FREQUENTLY ASKED QUESTIONS

WHAT IS SOLAR ENERGY AND HOW DOES IT WORK?

Solar energy refers to the energy harvested from sunlight, which can be converted into thermal or electrical energy through various technologies. Primarily, solar panels contain photovoltaic cells that convert sunlight directly into electricity. When photons from sunlight strike the semiconductor material in these cells, they excite electrons, creating an electric current. Additional components, such as inverters, are employed to convert the direct current (DC) produced by solar panels into alternating current (AC), which is used by most homes and businesses. Energy can be consumed immediately or stored in battery systems for later use.

This technology symbolizes a significant advancement in renewable energy efforts, offering an alternative to fossil fuels. The reduction of greenhouse gases and commitment to sustainability underpins the global movement towards embracing solar power. As solar technologies continue to evolve, their efficiency and affordability significantly enhance their viability for widespread application across commercial, residential, and industrial sectors.
