Solar energy is one of the most abundant forms of renewable energy available to the world. Photovoltaic cells are used to convert the energy from the sun into electric power. This is done by a process called the photovoltaic effect. Continue reading and learn about photovoltaics and their role in the future of renewable energy.
You can characterize solar technology by how it can be captured. It is captured in one of two ways, either passively without the use of any electrical or mechanical device like a solarium. It is also captured actively which would use some type of electrical or mechanical equipment for assistance. A photovoltaic cell can be used either way.
The photovoltaic effect involves creating voltage in whatever material is being exposed to electromagnetic radiation. The material is then charged with solar power. This effect was first noticed in 1839, by Alexandre-Edmond Becquerel.
In one year, the amount of solar energy that falls to the surface of the earth is so enormous that it will surpass by double the amount of non-renewable energy sources of coal, oil, natural gas, and mined uranium on the earth. The levels of solar power that can be captured in the world are different, depending on the area that it is being captured in. Areas closer to the equator will capture more solar power.
Spacecraft and orbiting satellites were the first to use the photovoltaic cell. The cells are now used for many things including power. A cell module or a solar cell can produce a direct current, and to be used for residential and commercial use, it then needs to be converted to alternating current.
Initially it was expensive to try and install a photovoltaic system, however, there are new governmental incentives in several different countries encouraging its use. Recent events have proven that now more than ever, it is time to change to renewable energy. Panels have become much less expensive to produce and install in recent years aside from incentives.
When photovoltaic cells were first introduced to the public, they had menial uses, such as calculators and gadgets, but now, we are testing roadway lighting systems. The presence of them can be seen in street lamps, parking meters, and phones. There are power stations in different areas of the world in operation with photovoltaic panels. There is no doubt that the need for them will grow with the need for renewable energy.
