Work out net metering credit instantly with clear inputs, formula shown and shareable results.
Self-consumed solar avoids the full import tariff; exported solar earns only the export credit, which is usually far lower. Because generation and consumption rarely coincide perfectly, only around 60-80% of solar output offsets load directly without storage or load shifting.
Net metering
Saving = consumption x import rate - (imported x import rate - exported x export credit)
The value of a self-consumed unit is the import tariff, often two to three times the export credit. Shifting load into daylight hours can be worth more than adding panels.
Net metering offsets exported units against imported units on a volumetric basis. Net billing values exports at a separate, usually lower, rate. The distinction changes project economics substantially.
