The easiest solution for anyone who is thinking of installing a photovoltaic system on the roof company is to ask for a free quote on a company specialized in solutions "turnkey", or directly contact the installing company, in both cases the customer is followed at all stages: design, request authorization, installation, grid connection practices and practices for the request of the GSE incentives granted under the rules established by the Third Conto Energia.
- Technical inspection at the hands of the designer or the installation company and communication of the budget;
- Acceptance of the quotation and the beginning of the authorization process;
- Presentation of the Wake (signaling certified logon) or Dia (commencement notice) depending on the size of the company and constraints in the area of municipal jurisdiction;
- Installation of the system and declaration of completion of work;
- Request from the connection to your electric service provider, specifying whether you want to opt for the metering mode or dedicated withdrawal;
- Request to GSE for obtaining the incentives available.
Convenience and choice of the
Thanks to incentives, today install a photovoltaic system is always convenient in terms of financial and environmental benefits, although from 1 January 2011 will expire the greatest benefits provided by the Energy Bill 2007-2013 for the entry into force of the new Regulation 2011-2013 .
The current incentive schemes, in fact, most are paid to the plants that are fully integrated on the roof. Slightly lower, however, are the incentives awarded to partially integrated plants, while much lower ones are reserved for isolated systems installed on the ground.
With the new Conto Energia therefore, integrated systems do not benefit from the same incentives in operation until the end of the year 2010.
Investment: how, where and with whom?
The company or entity concerned may decide whether to pay all at once, or apply for a mortgage to the banks. In the case of companies, in addition to traditional forms of financing (with the guarantee given by the incentives that will be obtained by the GSE), there are also specific products leasing.
In practice, for a request for a 100 kWp photovoltaic system, the cost of 500,000 € and a duration of 40 years, taking advantage of funding for the installation, the annual income would be € 50,000. In this way, in 15 years ripagherebbero the installments of the loan, redeeming the entire structure. The next five years, ie until all the aid given by the Energy Account and the incentive state, the plant will make, every year, 50,000 Euros. After completing his incentives, the plant will continue to produce energy that will be sold to the grid continuing to make.
For companies there is an additional benefit in the installation of photovoltaic systems on the roof. They are in fact provides additional incentives of 5% for the person replacing asbestos with photovoltaic panels. An example? In the case of replacement of the roof of a warehouse of 2,000 sqm, the cost would be € 70,000. Choosing a plant from 500,000 Euros, thanks to the incentive state, the energy produced makes € 50,000 per year, enough to pay off the loan in 20 years, without actually having paid nothing for the replacement of asbestos.
During periods of closure of the company or institution, the system must continue their exercise as energy is not absorbed by the user, however it is fed into the grid and then sold.
That said, there are no special requirements for maintenance of photovoltaic plants, in spite of this it is recommended that an agreement with the installer chosen in order to check the proper functioning of the cells and clean up once a year: more cells are clean, more will be efficiency in the capture sunlight and convert it into electricity.
How will the time of the decision at the time of commissioning the plant? On average 8-9 months, counting the bureaucratic process to start the permitting procedures and possibly the demand for more extensive evaluations, depending on the geographical location of the company.
