Path-Q Solar
Should I request revised quotes if the proposed system size exceeds what my grid connection can accept?
Answer
Yes. Request revised designs that fit the verified interconnection capacity or clearly identify the required upgrades, controls, export limits, and associated costs. Do not assume the quoted system can be installed or operate as modeled if the connection cannot accept it.
Key points
- Ask for the source and date of the stated interconnection limit.
- Compare a smaller system, export-limited operation, storage, service upgrades, or other technically feasible alternatives.
- Require the quote to state who handles applications, studies, upgrades, delays, and additional charges.
- Recheck production and financial assumptions for any reduced or controlled-export design.
What it depends on
- Existing service and interconnection capacity
- System size and export behavior
- Utility study and approval requirements
- Cost and timing of electrical or network upgrades
Risks and trade-offs
- A smaller or export-limited system may produce less usable value than originally modeled.
- Service or network upgrades can add cost and delay.
- Storage or controls may address some constraints but add equipment and operating complexity.
- Proceeding without confirmed acceptance can result in redesign or cancellation.
Information you may need
- Written interconnection assessment or utility response
- Existing service and panel information
- Revised designs and export assumptions
- Upgrade scope, cost responsibility, and schedule
