e-greeksolar Ltd participated at the Go 4.0 Green Crowdhackathon on 14-15 December 2019, organized by Ministry of Energy and Environment of Greece, supported by technology and innovation company Crowdpolicy. The solaris ++ team developed the "BIoT" platform (prototype), a cloud based application for transferring and storing data from smart devices and storing them in the platform in real time. In addition, a IoT-to-blockchain bridge application has been developed. The application (bridge) can store data from smart devices over a LORAWAN network on a blockchain (ethereum).

On the photovoltaic park DIMITRA II the region Kilkis, e-greeksolar Ltd realized a first pilot blockchain project.

The pilot project is dealing with connection and storing of smart-meter data to a permissioned blockchain network. The application demonstrates the ability to digitize production or consumption energy data, real-time visualization and monitoring. It also enables the transfer of data among members of the network in a secure and transparent way.

In Pefka, near to the city of Thessaloniki, e-greeksolar Ltd developed and constructed its first net-metering photovoltaic project. The residential pv-system has an installed capacity of 5kWp.

Net metering (self-consumption) is the direct consumption of locally generated energy from decentral energy resources (DER), usually photovoltaic, while the possible additional demand is covered from the Grid. Thus, the Grid is essentially used to store the energy produced. At the end of the measurement period the energy is consumed locally.
