Understanding your solar meter helps you track production, consumption, and net metering credits accurately — essential for verifying your system performs as expected. Bidirectional smart meters display both energy drawn from and sent to the grid, the key numbers for tracking your solar savings.
Types of Solar Meters
| Meter Type | What It Shows |
|---|---|
| Bidirectional/net meter | Both grid consumption and solar export |
| Production meter (inverter-side) | Total solar generation only |
| Smart meter with app | Real-time and historical data via utility/monitoring app |
Reading a Bidirectional Meter
A bidirectional meter tracks energy flowing in both directions — consumption from the grid and export from your solar system — typically displayed as two separate running totals or a net figure depending on your utility’s meter type.
Understanding Your Production Numbers
Your inverter or monitoring app displays real-time and cumulative production in kWh, letting you compare actual output against expected production for your system size and location.
Using Monitoring Apps
Most modern systems include a monitoring app (Enphase Enlighten, SolarEdge, SMA Sunny Portal) that displays production, consumption, and export data more intuitively than reading a physical meter directly.
Comparing Meter Readings to Your Bill
Your utility bill should reflect the net of consumption and export tracked by your meter — comparing your own readings to the bill helps catch billing errors or unexpected production shortfalls early.

Frequently Asked Questions
What is a bidirectional solar meter?
A meter that tracks both energy drawn from and exported to the grid.
How do I check my solar production?
Via your inverter display, monitoring app, or a dedicated production meter.
Why don’t my meter readings match my utility bill?
Billing cycles, meter reading timing, or rate structure differences can cause discrepancies — contact your utility if the gap is significant.
What monitoring apps are most common?
Enphase Enlighten, SolarEdge, and SMA Sunny Portal are among the most widely used.
Can I read my solar meter without an app?
Yes — most meters display running totals directly on the unit.
How often should I check my solar meter?
Monthly is usually sufficient to catch performance issues before they become costly.
What if my meter shows unexpectedly low production?
Check for shading, soiling, or inverter faults, or contact your installer.
