Survey Digital entered the market of advanced power electronics in early 2009, acting as Satcon’s authorized distributor for Greece, Bulgaria and Cyprus. The company originally was re-selling photovoltaic inverters but was evolved later as a photovoltaic developer and named SDL Solar LLC, focusing in the markets of Greece, Bulgaria, Italy and the USA. Through the development of a project and its sale to an investor with financing, SDL Solar was securing the sale of the inverter system as well. But in order to convince a customer to accept the purchase of an inverter system, a local after sales support mechanism had to be in place. So back then, Survey Digital financed and instituted a technical team to commission and technically support the inverters sold to the investors/owners of the photovoltaic projects. These service engineers received training on central inverter troubleshooting in 2009 and begun commissioning central inverters in early 2010 and until the end of 2012. With the commissioning of dozens of MWs of systems, the team gained extreme experience and knowledge on advanced power electronics troubleshooting. In simple words, while others were “installing” systems, our engineers were providing “troubleshooting” on those systems. SDL Solar ceased business as a distributor of inverters and photovoltaic developer in October 2012, as the EPC market was coming to an end. At that time, one of the SDL partners Dr. Kostas Daniilidis believed that next professional success will come from exploiting and transforming the experienced inverter service team from a “tool for sales” as the new “core business”. So in November 2012 he personally founded and financed Survey Digital SP.LLC (M.EPE).

Vision: As the solar energy market in the Balkans has reached to a significant installed base, there is a tremendous need for professional after sales support of operating photovoltaic projects. We at Survey Digital, having our own expertise through self-own solar installations as well as experts in power electronics of utility scale solar installations over the past years, we aim to contribute to this task, through highly professional and experienced personnel. Mission: Our mission is to “keep inverters constantly on line”, as well as to have “power at its peak” in solar installations we operate and maintain. All these can be realized thanks to professional preventive maintenance tasks. And in rare cases of faults, we aim to bring the systems immediately back on line.
