PHOTOVOLTAIC POWER SYSTEMS

Installing a photovoltaic power system is a RESPONSIBLE CHOICE because it respects the environment, contributes to reducing the exploitation of natural resources and decreases gas emissions causing air From an economic perspective it is a long- term investment, as it has a fixed cost which is not influenced by economic or energetic crises, or can even provide a fixed income if the energy produced is sold to an electricity Advantages of a photovoltaic power system: • Reliability and small amount of maintenance. • Self-production of electric energy if necessary, or alternatively, handover to the...

THE IDEA OF A PHOTOVOLTAIC SYSTEM SOLAR RADIATION AND TERRITORY Sunlight is a vital source of energy which can provide our planet with an amount of power, in the form of solar radiation, about 1.100 times greater than what it actually needs and with an average solar irradiance of 1367 Watts per square meter, which is called “solar constant” . Europe’s geographical position is characterized by an excellent insolation, which makes it an ideal area for the adoption of photovoltaic systems. Solar electricity (kWh/kWp) Yearly sum of global incident solar radiation on optimally-inclined south-oriented...

MONOCRYSTALLINE AND POLYCRYSTALLINE SILICON MODULES THE PHOTOVOLTAIC EFFECT AND DIFFERENT TYPOLOGIES OF SOLAR CELLS The photovoltaic effect is the creation of voltage by a device, called “solar cell” (mainly made of silicon) which converts solar radiation (power from sunlight) into electricity. The solar cell is the photovoltaic module key element, able of turning solar energy into electricity. When the cell is hit by sunlight, solar radiation photons release their power creating a ux of electric charges. Silicon is the most used material in the production of solar cells and in Earth’s crust...
