A site’s solar feasibility is largely determined by return on investment, which depends on state net metering policies and utility interconnection tariffs. When full net metering isn’t available, or system sizes exceed tariff limits, ROI becomes harder to predict and requires estimating how much energy will be used on-site versus exported to the grid. To better understand this, the paleBLUEdot team researched typical on-site solar consumption by building type. This post shares our findings.
