The study found that the levelized cost of electricity (LCOE) for ground-mounted PV projects could be as low as €0.041/kWh (US$0.045/kWh), making it the lowest and most cost-effective power generation technology.
Onshore and offshore wind power is also the cheapest, at around 5-10 euro cents/kWh, and some other solar projects, including small rooftop PV (no more than 0.15 euros/kWh) and ground-mounted PV with batteries (no more than 0.11 euros/kWh), are also the cheapest in Germany.
The figure above shows that in Germany, nuclear power has the highest technology cost, with an LCOE of up to 0.5 euros/kWh, but it also has the largest LCOE range of all technologies. At the same time, renewable energy technologies are not only low-cost, but also have a narrow LCOE range in most cases.
The exception is small rooftop photovoltaic power generation with energy storage system (BESS), whose LCOE is as high as 0.225 euros/kWh, the highest among renewable energy technologies. Fraunhofer ISE researchers believe that the huge difference in battery system costs caused by different solar radiation levels exacerbates the inherent cost differences of solar energy systems.
In the next few years, the LCOE of renewable energy technologies will further decline. It is expected that by 2045, the LCOE of small rooftop photovoltaic systems may be as low as 0.049 euros/kWh, while the LCOE of ground photovoltaics may be as low as 0.031 euros/kWh.
The LCOE of small photovoltaic battery systems may be as low as 0.19 euros/kWh, which is an encouraging development for the energy storage industry and the renewable energy power generation industry.
