• Solar monitoring dashboard polling inverters every 15 minutes and missing fault events until the customer calls to report zero generation?

  • Customer-facing portal showing raw kWh numbers with no context about expected output, savings to date, or what a fault alert means?

Solar Monitoring Software Development

Real-time generation data from inverters, meters, and weather sensors. Fault detection with automated alerting. Customer portals that show output, savings, and system health in plain language. Fleet dashboards for installers managing dozens or hundreds of sites.

We build custom solar monitoring platforms for installers, EPCs, and asset owners. From inverter API integration to portfolio-level performance analytics, we cover the full monitoring stack.

  • Real-time generation data from inverters, meters, and weather sensors

  • Fault detection with automated alerting and severity classification

  • Customer portal with generation, savings, and environmental impact

  • Fleet-level monitoring for installers managing multiple sites

Solar monitoring software connects inverter and meter data to a platform that tracks real-time generation, detects faults before customers call, and gives site owners a clear view of output, savings, and system health. RaftLabs builds custom solar monitoring platforms for installers, EPCs, and asset owners -- from single-site customer portals to fleet-level dashboards managing hundreds of systems.

Faults you find first cost less than faults your customers find

A 15-minute polling interval is standard for most inverter APIs. A fault that trips at 9am and stays undetected until the customer calls at 3pm is six hours of lost generation. Multiply that across a fleet of 200 sites and the performance gap adds up fast.

Custom solar monitoring software changes the response model. Real-time event streams from inverter APIs detect faults in minutes, not hours. Automated alerts route to the right technician with fault type, severity, and site detail attached. The customer sees a clear status in their portal before they think to call.

What we build

Real-time data ingestion and processing

Inverter data ingestion via manufacturer APIs and local Modbus or SunSpec connections. Support for SolarEdge, Enphase, Fronius, SMA, Huawei, and ABB inverter platforms. Smart meter integration for import, export, and self-consumption tracking. Weather station and irradiance sensor feeds for performance ratio calculation. Data normalised to a common schema regardless of inverter brand. Polling intervals configured per site based on API limits and monitoring requirements -- event-driven triggers for fault conditions rather than waiting for the next scheduled poll.

System performance and yield analysis

Performance ratio calculation comparing actual generation against expected output from irradiance and system capacity. Yield analysis at system, string, and inverter level to identify underperforming components. Specific yield tracking against design estimates and comparable nearby systems. Clipping detection for systems where inverter capacity is undersized relative to array output. Daily, monthly, and annual generation summaries with trend views. The analysis layer that tells you whether a system is performing to spec -- not just that it is generating something.

Fault detection and alerting

Fault event processing from inverter alarm registers with classification by fault type and severity. Rule-based and anomaly detection for fault conditions that do not trigger inverter alarms -- string-level underperformance, intermittent communication loss, and production shortfall relative to irradiance. Alert routing by severity: critical faults to the on-call technician by SMS, degradation alerts to the service queue by email. Alert suppression rules for known conditions like grid curtailment or scheduled maintenance windows. The detection that finds faults before lost generation compounds into a warranty or insurance claim.

Customer-facing solar portal

Customer portal showing daily, monthly, and lifetime generation in plain language -- kilowatt-hours produced, estimated bill savings, and equivalent carbon offset. Expected output comparison so the customer can see whether the system is performing normally without needing to understand performance ratio. Fault status with plain-language explanations of what the alert means and what happens next. Mobile-responsive design that works on the phone the customer will use to check it. Branded to the installer, not the monitoring platform vendor.

Fleet and portfolio monitoring

Fleet dashboard for installers and asset managers showing all sites in a single view. Site-level status indicators: generating normally, degraded, faulted, or offline. Portfolio-level generation summary and performance metrics for the current day, month, and year. Filter and sort by status, system size, installer, or geographic region. Bulk alert review so a technician can triage a full site list without opening each system individually. The operational view that makes managing 50 or 500 sites as manageable as managing five.

Historical data and reporting

Long-term data retention with efficient time-series storage for multi-year generation history. Automated monthly performance reports delivered to customers by email. Annual generation summaries for feed-in tariff reconciliation and warranty documentation. Custom report builder for asset owners who need generation data in specific formats for investors or offtake counterparties. Data export in CSV and JSON for integration with asset management or accounting systems. The records layer that makes generation history useful beyond the monitoring dashboard.

Frequently asked questions

We integrate with the major residential and commercial inverter platforms: SolarEdge via the Monitoring API, Enphase via the Enlighten API, Fronius via the Solar.web API and local Fronius Data Manager, SMA via the Sunny Portal API and local SMA Modbus interface, Huawei via the FusionSolar API, and ABB via FIMER. For inverters without a published API, we use local Modbus TCP or SunSpec protocol over the site network. Where a site has mixed inverter brands -- common in commercial retrofits and aggregated portfolios -- we normalise data from each brand to a single schema so fleet reporting is consistent. We review your inverter mix during scoping and confirm integration feasibility before development starts.

Threshold alerting fires when a value crosses a fixed line -- generation below zero, inverter offline, communication lost. It catches hard failures but misses the degradation that costs money before it becomes a hard failure. Fault detection goes further. It compares actual output against expected output given current irradiance, flags string-level underperformance that the inverter does not classify as a fault, and detects intermittent failures that clear before the next poll. It also suppresses false alerts during grid curtailment, low-irradiance mornings, and scheduled maintenance windows -- so technicians spend time on real faults, not investigating alerts that resolve themselves. The result is fewer missed faults and fewer unnecessary truck rolls.

Most solar customers do not know what a performance ratio is. They want to know three things: is my system working, how much did it save me this month, and what do I do if something is wrong. We design the customer portal around those questions. Generation is shown in dollars saved and carbon offset alongside kilowatt-hours. System status is shown as a clear indicator with a plain-language explanation -- not an inverter fault code. Alerts include a description of what the alert means and what the next step is, so the customer knows whether to call a technician or wait for the installer to follow up. We test the portal design with real users during development to check that the information is clear to someone who installed solar two years ago and has not thought about it since.

A customer-facing monitoring portal for a residential or small commercial installer -- inverter API integration for one or two brands, generation and savings dashboard, fault alerting, and customer portal -- typically costs $30,000 to $80,000 depending on the number of inverter integrations and the complexity of the customer portal. A full fleet monitoring system for an EPC or asset manager -- multi-brand inverter integration, performance analytics, fleet dashboard, automated reporting, and historical data storage for a large portfolio -- runs $60,000 to $150,000. We scope the project before pricing it so you know the cost and delivery timeline before development starts.
