Solar power is cleaner than electricity from fossil fuels, so can be better for the environment. Solar power does not lead to harmful emissions during operation, but the production of the panels creates some pollution. The carbon footprint of manufacturing is less than 1kg CO2/Wp, and this is expected to fall as manufacturers use more clean electricity and recycled materials. Solar power

Solar panel

Solar array mounted on a rooftop. A solar panel is a device that converts sunlight into electricity by using photovoltaic (PV) cells. PV cells are made of materials that produce excited electrons when exposed to light. The electrons flow through a circuit and produce direct current (DC) electricity, which can be used to power various devices or be stored in batteries.
