Everyone is familiar with solar energy, from the wristwatch to a shower system leveraging on such technology. But what if this solar energy can be used on a larger scale, for example, to produce electricity?
Photovoltaic (PV) is made up of the words photo (light) and voltaic (electricity produced by chemical action). Making use of solar panels containing PV material, electricity is created by converting the sun’s rays into direct current electricity using semiconductors that produce the photoelectric effect. When sunlight comes into contact with the panels, a higher state of energy results, creating electricity.
Solar PV is renewable and locally-sourced, therefore reducing burning of fossil fuels as well as reliance on foreign energy sources.
PV installations most generate power for many years with little maintenance needed. Ongoing operating costs are extremely low compared to existing power technologies.
Generation of solar PV electricity does not release hazardous pollutants like carbon dioxide (CO2), sulphur dioxide (SO2), nitrogen oxides (NOx), volatile organic compounds (VOCs) and particulate matter (PM), which are also responsible for the effects of global warming.
Solar PV technology is a conscious decision and effort on supporting a commitment to be“green”, without sacrificing healthy financial returns. Rebates and incentives are available at country, state or federal levels to support the implementation of PV projects.
Solar is the Latin word for sun—a powerful source of energy that can be used to heat, cool, and light our homes and businesses. That's because more energy from the sun falls on the earth in one hour than is used by everyone in the world in one year.
A variety of technologies convert sunlight to usable energy for buildings. The most commonly used solar technologies for homes and businesses are solar water heating, passive solar design for space heating and cooling, and solar photovoltaics for electricity.
Businesses and industry also use these technologies to diversify their energy sources, improve efficiency, and save money. Solar photovoltaic and concentrating solar power technologies are also being used by developers and utilities to produce electricity on a massive scale to power cities and small towns.
These technologies harness heat from the sun to provide electricity for large power stations.
These technologies harness heat from the sun to warm our homes and businesses in winter.
These technologies convert sunlight directly into electricity to power homes and businesses.
These technologies harness heat from the sun to provide hot water for homes and businesses.
These technologies use solar energy to heat or cool commercial and industrial buildings
