Personal consultation

Once you have provided your details, we will contact you to arrange an appointment for an on-site consultation to assess which solar system would be right for you.

Getting a quote

Following the on-site survey, we will prepare a personalized contract offer for you based on your annual electricity consumption (taking into account any future electricity needs) and the characteristics of the particular building. Upon request, we offer several solutions, based on which you have the opportunity to choose the system that suits your needs. The offer includes all elements of the system (solar panel, inverter, support structure), the total cost of design, approval, and turnkey construction.


By signing the offer, you confirm your acceptance of the terms and conditions. If accepted, we will start the installation process after paying the first two sub-invoices (10% and 40%).

Household - sized power plant application

After the contract was signed by both parties and it came into effect, we will signal your need for a powerplant connection towards your Distribution Network Operator via submitting an application. This is the first step in the licensing process. The application indicates the capacity of the production equipment to be installed and under what internal network conditions (single-phase, two-phase, three-phase).

Planning, submission of accession documentation

After the approval of the application, we prepare the accession documentation. The connection documentation contains technical information and plans related to the design, protection and operation of the system. This documentation includes the connection statement, the single-line wiring diagram, and the producer's declaration.

Installing a solar system

Following the availability of the connection and technical-economic information accepted by the distribution licensee, our construction team will carry out the installation of the small solar power plant at the time agreed with you. The installation usually takes one business day.

Notification of Completion

After having finished the installation, the system should be reported ready to get the distribution licence so that the licenced distributor can make the necessary steps at the meeting point in order to be able to use the system.


Connecting to the network

After having been reported ready, your current meter will be replaced with a device that is able to measure both the consumption and produced energy by the local licenced distributor.


Under ideal circumstances, the solar panel is able to produce electricity for at least 20 years. Thanks to the development of material and solar technology, today's systems can be expected to work for 30-40 years. When the production starts, you can install a monitoring application to your device (smartphone, laptop) to follow the production of your small solar power plant. You can also track the current energy production, and get daily, weekly and monthly summaries about the amount of the produced energy.

Frequently Asked Questions

There are plenty of factors to consider. It depends on the energy use, the conditions of the installation (direction of the roof, shades) and the size of the system. But the average payback period is 8-15 years.

Under current legislation, according to the so-called saldo settlement, if the customer and the trader of electricity have agreed in the settlement, the customer can bill the excess electricity to their trader or universal service provider, who shall settle and pay it. Thus, income is generated for the customer. The income on the produced energy is taxable, therefore, income tax shall be paid on it.

It is important to note that the produced energy within the accounting period is charged at the gross electricity tariff up to the amount of consumption (until the amount of the produced and consumed energy are considered to be equal). The service provider shall pay for any excess energy produced over that amount at the average product price of the electricity sold under the power purchase contract. The tariffs may vary depending on service providers; thus, the power purchase contract shall apply in all cases.

Solar panels work best in direct sunlight, at right angles of incidence, and at low temperatures, but they are also able to produce energy in cloudy weather. Because solar panels operate at part load most of the time, today’s technologies pay special attention to optimal operation in this range.

That’s why it’s worth to conclude an annual billing contract with your service provider in case of a grid solar system. This way the surplus amount produced in the summer is taken over by the service provider, and there is no need to pay extra during the winter months, when there’s not enough power produced. 

Essential components of a solar system include solar modules / panels, associated special cables and connectors, an inverter, other electrical equipment such as surge protectors, switches, and finally a metal structure that secures the solar panels to the roof with its associated fittings.

This always depends on the power of the chosen solar panel, approximately for a 1 kWp system it means about 4 or 3 panels.

There are many cases where these two different devices are mixed or just thought to be equivalent. It is worth knowing that these two words have completely different meanings among renewable energy sources. The main difference between a solar collector and a solar cell is that the solar system generates electricity and the solar collector only heats water.

In terms of solar panel systems, there are standalone power systems (SAPS) and grid-connected systems.

In the case of SAPS systems, the produced excess energy is stored in batteries. If the system is not generating energy (e.g., when the weather is cloudy or at night), the required energy is provided by the batteries to the extent of the stored amount.

In case of grid connected systems, the produced excess energy (which is not used immediately) is fed to the grid. When there is no production, the customer buys energy from the grid. In such cases, a two-way meter is required and billing is done according to legislation. The majority of solar systems currently available on the market belong to this category, i.e. they are grid-connected.

A written permission from your local grid operator is needed to install a solar system. In this case, the specific design, technical data and documentation of the planned soral system shall be attached. A following condition is that the electricity grid must be able to receive the generated energy. We completely take over this licencing process from the customers (based on a corresponding power of attorney), and also provide full, up-to-date information on the licencing process. We would like to highlight that if the electricity grid needs to be upgraded, the customer is responsible for the emerging tasks and costs. In the case of listed buildings and condominiums, special permits are also required, which the customer shall obtain.

The tasks of the contractor and the licenced distributor are separable during the installation process of a solar system. E.ON Energy Solutions Kft. is responsible for the implementation, whereas the notifications to the licenced distributor are made uniformly to all of the licenced distributors. The licenced distributors are responsible for the tasks to be done at the metering point. They have uniform processes, with possible differences in lead times. E.ON Energy Solutions Kft. has no influence on the tasks of the licenced distributors.

Since E.ON Solar, as a dealer, does not differentiate between network service providers, the installation process is the same throughout Hungary. The administrative process is different in each service area, so the deadlines may differ for different network areas.

In Hungary, this value for a 1 kW solar system is between 1050 and 1250 kilowatt hours per year, based on the data of existing solar systems. At the same time, this data is greatly influenced by the orientation of the roof, the angle of inclination and the geographical position, roof shading. It is most effective with a south-facing installation.

Naturally, but it’s only possible, if after the installation of the solar system an electric boiler or individual electric heaters are used for heating.

About solar panels in general

What does a solar system consist of and how does it work?

  • One of the most important elements are the panels, which are ideally mounted on the roof with the help of an aluminum support structure. If there is not enough roof space, ground installation is also possible.
  • The direct current produced by the solar cells is converted by the inverter into the alternating current required for the operation of household appliances. In addition to its many protection functions, it provides connection to the power grid. For conventional type inverters, it is important that the roof surfaces accommodating the solar panels are uniform in angle and orientation and free from shading.
  • The current converted by the inverter passes through the bidirectional meter, which can measure both the electricity produced and the electricity used.
