Systems Integration Basics. Solar-Plus-Storage 101. Solar panels have one job: They collect sunlight and transform it into electricity. But they can make that energy only when the sun is shining. That''s why the ability to store solar energy for later use is important: It helps to keep the balance between electricity generation and demand.

Capacitors used for energy storage. Capacitors are devices which store electrical energy in the form of electrical charge accumulated on their plates. When a capacitor is connected to a power source, it accumulates energy which can be released when the capacitor is disconnected from the charging source, and in this respect they are similar to batteries.

A wind turbine turns wind energy into electricity using the aerodynamic force from the rotor blades, which work like an airplane wing or helicopter rotor blade. When wind flows across the blade, the air pressure on one side of the blade decreases. The difference in air pressure across the two sides of the blade creates both lift and drag.
