Photovoltaics on roofs up to 10 KWp for individuals and small businesses:

The "Photovoltaics on Roofs" program is the most favorable and safest investment currently in Greece. It is possible to get up to 18% return on your money instead of the 3% deposit rate. The sale price of the kilowatt hour is 55 cents, an extremely generous price, which is guaranteed for 25 years. PPC buys the electricity you produce at a price of privilege for 25 years tax-free and with simple procedures!

Here are some common questions about the photovoltaic installation on the roof:


1. Who is egible to install photovoltaics in buildings?

It is for home consumers and small businesses willing to install up to 10 kW photovoltaics on the roof or roof of a building, including verandas. To be part of the program, they must own the space where the PV system is installed.


2. What does "small business" actually mean?

A small business employs up to 10 people and has a turnover of up to € 2 million annually. Is the program valid throughout the country? Unfortunately, the first phase of the program applies only to the mainland network and to those islands interconnected to this network (eg Euboea, Ionian Islands, Sporades, Argosaronic islands). The so-called non-interconnected islands (Crete, Dodecanese, Cyclades, NE Aegean islands) are currently excluded. Those networks will be included in the program once it has been determined how much additional photovoltaic power can be installed on each island.


3. I live in an apartment building. Can I install photovoltaic?

Yes. In the case of a photovoltaic system in a shared or shared building (terrace) one single system may be installed with the following conditions being fulfilled: either the other owners declare that they agree in writing, or the photovoltaic would be installed on behalf of all the owners (in which case the manager of the building is the official representative). If the terrace is shared and the owners of this place are willing to concede it to another owner of the building who has no rights to the terrace, they are able to act so. If the system is installed on a roof terrace apartment, obviously more systems could fit into an apartment building.


4. Will I sell all the solar power which is produced to PPC or just the excess?

All the electricity generated by the photovoltaic is chanelled to the electricity grid and you are paid for it with 55 cents per kilowatt hour (0.55 euro / kWh), a price guaranteed for 25 years. You continue to buy electricity from PPC and pay for it at the price you pay today (about 10-12 cents per kilowatt hour). This means that PPC will install a new meter to record the energy produced. If, for example, in the two-month period your photovoltaic generates electricity worth 250 euros and consumes 100 euros, you will receive a credit account of 150 euros, an amount that PPC will deposit into your bank account.


5. What are the conditions for joining the incentive regime?

There are three conditions:

· To own a PPC meter in your name (or on the shared account of the apartment building if the collective installation is selected).

· If you are a home consumer, you should cover part of your hot water needs from renewable energy sources (eg solar water heater, biomass, geothermal heat pump).

·If you are a business, you should not have received any other photovoltaic subsidies from national or community programs.


6. If I am a home consumer, should I have books at the tax office?

No. The home solar power generator is no longer considered a trade, in other words it is exempted from opening books at the tax office. As stated in the relevant ministerial decision, "there are no tax obligations for the photovoltaic system owner who distributes this energy to the grid". In other words, any income you make from selling your energy is not taxed. Under current tax law, you are also entitled to income tax deduction (deducting 20% of photovoltaic installation costs and up to € 700 per system).


7. Does the tax exemption also apply to small businesses?

Yes, provided the earnings are shown in a special tax-free reserve account. In case of distribution or capitalization of them, the current tax on the profits distributed is applicable.


8. Is a special permit needed?

No, the recent approval of small-scale work has been abolished by a recent ministerial decision. You only need to notify your Network Administrator or other vendor.


9. Are there any conditions to be met?

Photovoltaics may not be placed above the terminals of the stairway, lift shaft and any other construction. The layout of photovoltaic modules should not create a space for main or auxiliary use or semi-outdoor. In case of placement of photovoltaics on existing roofs, it should be within the roof volume following their inclination and half a meter away from its outline. If the photovoltaics are mounted on the house roof, the distance of the system should be half (0.5) meters inside for safety reasons.


10. What steps should I take?

a. Contact us to help you decide what system you should choose and how it will be installed.

b. With our help, you will apply to PPC to receive a connection offer (how much the new meter costs and how much the connection will eventually cost).


11. Can I install the photovoltaic system myself?

If you are a professional electrician and have been properly trained, yes. In other terms, don't think about it! According to the applicable regulations, a responsible engineering statement is required for the entire installation and therefore you should also consult specialized companies.


12. How much space will be needed?

First of all, the space should be unshadowed and, if possible, the photovoltaics should be facing the South and have a slope of about 30 degrees. If this is not the case (that is, if your roof is shaded or its orientation is not south), your photovoltaic will have a poor performance, without necessarily implying that your investment is not financially viable. How many square meters you need depends on the installation site (roof or sloping roof) and the photovoltaic technology you choose. In a house roof, for example, you will need roughly about 12-15 square meters per kilowatt, while in a tiled roof 7-10 sq. M. The company that supplies you with the equipment will calculate exactly the space you need.


