A 4 square feet area for (meter, disconnect & inverter) equipment adjacent to the electrical service panel or near the proposed collector panel space. 2. The best roof space available for accommodating PV solar collector panels with capacity for collector dead loading (typically 4 lbs/SF). 3. A minimum 3,800 volt-ampere PV electrical load entry on the Service Load Calculation (Show as a continuous load of 15.8 A). 4. An Electrical Panel Schedule with a 240 volt circuit breaker space labeled "reserved for Photo Voltaic". See electrical comments.

FOUNDATION PLANS:

1. Locate and detail all footings for interior bearing walls, R401.2.
2. Show exterior footings at least 12" below the undisturbed ground surface, R403.1.4. Update detail #1, 2 & 4/S2.
