A site surveyor performed site visit and obtained site photos. I have reviewed the photo of the main service panel, and systems of similar panel of 20 space - 40 circuits max with label in the past and thus conclude: The existing residential electrical main panel is Siemens— MC204OB1200ESC which has bus rating of 200A and main circuit breaker of 200A (Center -fed). Main circuit breaker for this solar PV system has been derated to 175A which satisfies 2016 CEC article 690 and 705.12(D) requirements. Should you have any questions, please feel free to contact me at the information listed below. Respectfully, Chi Fung Leung, P.E.

After review, I certify that the roof structure has sufficient structural capacity for the applied PV loads. All PV mounting equipment shall be designed and installed per manufacturer's approved installation specifications. If you have any questions, don't hesitate to contact.
