PV Modules - An Energy Source for the Present to Get Us Into the Future

pv modulesPV Modules, aka Photovoltaic Modules are more conventionally referred to by laypeople as solar panels. These, by either name, are poised to help feed the growing worldwide energy demand by enabling energy providers or even individuals to rely on supplying their electricity by harvesting the sun’s energy, which is still available to be used for free! The conversion of the energy derived from harnessing the energy of the sun is done by the use of photovoltaic modules, or solar panels. Until recently the generous availability of the sun’s rays and energy had been tempered somewhat by both the high cost of producing the solar cells, which made installing enough panels to create usable amounts of electricity too expensive for all but specialized users and the problems of storing the electricity for later use when the sun went down or on cloudy days. Recent advances are driving down the cost of solar energy and are putting it within reach of more and more people and businesses.

In these photovoltaic modules, or solar panels, light energy is converted directly to electrical energy. Nothing has to be burned to make heat to drive a generator. Solar electric power can go directly to the power grid, which can then be used to add to the energy available to be consumed just as fossil fuel contributes to the energy needs powering the modern world. Fossil fuel electrical generation requires boilers, turbines and generators, not to mention the devices required to dig, pump and transport the coal or oil. All the machinery involved in this process is expensive and highly complicated to run and maintain. Solar panels have none of these problems. All you need is sun, solar panels, space to put them and a way to store the electricity generated for later use.

Early on the expense of both the panels and of the batteries used to store electricity deterred all but those who either
lived too far from the power grid, who needed electricity where there was no grid at all in developing nations or unmanned or specialized situations such as highway signs or even space stations. The graceful wings of the International Space Station are solar panels. In the early days the cost of producing a solar panel was about $100 US per watt. Consider in comparison that the modern home requires close to 1000 kilowatt hours per month or about 33.33 kilowatt hours per day. Without going into a lot a math it was safe to say that the cost of using solar panels was “out of this world.”

Photovoltaic Modules ( PV Modules) are devices that convert sunlight into usable electricity.  

PV Modules are ready in mass use around the globe in devices such as calculators and watches.  

The utilization of pv modules in other products such as appliances and home electricity systems is growing rapidly

Solar panels now cost less than $5.00 US per watt and that cost is dropping rapidly. Electric power companies faced with the ever- increasing cost of building and maintaining fossil fuel plants are seeing solar energy not only as a basic solution to the energy problem, but also one that relieves the companies of the cost of building additional plants.

Businesses and even individuals are seeing the advantage of putting solar power arrays on the roofs of factories and homes. Electric power companies are offering to buy excess power produced by the existing solar energy production, making the cost of solar power far less since the idea of investing in batteries for storage of surplus solar power became unnecessary. Solar panel-equipped businesses and homes can enjoy watching their electric meters slow to a crawl or even run backwards as they contribute power to the grid. This can allow power companies to idle expensive power plants, running them only at night and saving wear, tear and the use of costly fossil fuels. Companies are even bringing to market roofing shingles that double as solar panels. The future of solar panels is bright!
