The principles, applications, advantages and disadvantages of two common solar power generation technologies, photovoltaic power generation and photothermal generation are introduced.
Global State of Solar Photovoltaic (PV) Technology In 2017, worldwide solar cell production figures fluctuated between 18 GW and 27 GW. Since the year 2001, the total PV production has increased nearly two orders of magnitude, with annual growth rates ranging from 40% to 90% .
Photovoltaic technology has become a huge industry, based on the enormous applications for solar cells.
At the heart of its efficacy lies the efficiency of PV materials, which dictates the extent to which sunlight is transformed into electricity. Over the last decade, substantial advancements in PV efficiency have propelled the widespread adoption of solar PV technology on a global scale.
Photovoltaic (PV) efficiency refers to the ability of a photovoltaic device, such as a solar cell or solar panel, to convert sunlight into usable electrical energy. It is expressed as a percentage and represents the ratio of electrical power output to the amount of sunlight (solar energy) input.
The adoption of solar photovoltaic (PV) technology faces challenges, such as intermittency, high-energy storage costs, land-use conflicts, resource constraints, competition from other energy sources, initial cost barriers, integration into existing infrastructure, and environmental concerns.
An important strength of photovoltaic solar energy (PV) is that PV conversion can be realised with a multitude of materials and device designs and can be used for many different applications and markets.
Flywheels store rotational kinetic energy in the form of a spinning cylinder or disc, then use this stored kinetic energy to regenerate electricity at a later time.
Flywheel energy storage system (FESS) is an electromechanical system that stores energy in the form of kinetic energy. A mass coupled with electric machine rotates on two magnetic bearings to decrease friction at high speed. The flywheel and electric machine are placed in a vacuum to reduce wind friction.
The operational mechanism of a flywheel has two states: energy storage and energy release. Energy is stored in a flywheel when torque is applied to it. The torque increases the rotational speed of the flywheel; as a result, energy is stored. Conversely, the energy is released in the form of torque to the connected mechanical device .
Their efficiency is high during energy storage and energy transfer (>90 %). The performance of flywheel energy storage systems operating in magnetic bearing and vacuum is high. Flywheel energy storage systems have a long working life if periodically maintained (>25 years).
Small applications connected in parallel can be used instead of large flywheel energy storage systems. There are losses due to air friction and bearing in flywheel energy storage systems. These cause energy losses with self-discharge in the flywheel energy storage system.
In addition, this storage technology is not affected by weather and climatic conditions . One of the most important issues of flywheel energy storage systems is safety. As a result of mechanical failure, the rotating object fails during high rotational speed poses a serious danger. One of the disadvantages of these storage systems is noise.
Prof. Dr.-Ing. Günter Keller references including diagrams, figures and sketches. The input energy for a Flywheel energy storage system is usually drawn from an electrical source coming from the grid or any other source of electrical energy.
