The following is the situation I have:
- Two buildings on adjacent but separate lots (same owner for both lots but different TMKs).
- Each building has its own service with associated Utility meter and the electrical distribution systems are independent.
- Contractor is proposing to install photovoltaic systems consisting of panels with micro-inverters on both roofs (approximately 150 panels).
- One of the buildings is a warehouse so part of the photovoltaic system on this roof (approximately 80% of the output) will be fed into the electrical system of the adjacent building since it has a greater electrical load.
- We've spoken to the local Utility Company and they have indicated that they typically do not allow photovoltaic systems to span different lots but they seem to be willing to accept this installation if it meets code.
- The Contractor has discussed the matter with the local Building Department and they do not seem to have any objections with the arrangement.
- Are there any "show stopper" issues with the above arrangement?
- Are there any special grounding considerations that would need to addressed in the above situation? In particular, we are concerned about the grounding issues with the photovoltaic system on the warehouse roof being tied into the adjacent building.
- Other than grounding issues are there any other code issues that would need to be addressed?
- Anyone with a similar situation that could share their experience on the matter in regards to the Utility Company or Building Department?
