What we do

Technical integration, from commissioning to curtailment

With 25+ years of combined field experience and over 500 MWp commissioned, we're the independent team that asset owners, O&M contractors and EPCs call when systems need to work — not just look good on paper.

📡

SCADA, Monitoring, Curtailment & Comms

We design the monitoring and curtailment system from day one — selecting hardware, defining signals, architecting the communication chain. Everything verified before the first kWh is produced.

Commissioning & Integration

Independent commissioning for PV, BESS and hybrid sites. We stage, configure and verify everything before the system goes live — not after.

Operations & Maintenance

Full technical O&M for solar portfolios — scheduled maintenance, performance monitoring, fault resolution and transparent reporting. Also available as standalone inspections or interventions.

Repowering & Curtailment

Legacy commercial rooftop or utility-scale — when inverters reach end-of-life or curtailment becomes mandatory, we design the upgrade and commission the result.

How we work

Independent. Field-first. End-to-end.

01

Independent

We work with every major platform on the market. Our recommendations are based purely on what fits your site technically — that independence is what our clients value most.

02

Hands-on

Our team is at home on site. We troubleshoot hands-on, with real tools and real measurements. When something needs fixing, we're there.

03

End-to-end

From physical installation to SCADA data verification to grid compliance. One team, one point of contact, the full chain covered.

Commissioning & Integration

Where promises meet reality

We don't wait until hardware is on site to start commissioning. Monitoring systems are designed, controllers are staged and configurations are tested before anything ships. By the time equipment arrives, the integration plan is proven — not improvised.

Network configuration, sensor connections and platform setup are all prepared and tested before equipment leaves for site. Once installed, we power up, verify the network, and connect to local hardware — inverters, power analysers, meters. The result: a smooth handover with minimal time on site and no surprises at go-live.

  • Pre-staging and configuration before hardware reaches site
  • Verified SCADA and monitoring data flow end-to-end
  • Independent commissioning report with punch list
  • Single point of contact for multi-vendor sites

Operations & Maintenance

Your assets. Our responsibility.

O&M shouldn't be a box-ticking exercise. We provide hands-on technical operations and maintenance for solar portfolios — combining deep field experience with independent monitoring and reporting. Every site gets a clear maintenance schedule, verified performance data, and fast response times when something goes wrong.

Whether you're an asset owner looking for a reliable technical partner, or an investor who needs transparent reporting and SLA-backed response times — we treat your portfolio as if it were our own.

Not looking for a full O&M contract? We also offer standalone inspections, due diligence assessments, drone surveys and rapid interventions.

  • Preventive and corrective maintenance
  • Performance monitoring and yield verification
  • Structured reporting for asset owners and investors
  • Acquisition due diligence with independent reporting
  • Thermal and visual drone inspections
  • Technical evidence for insurance damage claims
  • Scalable from single sites to multi-asset portfolios

Repowering & Curtailment

Upgrade ageing assets. Meet grid requirements.

Belgium and the Netherlands have thousands of commercial rooftop PV systems from the early subsidy era — ageing inverters, low efficiency, no or defective monitoring, and no curtailment capabilities. These legacy parks face a choice: keep patching, or repower and unlock years of additional production while meeting grid requirements and unlocking new revenue streams.

  • Independent inverter upgrade design and commissioning
  • Post-damage system redesign after storm or fire
  • Curtailment implementation — RTU, telecontrol, end-to-end testing
  • Making legacy parks grid-compliant and monitorable again

Designed right from day one — not patched after the fact

Most monitoring problems start before a site is even built. The wrong sensor selected. A signal missing from the transformer. A metering point overlooked in the curtailment chain. By the time someone notices, production data is incomplete and revenue is leaking.

We get involved early — during the design phase. We define which signals need to be captured, select the right hardware for each measurement point, and architect the full communication chain. By the time the first kWh is produced, everything is monitored, controlled and verified.

  • Monitoring system design from pre-commissioning stage
  • Sensor and hardware selection for transformers, meters, weather stations
  • Independent: compatible with all major inverter and monitoring platforms
  • Cellular routers with failover and VPN
  • Modbus TCP/RTU networking, fibre backbone, SIM management
  • RTU installation for grid operator telecontrol
OT Security

Security built into every deployment

NIS2 obligations are reaching solar and storage operators across Europe. We build OT security into how we design networks and configure systems — network segmentation, secure remote access, firmware management and access control. Not as an afterthought, but as standard practice.

Need a cybersecurity readiness assessment for your portfolio? We can help you understand where you stand.
