Several mapping services and tools are available to help you determine your home''s solar energy potential. Some of the services also offer information on the estimated ...
How Do Clouds Affect Solar Energy?
You may have seen solar panels on the roof of a house or other building. These solar panels capture light energy from the sun and convert it into electricity that can be used by the people inside. Some power companies use solar panels as a source of electricity, too. However, clouds can block light from the sun.
Solar power
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.
