Your monitoring app is your solar system's health dashboard. A panel failure caught in week 2 costs nothing to fix under warranty. The same failure caught in month 18 means 16 months of lost production — and thousands in missed SMART program payments.
Without monitoring, you only know your solar is working when the electric bill drops. That is a monthly check, not a real-time one. In Massachusetts, three factors make real-time monitoring especially valuable:
The SMART program pays $0.03/kWh for every kWh your system produces, for 20 years. A system producing 20% below estimate means 20% fewer SMART payments. Catching a failed panel in month 1 vs month 12 is the difference between $600 and $7,200 in lifetime SMART losses.
If you have a battery enrolled in ConnectedSolutions, Eversource ($275/kW) or National Grid ($225/kW) dispatches it during summer peak events. Monitoring lets you confirm your battery's state of charge before events and verify participation after.
Heavy snow, ice dams, and debris accumulation can reduce production temporarily. Monitoring helps you distinguish a normal cloudy week from a panel that has been obscured by a lichen-covered branch that grew in over the summer.
Enphase microinverters convert DC to AC at each panel. Every IQ8 or IQ8HC microinverter communicates independently through the Envoy gateway to Enlighten cloud software.

Email/push notifications when panels go offline or production drops below expected threshold
Enlighten mobile app
iOS and Android. Real-time production, system health, and alerts from anywhere
Lifetime kWh dashboard
Track cumulative production, CO2 offset, and equivalent metrics over system lifetime
Envoy gateway required
Local gateway bridges microinverters to cloud. Requires home Wi-Fi. Wired Ethernet option available.
System Status — all panels "green"
All panels showing active production on a sunny day
Any panel showing red or gray on a clear day
Today's Production vs Average
Within 10–15% of the historical average for this date/weather
More than 20% below average on a clear day
Envoy Status
Green — connected and reporting
Offline — check Wi-Fi, restart Envoy
SolarEdge uses a central string inverter with DC power optimizers on each panel. Optimizers enable panel-level monitoring and shade mitigation without full microinverter cost.
Panel-level monitoring via optimizers
Power optimizers on each panel enable individual panel monitoring even with string inverter

Likely Cause
Bird droppings, shading from a new branch, failed microinverter, or optimizer fault
Action
Inspect panel for debris first. If clear on a sunny day and still low, call your installer.
Likely Cause
Inverter fault, grid outage, utility curtailment, or monitoring gateway offline
Action
Check if the house has power. If yes, check inverter/gateway status. If inverter shows error code, contact installer.
Likely Cause
Soiling (pollen season in MA is significant), persistent cloud cover, or a panel failure masked by others
Action
Check weather history. If sunny days are underperforming, inspect for soiling or contact installer for a production review.
Likely Cause
Monitoring gateway lost Wi-Fi — system is likely still producing, just not reporting
Action
Restart router and gateway. Check for Wi-Fi password changes. If offline > 48 hours, contact installer.
Likely Cause
Expected seasonal pattern (low sun angle) or shading from neighbors' trees or chimneys
Action
Compare to your original design production model. If worse than modeled, discuss shade mitigation with installer.
The SMART program pays $0.03/kWh for all production, for 20 years, tracked by your production meter. Your monitoring app should match your SMART payments.
Eversource pays $275/kW and National Grid pays $225/kWfor summer demand response. Events typically run June–September, 3–5 PM.
Know what to expect each season so you can spot anomalies. These are approximate ranges for a 10 kW system in eastern Massachusetts.
| Season / Month | 10 kW System Output | SMART Earnings | Notes |
|---|---|---|---|
| December–January | 350–500 kWh/mo | $10–$15/mo | Short days, low sun angle, snow cover possible |
| February–March | 500–750 kWh/mo | $15–$22/mo | Pollen season begins; production climbing |
| April–May | 900–1,200 kWh/mo | $27–$36/mo | Peak season begins; monitor for pollen soiling |
| June–August | 1,100–1,400 kWh/mo | $33–$42/mo | Peak production; ConnectedSolutions events active |
| September–October | 800–1,100 kWh/mo | $24–$33/mo | Leaf season; watch for shading from deciduous trees |
| November | 400–600 kWh/mo | $12–$18/mo | Rapid production decline; check for debris |
* SMART earnings at $0.03/kWh flat rate. Actual production varies with roof orientation, shading, panel degradation (0.5%/year typical), and local weather.
Monitoring depends on your inverter brand. Enphase microinverter systems use the Enlighten app (iOS/Android) for panel-level monitoring. SolarEdge string inverter systems use the SolarEdge Monitoring Portal and mobile app, with panel-level data via their power optimizers. Both provide real-time production, historical data, and alert notifications.
We recommend checking once a week during the production season (April–October) and monthly in winter. Automated alerts will notify you of significant drops — set up email or push notifications in your monitoring app so you do not need to check manually every day.
Compare your actual production to your system's estimated production from the original quote (kWh/year). Most monitoring platforms show this comparison. As a rough check: a 10 kW system in Massachusetts should produce 1,000–1,200 kWh per month in summer and 400–700 kWh per month in winter.
First check your monitoring app to confirm which panel is affected and when the drop started. Check for obvious shading (branch, debris). If the panel shows zero output on a sunny day with no obstruction, contact your solar installer — it may be a failed microinverter (Enphase) or a power optimizer issue (SolarEdge).
The SMART program pays $0.03/kWh for all solar production (20-year term). Your system's production meter is the basis for SMART payments from your utility. Monitoring lets you catch production shortfalls early — a system producing 20% below estimate translates directly to 20% lower SMART payments.
ConnectedSolutions (battery demand response) uses a separate utility signal, not your inverter monitoring. However, your monitoring portal helps you track battery state of charge before events and verify that your battery participated in each event. Eversource pays $275/kW and National Grid pays $225/kW for summer demand response.
A gateway offline message means the local monitoring hub (Enphase Envoy or SolarEdge gateway) has lost its internet connection. Your solar system is likely still producing — it just cannot communicate that data to the cloud. Check your home router, the gateway's Wi-Fi connection, and restart both if needed.
Every NuWatt installation includes monitoring setup and a walkthrough of your app — Enphase Enlighten or SolarEdge portal. We set up your alerts before we leave.
