Yes, you can still claim the Residential Clean Energy Credit for your solar panels, even if the installation company filed for bankruptcy. The credit may allow you to claim 30% of the installation costs (including labor and materials) if the panels were installed and operational last year.
Keep all documentation, including invoices, receipts, and warranties, as these are critical for claiming the credit and managing future maintenance. If warranties or maintenance were provided by the bankrupt company, you may need to find another provider. For more details, visit the IRS Residential Energy Efficient Property Credit page.
