Photovoltaic energy is the conversion of sunlight into electrical energy.
It is part of the renewable energy and feeds all types of appliances and electrical systems.
Photovoltaics can be used in two ways : either it is connected to the mains (for homes, the large roofs of public buildings, …) and injected directly into the network,
either it brings electricity to isolated sites (solar power plants, solar pumping …), who immediately benefits from the energy required
To use the majority of electrical appliances, It is necessary to convert the direct current generated by the solar panels power AC. This principle is done through an inverter integrated photovoltaic solar installation.
Principle of operation
Principle of said operation "connected to the network. : very simple and strong economic !
The so-called solar photovoltaic modules generate direct current…
Thanks to an inverter, This current is transformed to current alternative that is consumed by your usual electrical appliances. The inverter is a simple wall-mounted.
All of the current is injected back into the public distribution network. By contract, EDF or the electricity authority buys you the current re-injected at a rate agreed by order. For this, the system must include a counter EDF and more, called resale counter.
A growth rate of 250 %
The french photovoltaic market connected to the network has experienced between 2003 and 2006 a growth rate of 250 % in terms of power funded.
Average consumption of a household (without heating) is of approximately 3500 kWh per year. By hunting to the wasteful, You can easily descend to 2500 kWh.
Faced with the negative consequences of the greenhouse effect and the increase in the price of a barrel of oil, Today, we rediscover the advantages of solar energy, largely forgotten in recent decades for the benefit of cheap fossil fuels. The Sun produces energy in abundance, much more than what we can consume : It provides continuously about 10 000 time consumption of mankind, with a life expectancy of several billion years.
