"Our heater stopped functioning on Nov 27, 2023 and we called Petro who had done the maintenance on it before and replaced a motor two years ago. They were responsive and a technician came two days later. He worked for 3 hours without explaining what the problem was. Then said he needed to replace the motor. He fixed the problem and left without much explanation. Two days later a bill of $2500 came via email. No explanation, no break-down. I called 4 times over the last 20 days, spoke to 4 different reps and was promised that a supervisor will contact me with the bill details. Nothing happened. Irresponsible customer service and unprofessional behavior. They show all the symptoms of big, bureaucratic, and indifferent service company. I would not recommend Petro if you have options of more personalized services."

FAQs for solar panel installation projects in Watertown, MA

Annual inspections are recommended for residential solar systems, though specific needs vary based on several factors. Newer installations in moderate climates require less frequent professional evaluation, while systems over a decade old or those in harsh environments benefit from more regular attention. Always arrange an inspection following severe weather events that might have damaged components or affected system performance.

Pre-inspection cleaning isn't necessary, as evaluating the current condition of your panels is part of the assessment process. Professional inspectors can effectively examine systems regardless of cleanliness level, as accumulation patterns often provide valuable diagnostic information. However, if panels are completely obscured by heavy debris, bird droppings, or other materials that prevent visual examination of the surface, a basic rinse might be helpful before the scheduled inspection.

A comprehensive solar inspection examines all system components, including panels, wiring, mounting hardware, and inverters. Technicians check for physical damage like cracks or delamination, evaluate electrical connections for corrosion or looseness, and assess overall system performance against expected output levels. The inspection may also verify that safety systems are functioning correctly and that the installation complies with applicable codes and standards.

While traditional manual inspections are effective for most residential systems, specialized inspection methods may provide advantages for certain installations. Factors to consider include system size, roof complexity, accessibility challenges, and safety considerations. For multi-story homes or commercial installations where roof access is difficult or potentially hazardous, alternative inspection approaches offer improved documentation and reduced risk, though potentially at a higher cost.
