What is Solar Energy?
Solar energy refers to the radiant energy emitted by the Sun, which is harnessed and converted into usable forms of power, such as electricity and thermal energy.
Was sind Fotovoltaik Anlagen?
Photovoltaikanlagen sind Stromversorgungssysteme, die mittels Photovoltaik nutzbaren Solarstrom liefern. Einfacher ausgedrückt: Photovoltaikanlagen nehmen das Sonnenlicht direkt auf und wandeln es in Strom um.
Wie funktionieren Photovoltaikanlagen, und aus welchen Komponenten bestehen sie?
Photovoltaikanlagen wandeln das Sonnenlicht direkt in Strom um, und dazu benötigt das System die folgenden Komponenten;
What are the Photovoltaic (PV) Systems?
PV systems, or photovoltaic systems, are technology setups designed to convert sunlight directly into electricity using solar panels. These systems are based on the photovoltaic effect, where certain materials (typically silicon-based) generate electric current when exposed to sunlight.
Monocrystalline Panels
Monocrystalline panels are the most improved and latest technology of PV panels with the cells which are composed of single pure silicon crystal that is cut into several wafers. With the use of the single pure silicon, these panels are the most space-efficient, highest power capacity and longest lasting among all the photovoltaic panels.
Polycrystalline Panels
Polycrystalline panels are composed of different silicone crystals, where they are melted and poured into a square mold. This technique makes the polycrystalline panels much affordable but less efficient at the same time.
Passivated Emitter and Rear Cell (Perc) Panels
PERC panels are the PV panels which their technology captures the insufficiently absorbed sunlight through an additional layer on the back of their solar cells. Due to the added materials and its greater technology, these panels are more expensive and provides greater efficiency.
Dünnschicht-Paneele
zeichnen sich durch sehr feine Schichten aus, die so dünn sind, dass sie flexibel sind. Diese Platten benötigen keinen Rahmen und sind viel leichter und einfacher zu installieren. Aufgrund ihrer Schichtstruktur sind sie jedoch wesentlich weniger effizient als typische Silikonpaneele.
Off-Grid (Standalone) Systems
Off-grid systems are the solar photovoltaic systems that generate electricity and store that power in solar batteries and run independently from the power grid at all times. These systems give off-grid sites the ability to generate energy without grid connection.
On-Grid (Grid-Tied) Systems
On-grid systems are electricity generating photovoltaics systems that are connected to the utility grid. These systems consist of PV panels, one or several inverters, a power conditioning unit and grid connection equipment.
When conditions are right, On-Grid systems supply the excess power, beyond consumption by the connected load, to the utility grid. In other words, customers of the on-grid systems are then compensated or credited for their generated power which they do not use and fed to the grid.
