Solar power is energy obtained from sunlight that is converted into usable forms through solar panels. Solar panels either convert sunlight directly into electricity via photovoltaic panels or use it to heat water or other fluids for heating and washing via solar thermal panels. Germany is currently the world leader in solar power production and usage. While solar power provides renewable energy and reduces environmental impacts, issues include the large amounts of land needed for solar farms and hazardous materials used in panels that must be properly disposed of.
