  • "Quixotic was an excellent choice for us and helped in coming up with the best designs given the constraints of our roof and our budget. In this process we decided on a 20 kW photovoltaic system and a 4 collector solar hot water system. They were able to work with existing roof dunnage that allowed us to obtain extra points within the Leeds rating system. This all required very high caliber engineering, which they were able to provide. "
    — Executive Director, Staten Island Nonprofit
