Spruce Power now tells me my Prepayment/Buy Out price will include "Incentive costs" and "Residual Equipment Value." These items are not cited in the original NRG contract. Houston Texas

 I signed a contract with NRG in 2015 to install solar panels on my home.  The contract was for 20 years with a "buy out" option on the 7th anniversary (1 Sep 2022) for $12, 007.86 or, a one-time prepayment of $9987.29 based on a 4.5% interest rate, plus taxes. 

In about 2020, my contract was sold to Spruce Power.  Spruce Power now tells me my Prepayment/Buy Out price will include "Incentive costs" and "Residual Equipment Value." THese costs amount to almost $4000.00 in addition to the base amount. 

These items are not cited in the original NRG contract and were not part of anything I ever agreed to.
