This report compares 134 complete overlapping days of revenue-grade CMP hourly meter data and SolarEdge 15-minute monitoring since solar commissioning (2026-02-16), rolled up into 4 monthly billing windows (2026-03 through 2026-06).
On grid import, the two meters show excellent agreement: SolarEdge reads 0.14 kWh/day lower than the CMP meter on average (MAPE 1.8%, r = 0.996). On grid export they show excellent agreement: bias +0.01 kWh/day, MAPE 2.5%, r = 0.999. Since the CMP meter is the revenue meter, SolarEdge CT-clamp readings are informative but any disagreement here does not affect billing.
Billed usage reconciles with the revenue meter: across the 3 fully-covered windows CMP billed 1 kWh (0.0%) more than the meter recorded — within normal read-timing tolerance.
On the production side you are receiving full value: CMP credited 2886 kWh against 2886 kWh of metered export — 0 kWh more than the meter total, worth about $760.97 at the retail rate of $0.2637/kWh.
Excluded from the verdict for incomplete revenue-meter coverage: 2026-03 (meter 22/29 days). Gaps in the hourly archive make bill comparison unreliable for those windows.
Verdict: net metering is paying you properly. Bills match the revenue meter on both usage and generation credit, and the 2886 kWh credited so far returned about $760.97 of retail value.
