For instance, California’s Self-Generation Incentive Program (SGIP) provides rebates for solar installations, while some states offer tax exemptions for solar property improvements. Local municipalities may also offer additional incentives, such as expedited permitting processes or grants. These programs often have application deadlines and specific eligibility criteria. Checking with your local utility company and government agencies is crucial for identifying available programs.

Financial Impact of Net Metering with Different Tariff Structures

The financial impact of net metering varies significantly depending on your utility’s rate structure. Here’s a comparison:

Time-of-Use (TOU) Tariffs: With TOU tariffs, electricity prices vary throughout the day. Net metering is particularly beneficial under TOU rates as you can generate excess energy during peak hours (when rates are high) and use credits during off-peak hours (when rates are low). This can lead to substantial savings. For example, a household using a TOU rate structure might see a 50% reduction in their electricity bill after installing a solar panel system and participating in net metering.
Flat-Rate Tariffs: Under flat-rate tariffs, electricity prices remain constant throughout the day. While net metering still offers savings, the financial benefit is less pronounced compared to TOU tariffs. The savings are primarily derived from reducing your overall energy consumption. For example, a household with a flat-rate tariff might see a 30% reduction in their electricity bill with a similar solar panel system and net metering.
Feed-in Tariffs (FITs): Some jurisdictions offer FITs, where the utility pays a fixed rate for every kilowatt-hour (kWh) of excess energy you feed into the grid. This provides a predictable and potentially lucrative income stream, irrespective of your energy consumption patterns. For example, a FIT program might offer $0.15 per kWh, providing a consistent income based on the amount of excess energy produced.

It’s important to analyze your utility’s rate structure and the specific terms of your net metering agreement to accurately assess the financial impact.
