About Survey Digital

Survey Digital has a long history in PV business, active since 2006 in development, engineering, procurement, construction, project management, after sales technical support of inverters and SCADA systems, as well as O&M for utility scale solar installations.

Since 2006, Survey Digital has developed hundreds of MWs of solar projects in Greece, Italy, Bulgaria, USA and Lebanon.

Since 2008, Survey Digital has provided engineering, procurement, construction, commissioning and project management for 50MWs of solar parks in Greece, Mauritania, Lebanon and Eritrea.

Since 2009, Survey Digital has procured and commissioned dozens of MWs of solar inverter systems. Therefore, Survey Digital’s personnel has a huge experience in advanced power electronics and photovoltaic systems advanced troubleshooting and is comprised of highly qualified and experienced in-house engineers.

Since 2012, Survey Digital is providing O&M services for a portfolio of 200MW in Europe and the Middle East.

Survey Digital has a significant heads-up on photovoltaic inverters expertise than any other technical company in the market, as it has always focused on “inverter troubleshooting”, rather than “inverter installations”. Because of that fact, Survey Digital is already selected by 8 major inverter manufacturers (Sungrow-China, Satcon/Greatwall-China, Power-One-USA, ABB-Greece, Fronius-Austria, Bonfiglioli-Italy, Santerno-Italy, SMA-Germany) to act as a local service provider for hotline, preventive and corrective maintenance services and procurement of systems and spare parts in the EMEA region. In addition, Survey Digital is selected to provide technical support for Also Energy and Skytron systems in EMEA, the top SCADA/monitoring company in the world.

Survey Digital financials are proven viable and sustainable over the years. The company has zero debt, a rich infrastructure and a profitable business plan. As a result, Survey Digital has been approved by Alpha Bank Greece for financing for its operations in September 2014, proven bankable.

Survey Digital is selected by major IPPs, EPC and O&M companies to work with in the region of Europe, North Africa and the Middle East.

Who Is Survey Digital

Survey Digital entered the solar market in 2006, providing consultancy services to private investors in order to fully permit and develop utility scale solar installations. The company provided the full package of studies and support (production licenses, environmental approvals, installation & operation licenses, financing, EU subsidies, EPC consultancy, etc.).

In early 2009, Survey Digital entered the market of advanced power electronics, 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, the company was securing the sale of PV systems as well. But in order to convince a customer to accept the purchase of a PV system, a local after sales technical support mechanism had to be in place. So back then, the company financed and instituted a technical team to commission and technically support the systems sold to the investors/owners of the photovoltaic projects. These service engineers received training on central inverter troubleshooting in 2009 and today they consist one of the greatest teams available for inverter manufacturers and act as their service mechanism in the EMEA region.

After 2015, Survey Digital started providing construction and commissioning services for a projects in Africa and the Middle East, installing successfully a portfolio of hybrid PV projects in Mauritania, Lebanon and Eritrea.

Lastly, after 2017 Survey Digital developed a portfolio of more than 100MW in Lebanon and Greece.

Survey Digital is a company expert in all photovoltaic projects stages, having successfully provided permitting of licenses, consultancy, development, financing, purchase and sale of solar SPVs, engineering, procurement, construction, construction oversee for other EPCs, operation and maintenance of utility scale solar projects globally.

The company has the following business units:

  • Development of photovoltaic projects
  • EPC for photovoltaic projects/Construction oversee and project management
  • Operation & Maintenance of utility scale photovoltaic systems
  • Service partner of photovoltaic systems manufacturers

Vision: As the global society has agreed in 2015 in Paris to reduce the carbon emissions and delay the climate change, there will be a constant need and rising trend for many solar energy projects to be developed and grid connected around the globe. The 540GW mark at a global level could be reached by 2020. A significant market is the one in Europe, having already installed dozens of GW of solar projects. These projects will be operating for decades and in the meantime, the emerging markets of Middle East and North Africa provide a huge need for solar experts to provide all kind of services in the solar business. Survey Digital, with more than a decade of experience in utility scale photovoltaic projects, aims to contribute to this task and to support this effort with the most professional way.

Mission: Our mission is to support our partners and our clients to install and operate as many solar projects within the EMEA region. In that way, local communities and people will enjoy clean and affordable energy, reducing our carbon footprint and preserving our physical wealth. This can be realized due to our professional approach on the business, which is based not only on our scientific background but also on our huge experience over the past decade.

Values & Code of Ethics: The need for change in the energy industry is coupled by the need for change in business practices and social responsibility. That is why Survey Digital’s values and code of ethics follow a “Clean energy promoted by clean business practices” approach. Survey Digital’s business customs and processes promote efficiency, honesty, integrity, transparency and loyalty to our partners and society, in the utmost professional and efficient manner. We also aim to be a socially and environmentally responsible organization, implementing green practices under our Corporate Social Responsibility policy. This policy looks to make our staff feel loyal and proud of being part of the Survey Digital team, while we help bring about real changes to human lives and to society.

We are always in search of new colleagues for our growing team, people that have the ambition to become solar experts and provide professional services to the solar industry. We are an international company, therefore all candidates need to know fluent English, advanced computer and network skills and understanding of electrical/electronic phenomena. Most important though is for the candidates to have the appetite to discover the secrets of the solar business. If you feel that you fit the description, please send us your resume.
