In Greece, there are residences where the use of a smart energy autonomy system and a series of smart devices can reduce the cost of household electricity by approximately € 800 on an annual base – a percentage of over 90%.

The cost of electricity in businesses can be reduced accordingly, from € 5,850 to just under € 200 per year, while emissions of CO2 can be lowered by more than 50 tons per year.

The Greek energy group EUNICE ENERGY GROUP – the first market player to implement ideas of the future – has already started to roll out the Aftonomo system in homes and businesses in both urban areas and rural regions of the country with absolute success, utilizing its experience in the design, development and operation of autonomy systems and applying cutting-edge technologies.

The EEG Group has gained worldwide recognition by implementing the only operating project for the production, storage and intelligent management of energy from wind and sun in the island of Tilos. It will soon expand its technological innovation to four (4) more islands in the Aegean Sea: Anafi, Donoussa, Leros and Fourni Korseon.

Aftonomo is the innovative integrated energy autonomy and independency solution developed by the Greek EUNICE ENERGY GROUP (EEG) in collaboration with JOLT.

It finds perfect application in the “Exoikonomo-Aftonomo” (“Saving and Autonomy”) program, which comes as a successor to the successful “Exoikonomisi kat’ Oikon” (“Saving at Home”) programs, but also as the first big step to combine energy upgrading with the energy autonomy of buildings.

Property owners and technical consulting engineers are called upon to follow and lead developments in the new European reality, which goes beyond conventional methods and classical energy interventions, ensuring not only energy savings but also maximized use of RES energy. By providing citizens at the same time with access to modern technologies that improve their daily lives, they can drastically reduce the costs of their energy needs, whilst obtaining energy autonomy and independence.

Aftonomo, the solution for homes and businesses offered by the EUNICE ENERGY GROUP, consists of RES power generation systems, an electricity storage system, smart chargers for electric vehicles, and smart devices and applications that allow the user to control and manage the electricity produced and consumed. For more information about Aftonomo by EUNICE ENERGY GROUP, the smart system for energy autonomy & independence, visit our official website www.aftonomo.gr

With Aftonomo by EUNICE ENERGY GROUP, homes and businesses have been equipped with photovoltaic roof systems, lithium battery storage systems and three-phase hybrid inverters. The equipment is complemented by the intelligent energy management system, which through the smartphone app and a range of smart meters and smart switches can be used to manage the distribution of the produced energy to the load, the storage system and the network, to program loads, and to adjust consumption levels, so that the needs for electricity are met by self-production to the maximum extent.

  

Aftonomo- Dimensioning platform for engineers.

Calculations and dimensioning of the Aftonomo system can be done quickly and easily by engineers, through the platform developed by the EUNICE ENERGY GROUP.

After a simple registration procedure, engineers can enter basic data and components of the installation of a residence into the platform, and directly receive the calculation results for a complete Afonomo system, which they can suggest and proceed to install at their client’s residence. This includes:

  • the number of photovoltaic panels and the power to be installed
  • the number and type of inverters of the system
  • battery capacity
  • support systems to be used for the entire installation
  • the results for annual money savings and pollutant reduction (CO2)
  • indicative system cost

By using this tool, installers can quickly and easily get results for an integrated energy autonomy solution to suggest to their clients.

EUNICE ENERGY GROUP’s dimensioning platform is offered to installers free of charge through the link https://mixanikos.aftonomo.gr/, through the EUNICE ENERGY GROUP website https://bit.ly/3mxVE2e or via the official Aftonomo webpage https://aftonomo.eunice-group.com/.

Smart energy management – JOLT system.

The Aftonomo system by EUNICE ENERGY GROUP is fully compatible with JOLT, the integrated solution for smart energy management and saving for businesses and residences. JOLT includes a wide range of smart devices and applications that allow the user to control and manage the electricity they produce and consume. More specifically, it uses smart meters to record and monitor consumption in real time, while loads can be controlled by smart remote switches and smart plugs.

Examples of energy autonomy and savings.

Example of operation of the Aftonomo system by EUNICE ENERGY GROUP in a residence: In this house, photovoltaic panels have been installed with a total power of 3.3 kW, together with a 5.8 kWh lithium battery, one (1) smart meter to record the total electricity demand, and one (1) smart switch controlling the electric water heater. The annual consumption amounted to approx. 4500 kWh. Electricity costs for the entire year amounted to 25 €. For the same consumption without the Aftonomo system, the user would have paid 790 € (based on the price list of the main provider). Therefore, the reduction achieved in electricity cost amounted to 96%.

The benefits of the Aftonomo system by EUNICE ENERGY GROUP extend beyond the reduction in electricity costs, considering that the self-producing system generates all necessary energy from green recources, eliminating the annual CO2 emissions for the electricity supply, which for the residence of our example would have amounted to approx. 10 tonnes per year.

Example of operation of the Aftonomo system by EUNICE ENERGY GROUP (EEG) in a business setting: In a business with an annual consumption of about 30,000 kWh, with the Aftonomo system by EUNICE ENERGY GROUP, including a 20kW photovoltaic system with a production-demand synchronization rate of 70%, almost 25kWh storage capacity, intelligent energy management system and a range of smart devices, energy costs are reduced from € 5,850 to just under € 200 per year, while emissions are lowered by more than 50 tons per year.

 

Comparative benefits of the Aftonomo system by EUNICE ENERGY GROUP in relation to simple energy clearing systems:

For the residence of the above example, if a simple net metering system had been chosen, i.e. without the battery and smart energy management options offered by the Aftonomo system by EUNICE ENERGY GROUP, annual electricity costs would amount to approx. 150 €. That is 6 times more, without ensuring the user any independence from the electricity network, and without protection from tariff adjustments by the energy supplier.

The Aftonomo system by EUNICE ENERGY GROUP also includes a smart charger for electric vehicles. This means that a user who opts for an electric vehicle will have the opportunity to recharge it for free with green energy produced at home or in the business, thereby eliminating fuel expenses.
