PHOTOVOLTAIC

What benefits can I get from a PV plant?

If you install a photovoltaic plant you become a clean energy producer, and this gives you important advantages because:

  • electricity from photovoltaic systems uses solar energy, which is a clean and renewable source. Installing solar modules allows to produce energy without CO2 emissions, in this way your house reduces its negative impact on environment and becomes sustainable.
  • photovoltaic technology has been widely tested, therefore it is safe and reliable. It is also particularly promising because in countries like Italy, with high levels of sunlight, it has huge potential
  • it helps you cut the cost of your bills because you can consume the energy you produce.

Is there any economic return?

PV plants are also convenient from an economic point of view. You produce the energy that you need and you do not depend on energy suppliers; you do not suffer from any increases in electricity price and you can inject your surplus electricity into the grid thus gaining additional profits for over 20 years. It is worth reminding that the energy you withdraw from the grid is burdened by taxes, system charges, network and measurement services, which altogether account for about 46% of a kWh cost (respectively 12%, 19% and 15% of the final cost), whereas all this disappears with self-production.

Producing your own energy is proving to be an excellent economic opportunity even without incentives.

Thanks to 9REN you can also benefit from several solutions aimed at reducing your energy consumption and cut the cost of your bills, through energy efficiency services specifically designed for your home.

Can I get any funding for purchasing a photovoltaic plant?

With 9REN you can obtain loans at special interest rates to buy a PV system, with the advantage of having a single interlocutor, who takes care of all the administrative procedures for your funding, with no waste of time. A 9REN consultant will be available to show you the most suitable financial product designed for your needs.

What is a PV plant system like?

A photovoltaic plant is made of various elements:

  • PV modules: they are installed on rooftops and generally placed as to capture as much solar energy as possible. In a plant with an installed capacity of 3 kWp (usual capacity of a household system) modules occupy about 25 square meters. The surface of a photovoltaic system increases according to its capacity
  • Inverter: together with modules, it is the central element of a power plant, it transforms the direct current produced by PV panels into alternating current, suitable for domestic use. It is generally placed in the attic or in other accessible areas (cellar, garage, etc)
  • production meter: it is used to measure the energy produced by a photovoltaic plant
  • structures, conduits, electrical wires: necessary components to assemble a photovoltaic plant.

What shall I do to install a photovoltaic system on my rooftop?

If you decide to install a PV plant on your house rooftop, you won't have to worry about anything, because 9REN network of qualified partners will take care of all the installation process, from technical to administrative aspects:

  • 9REN partner will visit your home for a technical inspection, which is necessary to confirm – according to your type of roof- if it is possible to install a PV plant. He will explain you each step of the project and how your plant will be connected to the grid
  • within 45 days after signing the contract your plant will be installed and connected to the electricity grid. The cost of such activities is included in the price agreed for the project. The project estimate may change only in particular cases where additional works are required, and you will be informed during the technical inspection, in order to feel free to decide whether or not to proceed with the installation.

What documents do I need for 9REN inspection?

Before the visit of one of our partners, you will need to prepare the following documents, in order to allow a preliminary technical evaluation:

  • last electricity bill (which shows your annual consumption)
  • your ID card and tax code
  • IBAN (for crediting of incentive rates)
  • act of property
  • cadastral certificate
  • cadastral map
  • sections and perspective drawings of your house and roof, if available
  • certificate of your house energy efficiency class

You will be informed by 9REN partners in case you need to produce further documentation.

  • DIA/CIL or equivalent declarations required to start construction works
  • local distributor estimate
  • procedures to obtain incentive prices
  • funding procedures and documents

What you need to do is indicate in your tax declaration the income you obtain from the energy injected into the grid.

Shall I change my electricity meter?

Your electricity meter shall not be substituted, though it will be installed an additional one (production meter) to measure your PV plant’s production of electricity. Your local distributor will read it automatically. In this way an amount of money equivalent to the electric energy generated by your PV plant will be deducted from you bill. You won’t have to do anything to have your meter read.

Where does the material used to build the plant come from?

Solar panels used by 9REN are of excellent quality and have an extremely affordable price compared to the market average. We use high quality "made in Italy" products, with the warranty of Italian brands, and excellent non European products with very competitive prices, which pass the strictest quality tests within the market.

All products used to build your photovoltaic plant comply with the certifications required by law (IEC), which guarantee high performance in adverse weather conditions (snow, wind, hail, electrical overload, etc.).

What is the average lifetime of a plant?

A plant has a useful life of at least 20 years and can produce electric energy for up to 30 years. A plant’s production, at the same amount of sun exposure, is almost unchanged over time. In case of damage you can contact 9REN technical support at our toll free number 800 134 010 and you will get all the necessary assistance.

What kind of warranties are provided with a PV plant?

  • photovoltaic modules are guaranteed 10 years for manufacturing defects
  • inverter is guaranteed 10 years (5 years in usual market standards)
  • Warranty on PV modules performance covers 80% of the production up to a period of 25 years

In case you need to replace part of your PV plant or carry out its maintenance during plant’s useful life, all products covered by warranty will be replaced for free (manpower and transport costs included).

