I signed a contract with Solar Mosaic LLC XX/XX/XXXX to have solar panels installed by XXXX XXXX XXXX XXXX 
The first installment of {$44000.00} was paid to XXXX XXXX XXXX by Solar Mosaic XX/XX/XXXX. 
After contacting XXXX XXXX XXXX XXXX times they finally showed up to install the system XX/XX/XXXX to XX/XX/XXXX. These installers had no idea what they were doing and caused {$18000.00} worth of damage to the property. I promptly called Solar Mosaic about the problems on XX/XX/XXXX asking them to pay the XXXX and the issues I was having. XXXX Mosaic that very evening paid XXXXXXXX XXXX XXXX in full to the amount of {$29000.00} even after telling me that they would not. 
Since then all I get out of them is that they were there to help me with my home improvement and that I need to contact XXXX XXXX XXXX with my problems. 
Here is a copy of the letter sent to both parties. 
To whom this may concern On XX/XX/XXXX, your crew showed up on site to install the solar panel system on my property. I have several issues pertaining to this installation. First off, I never heard from whoever the project manager on this job is. I did get a call from a woman to make sure that they did show up on site. She stated that she would send me her contact information which she never did. 
The system is not installed per the plans or in the correct location. The footprint is supposed to be XXXX XXXX wide and XXXX XXXX deep. It is XXXX XXXX wide and only XXXX XXXX deep. This XXXX creates and issue with getting to the lower half of the property. The azimuth is correct while the tilt is at XXXX degrees. Not at the XXXX degrees per plans and not optional for this location. The system was also installed in freezing conditions and the concrete poured shows signed of thermal cracking already. Wind chill of XXXX degrees less than 48 hours after pouring. The remaining footing was poured in these freezing conditions. Hole depth is only XXXX inches and not XXXX feet per plans. No cross bracing per plans as well. This has also led to the array moving during high winds. My insurance company will not insure until the array is installed correctly. 
In running the lines to the house from the array they cut through the electrical going to our hot tub. I was called right away. I explained what it was going to and was assured that they would fix it right away. It wasnt until later that day when they drove a steel wrecking bar through a pool line and pool lights that I found out that the electrical was not repaired. By this time the hot tub was frozen, and lines ruptured internally. This can not be repaired and only replaced. The area of sidewalk that they cut through will have to now be removed to make repairs to the pool light and high-pressure vacuum line.

They have left this property in a mess. Trash all over the property, Open pits, and rental equipment still here. 
I look forward to hearing your remedy and completion date as soon as possible. 
They did show up on XX/XX/XXXX. XXXX XXXX XXXX made the system worse, never repaired any of the problems. To this day the application for installing the system has never been completed and the system has failed inspections.
