Solar panels do help you with SSc7.2, in the sense that they are considered appurtenances and are not counted as part of your roof area. So use of solar panels effectively reduces the area that you need to consider for other measures.

does anyone know if the same applies to a green roof application as well?

Denise, green roofs are a key way to earn SSc7.2. I'm not sure if that's your question, though -- can you clarify?

sorry, i meant for option 1 of ssc7.2. If I go the reflective materials route, am i able to not count green roof and photovoltaic panels as part of my total roof area?

Denise, Option 3 is a combination of Options 1 or 2. So it's not either/or.

To clarify, We have existing solar roof shingles which cover approximately 50% of our roof. Are solar shingles still considered appurtenances? Because of the slope and the weight load we cannot do the green roof option, though we are considering the white roof option for the other portion of it. Thanks!

That should work - your solar shingles in this case would be considered mechanical equipment, which you subtract from your total roof area, and use white/ high SRI roof for 75% of the remainder.
