Start the diagnostic →1. The system is down or underproducing and nobody noticed
Inverter offline, a string out, monitoring stopped reporting months ago. Most homeowners don't find out until the bill arrives.
2. The electric plan pays little or nothing for exported solar
Not every Texas retail plan is solar-friendly. Some pay pennies for what your panels send back, or nothing at all.
3. Household usage grew
New pool pump, EV charger, additional AC unit, a new room. The panels didn't shrink — the load grew.
4. The system was undersized from day one
Built to offset a portion of the bill, not all of it. Sometimes the math on the original quote was optimistic.
5. Lease or loan payment plus the remaining bill is more than the old bill
The panels are 'free' but the monthly payment isn't. Add it to whatever the utility still charges and the total can exceed the pre-solar bill.
6. Billing or meter issues
Wrong meter, wrong rate code, billing errors, plan changed at renewal. It happens more than you'd think.
