Photovoltaic and Solar

  (The largest PV plant in Tolentino of Italy)





A photovoltaic system is essentially a set of components capable of converting radiation to electrical energy for domestic and industrialuse.

The system installed at the Hill Farm kingdom has a power of 9.80kW three-phase, obtained by means of 56 panels of 175 Wmonocrystalline silicon. The panels are to make the cover of a shed for car parking that occupies a floor area of approximately 70sqm, particular attention was paid to the choice of materials, in fact the main structure is made ​​of spruce wood in order to retrieve materials and sections other building components in the country resort.

The location was chosen in order to obtain the best orientation to the south-southeast and at the same time make it less visible from anywhere on the panels, only the rooms on the upper floor you can see them. The bottom at the time was essentially left to view for educational purposes as the accessibility of the system makes it easy destination for visitors, particularly schoolchildren, is expected to complete masking of the electrical connections and metal structure. This is a temporary arrangement, as all the solar panels,along with other planned solar thermal, will complement thecoverage of the renovation of the old accessory agricultural / barnfor an agriturismo.

The operation of the system is logged and monitored through digital displays present on all drives that communicate operating data: the power produced at the time, the energy produced during the day and the total from the date of activation, the output voltage from the panels and all operating parameters available for service engineers.
Obviously there are all the necessary electrical protection systems in accordance with the dictates of the Italian Electrotechnical Committee (IEC 11-20), to ensure the safety of all stakeholders; must not forget that you have to do with a real central production of electricity, although of limited power, directly connected to the electrical distribution lines, which then must provide the same security benefits of far greater power. And 'perhaps this was the technical challenge but most of the cultural past few years that has allowed us to introduce strict regulations to ensure proper functionality and safety of PV systems and has effectively rendered useless storage batteries, which were once the environmental achievements of these great contradiction.
In environmental terms, it is obvious that the annual production of electricity, 12,740 kWh and estimated that covers 90% of the consumption of the accommodation, allow a reduction in CO2 emissions equivalent to 9.7 t / year and NOx of 21 , 6 kg / year. The plant in question is one of the first achievements made possible by the mechanism of the so-called feed-in tariffs in Tariff (MAP Decree 28.7.2005 – application n.2127), through which the electricity produced is fed into the grid and sold to the Manager at a price about three times higher than the purchase price, for a period of 20 years.
Work began in June 2006 and were completed in December with the timing of routes dictated more bureaucratic than from the actual time required, the actual construction has in fact about two weeks of work. The electrical connection of the local SAMS took place February 16, 2007, the second anniversary of the Protocol Kjoto, and the plant is now operating regularly and produces electricity.

The construction was designed by engineer Charles Bianchini of Tolentino and the realization made ​​by TEA-alternative energy technologies as well of Tolentino, which was formed several yearsputting together different professional local and able to operate at360 ° in the design and implementation systems for energy efficiency intended for widespread application in small local companies.

The photovoltaic system is in fact only the first operation carried outat the Farm Hill Regnano are planned for a solar thermal hot waterand pool heating, and a geothermal system for heating the new premises. The geothermal probes have already been laid in partduring the execution of the work of excavation and in part will be completed in subsequent structure built, in particular, it will retrieve the stored heat from the pool in the summer to be able to exploit in the first phase of the cold season . The set of photovoltaic panels, solar thermal and geothermal will be able to make it almost self-sufficient from an energy standpoint the entire structure, the electricity produced will operate the geothermal heat pump with which you will warm up to new local.
