifespan. The production costs are just under 7.4 cents per kilowatt hour and 72.73 euros for a megawatt hour.

Since the beginning of the 2000s, the costs for photovoltaic systems and thus also the electricity production costs have been reduced enormously due to advances in technology and mass production. In 2009 they were over 30 cents per kilowatt hour, in 2024 they will be under 5 cents for open-space systems and under 10 cents for private roof systems. And this despite the fact that the price of electricity has tended to rise since then.
