Solutions & Services
From permitting to operation: integrated solar across the full lifecycle
ELECRO manages the full life cycle of a photovoltaic generation asset: engineering and EPC/EPCM execution, permitting, bankable financing structuring and an equipment supply chain from verified sources. Our services cover two distinct client segments: industrial investors — utility-scale, rooftop C&I, floating PV — and residential and prosumer clients.
EPC · EPCM
Engineering, procurement and execution
Floating PV
Floating systems on water bodies
O&M · BESS
Operation, maintenance and storage
EBRD · IFC · EIB
Institutional financing structuring
Pillar A
Engineering & EPC/EPCM Execution
Full-cycle general contracting: technical design, equipment procurement, on-site construction, commissioning and operation. We cover greenfield and brownfield, on-grid and prosumer.
Rooftop C&I Systems
Rooftop installations for Commercial & Industrial clients: self-consumption, lower energy bills and reduced spot-price exposure, prosumer status or corporate PPA schemes.
Floating PV Systems
Floating photovoltaic systems on lakes, reservoirs and industrial water bodies — lower module operating temperature and thermal losses, with no use of agricultural land. A segment with low penetration on the local market.
Residential & Prosumer PV
Turnkey systems for homes and small businesses (B2C): consumption-based sizing, installation, prosumer grid connection and support for financing through the Casa Verde Fotovoltaice scheme.
O&M — Operation & Maintenance
Long-term operation and maintenance: preventive and corrective maintenance, production monitoring, warranty management and performance reporting — protecting the asset yield and bankability.
BESS Storage
Battery Energy Storage Systems, co-located with PV parks for firm output, system services and improved bankability. Eligible under the Modernisation Fund.
How we work
The EPC process, step by step
A single accountable counterpart from the first site assessment to long-term operation — the EPCM model that reduces interfaces and risk for the investor.
1. Site assessment & feasibility
Land or rooftop analysis, solar resource evaluation, grid connection options and techno-economic feasibility; production estimates and bankability indicators.
2. Design & permitting
Detailed technical design and navigation of the permitting chain: ATR/CR grid connection, environmental approvals (including Natura 2000), urban planning (CU/AC) and fire safety (ISU).
3. Procurement
Equipment procurement (modules, inverters, structures, substation, BESS) with supply-chain securing, quality control and negotiation of product and performance warranties.
4. On-site construction
Construction proper: civil works, mounting structures and modules, electrical works, transformer station and grid connection — with project management, HSE and schedule control.
5. Commissioning
Testing, commissioning, energisation and obtaining operating documents; handover to the beneficiary with a complete technical file and verified performance parameters.
6. Operation & Maintenance
Transition to O&M: continuous monitoring, scheduled maintenance and corrective interventions, with periodic reporting to sustain yield over the asset lifetime.
EPCM model with a single contract owner
Full traceability of equipment and warranties
HSE coordination and schedule management on site
Pillar B
Consulting, Permitting & Financing
The most costly risk of a solar project is not construction, but permitting and bankability. ELECRO drives the project through the full procedural chain and structures it to be financeable.
From 2026, projects above 5 MW connect through grid-capacity allocation auctions run by Transelectrica, and only a fraction of permitted MW actually reach operation. We position ourselves on completion and bankability, not merely on obtaining approvals.
- ATR / CR — technical grid approval and connection certificate (DSO / Transelectrica)
- ANRE — generation and supply licences
- Environmental approvals — environmental permit, EIA, Natura 2000 / biodiversity
- Urban planning — Urbanism Certificate (CU) and Building Permit (AC)
- ISU — fire safety approval and authorisation
Permitting & Approvals
We manage the entire authorisation file — grid connection (ATR/CR with the distribution operator, or Transelectrica for large projects), ANRE licensing, environmental approvals (including Natura 2000, also relevant to taxonomy DNSH), urban planning (CU/AC) and fire safety (ISU). On-shore and floating solutions.
Financing & Bankability Structuring
We structure financing through international financial institutions (EBRD / IFC / EIB) and commercial banks and prepare the asset for Contract for Difference (CfD) schemes. For national schemes we guide towards the Modernisation Fund (PV >1 MW + storage), NRRP/REPowerEU, Casa Verde Fotovoltaice (prosumers) and Electric Up (SMEs/HoReCa).
Pillar C
Supply Chain
The supply component that backs EPC execution and serves third-party developers — with a focus on availability, certified quality and predictable delivery.
Equipment & Component Supply
Supply of photovoltaic modules, inverters, mounting structures, storage systems and balance-of-system equipment, both for our own projects and for third-party developers and installers.
Supply-Chain Securing
Reducing supply risk through source diversification, compliance and traceability checks, quality control on receipt and logistics planning aligned to the construction schedule.
