Solar Energy
What is it?
energy from the sun that is converted into thermal or electrical energy
This energy is in the form of solar radiation, which makes the production of solar electricity possible
cleanest and most abundant renewable energy source available, and the U.S. has some of the richest solar resources in the world.
What do we use it for?
generating electricity, providing light or a comfortable interior environment, and heating water for domestic, commercial, or industrial use
Types of Solar Energy
Passive
Active
Photovoltaic
Solar Thermal
Passive
A method in which solar energy is harnessed in its direct form without using any mechanical devices.
Example: Drying clothes in the sunlight
Active
Employs mechanical or electrical equipment for functioning and increase system efficiency
Example: Water pumps are used to circulate water through the active solar energy water heating system
Photovoltaic
convert sunlight directly into electricity. PV gets its name from the process of converting light (photons) to electricity (voltage), which is called the PV effect
Example: solar panels on a roof or solar farms (used to speed the process of direct sunlight)
Solar thermal
uses the sun’s energy, rather than fossil fuels, to generate low-cost, environmentally friendly thermal energy
his energy is used to heat water or other fluids, and can also power solar cooling systems
Benefits
It reduces Utility bills
Reduces carbon footprint
