Solar energy is derived from the sun's rays, which consist of electromagnetic radiation.

Monocrystalline silicon solar cells are widely used in commercial solar panels due to their high efficiency and long lifespan.

A solar inverter converts the direct current (DC) electricity generated by solar panels into alternating current (AC) electricity, which is compatible with the electrical grid and household appliances.

China has the largest installed solar PV capacity in the world, followed by the United States, Germany, and India.

Solar energy does not produce greenhouse gases during electricity generation, making it a clean and sustainable source of energy.

The Paris Agreement is an international agreement that aims to limit global warming and promote the transition to sustainable energy, including solar energy.

The intermittency of solar energy, due to variations in sunlight, poses challenges for grid integration and maintaining a stable electricity supply.

Concentrated Solar Power (CSP) systems use mirrors or lenses to concentrate sunlight onto a receiver, generating high temperatures to produce electricity or heat.

The Solar Photovoltaic Effect is the process by which certain materials generate an electrical current when exposed to sunlight.

Photovoltaic (PV) systems use solar panels to convert sunlight directly into electricity.

The type of solar cell material used in a solar panel is the primary factor that determines its efficiency in converting sunlight into electricity.

Solar thermal systems use solar collectors to absorb sunlight and generate heat, which can be used for various applications such as space heating, water heating, or industrial processes.

The high cost of solar energy systems, particularly the installation costs, is a primary challenge that hinders their widespread adoption.

Hybrid solar systems combine solar PV and solar thermal technologies to generate both electricity and heat from sunlight.
