Independent solar PV engineering support
Find what is holding your solar asset back.
FiMetric helps PV owners, EPCs and O&M teams make better technical decisions—from design review and commissioning to fault diagnosis, performance recovery and practical O&M engineering.
Remote internationally. Field-ready in Armenia.Independent technical support backed by real operational experience across residential, commercial and industrial PV systems.
What we do
Engineering support for the full life of a PV system.
We work alongside your internal team or local field crew: identifying the real technical issue, assessing the evidence, and turning findings into clear next steps.
Our work is independent of equipment sales. That means recommendations are driven by system performance, reliability and field practicality—not a product quota.
Commissioning support
Handover checklists, monitoring setup, acceptance testing, documentation review and practical support for new-site delivery.
Fault diagnosis
Structured remote investigation of inverter, monitoring, grid, communication and equipment faults—with a clear escalation path for site teams.
Performance analysis
Compare actual and expected generation, isolate losses, validate equipment behaviour and quantify recoverable energy.
O&M engineering
Monitoring strategy, issue prioritisation, maintenance planning, SOPs and practical operating workflows for PV assets.
Technical documentation
Clear reports, technical findings and action plans that help owners, suppliers, contractors and grid operators make decisions faster.
A better way to investigate
Evidence first. Fixes second.
PV problems are expensive when they are guessed at. Our approach is built around restoring visibility, testing the actual failure mechanism and documenting the path to recovery.
01
Restore visibility
Recover monitoring and establish what the data can—and cannot—prove.
02
Test the hypothesis
Compare expected versus actual behaviour and confirm the root cause with targeted checks.
03
Prioritise action
Translate findings into the most valuable, safe and practical corrective actions.
04
Verify recovery
Use monitoring and measured performance to validate that the solution has worked.
Selected case studies
Different systems. Measurable recoveries.
These projects demonstrate the type of engineering investigation FiMetric performs. Three sites are anonymised to protect client confidentiality.
Anonymised / Armenia / 3 MW industrial
Restoring a neglected microinverter plant
A long-unserviced industrial PV plant had incomplete monitoring, equipment failures and overheating cable issues. After reconnecting monitoring, the team isolated faults, replaced defective equipment, corrected cable sizing and secured warranty replacements for most failed microinverters.
RECOVERED ANNUAL ENERGY1,040,000 kWh recovered; production improved from 68% to 94.5%, accounting for panel degradation.
Masis Fishery / Armenia / 500 kW
Proving a hidden module-performance issue
With normal azimuth, tilt and inverter operation, the site still produced more than 26% below expectation. Comparative controlled testing against known-performing modules established that the installed panels did not meet their stated parameters. The manufacturer supplied compensating modules.
RECOVERED ANNUAL ENERGY175,500 kWh recovered through validated testing and a manufacturer remedy.
Anonymised / Armenia / 10 kW residential
Resolving repeated daytime grid trips
A Solax inverter repeatedly disconnected as grid voltage rose during peak production. Site testing showed several PV systems shared an undersized, high-impedance feeder; export current caused voltage rise at the connection point until the inverter reached its protection threshold. The grid operator replaced the cable.
RECOVERED ANNUAL ENERGYApproximately 15,000 kWh of annual production restored.
Anonymised / Armenia / 500 kW commercial
Protecting a PV site without sacrificing output
A commercial Hoymiles microinverter station adjacent to a golf course suffered recurring module damage from high-velocity golf balls. FiMetric replaced damaged equipment and designed the placement of a protective safety net to limit shading while eliminating the ongoing failures.
OUTCOMEZero further panel breaks; approximately 5,000 kWh/year shading loss versus roughly ten times higher annual replacement cost.
Anonymised / Armenia / 172 kW commercial
Restoring a vandalised PV asset after theft
An unsecured field-based PV plant near a gas station was robbed: around half of its Hoymiles microinverters and DC cabling were removed. The DC cables had been cut so close to the junction boxes that standard replacement work could not reconnect the affected modules.
OUTCOMEFiMetric restored the plant by opening junction boxes and installing new 1 m DC cable extensions, while monitoring data helped establish when the first and last inverters went offline. The site returned to operation with a new fence and security cameras.
