What are “Solar Arrays”?

The term "solar array" is often used to describe large-scale solar power projects; however, it can also refer to groupings of solar panels. As the most important part of a solar panel system, solar arrays hold the panels, collect sunlight, and convert it into electricity. Save energy and lower your business’ electric bill by investing in a renewable solar energy project.

Why is an application needed for interconnection if power won’t push back to the grid?


For the safety and reliability of the grid, it is imperative that parallel connected generators participate in our interconnection process, whether they intend to net export power or not.

First, distributed energy resources increase fault current on the Duquesne Light power grid. If Duquesne Light is not aware of these DER installations, equipment, such as circuit breakers or other protective devices, may be rated incorrectly for a lower fault current, ultimately causing issues with safety and reliability.

Additionally, if a customer installs generation without notifying the utility and going through the correct process, that generation could mask customer load, and as such give the utility an incorrectly low perception of customer load. This could impact service reliability during periods when the generation is not operating.

Terms and Requirements

*Only energy usage that is offset at the facility is eligible for a rebate. No rebates are available for excess energy.
