In energy sector Ultracaps have also found a lot of usage. Thus, ultracapacitors as used in the pitch control of wind power plants. The most important aspect for ultracapacitors is here the long lifetime, low maintenance and insensitivity to acceleration forces.
In solar energy, you will find ultracapacitors for short-term storage, to make stable the power supply for short-term shading of the solar modules. The decisive criterion here is the long lifetime and fast availability.
Due to the long lifetime and maintenance-free small cells replaces conventionell batteries or rechargeable batteries more and more in smart meters and various controllers.