When signing the contract, you can also discuss with 9REN technician the opportunity of choosing the optional warranty "All Risk", which covers direct damages (theft/fire) and indirect damages (liability for third-party acts) to the plant. 9REN partners guarantee the disposal of end-of-life modules thanks to their membership with the national collection and recycling Consortium (Cobat).

What benefits and warranties does 9REN offer?

9REN is one of the leading operators in the photovoltaic market . {j}Its strength and soundness come from being not only a company producing and installing PV plants, but also one of the main investors in the renewable sector, who has build over 200MW PV plants and power stations owned by the Group and for third-parties.

ENERGY EFFICIENCY

What is energy efficiency?

Energy efficiency is the ratio between products and services and the amount of energy used to produce them. Our goals of energy efficiency and conservation can be achieved not only with technology but also with more responsible behaviors of end users. As soon as energy improvements are implemented, consumers’ economic benefits are immediately visible in bill savings; for some of these improvements, investment can be recovered in short-medium term, also with the help of national and local incentive measures.

Why be efficient?

Today energy is a problem concerning everyone. Continuous growth of energy demand leads to a higher depletion of natural resources and produces important effects on our planet’s health as well as on the entire world's population. Forecasts say that in 2100 world’s energy consumption will be tripled.

Just think that CO2 emissions and other greenhouse gases have increased by 25% over the last 150 years and that 44% of greenhouse gases is produced from residential, industrial and service sectors. In Europe buildings account for 42% of the final consumption, and according to Enea surveys in 2011 there were 69 million real estate units on the national territory. A massive use of more efficient technologies in the residential sector would make it possible to reduce consumption by up to 12% already in 2020, about 4 Mtoe less than the actual trend, which equals approximately 1.4 billion euros.

These numbers make us immediately understand the enormous potential of energy conservation that could be obtained from energy improvements within the residential sector. According to Enea surveys, the ratio between the energy bill’s annual cost for a class G building compared to a class A + building of the same size is 20 to 1.

What are the potential savings for a household?

Each 4 people household consumes about 1.8 toe (tons of oil equivalent) in a year for use of fuels and electricity. More than half of that is absorbed by heating consumption.

Consumption of a single electric kilowatt hour, which is about half an hour ignition of a water boiler or electric heater, requires burning about 250 grams of fuel oil and causes emission of 750 grams of carbon dioxide. A 4 people household, with a daily consumption of approximately 10 kWh, produces nearly 6 kg of CO2 in a day.

This example is enough to understand that reducing household energy consumption means at the same time paying less expensive bills and improving the environment quality.

Without any special sacrifices a household can reduce consumption and save up to 40% of the heating costs, with two types of improvements that can even enhance property:

  • building improvements to limit heat loss
  • improvements of the heating system to increase its efficiency and optimize its management.

A further 20% can be saved with appropriate choices regarding:

  • indoor lighting
  • electrical appliances.

REGULATIONS

Tax deductions for energy efficiency improvements

According to the Legislative Decree 63/2013, a 65% tax deduction is granted for expenses incurred from 6 June 2013 to 31 December 2013 to improve energy efficiency of existing buildings Costs incurred in a previous period benefit from a 55% deduction. From 1 January 2014 tax deduction will be 36%, the same that is currently applied to construction works.

The decree excludes from the 65% benefits those expenses incurred to replace heating systems with high efficiency heat pumps and low enthalpy geothermal plants and those to replace traditional water boilers with heat pump water boilers for domestic production. In addition, the same decree establishes that with regard to expenses incurred for improvements on common parts of buildings or that affect all the units comprised in a single building, the 65% deduction applies from 6 June 2013 to 30 June 2014.

What improvements can benefit from the 65% tax reduction?

The 65% tax deduction applies to expenses incurred and charged to taxpayers for:

  • energy requalification improvements of existing buildings, that get a value limit of annual primary energy requirements for winter heating, lower by at least 20% compared to values reported in a reference table (reference parameters are those defined by the Decree of the Ministry for Economic Development of 11 March 2008, as amended by the Decree of 26 January 2010). The maximum value of the deduction is EUR 100,000.
  • improvements of existing buildings, parts of existing buildings or residential units, regarding opaque vertical and horizontal structures (rooftops and floors), windows and fixtures, up to a maximum deduction of EUR 60,000. The basic condition to benefit from the incentive is to comply with thermal transmittance requirements, expressed in W/m2K, as listed in a reference table (transmittance values, in force from 2008, were defined by the Decree of the Ministry of Economic Development of 11 March 2008, as amended by the Decree of 26 January 2010). This group includes: replacement of entrance doors, on condition that such infixes separate the indoor heated space from outdoor space or unheated premises, and that thermal transmittance indexes required for window replacement are respected.
  • installation of solar panels to produce hot water for domestic or industrial uses and to fulfill the needs of hot water in swimming pools, sports facilities, housing and care homes, schools and universities. The maximum value of the deduction is EUR 60,000.
  • replacement of existing winter heating systems with more efficient condensing boilers and subsequent setting up of a distribution service. The maximum value of the deduction is EUR 30,000. The 63/2013 decree excludes from the 65% benefits those expenses incurred to replace heating systems with high efficiency heat pumps and low enthalpy geothermal plants and those to replace traditional water boilers with heat pump water boilers for domestic production.
