First off I am NOT an attorney and obviously can NOT give any type of legal council itself. However, what I can do is 'better prepare you' BEFORE you to talk to an attorney about your home solar situation. I have myself had to seek legal council concerning the crooked installation company that 'attempted' to install my solar and electrical system upgrade. What I can do is brief you on what a lawfirm looks at when handling a lawsuit against a solar instalation / sales company because my own legal case had legal standing. I can also provide you with a referal to one of the best lawfirms in the state that handles these types of solar contractor cases.
VERY IMPORTANT: Regardless of your status with a solar contractor, everyone either in the middle of a solar home system negotation or, considering home solar energy / battery storage for their home, need to read and understand Colorado's recent solar / battery storage consumer protection legislation in the state of Colorado. As a renewable energy consumer, you need to read ALL 21 pages and understand your right to full transparency in this space.
