Smaller systems may see a more pronounced reduction in financial benefits compared to larger systems that produce a significant portion of a household’s annual energy needs. Similarly, households with higher energy consumption will generally benefit more from net metering than those with lower consumption, even under the revised rules.

Financial Impact Based on System Size and Energy Consumption

The reduced compensation rate for excess energy will translate to lower monthly bill credits for residential solar customers. For example, a household with a 5 kW solar system under the old net metering rules might have seen a significant reduction in their monthly electricity bill, potentially even receiving credits exceeding their energy consumption. Under the new rules, the credit for excess energy will be reduced, resulting in smaller monthly bill credits and a slower return on investment for the solar system.

A larger 10 kW system, however, while also experiencing a reduction in credit, might still offset a greater portion of the household’s energy costs, resulting in a more substantial overall saving, albeit smaller than under the previous net metering scheme. A household with low energy consumption, regardless of system size, will see a smaller reduction in savings compared to a high-consumption household.Let’s consider a hypothetical scenario: A homeowner installs a 7 kW solar system.

Under the old net metering system, this system might have generated 8,000 kWh annually, with 3,000 kWh exported to the grid. Assuming a retail rate of $0.15/kWh, this would result in a $450 annual credit. Under the new system, let’s assume a reduced compensation rate of $0.08/kWh for exported energy. This would reduce the annual credit to $240, representing a $210 decrease in annual savings.

This is a significant difference that will influence the overall financial attractiveness of solar panel installation for many residential customers.
