Sustainable Energy Systems review: Solar panel installation dismount/remount

Unethical and Extortionist practices - 14 months ago, my wife and I had solar panels installed on our home. The contract was brokered through a third-party (Zuna Solar - based in Texas). The installation went well, and everything is operating as it should. However, during August 2023, we experienced hail damage to our roof which has resulted in leaking that is slowly growing and causing damage to our living room ceiling. We had the roof inspected and confirmed the best way to deal with the leak is to have the roof replaced. We filed a claim with our homeowner's insurance and have had our claim approved and funded. With these funds, we contracted with a Northern Virginia roofing company to replace the roof. In order for this to occur, we need to have the solar panels dismounted, and then remounted after the roof replacement is completed. This is provided for in the contract on page 7, in the paragraph with the heading "Removal and Reinstall". Please note that the estimated cost on the contract is listed as "the greatest of $135 per panel or $2,700", although the contract also states this is subject to change. When we contacted Sustainable Energy Systems, they initially provided an estimate for the dismount/remount for a figure of $13,800 (drastically higher than "the greatest of $135 per panel or $2,700" figure provided in the installation contract), then went on to state that they would perform the work only if we canceled our contract with our current roofing company and paid SUSTAINABLE ENERGY SYSTEMS, LLC to perform both the roof replacement AND the solar panel dismount/remount. I refused to accept either the radically inflated cost for the dismount/remount work or to cancel my contract with our current roofer (we have already paid a 30% deposit), so we are no longer in discussions with Sustainable Energy Systems. I will never do business with them again due to these unethical and extortionist business practices.
