Useful Questions

What are the annual running costs of a Photovoltaic Park?

Function costs are relatively small. In detail we the policy of the station, the electricity bill to buy power for the purpose of the alarm, and security system etc. and then dial the account for remote management capabilities, dispatch information.

It guaranteed the sale of energy generated for 20 years?

Yes it is, and signed a contract of sale between the producer and the Hellenic Transmission System Operators for Electricity.

The selling price is fixed?

The sales price is locked in signing the contract with the Hellenic Transmission System Operator for 20 years. Each year, an increase in the inflation criteria and the selling price in the tariffs of electricity.

How do Photovoltaics Work?

Photovoltaics is the direct conversion of light into electricity at the atomic level. Some materials exhibit a property known as the photoelectric effect that causes them to absorb photons of light and release electrons. When these free electrons are captured, an electric current results that can be used as electricity.

The photoelectric effect was first noted by a French physicist, Edmund Bequerel, in 1839, who found that certain materials would produce small amounts of electric current when exposed to light. In 1905, Albert Einstein described the nature of light and the photoelectric effect on which photovoltaic technology is based, for which he later won a Nobel prize in physics. The first photovoltaic module was built by Bell Laboratories in 1954. It was billed as a solar battery and was mostly just a curiosity as it was too expensive to gain widespread use. In the 1960s, the space industry began to make the first serious use of the technology to provide power aboard spacecraft. Through the space programs, the technology advanced, its reliability was established, and the cost began to decline. During the energy crisis in the 1970s, photovoltaic technology gained recognition as a source of power for non-space applications.

What is it and how they work, the photovoltaic panels?

The solar panels consist of a context in which those modules (or cells). The characteristic of the photovoltaic cells that convert sunlight into electricity. On the back of photovoltaic panels leaving two wires (positive and negative + -) from which we get the DC.
