Thank you to Fred for reviewing my solar panel quotes and for helping me understand what it all meant. He put all the data in a chart so they could be compared against each other. He gave me suggestions and questions to ask that would be important to know before deciding what was the best choice. His input and knowledge helped me greatly when it was time to choose a company for my solar needs. His independent review was exactly what I needed. —Meredith Herzog