Brands & equipment represented
We work directly with top-tier, bankable (Tier-1) equipment manufacturers: PV modules, inverters and storage systems selected for reliability, solid warranties and long-term spare-parts availability.

Pillar D
Maintenance, Cleaning & Operation (O&M)
Production is sustained through disciplined operation, not installation. An unmaintained photovoltaic system loses between 5% and 20% of its annual yield through soiling build-up, silent electrical degradation and undetected faults. ELECRO covers the full O&M cycle for industrial systems (C&I, rooftop, utility-scale) and residential ones, with top-tier equipment adapted to each installation type, an ANRE-certified team and protocols aligned to IEC 62446-1/3, IEC 62548 and EN 50618 — to protect the asset yield, its bankability and the validity of manufacturer warranties.
24/7 SCADA Monitoring
We integrate the manufacturer native platform with ELECRO O&M Hub — a unified dashboard per string, MPPT and inverter, available on web and mobile with multi-factor authentication. Dual alarm thresholds (investigation at deviations above 5%, urgent intervention above 10%), no significant fault undetected for more than 60 minutes and SMS/email alerts to operator and owner in under 15 minutes, with a T+0 alarm → T+1h confirmation → T+4h preliminary report → T+24h on-site for critical faults (P1/P2) → T+72h on-site for non-critical faults (P3/P4) escalation protocol.
Drone Thermographic Inspection
High-resolution thermal-sensor drone for automatic detection of hot-spots at cell, module and string level, under irradiance of at least 600 W/m². Anomalies (hot-spots, faulty bypass diodes, microcracks, delamination, string mismatch, oxidised connections, inactive strings) are classified per IEC TR 56257 thresholds, while ground-level inspection with a handheld thermal camera completes the flight for inverters, panels and cable runs. Data is correlated with SCADA monitoring. Flights per EU 2019/947 and AACR, certified A2/A3 pilot.
Professional Cleaning & Hygiene
Pure demineralised water (reverse osmosis) produced on site, with no abrasive agents or unauthorised detergents. For industrial systems (above 50 kWp) we use a dual-brush cleaning robot (capacity of roughly 2 MW/day) plus a telescopic-arm system for inaccessible areas; for residential (below 50 kWp), professional manual equipment. Soiling losses, of 5–15% depending on the season, are recovered through periodic campaigns.
Preventive & Corrective Maintenance
Campaign-based protocol — industrial standard of 4 campaigns per year, across 5 categories: mechanical (module, frame and structure integrity), electrical (voltages and currents, insulation, earthing, connectors), active equipment (inverters, firmware, cooling, panels), SCADA (connectivity, weather-sensor calibration) and auxiliary structures. Residential 1–2 campaigns per year. We manage in-warranty replacements directly with the manufacturers.
Electrical Inspection & Testing
Per IEC 62446-1: Voc/Isc testing per string and MPPT with temperature correction, DC cabling insulation-resistance measurements, earthing continuity, verification of DC/AC protections (SPD, fuses, breakers, RCD) and MC4 connectors, all assessed against the standard thresholds. The IEC 62446-1 compliance report is required for warranty retention, reporting to financiers (EBRD, IFC, banks) and third-party technical audit.
Reporting & Performance KPIs
KPIs per IEC 61724-1: target Performance Ratio of at least 78% for industrial and 75% for residential, benchmark Specific Yield for Romania of 1,200–1,500 kWh/kWp/year, availability of at least 97%, critical-alarm response time under 24h, P1–P4 incident classification and loss attribution (soiling, faults, shading, degradation). Monthly, post-intervention (within 14 days), annual and ad-hoc reports, delivered as PDF with CSV/Excel export.
How we work
The maintenance campaign, step by step
1. Visual pre-inspection
Visual inspection of the PV field and equipment — modules, structures, cabling, inverters — with photo documentation used as a comparison baseline for later campaigns, and identification of obvious defects and risk areas before intervention.
2. Cleaning & hygiene
Cleaning with pure demineralised water and equipment adapted to the system (dual-brush robot for industrial, professional manual equipment for residential), with no abrasive agents and controlled water-consumption management.
3. Electrical checks
IEC 62446-1 protocol: string and MPPT testing, insulation and earthing-continuity measurements, DC/AC protection and connector verification, connection re-torquing and control of operating parameters.
4. Thermographic inspection
Drone scan under irradiance of at least 600 W/m², with anomalies classified per IEC TR 56257 thresholds and ground-level completion for inverters and panels; results are correlated with the electrical measurements from step 3 for precise fault localisation.
5. Report & recommendations
Report delivered within 14 days: findings, measurements, thermograms, classified defects, a prioritised remediation plan, performance KPIs and recommendations, with estimated production gain. PDF format with CSV/Excel export.
