FROM FIELD EXPERIENCE
TO DIGITALISATION
01 / EXPERIENCE
Nearly two decades where solar plants are truly made — in the field, across construction interfaces, under real delivery pressure. That experience is now moving toward technical management, construction management and digitalisation.
02 / EVOLUTION
CAREER SPAN20072026
The same discipline, applied at a different altitude each time — from the ground up.
Electrician → Operator → Foreman
2007–2017Greece + international sites
A decade on the tools. Electrical installation work in Greece and on international sites, advancing from electrician to operator to foreman — the ground layer everything after it is built on.

02.2 / SIX STAGES
The progression behind the chronology — each stage built on the one beneath it, never replacing it. Every line names the verified role that evidences it.
Electrician, operator and foreman on site from 2007; Construction Foreman on Oriana I & II, Puerto Rico (2016).
Electrical Engineer / O&M Supervisor in the UK (2017–2018); Electrical Inspector on Delfini, 100 MWp (2023).
Technical Supervisor on Burnoye 2, Kazakhstan (2017) — training local contractor teams in PV construction methods.
Construction Manager at Raggio Solare (2020–2022) — schedules, client interface and electrical crews at a larger PV scale.
Site Manager on the Skovgaard hybrid PV site, Denmark (2022) and across the 17-project Metlen portfolio (2023–2025).
Technical Advisor on Skopos, 40 MWp, Florina (2026) — QA/QC, reporting, HSE coordination and project controls.
03 / INTERNATIONAL DELIVERY
Utility-scale solar. International delivery.
Field-led engineering.
SELECTED PROJECTS / CASE STUDIES
BRIDGING THE COMMUNICATION GAP.
Coordinating local construction teams across two utility-scale PV projects where communication itself became a critical part of project delivery.
BUILDING THE TEAM THAT BUILT THE PLANT.
Training local contractor teams to execute and complete a 50 MW plant under demanding site conditions.
SCALING ELECTRICAL CONSTRUCTION.
Taking on construction scheduling and client communication as Raggio Solare moved into electrical works at a larger PV construction scale.
LEADING FIRST-TIME PV TEAMS.
Guiding two subcontractors through their first photovoltaic construction on a hybrid solar, wind and Power-to-X development.
WHEN THE SITE CHANGES THE DESIGN.
Supporting an alternative cable-routing solution where conventional trenching wasn't feasible on a 100 MWp site.
17 PROJECTS. ONE PROGRAMME. DELIVERED ON SCHEDULE.
Planning and managing construction schedules across a 17-project PV portfolio, including Megalo Monastiri A & B — delivered on schedule.
BUILDING THE SYSTEM BEHIND THE CONSTRUCTION.
Contributing to the QA/QC plan and reporting framework behind a 40 MWp construction programme.

Field execution and crew coordination at the point of installation.
Every project starts with the ground.
Accuracy becomes infrastructure.
Thousands of connections. One integrated system.
From construction to operation.
04.2 / THE METHOD — SIX DISCIPLINES
Twenty-two systems under the six disciplines of the method, and the build stages each discipline acts in. Every discipline is evidenced only by a role actually held on a real project — the evidence is shown as it is, unequal where it is unequal.
Piling, structures and module installation — the physical plant put in the ground and on the tables.
SYSTEMSPILING · STRUCTURES · MODULES
From DC cabling to LV, MV/HV, earthing, inverters, substations and the grid connection — installed and inspected on real ground.
SYSTEMSDC CABLING · LV SYSTEMS · MV / HV INFRASTRUCTURE · GRID CONNECTION · EARTHING · INVERTERS · SUBSTATIONS
Quality plans, checks, records and technical reporting that let construction be approved rather than argued about.

05 / ENGINEERING TOOLS
Practical calculation tools for photovoltaic construction,
electrical engineering and project planning.
Each instrument below solves a problem that actually stops work on site — a string that will not start on a cold morning, a cable run that loses too much, a crew count that cannot meet the date.
INSTRUMENTS

PLANNED FOR V2
INSTRUMENT 01
Size a PV string so it stays inside the inverter's electrical limits at real site temperatures.
CALCULATE
Size a PV string so it stays inside the inverter's electrical limits at real site temperatures.
Turn a target DC capacity into construction quantities, crew requirements and working days.
Check a DC cable run for voltage drop and conductor loss before it is installed.

SOLAR KNOWLEDGE HUB ↗07 / THE PERSON BEHIND THE PROJECTS
Every project, tool and system on this page traces back to the same starting point — a technician on site, in 2007.
Theodoros started in the field in 2007 — as an electrician, then foreman — before moving into construction engineering on utility-scale solar projects in Kazakhstan, Puerto Rico, Denmark and Brazil. That experience carried into construction management, site management and technical advisory back in Greece — QA/QC, technical documentation and project delivery across international solar projects. Today, that field experience increasingly connects with digitalisation, project controls and power management — bringing construction knowledge and technology into the same workflow. Seven countries, one continuous discipline: get it right in the field first.
Good project delivery begins with understanding what actually happens in the field.
