Solar panels

A solar battery is a combination of photovoltaic converters (solar cells) – semiconductor devices that directly convert solar energy into direct electric current, as opposed to solar collectors that heat the heat carrier material.
Various devices that allow converting solar radiation into thermal and electrical energy are the object of research in solar energy (from Greek Helios Ήλιος, Helios – the Sun). The production of photovoltaic cells and solar collectors is developing in different directions. Solar panels come in a variety of sizes, from embedded in microcalculators to rooftop cars and buildings.
