A lot of people picture solar making the JPS bill disappear entirely. Most of the time it shrinks the bill, sometimes to a fraction of what it was, but a bill still lands each month. That is not a catch, once you understand how it works. Here is the honest version.
Why a bill still comes
As long as your home is connected to JPS, and almost every solar home is, you are still using the grid. You draw from it at night and during cloudy spells when your panels are not covering you, and you send surplus back to it during the day. JPS still meters all of that and still bills you for it. The only way to stop getting a JPS bill is to cut the connection entirely and go fully off-grid, which we will come back to. You can see how the bill is laid out on the JPS understanding your bill page.
The fixed charge solar cannot erase
Here is the part that surprises people. Every JPS bill carries a fixed customer or service charge just for being connected, separate from the electricity you actually use. Your solar production and your export credits chip away at the energy part of the bill, but they do not wipe out that fixed charge. So even in a brilliant solar month where you barely touched the grid, a small bill still turns up to cover the connection itself.
How the bill is built
Roughly, your bill is what you drew from the grid at the retail rate, minus credit for what you exported at the lower avoided-cost rate, plus the fixed charges and taxes. Solar shrinks that first part, the energy you buy, and that is where the big savings come from. We go through the credit side in how JPS net billing actually works. The fixed part stays put regardless of how much you generate.
Can the bill ever reach zero?
In practice, only by going fully off-grid, with no JPS connection at all. That ends the JPS bill, but it also means no grid to fall back on, so you need a larger system and battery to carry you through every cloudy stretch on your own. Most people keep the JPS connection precisely because the grid is a handy backstop, and they accept a small standing charge as the price of that safety net. A big drop in the bill, yes; a zero bill while still connected, no.
The honest takeaway
Solar is about a much smaller JPS bill, not usually no bill at all. Sized well to your usage, it can cut the energy part of the bill dramatically, and that is where the value is. The fixed connection charge remains while you stay tied to the grid, which for most homes is a fair trade for keeping the grid as backup.

Do you still get a JPS bill if you have solar?
Yes, in almost all cases. As long as your home stays connected to JPS, you still use the grid at night and on cloudy days and export surplus during the day, and JPS bills you for that. Solar usually shrinks the bill a lot, but a bill still comes each month while you are grid-connected.
Why is there still a charge even if I barely use the grid?
Because every JPS bill includes a fixed customer or service charge just for being connected, separate from the energy you use. Your solar and export credits reduce the energy part, but they do not erase that fixed charge. So even a great solar month leaves a small bill covering the connection itself.
How is my bill calculated with solar?
Roughly, it is what you drew from the grid at the retail rate, minus credit for what you exported at the lower avoided-cost rate, plus fixed charges and taxes. Solar shrinks the energy you buy, which is where the savings come from, while the fixed connection charge stays the same regardless of how much you generate.
Can my JPS bill ever be zero?
Practically, only if you go fully off-grid with no JPS connection at all. That ends the bill but removes the grid as a backup, so you need a larger system and battery to cover every cloudy spell yourself. While you stay connected, the fixed charge means the bill drops a lot but does not reach zero.
Should I disconnect from JPS to avoid the bill?
Usually not. The grid is a useful backstop, covering you when your panels and battery run short, and staying connected lets you draw and export power. Most homes keep the connection and accept the small fixed charge rather than build the much larger off-grid system needed to never touch the grid.
How much will solar cut my bill?
It depends on your usage and how the system is sized, but the energy part of the bill, the largest part for most homes, can drop dramatically. The fixed charge remains. The way to cut the bill as far as it sensibly goes is to size the system to your real usage, which is what a proper assessment works out.
