Delta Solar PV Systems Installed in Belgium

By Delta on March 21st, 2016

Belgium ‘Middelkerke’ invested in Delta’s solar PV systems to reduce carbon emissions by more than 20% in order to decrease operating costs

Seventeen rooftop solar PV Systems have been installed in Belgium Middelkerke in order to reduce CO2 emissions by more than 20% to save on operating costs. As an experienced installer of solar PV projects in municipalities with additional long-term investment expertise, Ecorus was selected to provide a proposal for the feasibility, supply, design, installation and connection of a photovoltaic system for 17 buildings, selecting Delta reliable RPI inverters for the project.

The Middelkerke municipality, together in an association with eight other Belgium local authorities, became a signatory of the Convenant of Mayors. This European movement was established in 2008 by the European Commission with the aim for all its signatories to commit to cut CO2 emissions of their territories by at least 20% by 2020 and implement sustainable energy action plans within one year of their signing up. The signatories are made up of cities throughout the EU that vary in size from small villages to major metropolitan areas.


According to Ecorus, the Delta inverters were selected because of fast delivery and good experiences in the past with the units. Delta RPI inverters are indeed built to be robust and reliable and are ideal for rooftop commercial systems.  With their high peak efficiency up to 98.4%, the Delta solar inverters provide the city with a stable solar energy source giving high yield for many years.

An investment of 1 million euros was required for the project, with an estimated payback period of 8 years.  The solar PV Systems panels are expected to supply 20% of the electricity required in the related municipal buildings.  Therefore, it is considered a profitable investment, with the added benefit that it is completely self-funded by existing city budgets and future energy savings.

Construction of the solar PV systems project began on July 10, 2015. As part of the project, energy loss of all the city buildings was studied and a plan to reduce losses with additional insulation and digitizing of the heating systems was implemented. Insulation was strategically placed in boiler rooms and in roofs to minimize the building energy consumption.
