Understanding the ins and outs of solar interconnection methods can be a bit perplexing given the various service equipment setups and local regulations. When hooking up your solar PV system to the existing electrical system, it's crucial to tread carefully.
Determine Method of Interconnection: There are two different ways to connect solar panels to an industrial building, line-side tap connection and load-side tap connection. A line-side tap connection consists of connecting solar panels on the utility side of a building's primary electrical panel/switchboard.
The utility company must authorize this connection to receive approval to interconnect. In addition, the solar panels and equipment must meet specific qualifications to ensure the proper voltage, power quality, and reliability. Therefore, interconnection management can be relatively complex, especially for larger projects.
Utility-scale projects either connect directly to a substation or a transmission line of 69 kV or higher. Unless a solar farm is installed next to transmission lines or substations, the solar contractor needs to install a generation tie to connect the clean energy project to the grid.
It is typically not cost-effective to connect a small solar project to a high-voltage transmission line because the cost of interconnection typically increases by the voltage of the power line. Larger commercial projects, such as a community solar farm, usually need to be connected to a three-phase distribution line.
However, utility interconnection might not be much more complicated for small commercial projects than residential solar installations. Not correctly identifying all the costs related to interconnection can result in numerous change orders and can increase the total cost of the solar system. This can lead to dissatisfied customers and delays.
