Xcel’s Time-of-Use on-peak window runs 5–9 p.m. on non-holiday weekdays. In winter, that’s when it’s dark, the heat is running and dinner is on. A home battery can carry you through those hours on your own stored solar.
On Time-of-Use, the same kilowatt-hour costs more during on-peak hours than off-peak. Most Xcel homes in Colorado are now on Time-of-Use by default, so the evening rush in your house lines up with the priciest hours on your bill.
Panels make the most power around midday. On short winter days the sun is down before the on-peak window ends, so without storage your evening power comes from the grid at the peak price.
A battery charges from your panels during the day and runs your home during on-peak hours. How much that helps depends on your usage, your roof and your rate plan, so we start with your actual Xcel bill.
Your Xcel bill and rate, your evening loads (heat, cooking, EV charging) and whether you already have solar. Then you get a straight answer.
