now is the time to turn your house in a green building
Photovoltaic (PV) electricity generation (i.e. solar cells) is one of the most promising renewable During the last decade the PV industry has grown more than 40% per year.
Along with the PV module production the amount of installed PV power around the world has increased accordingly. In the end of 2012 the global cumulative installed grid connected capacity was at least 97 GW
The rapid decrease in cost of PV systems in recent years has helped to boost the yearly installed capacity.
A photovoltaic (PV) plant transforms directly and instantaneously solar energy into electrical energy without using any fuels.
A residential PV power system enables a homeowner to generate some or all of their daily electrical energy demand on their own roof, exchanging daytime excess power for future energy needs
The main advantages of photovoltaic (PV) plants can be summarized as follows:
- distributed generation where needed;
- no emission of polluting materials;
- saving of fossil fuels;
- reliability of the plants since they do not have moving parts (useful life usually over 25 years);
- reduced operating and maintenance costs;
- system modularity to increase the plant power according to the real requirements of users.
The main applications of residential PV plants are:
- Stand-alone installations (with storage systems) for users isolated from the grid;
- On-grid installations for users connected to the LV grid;
Feed-in Tariff incentives will help homeowner to increase their pv plant or will help to building a new one.
