Xcel Energy solar: what Colorado homeowners should verify

## Confirm the account and rate Check the exact rate schedule on your Xcel bill (residential, TOU, EV, etc.). System sizing and payback assumptions depend on it. Do not accept a proposal that assumes a rate you are not on. ## Interconnection application, not marketing Ask your installer to show you the actual Xcel interconnection application timeline they are seeing this month — not a marketing number. Timelines change and vary by service territory. ## Net-metering credit rules Ask how excess solar credits are handled monthly and at annual true-up, in writing, referencing Xcel's published tariff. Do not rely on verbal assurances. ## System-size cap Colorado's residential net-metering cap is tied to your recent usage. Confirm the exact sizing rule Xcel is applying to your account, especially if you plan to add an EV, heat pump, or addition later. ## What to save Save the interconnection agreement, the permission-to-operate notice, and the first three post-installation bills. If anything looks off, those are the documents you will need.