13. Indicative photovoltaic performance in various inclines and orientations

South-facing and at an optimum tilt will get 100% efficiency, while horizontal positioning 90%


14. Will my roof bear the weight of photovoltaics?

The average weight of the photovoltaic with the stand is about 20-25 kg per square meter. Therefore, presumably there is no problem, especially in newly built buildings, since the roof is designed to withstand much greater loads. In any case, however, there will be a check on the static adequacy of the roof.


15. Will I need to tamper with the roof insulation to install the photovoltaic?

Usually not. However, even if the roof's thermal insulation or waterproofing needs to be injured in order to mount the photovoltaic mounts, restoration work is always done, so there is no problem.


16. Can my roof be overheated due to photovoltaics?

No, because photovoltaics do not "shed" the surrounding radiation, but they use the radiation that would fall on the surface anyway. In order to absorb as much sunlight as possible, the photovoltaic panels have a dark surface, which is even covered by a reflective layer to trap the sun's radiation. Thanks to this anti-reflective surface, photovoltaics do not "glaze" and we have reduced reflection phenomena that could sometimes be annoying. As measurements have shown, photovoltaics "shine" less than cars when solar radiation falls on them. The consequence of the dark surface is, of course, that the temperature of the photovoltaic panel increases in comparison to the the ambient air. So what about this heat? It obviously diffuses into the environment. The immediate next question is whether this heat leaving the panels could significantly increase the ambient temperature especially on a roof. This is not the case for the simple reason that the mass of the air is practically infinite compared to the mass of the photovoltaic and it is impossible to raise the air temperature at some distance from the panels. In fact, just 1-2 cm from the surface of the frames, the temperature is the ambient temperature. After all, between the photovoltaic and the roof there is a gap for the air to pass through, cooling the photovoltaic system (which, in turn, increases its efficiency). Interestingly, the temperature of the roof just below the photovoltaic panels is lower than the temperature of the uncovered roof. On a hot summer day with apnea, the room temperature below the photovoltaic can be as much as 13 degrees lower than if the sun hit the roof directly. In other words, the top floor of a building suffers less from the heat.


17. Photovoltaic shade roof temperature

Can I combine photovoltaic with green roof? Certainly yes. In this case, there are multiple benefits. The green roof cools the photovoltaic and increases its efficiency, while the photovoltaic prevents rapid evaporation and requires less water for the green roof. In addition, measurements have shown that the biodiversity of green roofs in photovoltaic shading areas is increasing.


18. Can I install photovoltaics on a building facade?

If you're a home consumer, no. If you have a business you can not only join the special program for the buildings we are describing, but also receive the aid scheme provided by Laws 3468/06 and 3734/09. Under these laws, up to 20 kilowatts (KWp) do not require authorization, and the electricity produced could be sold to HTSO for € 0.45 / kWh, which is guaranteed for a period of twenty years.


19. What equipment is needed?

A photovoltaic system consists of the photovoltaic modules (a photovoltaic generator resting on a metal mount) and the inverter that converts the direct current produced by the photovoltaics to alternating current of the same quality. This current passes through a meter and is chanelled to the grid.


20. How many kilowatts do I need for my home?

Since you sell all the power generated on the grid and continue to buy from PPC, this question makes no sense. How many kilowatts you put in depends on only two factors:

· How big is your roof, and

· how much money you want to spend.


21. How much energy does a photovoltaic produce?

The production of electricity from the sun is extremely predictable. What's interesting is how many kilowatt hours your system will give you annually. Generally, a photovoltaic system in Greece generates an average of about 1,150-1,450 kWh per year installed kWh (KWh / KWp per year). Obviously in the southern and sunny areas of the country a photovoltaic generates more solar electricity than in the north.


22. How much money is needed?

It depends on what system you install as well as the location. Roughly, a photovoltaic costs as much as a car (eg a 2 kW photovoltaic costs as much as a cheap small car, while a larger system of 5-10 kW as a large car). Whereas, the car is a constant expenditure for the next few years, the photovoltaic systems, on the other hand, has a return on the investment. profits. While the car will hardly functioning in the decade, the photovoltaic system will endure and bring you profits for over 25 years. Unlike most of the products and services we consume, the cost of photovoltaics is falling over time. The new legislation encourages you to, in any case, depreciate your system and make a reasonable profit. There is no need to put the whole amount out of your pocket. You can cover only a small part of the expense and the rest can be covered by a bank loan. In any case, the returns you get from installing photovoltaics will be better than if you put that money into a forward-looking account or invested in bonds or stock markets. And consider that these returns are stable and guaranteed for 25 years!


23. What is the environmental benefit?

Every kilowatt-hour produced by photovoltaics, and therefore not by conventional polluting fuels, avoids the release of approximately one kilogram of carbon dioxide into the atmosphere. A typical one-kilowatt photovoltaic system prevents 1.3 tonnes of carbon dioxide emissions annually, meaning that it would absorb the same amount that two acres of forest would. In addition, it results in less emissions of other hazardous pollutants (such as suspended microparticles, nitrogen oxides, sulfur compounds, etc.). Carbon dioxide emissions trigger global warming and change the Earth's climate, while air pollution has serious health and environmental implications.
