PV solar energy was first discovered in the 1840s, when French physicist Edmond Becquerel first described the phenomenon of the photovoltaic effect. It was later developed by Bell Telephone Laboratories, and its silicium solar cells were used to power the Vanguard satellite in 1958. Support for PV systems began during the 1970s with the oil crisis, and the technology eventually gained popularity in the commercial market. Small PV markets grew throughout the 1980s, specializing in stand-alone systems for rural areas.
However, the benefits of PV solar energy do not stop there. PV panels in space are susceptible to the extremes of weather. Aside from weather, they may also be harmed by meteorites, comets, and other "space junk."
A typical PV system can cost anywhere from ten to twenty thousand pounds. Some incentives will reduce the cost by up to fifty percent. In the last few years, the cost of solar PV has come down significantly, and continues to do so. Installation costs vary considerably depending on the size of the array, the type of inverter, and the mounting system. But, in most cases, the initial investment will pay for itself within 25 years. PV solar energy systems are particularly economical for renovating roofs. Depending on the size of the array, the system can even be embedded into roof tiles.
With the advent of grid-connected PV systems, PV technology has gained tremendous popularity. According to the Earth Policy Institute, global PV production has increased by 48 percent every year since 2002. PV is the fastest-growing energy technology. As a result, the industry is investing heavily in R&D, with the primary objectives of reducing costs and improving efficiency. So, the future of PV solar energy lies in its price. There are many advantages to utilizing this technology.
The most compelling reason to install solar panels is its long lifecycle. It is possible to install a PV system that lasts for 10 or more years and has little maintenance once it is set up. The system also requires no ongoing intervention, and can function for as long as a hundred years. And, unlike fossil fuel-based energy, 97% of the energy produced will not contribute to the creation of harmful greenhouse gases or resources. It will pay for itself in no time at all.
As the cost of PV solar energy continues to decrease, the future of the world's climate is brighter than ever. Low-cost solar energy has the potential to transform the world's food supply and make medicine and mobile devices more accessible to a broad spectrum of people. PV solar energy is now mainstream and shows every sign of becoming the major source of clean energy. In the coming years, it will be mainstream. So, the next time you want to go green, make sure to get solar energy.
In addition to being a green option, PV solar panels can offset the cost of electricity. Many utility companies now offer time-varying rates for electricity that mirror the cost of production. Using a PV solar array can help offset the most expensive electricity in a household. If your household is already using a significant amount of electricity, you can use this energy to power some appliances. If you're looking to build your own solar energy system, be sure to research battery storage options. While domestic battery storage is expensive, it's becoming a viable option for residential solar energy.
As a sustainable energy source, PV is the answer for many people around the world. Solar PV has specific advantages in several ways, including no pollution and no greenhouse gas emissions. Additionally, the technology is scalable, and its production and development has increased dramatically in the U.S. over the past five years. There are currently more than a dozen countries in the world that use solar PV. And the number of new installations continues to increase.
PV solar energy systems can be small enough to power a calculator, or as large as a communications center. Large systems can power thousands of homes, and even the electric power grid. And there are countless sizes of PV arrays, so there's no limit to their potential for use. A PV array can be anywhere from one square foot to a city block. This technology is a viable option for the energy shortages that face the world today.
