Common Causes of High True-Up Bills in Solar Systems
True-up bills are annual adjustments that reconcile the energy produced by a solar system with the energy consumed from the grid. Variations can occur due to meter inaccuracies, changes in energy usage, or billing cycle discrepancies. Previous reports on r/solar indicate that some users experience unexpectedly high true-up bills due to meter errors, system miscalculations, or billing cycle misalignments. Typically, utilities perform annual true-ups to account for net metering credits and excess generation, but inconsistencies can lead to surprises for consumers. The specific cause in this case remains unconfirmed, but community discussions often point to common issues like inaccurate readings or system performance changes.
