Solar energy is a renewable energy source that harnesses the power of the sun's rays to generate electricity. This is achieved through the use of photovoltaic (PV) cells, which convert sunlight into DC electricity. Solar energy is a sustainable and environmentally friendly alternative to fossil fuels, as it does not emit harmful greenhouse gases. With the decreasing cost of solar technology, it has become more accessible to homeowners, businesses, and communities. Solar energy has the potential to play a significant role in reducing our dependence on non-renewable energy sources and mitigating the impacts of climate change.
