THE PHOTOVOLTAICA photovoltaic installation is an electrical system consists essentially of the assembly of PV modules, the required electrical component, such as cables and electronics that is the inverter, and possibly mechanical-automatic solar tracking.

INVERTER

The inverter is the heart of every photovoltaic system: it converts the DC of the PV modules into AC and feeds it into the public grid. There is no "best" inverter suitable for all uses, necessary to choose a power inverter adapted to that plant.

MONOCRYSTALLINE OR POLICRYSTALLINE

The efficiency of monocrystalline silicon

modules is around 14% - 16% and photovoltaic cells

are dark blue octagonal.

The efficiency of a polycrystalline module is

around to 12% - 14%, and the cells are deep blue square.

THE PHOTOVOLTAIC IN VENETO

Despite the return of any photovoltaic system is about average in Veneto has primacy. Over two thousand companies that have made sustainability their workhorse, with a total turnover of 21 billion.

INSTALLATION OF A PHOTOVOLTAIC

The installation of a photovoltaic system is not a complicated task but it is always better to make with a qualified technician.

Among the main aspects of the implementation phases of the system are: right size, installation mode, panel connections, connection to the network and testing.

PV modules' optimum angle is 30° throughout Italy.

SOLAR PANEL WITH ASBESTOS REMOVAL

A good idea for removal asbestos is photovoltaic installation. Italian law and its incentives have allowed a good outcome about this.

SOLAR IN LANDFILLThe area recovery can pass through renewable energy. Landfills and polluted soils have been made safe thanks to photovoltaic.

A perfect example of redevelopment and enhancement of an area is the Roncajette landfill. The photovoltaic installation generate 1000 kWp system.

THE COST OF A PHOTOVOLTAIC

The overall average price of a photovoltaic system ranges between 2,000 and 3,500 Euros per kWp and substantially depends on two variables:

• the size of the plant;

• the technology used (monocrystalline, polycrystalline or amorphous, other technologies ranging from "thin-film").

In Italy, the current PV market is no longer supported by the incentives of the Energy Bill, but thanks to the extension of the income tax deduction of 50% for solar photovoltaic installations made by December 31, 2014, to install a home is still very affordable

GSE: MANAGER ELECTRICAL SERVICES

Gestore dei Servizi energetici GSE S.p.A. is a italian corporation, controlled by Ministry of Economy and Finance, which provides economic incentives for the production electricity from renewable sources. It gives information to promote the energy culture and the sustainable use of it

THE OPTIMIZER ENERGY The Energy Optimizer is an "accumulator" of energy produced by

the photovoltaic system, or other power generators. The aim of Energy Optimizer is to make the end-user energy self-sufficient and completely independent of the Enel network, which the PV does not allow, eliminating once and for all the hateful energy bill.

WHY THERE IS LITTLE SOLAR INDUSTRY IN EUROPE?

Inspired by an article published in the May 26, 2014 Qualenergia.it.

Looking at the latest report from IHS on the largest producers of solar panels in the world, there is something striking: in the first 15 positions, there are not Germany, Italy neither Spain despite the opportunity offered, in recent years , from important incentives paid in Germany, Italy and Spain. .

No company in the countries that have paid most of the incentives for solar in the early years of the boom in this technology, has created a large industry sector. Sure, you say, the Chinese have made a clean sweep. But this is not so: in the first 15 places there are also three Japanese companies, two Americans, one Canadian and even a Norwegian.

SOLAR THERMAL Solar thermal systems are devices

that allow you to capture solar energy, store it and use it for the purpose of replacing the current water heating boilers fueled by natural gas.

Solar thermal systems are made up of panels that produce hot water using the sun's energy. Solar radiation heats a fluid that circulates inside the panels. This liquid transfers the absorbed heat to a storage tank of water. The use of the hot water accumulated in the tank, instead of water produced by a boiler or by a electric water heater, allows a saving on the consumption of gas or electricity.
