We read the public complaint records of ten solar companies across eight states, sorted what actually went wrong, and wrote the answers. No company is named — these are patterns, and plenty of solar is installed well.
Sources are public complaint records published by the recipient, plus published tax-law changes and industry closure data. Quotes are verbatim and attributed no more specifically than by state. Nothing here is tax, legal or financial advice — verify anything affecting your money with a qualified professional.
