What is Active Solar Energy
Active solar energy uses mechanical and electrical equipment to enhance the sun’s conversion of solar radiation to heat and electric power. Active solar energy systems require a solar collector, which is used to absorb solar energy. The most well-known solar collector is a solar panel system. Solar panels are made of photovoltaic cells, devices which directly convert solar radiation into useable electricity. A solar collector (or panel) heats the fluid through the panels and pumps it through a system of piping to heat a space or building or to store electricity for later use. The typical solar conductors used are air or liquid such as water or a special type of antifreeze. Other solar collectors may be solar towers, solar air heaters, flat-plate collectors, evacuated tube collectors, or solar bowls- all more complex systems for generating heat and electricity on grander scales.
Examples of Active Solar Energy
Liquid-based solar heating– Used for central heating and water heating in domestic systems
Room air heaters– Installed on a roof or home exterior, this system has a plate that is heated by the sun’s radiation. An electric fan or blower pulls the air from the room, heats it, and blows it back into the room.
Solar panels– Heat radiated from the sun is collected by solar panels, and transferred via air or liquid to provide electricity or heat for homes, buildings, or rooms. This is the most well-known type of active solar energy systems.
