Site Assessment

Garima Yadav December 15, 2020

In Site Assessment, you demonstrate the value of an on-site inspection of a residential solar customer’s home. You teleport around the home to complete a checklist that will provide critical additional information for your company system designers to include along with any remote aerial evaluation they may do. You perform a detailed examination of the roof surfaces and note the types of obstructions and poor roof conditions that may affect module placement. You assess any dangerous ground or roof situations. You gather critical electrical panel parameters that may constrain inverter sizing or dictate the need for circuit breaker adjustments by the install crew. And you examine inside the attic, something no aerial based software can possibly do for you.
