PV Panels The Past With Energy Now

Photovoltaic cells have been improving since they were created. Their efficiency has also improved, and they are no longer as expensive. One PV cell usually cannot generate all of the power necessary by itself. Because of this, cells are grouped to make modules, also called solar panels. Read on and find out that PV panels will be one of the most reliable forms of energy in the future.

The term photovoltaic is a Greek word that means both light and electric. The term has been used in the English language since 1849. The photovoltaic effect was discovered in 1839, but the first cell was not actually built until 1883 by Charles Fritts. The first really efficient cell was developed by Chapin, Fuller, and Pearson in 1954.

A single solar panel can power a small amount of electricity however, for large amounts of electricity, panels are put into what are known as arrays. Arrays are multiples of modules that can produce large amounts of electricity to power a home or even a power plant. Until very recently, panels have been far too expensive to consider for the average consumer.

Cells require protection from the wind, rain, etc. They are normally placed between glass to protect them. These cells are connected inside the module in a series pattern. A series means that the circuitry is connected in such a way that the current will pass through all of it.

Connecting cells in parallel yields higher currents. Modules can be connected together in an array by series or parallel until a desired direct current (DC) voltage and current are reached. The output of power from a solar array is measured in watts or kilowatts.

The energy is then processed by an electricity grid and then an inverter in order to make the best use of it. Batteries can be used to store any extra energy that is not used at that time if the system is a stand-alone. There are many solar gadgets on the market that operate in this same fashion.

There are financial incentives available for individuals and business owners alike in many different countries to change to forms of renewable energy. The financial incentives for solar energy are especially great. This is the perfect time for a conversion of your business or home, and you can make a difference in the world at the same time. There is renewable energy being wasted every day, more than we can ever use, while our natural resources are being rapidly drained.
