Three crystal grid inverter used in Hunan's first photovoltaic roof project


In mid-March, in Changde City, Hunan Province the Wuling Langzhou South Changde Yilida computer network limited liability company installed a small photovoltaic system in their company the roof. System installed capacity of 1.8kWp, and is composed of 10 180W polycrystalline silicon components and a new energy supplied by three crystal Sununo-TL3KB single MPPT inverter.

As the system is used to meet the daily electricity system installed capacity of small, so every day of the electricity used in basically all the company's office during the day electricity. The person in charge of the company, according to Mr. Zhang said, just before installed 10 component test, and if the result is good, and follow-up will increase the installed capacity of the system.

As of today, the system has been in operation for about 10 days. Although recent local weather overcast eyes uncertain, but in the the Sanjing new energy Webserver monitoring data can be seen as long as the weather is sunny, of this 1.8kWp PV solar panel small system day generating capacity can reach up to about 10 kWh. The electric hair every day this system can all be used to the office electricity during the day.

Mr. Zhang introduced the system Hunan Province's first used in office building small photovoltaic rooftop power generation projects. It is understood, Hunan radiation intensity and sunshine hours in the three regions, the average effective illumination time in about 4-5 hours daily photovoltaic power generation, theoretically 2kWp installed capacity hair about 8 kWh per day, for an ordinary family is basically to meet the daily demand for electricity.

There is no doubt that the successful application of the system will bring a good propaganda and call for the role, through the practice of the company, so that the surrounding more people are aware of photovoltaic solar module power generation is not only green but also can bring to local residents and businesses The sum of small gains. Relative to household and grid-connected photovoltaic systems, photovoltaic systems commercial value will be higher. Generally due to the company's peak during the day, the electricity generated by the PV system during the day just for the company office equipment electricity, excess electricity grid, which truly reflects the value of the photovoltaic power generation.

According to Italy's new national energy strategy, the Italian Revenue did not get the country's feed-in tariff subsidies off-grid photovoltaic power generation system will introduce a tax relief policy. Said in a statement released by the Italian small solar panels Energy Society Gruppo Imprese Fotovoltaiche Italiane (GIFI), PV systems installed from July 1, 2013, the budget does not exceed 48,000 euros, and will have access to 50% of the financial relief. This includes a system of net metering program.

PV systems installed in the June 26, 2013 to the 30th highest budget of 96,000 euros, will have the opportunity to get a 36% tax cut. The GIFI say very much welcome this decision of the Italian Revenue Agency.
