Hardware-vendor monitoring platforms
SolarEdge ONE: industry-leading dashboard with module-level optimiser data. Huawei FusionSolar: strong dashboard with smart alerting. SMA Sunny Portal: established but ageing UI. Fronius Solar.web: solid mid-market option. All produce monthly generation exports adequate for basic operational management. Limitation: monitoring history tied to hardware — inverter replacement at year 12-15 may not migrate cleanly.
Independent third-party monitoring layer
Vendor-agnostic monitoring aggregates data from any inverter brand into a single time-series database. Persists across hardware changes. Provides audit-ready monthly export pre-formatted for SECR submission, CDP Supply Chain disclosure, EcoVadis, and customer-specific verification certificates. Critical for 25-year audit continuity. We deploy this layer alongside hardware-vendor monitoring as standard.
Audit-ready monthly export structure
Standard audit export: total kWh generated; kWh self-consumed; kWh exported under SEG; gross/net Scope 2 reduction calculated using current UK Conversion Factors (location-based + market-based methodologies); equivalent CO2 abatement; year-on-year comparison vs PVSyst forecast; system availability percentage. Format aligned with major customer audit programmes.
Common questions
How much does solar monitoring cost?
Hardware-vendor monitoring is included in inverter cost. Independent third-party monitoring: £1.50-£3 per kW per year subscription. For 1 MW system: £1,500-£3,000/year. Often bundled into O&M contract.
Does SECR require specific monitoring format?
SECR requires Scope 2 emissions disclosure using UK Conversion Factors. Our independent monitoring exports format directly for SECR ingestion. Pre-formatted exports for SECR Reporter, Greenstone, Worldfavor, Watershed, Persefoni platforms.
