Community Solar Bill Credit Optimizer
Stack your community solar subscription cost against the bill credits it generates. Provide the kWh allocated to your account and the subscription rate to see how much cash you save versus paying full retail rates, along with the effective discount those credits deliver.
Confirm credit multipliers and true-up policies with your provider—actual savings can vary by billing cycle and regulation.

FAQ
How do I include utility delivery charges?
Add the per-kWh portion of delivery charges to the retail rate input so the discount reflects the full avoided cost.
Can I model credit banking?
Estimate the average credits you apply in high-usage months and enter that kWh figure—banked credits simply shift the timing, not the blended savings rate.
What if my program takes an admin fee?
Add the fee to the subscription price per kWh so the calculation captures all charges deducted before credits hit your bill.
Does the tool handle time-of-use rates?
Approximate time-of-use savings by entering a weighted-average retail rate that reflects when your credits offset usage.
Additional Information
- Outputs assume credits and subscription charges apply to the same kWh volume each month.
- Retail rate comparison helps estimate how community solar savings stack up against supply charges on your bill.
- Negative net savings indicate the subscription price exceeds the credit value—renegotiate or reduce allocation if that happens.
