Solar power works by converting energy from the sun into power. There are two forms of energy generated from the sun for our use – electricity and heat. Both are generated through the use of solar panels, which range in size from residential rooftops to ‘solar farms’ stretching over acres of rural land. Is solar power a clean energy source?
Energy from sunlight or other renewable energy is converted to potential energy for storage in devices such as electric batteries or higher-elevation water reservoirs. The stored potential energy is later converted to electricity that is added to the power grid, even when the original energy source is not available.
Yes, it can – solar power only requires some level of daylight in order to harness the sun’s energy. That said, the rate at which solar panels generate electricity does vary depending on the amount of direct sunlight and the quality, size, number and location of panels in use.
Solar energy can help to reduce the cost of electricity, contribute to a resilient electrical grid, create jobs and spur economic growth, generate back-up power for nighttime and outages when paired with storage, and operate at similar efficiency on both small and large scales. Solar energy systems come in all shapes and sizes.
In the United States, heating, ventilation and air conditioning (HVAC) systems account for 30% (4.65 EJ/yr) of the energy used in commercial buildings and nearly 50% (10.1 EJ/yr) of the energy used in residential buildings. Solar heating, cooling and ventilation technologies can be used to offset a portion of this energy.
There are several ways to turn sunlight into usable energy, but almost all solar energy today comes from “solar photovoltaics (PV).” Solar PV relies on a natural property of “semiconductor” materials like silicon, which can absorb the energy from sunlight and turn it into electric current.
The sun—that power plant in the sky—bathes Earth in ample energy to fulfill all the world''s power needs many times over. It doesn''t give off carbon dioxide emissions. It won''t run out. And it ...

Key Takeaways. Solar power harnesses the sun''s abundant solar radiation to generate electricity through photovoltaic or concentrated solar power technologies.; …
Solar power uses the energy of the Sun to generate electricity. In this article you can learn about: How the Sun''s energy gets to us; How solar cells and solar panels work
Solar power, also known as solar electricity, is the conversion of energy from sunlight into electricity, either directly using photovoltaics (PV) or indirectly using concentrated solar power. Solar panels use the photovoltaic effect to convert light into an electric current. Concentrated solar power systems use lenses or mirrors and solar tracking systems to focus a large area of sunlight to a hot spot, often …
The previous section looked at the energy output from solar across the world. Energy output is a function of power (installed capacity) multiplied by the time of generation. Energy generation is therefore a function of how much solar …
