Question

List two merits of Solar cells.

Answer 1

Hint: Cell, in biology, the essential membrane-bound unit that contains the elemental molecules of life and of which all living things are composed. one cell is usually an entire organism in itself, like a bacterium or yeast. Other cells acquire specialized functions as they mature.

Complete Answer:
Advantages of Solar Cells:
1. Renewable energy - The energy is often used both to get electricity and warmth within the house. Renewable energy is recovered from the sun, the wind and waves - which during this case is that of the sun.
2. Environmentally friendly energy - With solar cells, almost no pollution.
Merits of photovoltaic cell
Solar power is pollution free and causes no greenhouse gases to be emitted after installation.
The energy is often used both to get electricity and warmth within the house.
Maintenance cost is low.
Solar energy is employed in cars.
Solar cells are very useful in powering space vehicles like satellites and telescopes (e.g. Hubble). They supply a really economical and reliable way of powering objects which might otherwise need expensive and cumbersome fuel sources.
The most commonly used solar technologies for homes and businesses are solar photovoltaics for electricity, passive solar design for space heating and cooling, and solar water heating.

Note:
A photovoltaic cell may be a device that directly converts the energy of sunshine into electricity through the photovoltaic effect. Solar cells or photovoltaic cells are made to support the principle of the photovoltaic effect. They convert sunlight into DC (DC) electricity.
