All solar PV systems with a transformer-based inverter will require a GEC from the inverter to the grounding electrode. Table 250.66 in the NEC governs the sizing of the GEC.
Some of the methods for calculating coordination costs are: 1. transaction Cost analysis (TCA): This method is based on the economic theory of transaction costs, which are the costs of making an exchange or a contract between two or more parties.
Coordination costs are the resources spent on aligning the activities of different agents, such as time, money, effort, and communication. These costs can have a significant impact on the performance, efficiency, and quality of the outcomes. Therefore, it is important to have reliable methods for calculating and minimizing coordination costs.
Including decommissioning costs in the upfront price of solar projects increases overall project costs, which could discourage solar development. As a result, solar developers are sometimes hesitant to provide or require financial surety for decommissioning costs.
Most homeowners view the installation of a solar PV system as a financial investment. Over time, the power it produces generates savings on their electric bills. Although the costs of residential solar PV systems have fallen significantly in recent years, they still typically cost tens of thousands of dollars.
