In this text we will refer to the most frequently asked questions photovoltaic our customers, but also on the answers we give, so as to help you to get easier decisions. 

Main points of the article: 

- Photovoltaics are a profitable investment.

-There are no major maintenance costs. 

-The law is flexible about the location of the installation. 

-The right choice for installers, does not spoil the insulation of the roof. 

-It's an investment that you need to do now. 

Renewable energy sources have penetrated the daily lives of the Greeks because of the conditions that have been developed mainly because of two factors. Initially, the consecutive price increases in the cost of power is one of the main problems faced by professionals. They are in a difficult position to decide if they will absorb part of the enhancement by reducing their profit. Or consider if you will move to price increases by losing part of their competitiveness.

The second reason why more and more people are turning to green energy is the debate around climate change. The problems arising from the ecological disaster, it is a problem that is expected to intensify in the coming years. One of the most direct ways of addressing the problem is the dependence on burning coal for electricity production. The combustion of lignite, is one of the principal reasons for the emission of pollutants responsible for global warming.

But it is perfectly logical to have any reservations for the transition to green energy. As had happened in the past and in all pioneer systems at the beginning of their operation. This article, therefore, aims to answer some of the basic questions that every person when called upon to decide whether you will put a solar system on the roof of the.

Frequently asked questions photovoltaic #1: In my best interest really?

The first thing you think of each professional is normal to the economic benefit it will receive from such an investment. Certainly the initial capital that is required cannot be considered a negligible quantity, mainly due to the fact that it needs to be paid on completion of the installation of the system. On the contrary, the existence of monthly electricity bill is able to give the feeling that it's less the amount required, but the reality is very different.

For example, a professional who needs a 20kW to fully cover the energy needs you will need to pay an amount in the range of 20.000€ to install a reliable photovoltaic system. If, however, remain in the existing form of power then, not counting the upcoming increases, will καλούταν to pay at least 400€ per month, which means that in 4 years I had already paid the amount of 20,000€.

If yes, calculate what you'll pay at the end of the εικοσιπενταετίας based on what is available right now in the energy market we come to the huge amount of 120.000€. It is easy to understand, therefore, how much profit has the professional that will be a self-producer of the energy needs for the needs of the business of the.

Frequently asked questions photovoltaic #2: What are the maintenance costs of a system

We are used to in every investment, there are the so-called small letters that reduce the cost of promised initially to the investor. It is logical, therefore, and the solar panels there is the search for that point which can create future costs and charges out of the program. Usually, the first thought of most of it focuses on the maintenance cost of the system, not at all unreasonable when we consider that it is a technological installation exposed to the weather.

The reality, however, is quite different, as well as photovoltaic systems have evolved to such an extent that the interventions that are needed after the installation is minimal. In particular, the panels are made with such specifications to withstand weather conditions over many years while the only exit maintenance, except for the cases that caused damage from hail, is an annual cleaning with water and common cleaning of the trade.

For the bases, respectively, the only care required is the tightness of the screws once a year for two years in order to get the system in its final form due to the contractions and expansions. Finally, the inverter does not need any care as long as it is within warranty but after five years or a decade, depending on the warranty offered by the supplier consists of a standard control.

Somehow this completes the admittedly short list of maintenance required for a photovoltaic system regardless of the size of it. Therefore, it is understood that there are virtually maintenance costs, as well as for most of the work does not require specialized workshop or multi-day tasks.

Frequently asked questions photovoltaic #3: How do we fit in the small roof of the business to me?

The progress of the technology of photovoltaics has led to a sharp increase in the performance of a system while maintaining the size of the installation is stable. A decade ago the solar panels that were predominantly on the market have a rated power of 220W and a little less than 2t.with an area of. Respectively in this present age, the power of each framework has more than doubled, reaching the 530W but without changing the size of the construction. Therefore, where a roof that can fit 20 panels once could set up a system to 4.4 kW, the system will be power of 10.6 kW.


Another factor that should be considered by professionals who are reluctant due to lack of space and the assistance provided through the law on the premises. More specifically, the current legislation allows you to place photovoltaic systems on the roofs and terraces of buildings, but not only. The system can be placed on the ground or on a roof accessory building or parking lot, while still allowed in the front of the building to be placed in the panel. With a few words, may be placed at any point desired by the professional with the only condition to this is a legally ανεγερμένο building or neat arbitrary.  

Frequently asked questions photovoltaic #4: you Will create a problem in the insulation of the roof?

One of the most widespread objections is found in the transition towards green energy terms how to install the panels on the roof or the roof and whether it will affect the insulation of the space. It is only reasonable that there is a particular concern as if it's not installed correctly can be a serious problem in the insulation of the building, both functional and aesthetic, and to require additional costs for correction.

Ο μόνος σίγουρος τρόπος για να αποφευχθεί το συγκεκριμένο πρόβλημα είναι η ανάθεση της εγκατάστασης του έργου σε εταιρείες που έχουν μεγάλη εμπειρία στο χώρο των φωτοβολταϊκών εγκαταστάσεων και η ποιότητα της δουλειάς τους μιλάει μέσω των έργων τους, όπως η ΙΩΝΙΚΗ Renewables. Μην διστάσετε, μάλιστα, να ζητήσετε να σας ξεναγήσουν σε κάποιες από τις φωτοβολταϊκές εγκαταστάσεις που έχουν ήδη πραγματοποιήσει ή να συνομιλήσετε με ανθρώπους που επέλεξαν στο παρελθόν την εταιρεία που επιλέγετε.

In addition, the most important mistake students interested in pv installations is the effort of saving some money through a selection of workshops that do not have the required experience in the installation of photovoltaic and as a result there are often problems. This has as a result of the installation costs are ultimately more expensive for the person that if he had, from the outset, trust-established in the field company because of the additional fixes that may be required.

Frequently asked questions photovoltaic #5: I Want to put photovoltaic, but let's wait a while

It is a very large number of entrepreneurs and household consumers understand the benefits of a photovoltaic system, but either because of cost or because of different priorities choose to defer the installation of the photovoltaic system for a different period. This, however, it has now been proven wrong choice, as well as the large increase in the number of new installations has led the network one step before the saturation.

The margins for new installations of renewable sources of energy are diminishing rapidly, having already, in many parts of the country begin to reject applications of photovoltaic parks. The reason for this saturation is that the energy produced by the solar panels should be transferred to the nearest substation in the network, and from there it is absorbed and distributed. The substation, however, has a maximum energy that can be absorbed and when you meet this limit, then the D.E.D.D.The.E stop accepting new applications of photovoltaics.

Therefore, the possibility to stop the issuance of new licenses, as was the case in 2012, it seems more visible than ever before without one can say for sure when it will reopen the system. So, the transfer of decision for the installation of photovoltaic can lead to inability to perform the installation when the idea has matured well in the mind of the person concerned, who will see their accounts to constantly grow. If, indeed, judging from the length of time it took after the 2012 to re-authorised permits for pv installations, it looks like one way to speed up decisions, and the procedures for those who want to take advantage of green energy.
