#1. What does the amount of the subsidy depend on?

• It depends on the size of the photovoltaic system. This is calculated as the power of the panel times the number of panels. Power above 7 kW is sufficient for the maximum subsidy amount.
• It depends on the electricity consumption for the last billing period, or the last 12 months. Consumption above 7000 kW is sufficient for the maximum subsidy amount.
• It depends on the location of the installation. The whole of Slovakia is divided. Some areas with deteriorated air quality belong to the so-called ORKO area (e.g. the entire city of Prešov). In the ORKO area, the subsidy is 575 euros per kilowatt. (normally it is 500 euros per kilowatt) A maximum of 7 kilowatts is subsidized. So the maximum subsidy in an ordinary area is 3500 euros, in the ORKO area 4025 euros.

#2. What will the cost be if I decide to install solar panels?

• You will be charged the price for the panel, plus the price for the construction, plus the price for the installation. But everything is possible

#3. Can a virtual battery provide me with a service so that I can use as much energy in the winter as I saved in the summer?

• It's a bit of a myth or a marketing ploy. A virtual battery is actually a deal between you and your energy consumer. A virtual battery is specifically the name of a product from VSE. And the name has become somewhat popular, like "sneakers" is the name for sports shoes.

Many companies offer a "virtual battery" and each has slightly different conditions. In the end, the electricity trading company always buys the electricity from you, which you supply to the public grid. And thus, it takes on the so-called "responsibility for deviation" for you, which is now an obligation, you must have assumed responsibility for the deviation before putting your source into operation. For you, it is a benefit in one way or another. The electricity trader guarantees that he will buy the electricity from you, and so everything you supply to the public grid brings you a certain discount on the total electricity consumption of your household.

#4. How can I save on energy production that I don't use? Do I have to pay for excess energy?

You will earn the most from the energy you produce if you also use it in your household. So if you stored the surplus in a physical battery and extracted energy from it late in the evening, you could reach zero household consumption with the optimal settings. Plus, if you produced even more and simultaneously supplied it to the grid, someone would still pay you for your electricity at the end of the day. However, physical batteries are currently still quite expensive, if you want to supply a lot to the grid - a larger photovoltaic system costs more. You will use your investment in photovoltaics most effectively if you set it up as efficiently as possible for your electricity consumption, the spatial possibilities of the roof and also the financial situation of the household itself. You can find more information in the "Utilization" section.
