Undoubtedly, photovoltaics is a technology that will allow us to contribute in the near future, a cleaner world, starting from an environmentally sustainable energy system.
energy self-sufficiency, including an individual dwelling, would allow a global limit significantly the use of fossil fuels.
Now, thanks to a photovoltaic system, can transform your home into a small power plant thanks to a non-polluting and inexhaustible source: the sun. The solution is to install
roof or floor a photovoltaic system and also benefit from the incentive mechanism to encourage the public "in regard to energy." Through it, the electricity produced by the plant is paid for twenty years as the Manager of Electrical Services (GSE Spa). Adding up the energy savings from Service of the bill to gain from the sale of every kilowatt produced by your system, it is clear that the operation in the medium term (8-9 years to recoup the cost of the system) is convenient.
plants for producing electricity through photovoltaic technology presents many advantages, among which the most significant are:
- absence of any type of pollutant emissions;
- savings of fossil fuels;
- extremely reliable because there are no moving parts (useful life of more than 25 years);
- maintenance costs minimized;
- modularity of the system ( increase the size is enough to increase the number of modules).
A standard photovoltaic system connected to the network consists of the components shown in the diagram above.
The functions of the devices shown are:
- photovoltaic modules, an essential element of the system, capture the solar radiation during the day and convert it into direct current electricity;
- 's inverter, converts the electricity from direct current to alternating current, making it suitable to the needs of common electrical appliances (lamps, appliances, power supplies, computer ... )
- energy meters are devices that are used to control and account for the amount of electricity produced and exchanged with the network.
A photovoltaic system must be installed with the surfaces of the panels facing south. Installations with exposure to the south-east or south-west are allowed, providing that, once operational, the plant has a slight loss in productivity compared to the solution with optimal exposure.
Regarding the inclination of the panels, the inclination of 30 degrees from the plane in Italy is one that allows for maximum annual energy output. In this case, the impact of a different angle on the power plant's production is less, for example, if contained within + / - 10 degrees can be neglected.
Among the various solutions that the customer can choose to install a photovoltaic system, the choice of integration architecture deputy building to accommodate the system allows for an increase in the incentive State into account energy, as well as a pleasant aesthetic effect.
